In this way, the remote control device 200 can receive an input of the user, and control the electronic device 100 to display the corresponding display content.

Here, the input box 402 is marked, and the remote control device 200 can receive user input (e.g., pressing, double clicking, etc.) on the confirm key 201E, controlling the electronic device 100 to display a keyboard region 405 as shown in fig. 4B.

As shown in fig. 4B, the electronic device 100 may display a keyboard region 405 on the interface 401. The keyboard region 405 may include one or more display regions that may include, but are not limited to, display region 405A, display region 405B, display region 405C, display region 405D, display region 405E, display region 405F, display region 405G, and display region 405H. One or more characters may be included within each of the one or more display areas. Here, as shown in fig. 4B, the characters displayed in the keyboard area 405 are characters of a first character set, where the characters of the first character set are pinyin letters, and the user can select the pinyin characters through the keyboard area 405 to perform an input operation of chinese characters. The display area 405A includes 3 characters, and the 3 characters are: "A, B, C", … …, the display area 405H includes 4 characters therein, the 4 characters being: "W, X, Y, Z". The electronic device 100 may also display a cursor 403 in the input box 402, the cursor 403 may be used to indicate the location of the input character in the input box 402.

Alternatively, the electronic device 100 may display more than the keyboard region 405, and the electronic device 100 may also display a homepage icon 406, a power icon 407, a return icon 408, a voice icon 409, a menu icon 410, and the like. The icons correspond to partial keys on the remote control device 200, e.g., the function of the home icon 406 corresponds to the home key 202 of the remote control device, and the user may select the home icon 406 via the home key 202. The icons may be displayed in area 404 along with keyboard area 405.

Optionally, the electronic device 100 may also display a chinese prompt that may be used to prompt the user to enter chinese text via the keyboard region 405. For example, the chinese prompt may be: "Chinese".

It should be noted that, the keyboard area displayed by the electronic device 100 includes m display areas, when the touch pad of the remote control device 200 receives a touch input from a user, the location information at the touch point of the user may be sent to the electronic device 100, and the electronic device 100 may determine, based on the location information, a display area corresponding to the location information and mark the display area.

Here, it may be understood that the touch pad is divided into m touch areas corresponding to m display areas, and when a user touch point is placed in the touch area, the remote control device 200 may control the electronic device 100 to mark the display area corresponding to the touch area. For example, if the keyboard region includes 8 display regions as shown in fig. 4B, it is understood that the touch pad 201 is also divided into 8 touch regions, the display region 405A is located at the upper right corner of the keyboard region 405, and the touch region corresponding to the display region 405A is also located at the upper right corner of the touch pad. It should be noted that the touch area is merely for convenience of describing the introduced concept, and the touch pad is not actually divided into m display areas.

The remote control device 200 detects that the user is in contact with the touch pad 201, and the contact point is located at a position corresponding to the display area 405H in the touch pad 201, where the position of the contact point may be shown as a gray dot in fig. 4C. The remote control device 200 may control the electronic device 100 to display a display area 405H as shown in fig. 4C.

As shown in fig. 4C, since the remote control device 200 detects that the contact point of the user with the touch pad 201 is located at a position corresponding to the display area 405H in the touch pad, the remote control device 200 can control the electronic device 100 to mark the display area 405H. Here, the electronic device 100 marks the display area 405H includes thickening characters in the display area 405H, changing the color of the display area 405H so that the display pattern of the display area 405H is different from the display pattern of other display areas (e.g., the display area 405A) in the keyboard area. It is understood that this marking is merely an example, and is not limited to thickening fonts, changing the color of the display area, and the electronic device 100 may mark the display area by other means, such as highlighting the display area, expanding the size of the display area, etc., which are not limited in this embodiment of the present application.

The remote control device 200 may, upon detecting that the contact point of the user with the touch pad 201 as shown in fig. 4D moves to a position corresponding to the display area 405A in the touch pad, cancel the marking of the display area 405H and mark the display area 405A as shown in fig. 4D.

When the electronic device 100 displays the display area 405A as shown in fig. 4D, the remote control device 200 may receive a pressing input of the user against the touch pad 201 as shown in fig. 4E, and control the electronic device 100 to select a character in the display area 405A. When the character in the display area 405A is selected, the electronic device 100 may display the input character 411 as shown in fig. 4E. When the remote control device 200 receives a pressing input from the user to the touch pad 201, the pressing position of the user is a position of the touch pad 201 corresponding to the display area 405A. Note that, the input of the character selected in a certain display area may be other input, for example, a double click input, a long press input, or the like, which is not limited in the embodiment of the present application.

As shown in fig. 4E, an input character 411 is displayed in the input box 402, where the input character 411 may include characters in the selected display area, and if n display areas are selected, the input character 411 includes 1 character in each of the n display areas, and n is a positive integer. Here, the input character 411 includes one character, for example, a character 'a', in the display area 405A. In some examples, the input character 411 has the most commonly selected character in the display area displayed therein. The most frequently selected character may be the character selected most frequently in a period of time, or the most recently selected character, etc. It will be appreciated that as the input character 411 is displayed in the input box 402, the cursor 403 moves to the right of the input character 411. In some embodiments, the input character 411 of the electronic device 100 is a pinyin consisting of pinyin letters in the selected plurality of display areas. Alternatively, the pinyin is the most commonly used pinyin or the most recently selected pinyin.

The electronic device 100 also displays a pinyin field 412, the pinyin field 412 being located below the input box 402, the pinyin field 412 being operable to display pinyin based on characters of a first selected one of the display areas that have been selected and characters of a subsequent display area. The pinyin field 412 may also be used to display all characters based on a first selected one of the display areas that have been selected. Here, since only the display area 405A is selected, the pinyin field 412 displays three characters in the display area 405A.

It should be noted that, when the pinyin composed of the characters of the first selected one or more display areas among the already selected display areas is selected, or the text corresponding to the characters of the first selected one or more display areas among the already selected display areas is selected, the pinyin field 412 will display the pinyin composed of the characters of the earliest selected display area among the already selected display areas other than the one or more display areas and the characters of the subsequent display areas, and the characters of the display areas.

The electronic device 100 may also display a text field 413, the text field 413 being located below the pinyin field 412, the text field 413 may be used to display words derived based on the characters in the display area that have been selected. Here, the display area 405A is selected, and the character bar 413 displays a kanji whose initial is the pinyin letters in the display area 405A, for example, kanji 'o' whose initial is the pinyin letters 'a', 'c', kanji 'no' whose initial is the pinyin letters 'b', and 'c'. The content displayed in the text field 413 is merely an example, and the text field configuration should not be limited. Alternatively, the text field 413 may also display an association word, an error correction word, or the like obtained based on the character of the selected display area.

When the electronic apparatus 100 displays the input character 411 as shown in fig. 4E, the remote control apparatus 200 may cancel marking the display area 405A and mark the display area 405G when detecting that the contact point of the user with the touch pad 201 moves to a position corresponding to the display area 405G in the touch pad. Thereafter, the remote control device 200 may receive a pressing input of the user against the touch pad 201 as shown in fig. 4F, and control the electronic device 100 to select the character in the display area 405G. When the character in the display area 405G is selected, the electronic device 100 may display the input character 411 as shown in fig. 4F.

As shown in fig. 4F, entering the character 411 may include displaying the character in the selected display area. Here, the input character 411 includes one character in the display area 405A and one character in the display area 405G, for example, 'bu'. In some examples, the input character 411 may be used to display the leftmost pinyin in the pinyin field 412.

Here, the pinyin field 412 displays pinyin in which the letter in the display area 405A is the pinyin first letter and the character in the display area 405G is the second letter of pinyin. The pinyin field 412 also displays characters in the display area 405A. The text field 413 includes words derived based on the input character 411.

Similarly, the remote control device 200 may receive the input from the user for the touch pad 201, and control the electronic device 100 to display more pinyin letters. For example, after the electronic device 100 displays the input character 411 shown in fig. 4F, the remote control device 200 may receive the user's input to the positions on the touch pad 201 corresponding to the display area 405H, the display area 405C, the display area 405B, the display area 405A, and the display area 405E in order, and control the electronic device 100 to display the input character 411 shown in fig. 4G.

As shown in fig. 4G, the input character 411 of the electronic device 100 includes a character combination of all display areas that have been selected. The content displayed in the pinyin field 412 is the same as the content displayed in the pinyin field 412 in fig. 4F. The character field 413 displays a phrase obtained based on the display area 405A, the display area 405G, the display area 405H, the display area 405C, the display area 405B, and the display area 405A.

Therefore, by using the remote control method provided by the embodiment of the application, the user does not need to switch one character at a time through the direction key, so that complicated operation steps for inputting the characters are reduced, and the speed of inputting the characters by the user is improved.

In some embodiments, the input characters are displayed in the input box of the electronic device 100, and the remote control device 200 may receive a deletion input from the user, and control the electronic device 100 to delete the input characters in the input box. Wherein the delete input may be a left-sliding input.

For example, the electronic device 100 displays an input character 411 as shown in fig. 4G, where the input character 411 includes pinyin: "buzhidao". The remote control device 200 may receive a left-hand slide input of the user with respect to the touch pad 201 as shown in fig. 5A, delete 1 character of the input characters, and as shown in fig. 5A, the input character 411 displayed by the electronic device 100 is deleted by the character 'o' in the display area 405E less than the input character 411 in fig. 4G. Note that since the delete input may trigger the electronic device 100 to deselect the display area 405E, the input character 411 will no longer include the characters of the display area 405E. The phrase in the text field 413 is changed, and here, a word obtained based on the characters in the display area 405A, the display area 405G, the display area 405H, the display area 405C, the display area 405B, and the display area 405A is displayed in the text field 413.

In some embodiments, the input characters are displayed in the input box of the electronic device 100, the remote control device 200 may control the electronic device 100 to delete 1 input character when receiving the continuous deletion input of the user, and the remote control device 200 may control the electronic device 100 to delete 1 input character every first deletion period (e.g., 0.5 ms) until the remote control device 200 receives the deletion cancellation input of the user or the characters in the input box of the electronic device 100 are all deleted during the detection that the user does not leave the touch pad 201. The continuous deletion input may be an input that slides leftwards on the touch pad 201 and stays on the touch pad 201 for a time exceeding a first stay time period (e.g., 1S). During the time when the remote control device 200 detects that the user is staying on the touch pad 201, the remote control device 200 may control the electronic device 100 to delete 1 input character every first deletion period.

When the remote control device 200 detects that the user leaves the touch pad 201, the control electronic device 100 stops the character deleting operation. Here, the input that the user leaves the touch pad 201 is a cancel delete input.

Stated another way, the remote control device 200 may control the electronic device 100 to delete 1 input character upon receiving the continuous deletion input of the user, and during the time when the remote control device 200 receives the continuous deletion input, may control the electronic device 100 to delete 1 input character every first deletion period (e.g., 0.5 ms) until the characters in the input box of the electronic device 100 are all deleted.

Alternatively, the continuous deletion input may be understood as an input that slides to a specified position on the touch pad in a specified direction (e.g., left direction) and is touched for a long time at the specified position. During the reception of the continuous deletion input by the remote control device 200, the electronic device 100 is controlled to delete 1 character in the input box every 1 deletion period until all characters in the input box are deleted. In some examples, the plurality of deletion durations may be different, for example, the 1 st deletion duration may be 1s and the 2 nd and subsequent deletion durations may be 0.5s. In this way, it is possible to avoid the user from erroneously touching the remote control device 200, resulting in the electronic device 100 performing a continuous deletion operation. For another example, the 1 st deletion period may be 1s, the 2 nd deletion period may be 0.5s, the 3 rd deletion period may be 0.4s, and then the value of each deletion period is smaller than the value of the first 1 deletion period, so that a plurality of characters may be deleted more rapidly.

For example, the electronic device 100 displays an input character 411 as shown in fig. 4G, where the input character 411 includes pinyin: "buzhidao". The remote control device 200 may receive an input from the user that is directed to the left slide of the touch pad 201 and stays on the touch pad 201, and control the electronic device 100 to sequentially delete the characters in the input box 402. When the electronic apparatus 100 sequentially deletes the characters of the display area 405E, the display area 405A, the display area 405B, and the display area 405C in the input box 402, the remote control apparatus 200 detects that the user leaves the touch pad 201, and the remote control apparatus 200 controls the electronic apparatus to stop the deletion operation. The electronic device 100 may display the input character 411 shown in fig. 5B.

As shown in fig. 5B, the input character 411 displayed by the electronic apparatus 100 includes only characters of the display area 405A, the display area 405G, the display area 405H, and the display area 405C. Similarly, the phrase in the text field 413 is changed, and here, the text field 413 displays a word obtained based on the characters in the display area 405A, the display area 405G, the display area 405H, and the display area 405C.

In some embodiments, when an input character is displayed in an input box of the electronic device 100, the remote control device 200 may receive a cursor movement input from a user, controlling a position of a cursor of the input box of the electronic device 100 between the input characters. The remote control device 200 may receive an input of a long touch by a user and then move left, and control a cursor of the electronic device 100 to move left; the remote control device 200 may receive a user's long touch and then move right input to control the cursor of the electronic device 100 to move right. In this way, it is possible to facilitate deletion of unnecessary partial characters and insertion of characters at specified positions.

In some examples, the remote control device 200 may switch the display style of the cursor from the first style to the second style upon receiving a long touch input by the user for the touch pad 201. For example, the cursor pattern is transformed from the solid line segment (i.e., the first pattern) shown in fig. 4G to the broken line segment (i.e., the second pattern) shown in fig. 6A. In this way, the electronic device 100 may prompt the user to move the cursor of the electronic device 100 by moving left/right on the touch pad 201 by changing the display style of the cursor. When the remote control device 200 detects that the user leaves the touch pad 201, the display style of the cursor may be switched from the second style back to the first style. The long touch input may be an input to stay in the first area of the touch pad 201 for a second stay period (for example, 1 s). In some examples, the first area may be an area of the touch pad 201 where the confirm key 201E is located, or the first area may be an entire area of the touch pad 201.

For example, the electronic device 100 displays the input character 411 and the cursor 403 as shown in fig. 4G, where the input character 411 includes pinyin: "buzhidao". The cursor 403 is positioned to the right of all characters of the input character 411. The remote control device 200 may receive a long touch input for a touch pad by a user as shown in fig. 6A, and control the electronic device 100 to display a cursor 403 as shown in fig. 6A. The cursor 403 shown in fig. 6A is different from the cursor 403 shown in fig. 4G in display style.

The electronic device 100 may also cancel the display of one or more of the keypad areas 405 and display a directional icon as shown in fig. 6A when it receives a control signal for moving the cursor position from the remote control device 200. The direction icons include a left direction icon 601 and a right direction icon 602. The directional icon may be used to prompt the user to move left and right on the touch pad 201 to change the position of the cursor 403 at the input box 402.

The remote control device 200 may receive an input that the user moves left on the touch pad 201 as shown in fig. 6B, control the cursor 403 of the electronic device 100 to move left, and when the cursor 403 moves to the position as shown in fig. 6B, the remote control device 200 detects that the user leaves the touch pad 201, and displays the interface 401 as shown in fig. 6C.

As shown in fig. 6C, the display style of the cursor 403 displayed by the electronic device 100 is the same as the style of the cursor 403 shown in fig. 4G. The position of the cursor 403 is located between the character 'o' and the character 'z', and if the remote control device 200 receives an input that the user selects a certain display area, a character corresponding to the display area may be added at the position of the cursor 403 (i.e., between the character 'o' and the character 'z'). If the remote control device 200 receives an input from the user to delete a character, the character to the left of the cursor 403 is deleted.

It will be appreciated that the user remains in contact with the touch pad 201 throughout the process of controlling the changing cursor pattern and moving the cursor position, as the remote control device 200 receives a user's cursor movement input.

The remote control device 200 may receive a pressing input to the left direction key 201B and move the position of the cursor 403 to the left, not limited to the long-touch left-slide/long-touch right-slide input described above. The remote control device 200 may also receive a pressing input for the right direction key 201D, moving the position of the cursor 403 toward the right. It will be appreciated that if the position of the cursor is to the far left of the input character, the cursor will not move to the left any more, and if the position of the cursor is to the far right of the input character, the cursor will not move to the right any more. Alternatively, when the electronic apparatus 100 receives a control signal for moving a cursor leftward (or rightward) transmitted from the remote control apparatus 200, a display style of a left direction icon (or a right direction icon) may be changed, for example, a size and/or a color of the left direction icon (or the right direction icon) may be changed, or the left direction icon (or the right direction icon) may be highlighted, or the like.

Alternatively, the electronic device 100 may not change the content displayed in the keyboard region during the time when the remote control device 200 may receive a cursor movement input of the user, controlling the position of the cursor of the input box of the electronic device 100 between the input characters. For example, when the electronic device 100 displays the input character 411 and the cursor 403 as shown in fig. 4G, and the electronic device 100 receives a control signal for moving the cursor position sent by the remote control device 200, only the display style of the displayed cursor 403 is changed, and the display content of the keyboard region 405 is not changed, that is, the electronic device 100 still displays the keyboard region 405 as shown in fig. 4G.

In some examples, the cursor movement input may be understood as an input that long touches and then slides in a specified direction, and if the specified direction is left, the remote control device 200 may control the electronic device 100 to move the cursor one character distance to the left each time the user is detected to slide left by the first distance. If the designated direction is right, the remote control device 200 may control the electronic device 100 to move the cursor by one character rightward every time the user right-slid first distance is detected.

In some embodiments, the input characters are displayed in the input box of the electronic device 100, and the electronic device 100 also displays a pinyin field. The remote control device 200 may receive a first pinyin-field switching input from a user, controlling the focus of the electronic device 100 to move from the input box to the pinyin field. The remote control device 200 may receive a second pinyin-field switching input from the user, controlling the focus of the electronic device 100 to move from the pinyin field to the input box. Thus, the user can control the focus of the electronic device 100 to switch from the input box to the pinyin field through the remote control device 200, and select pinyin. The user may also control the focus of the electronic device 100 to switch from the pinyin field to the input box, adding/deleting/replacing input characters through the remote control device 200.

After receiving the control signal that the remote control device 200 moves the focus from the input box to the pinyin field, the electronic device 100 may move the focus to the pinyin field, cancel displaying one or more display areas of the keyboard area, and display one or more directional icons in the keyboard area. Thus, the one or more directional icons may be used to prompt the user to move the location of the focus left or right, selecting a different pinyin.

Illustratively, the electronic device 100 is displayed with an input character 411 as shown in FIG. 4G. The remote control device 200 may receive a first pinyin field switching input of the user as shown in fig. 7A, and control the electronic device 100 to display the pinyin field 412 as shown in fig. 7A. Wherein the first pinyin field switching input is a press input for the confirm key 201E of the remote control device 200.

As shown in fig. 7A, the pinyin field 412 of the electronic device 100 is selected, and the display style of the pinyin field 412 shown in fig. 7A is different from the style of the pinyin field 412 shown in fig. 4G. Here, the color of the pinyin field 412 is changed from white to gray, not limited to changing the color of the pinyin field 412, and the electronic device 100 may alternatively surround the pinyin field 412 using a rectangular frame.

Pinyin column 412 includes one or more Pinyin options including Pinyin option 701A, pinyin option 701B, pinyin option 701C, pinyin option 701D, and Pinyin option 701E. The focus of the electronic device 100 is on the pinyin option 701A. The electronic device 100 may mark the pinyin option at the focus, e.g., the electronic device 100 may highlight the pinyin option at the focus, or the electronic device 100 may change the word size of the pinyin option at the focus and/or the background color of the pinyin option and/or the color of the characters of the pinyin option, etc., so that the pinyin option at the focus is different from the other pinyin options. Here, the electronic device 100 displays a pinyin option 701A having a color different from other pinyin options.

The electronic device 100 may also cancel the display of one or more of the keypad areas 405 and display one or more directional icons as shown in fig. 7A upon receiving a control signal from the remote control device 200 to move the focus to the pinyin field 412. The one or more directional icons may include, but are not limited to, a left directional icon 705 and a right directional icon 706. The left and right icons 705 and 706 may be used to prompt the user to slide left and right on the touch pad 201 or through the left/right direction keys 201B/201D to change the pinyin options of the mark.

Alternatively, when the electronic device 100 receives a control signal sent by the remote control device 200 to move the focus of the electronic device 100 to the left (or to the right), the display style of the left direction icon 705 (or the right direction icon 706) may be changed, for example, the size and/or color of the left direction icon 705 (or the right direction icon 706) may be changed, or the left direction icon 705 (or the right direction icon 706) may be highlighted, or the like.

In some examples, the electronic device 100 may not change the display style of the pinyin field 412, only the pinyin options that focus on are marked.

Note that the first pinyin-field switching input is not limited to the pressing input of the enter key 201E, and may be input by another user, for example, the first pinyin-field switching input may be a pressing input for the down direction key 201C, or the first pinyin-field switching input may be a sliding input on the touch pad 201, or the like. Preferably, the first pinyin field switching input is a press input for the enter key 201E.

When the focus of the electronic device 100 is located in the pinyin field 412, the remote control device 200 may receive a right-slide input from the user on the touch pad 201/a press input from the user for the right direction key 201D, moving the focus to the right.

As shown in fig. 7A, the pinyin option at which the focus of the electronic device 100 is located is pinyin option 701A. Pinyin option 701A is marked. The remote control device 200 may receive a user's right-hand slide input on the touch pad 201 as shown in fig. 7B, displaying the labeled pinyin option 701B as shown in fig. 7B. As the focus of the electronic device 100 moves to the pinyin option 701B, the pinyin option 701B is marked and the pinyin option 701A is unmarked. It will be appreciated that if the pinyin option of the focus of the electronic device 100 is the right-most pinyin option, the focus of the electronic device 100 cannot be controlled to move to the right by the remote control device 200.

Similarly, the remote control device 200 may receive a left slide input from the user on the touch pad 201/a press input from the user for the left direction key 201B, moving the focus to the left. For example, if the electronic device 100 displays the pinyin option 701B shown in fig. 7B, the remote control device 200 may receive a left-sliding input from the user on the touch pad 201, and display the labeled pinyin option 701A shown in fig. 7A. As the focus of the electronic device 100 moves to the pinyin option 701A, the pinyin option 701A is marked and the pinyin option 701B is unmarked. It will be appreciated that if the pinyin option of the focus of the electronic device 100 is the leftmost pinyin option, the focus of the electronic device 100 cannot be controlled by the remote control device 200 to move leftwards.

As shown in fig. 7B, the electronic device 100 displays a marked pinyin option 701B, and the remote control device 200 may receive a user press input for the confirm key 201E as shown in fig. 7C, displaying a right-angle quotation mark 712 as shown in fig. 7C.

As shown in fig. 7C, the input character 411 of the electronic device 100 includes pinyin for the pinyin option 701B. A right angle quotation mark 712 exists between the pinyin of the pinyin option 701B and other non-selected pinyin characters in the input character 411, the right angle quotation mark 712 being operable to separate the pinyin of the pinyin option that has been selected (or confirmed) from the non-selected (or confirmed) pinyin.

As Pinyin option 701B is selected, the content of Pinyin field 412 changes. Here, since the pinyin characters of the first 2 selected display areas in the pinyin field 412 have been confirmed, the pinyin string composed of the pinyin characters of the 3 rd selected display area, and the pinyin characters of the display areas selected after the 3 rd selected display area are displayed in the pinyin field 412. Here, the pinyin field 412 includes a pinyin option 711A, a pinyin option 711B, a pinyin option 711C, a pinyin option 711D, a pinyin option 711E, a pinyin option 711F, a pinyin option 711G, a pinyin option 711H, and a pinyin option 711I. Wherein pinyin option 711A is marked.

As pinyin option 701B is selected, the content of text bar 413 changes as well. Here, since pinyin characters of the first 2 selected display areas in the pinyin field 412 have been confirmed, one or more chinese characters corresponding to the confirmed pinyin string are displayed in the text field 413. The text field 413 also displays a word obtained based on the confirmed pinyin string and the character in the display area selected subsequently.

Alternatively, when the electronic device 100 displays the right-angle quotation mark 712 as shown in fig. 7C, the remote control device 200 may receive the user input for the return key 204, deselect the pinyin option 701A, and display the interface 401 as shown in fig. 7A. Thus, the remote control device 200 may control to cancel the selection input of the pinyin option, and may cancel the selection of the pinyin option when a certain pinyin option is selected by mistake, and reselect other pinyin options.

In some examples, when the pinyin characters of all the selected display areas are confirmed by the pinyin field, the electronic device 100 may cancel the display of the pinyin field and display only the text field including the word corresponding to the pinyin string of the input character. The focus of the electronic device 100 is located in the text field.

Alternatively, after the remote control device 200 controls the focus of the electronic device 100 to move to the pinyin field, the electronic device 100 may not change the content displayed in the keypad area, i.e., not change one or more display areas in the keypad area to the one or more directional icons.

The remote control device 200 may also receive a second pinyin field switching input from the user, moving focus from the pinyin field 412 to the input box 402. Wherein the second pinyin field switching input may be an input for the return key 204.

For example, when the electronic device 100 displays the pinyin field 412 shown in fig. 7A, or when the electronic device 100 displays the pinyin field 412 shown in fig. 7B, the remote control device 200 may receive a pressing input of the user for the return key 204, and control the electronic device 100 to display the pinyin field 412 shown in fig. 4G.

Note that the second pinyin-field switching input is not limited to the pressing input for the return key 204, and may be other user inputs, for example, the second pinyin-field switching input may be the pressing input for the up key 201A, or the second pinyin-field switching input may be the up-slide input on the touch pad 201, or the like. Preferably, the second pinyin field switching input is a press input for the return key 204.

In some examples, the one or more direction icons may also include an upper direction icon (e.g., upper direction icon 707 shown in fig. 7A) and a lower direction icon (e.g., lower direction icon 708 shown in fig. 7A). The up icon may be used to prompt the user to switch the focus of the electronic device 100 from the pinyin field to the input box through the up key 201A or through a slide up input on the touch pad 201. The down icon may be used to prompt the user to switch the focus of the electronic device 100 from the pinyin field to the text field by means of the down key 201C or by a slide down input on the touch pad 201.

In some embodiments, the input characters are displayed in the input box of the electronic device 100, and the electronic device 100 also displays pinyin and text fields. The focus of the electronic device 100 is located in the pinyin field. The remote control device 200 may receive a first text field switching input from a user, and control the focus of the electronic device 100 to move from the pinyin field to the text field. The remote control device 200 may receive a second text field switching input from the user, controlling the focus of the electronic device 100 to move from the text field to the input box. Thus, the user can control the focus of the electronic device 100 to switch from the pinyin field to the text field by the remote control device 200, and select a text. The user can also control the focus of the electronic device 100 to switch from the text field to the input box, adding/deleting/replacing input characters through the remote control device 200.

When the focus of the electronic device 100 is located in the text field, one or more directional icons may also be displayed in the keyboard area of the electronic device 100. In this way, the one or more directional icons may be used to prompt the user to move the location of the focus left or right, selecting a different text.

For example, when the electronic device 100 displays the pinyin field 412 shown in fig. 7A, or when the electronic device 100 displays the pinyin field 412 shown in fig. 7B, the remote control device 200 may receive a first text field switching input of the user shown in fig. 8A, and control the electronic device 100 to display the text field 413 shown in fig. 8A. The first text field switching input is a pressing input for the down direction key 201C of the remote control device 200.

As shown in fig. 8A, the text field 413 of the electronic device 100 is selected, and the display style of the text field 413 shown in fig. 8A is different from the display style of the text field 413 shown in fig. 7A (or fig. 7B). Here, the color of the text field 413 is changed from white to gray, not limited to changing the color of the pinyin field 412, and the electronic device 100 may alternatively surround the text field 413 with a rectangular frame.

The text bar 413 includes one or more text options including text option 801A, text option 801B, text option 801C, text option 801D, text option 801E. The focus of the electronic device 100 is on text option 801A. The electronic device 100 may mark the text item in focus, e.g., the electronic device 100 may highlight the text item in focus, or the electronic device 100 may change the font size of the text item in focus and/or the background color of the text item and/or the color of the characters of the text item, etc., such that the text item in focus is different from the other text items. Here, the electronic device 100 displays a text option 801A having a color different from other text options. In some examples, electronic device 100 may not change the display style of text bar 413, only marking the text option where the focus is located.

As shown in fig. 8A, the keyboard region displays one or more directional icons. The one or more directional icons may include, but are not limited to, a left directional icon 805 and a right directional icon 806. The left direction icon 805 and right direction icon 806 may be used to prompt the user to slide left and right on the touch pad 201 or through the left direction key 201B/right direction key 201D to change the marked text options.

Alternatively, when the electronic device 100 receives a control signal sent by the remote control device 200 to move the focus of the electronic device 100 to the left (or to the right), the display style of the left direction icon 805 (or the right direction icon 806) may be changed, for example, the size and/or color of the left direction icon 805 (or the right direction icon 806) may be changed, or the left direction icon 805 (or the right direction icon 806) may be highlighted, or the like.

Alternatively, after the remote control device 200 controls the focus of the electronic device 100 to move to the text field, the electronic device 100 may display a keyboard region 405 as shown in fig. 4G.

Note that the first text field switching input is not limited to the pressing input to the down direction key 201C of the remote control device 200, but may be input by other users, for example, the first text field switching input may be a double click input to the down direction key 201C of the remote control device 200, or may be a slide down input on the touch pad 201, or the like. Preferably, the first text field switching input is a pressing input for the down direction key 201C of the remote control device 200.

When the focus of the electronic device 100 is located in the text bar 413, the remote control device 200 may receive a right slide input from the user on the touch pad 201/a press input from the user for the right direction key 201D, moving the focus to the right.

As shown in fig. 8A, the text option at which the focus of the electronic device 100 is located is text option 801A. The text option 801A is marked. The remote control device 200 may receive a user's right-hand slide input on the touch pad 201 as shown in fig. 8B, displaying a labeled text option 801B as shown in fig. 8B. As the focus of the electronic device 100 moves to the text option 801B, the text option 801B is marked and the text option 801A is unmarked. It will be appreciated that if the text option of the focus of the electronic device 100 is the rightmost text option, the focus of the electronic device 100 cannot be controlled by the remote control device 200 to move further to the right.

Similarly, the remote control device 200 may receive a left slide input from the user on the touch pad 201/a press input from the user for the left direction key 201B, moving the focus to the left. For example, if the electronic device 100 displays the text option 801B shown in fig. 8B, the remote control device 200 may receive a left-slide input from the user on the touch pad 201, and display the marked text option 801A shown in fig. 8A. As the focus of the electronic device 100 moves to the text option 801A, the text option 801A is marked and the text option 801B is unmarked. It will be appreciated that if the text option of the focus of the electronic device 100 is the leftmost text option, the focus of the electronic device 100 cannot be controlled by the remote control device 200 to move leftwards.

As shown in fig. 8B, the electronic device 100 displays a marked text option 801B, and the remote control device 200 may receive a user's pressing input for the confirm key 201E as shown in fig. 8C, displaying an input character 411 as shown in fig. 8C.

As shown in fig. 8C, the input character 411 of the electronic device 100 includes text of the text option 801B. Wherein, since the text option 801B is selected, the text option 801B is obtained based on the characters of all the selected display areas, and the characters of the selected display areas which are not converted into text are no longer included in the input characters 411. The electronic device 100 cancels the display of the pinyin field 412 and the text field 413.

In some examples, electronic device 100 displays labeled text options 801B as shown in fig. 8B. The remote control device 200 may receive a user's right-hand slide input on the touch pad 201 as shown in fig. 8D, displaying a labeled text option 801D as shown in fig. 8D. As the focus of the electronic device 100 moves to the text option 801D, the text option 801D is marked and the text option 801B is unmarked. The remote control device 200 may receive a user's pressing input for the confirm key 201E, displaying an input character 411 as shown in fig. 8E.

As shown in fig. 8E, the input character 411 of the electronic device 100 includes text of the text option 801C. Since the text option 801C is selected, the text in the text option 801C is obtained by the electronic device 100 based on the first 6 selected display areas, and the input characters 411 further include the characters in the 7 th display area and the characters in the 8 th display area. The electronic device 100 may separate the text in the input character 411 from pinyin by a right-angle quotation mark 811.

Here, since the input character 411 further includes the character of the 7 th display area and the character of the 8 th display area, the pinyin field 412 displays pinyin obtained based on the character of the 7 th display area and the character of the 8 th display area, and the letter character of the 7 th display area. The text bar 413 displays text obtained based on the 7 th display area character and the 8 th display area character, and the text bar 413 includes text options 821A, 821B, 821C, 821D, and 821E. The focus of the electronic device 100 is on the text entry 821A of the text bar 413, the text entry 821A being marked.

Alternatively, when the electronic device 100 displays the right-angle quotation mark 811 as shown in fig. 8E, the remote control device 200 may receive the input of the user for the return key 204, deselect the text option 801C, and display the interface 401 as shown in fig. 8A. Thus, the remote control device 200 can control to cancel the selection input of the text options, and can cancel the selection of a text option when a text option is selected by mistake, and reselect other text options.

The remote control device 200 may also receive a second text field switching input from the user, moving focus from the text field 413 to the input box 402. Wherein the second text field switching input may be an input for the return key 204. Alternatively, the second text field switching input may be a pressing input for the down direction key 201C, or the second text field switching input may be a sliding down input on the touch pad 201, or the like.

For example, when the electronic device 100 displays the text field 413 shown in fig. 8A, or when the electronic device 100 displays the text field 413 shown in fig. 8B, or when the electronic device 100 displays the text field 413 shown in fig. 8D, the remote control device 200 may receive a pressing input of the user against the return key 204, and control the electronic device 100 to display the text field 413 shown in fig. 4G.

In some examples, remote control device 200 may receive a third text field switching input from the user, controlling the focus of electronic device 100 to move from the text field to the pinyin field. The third text field switching input may be a pressing input for the up key 201A, or the third text field switching input may be a slide-up input on the touch pad 201, or the like.

In some examples, the one or more direction icons may also include an upper direction icon (e.g., upper direction icon 807 shown in fig. 8A) and a lower direction icon (e.g., lower direction icon 808 shown in fig. 8A). The up icon may be used to prompt the user to switch the focus of the electronic device 100 from the text field to the pinyin field through the up key 201A or through a slide-up input on the touch pad 201. The down icon may be used to prompt the user to switch the focus of the electronic device 100 from the text bar to the input box by the down key 201C or by a slide down input on the touch pad 201.

In one possible implementation, the electronic device 100 is displayed with a first input box. The remote control device 200 may control the electronic device 100 to display a keyboard region when receiving an input of a user selecting the first input box. Wherein the keyboard region includes one or more display regions, each of the one or more display regions having 1 character of the first set of characters displayed therein, the one or more display regions including the first display region. The remote control device 200 may control the electronic device 100 to mark a character of a first display area corresponding to a first position in the keyboard area when it is detected that a contact of a user stays at the first position of the touch pad. When the electronic apparatus 100 displays the character of the marked first display area, the remote control apparatus 200 may control the electronic apparatus 100 to display the character of the first display area in the first input box when receiving the confirmation input of the user.

In some embodiments, the number of display areas in the keyboard region is less than the number of characters in the first set of characters. The remote control device 200 may receive a character switching input of the user, and control the electronic device 100 to switch characters displayed in the display area. In this way, the electronic device 100 may display a portion of the characters in the first set of characters in a larger font size, making it easier for the user to see the characters displayed in the keyboard region of the electronic device 100. The electronic device 100 may also change the characters displayed in the keyboard region when receiving a control signal to switch characters, so that the electronic device 100 may display all characters in the first character set.

Specifically, the remote control device 200 may control the electronic device 100 to switch the character displayed in the display area in a counterclockwise (or clockwise) direction upon receiving the character switching input of the user. Also, the remote control device 200 may control the electronic device 100 to switch the characters displayed in the display area in a counterclockwise (or clockwise) direction at first intervals (e.g., 0.1 s) during reception of the character switching input. Specifically, the electronic apparatus 100 may move all characters to an adjacent display area in a counterclockwise (or clockwise) direction each time characters displayed in the display area are switched. After the display positions of the characters in the electronic device 100 are changed, the electronic device 100 cancels displaying the 1 st character in the first character set, and newly displays 1 character in the first character set after the last 1 character in the last 1 display area (or, the electronic device 100 cancels the last 1 character in the first character set, and newly displays 1 character in the first character set before the 1 st character in the 1 st display area). The sequence of the display areas and the sequence of the characters in the first character set may be preset. For example, the electronic apparatus 100 may have a display area located on the clockwise side of the top of the keyboard area as the 1 st display area and a display area located on the counterclockwise side of the top of the keyboard area as the last 1 display area. For example, if the characters in the first character set are pinyin letters, the electronic device 100 may be configured to display the 26 characters sequentially in alphabetical order. It should be further noted that, in the process of controlling the electronic apparatus 100 by the remote control apparatus 200 to perform the character switching operation in the counterclockwise direction, after the last 1 characters in the sequence are displayed in the last 1 display areas of the electronic apparatus 100, the electronic apparatus 100 may display the first 1 characters in the sequence in the last 1 display areas after the first interval time, or the electronic apparatus 100 may stop performing the character switching operation. When the remote control device 200 controls the electronic device 100 to perform the character switching operation in the clockwise direction, after the 1 st display area of the electronic device 100 displays the 1 st character in the sequence, the electronic device 100 may display the last 1 character in the 1 st display area after the first interval time, or the electronic device 100 stops performing the character switching operation.

Alternatively, the remote control device 200 may control the electronic device 100 to cancel displaying the current plurality of characters and display the plurality of characters after the plurality of character sequences (or before the plurality of character sequences) in the keyboard region upon receiving the character switching input of the user.

It can be appreciated that when the direction of character switching is counterclockwise, the electronic device 100 switches the characters in the first character set in positive order; when the direction of the character switching is clockwise, the electronic device 100 switches the characters in the first character set in a reverse order, for example, if the characters in the first character set are pinyin letters, the positive order is the order from the letter a to the letter z, and the reverse order is the order from the letter z to the letter a.

It should be noted that, the clockwise direction and the counterclockwise direction are only examples, and if the display areas are not arranged in the ring shape as shown in fig. 9A, the electronic device 100 may determine the direction of character switching according to the arrangement manner of the plurality of display areas. For example, if a plurality of display areas are arranged from left to right, the electronic device 100 may switch the characters in the display areas in a right to left (or left to right) direction.

Illustratively, the number of display areas in the keyboard area is m, and the number of characters of the first character set in the electronic device 100 is n, n being greater than m. The first m characters of n characters are displayed in the m display areas of the electronic apparatus 100, wherein the 1 st character is displayed in the 1 st display area, the 2 nd character is displayed in the 2 nd display area, … …, (m-1) th character is displayed in the (m-1) th display area, and the m-th character is displayed in the m-th display area.

Next, taking an example in which the remote control device 200 can control the electronic device 100 to switch the character displayed in the display area in the counterclockwise direction when receiving the character switching input of the user, it is exemplified how the electronic device 100 performs the character switching operation. The remote control device 200 may control the electronic device 100 to move the display position of the character in each display area in the counterclockwise direction upon receiving the character switching input of the user. Specifically, the remote control device 200 may control the electronic device 100 to cancel the display of the 1 st character, and display the 2 nd character in the 1 st display area, the 3 rd character in the 2 nd display area, … …, the (m-1) th character in the (m-1) th display area, and the (m+1) th character in the (m-1) th display area. Also, the remote control device 200 may control the electronic device 100 to perform an operation of moving the display position of the character in each display area in the clockwise direction every first interval time during reception of the character switching input. For example, the remote control device 200 may cancel the display of the 2 nd character displayed in the 1 st display area and display the 3 rd character in the 1 st display area, display the 4 th character in the 2 nd display area, … …, display the (m+1) th character in the (m-1) th display area, display the (m+2) th character in the m-th display area, and so on after a first interval time from a point in time when the 2 nd character is displayed in the 1 st display area during the reception of the character switching input by the electronic device 100.

The remote control device 200 may display the 1 st character in the mth display area after the first interval time if the nth character is displayed in the mth display area of the electronic device 100 during the reception of the character switching input, or the electronic device 100 may not perform the switching operation any more.

Stated another way, the character switching input may be understood as an input that slides in a specified direction (e.g., clockwise) to a specified position (e.g., a position on the touch pad corresponding to the last 1 display area) and is touched long at the specified position. The remote control device 200 controls the electronic device 100 to perform the character switching operation 1 time every time the user touches for 1 designated period of time. In some examples, the plurality of durations may be different, for example, the 1 st switching duration may be 1s and the 2 nd and subsequent switching durations may be 0.5s. In this way, it is possible to avoid the user from erroneously touching the remote control device 200, resulting in the electronic device 100 performing a character switching operation. For another example, the 1 st switching duration may be 1s, the 2 nd switching duration may be 0.5s, the 3 rd switching duration may be 0.4s, and then the value of each switching duration is smaller than the value of the first 1 switching duration, so that a plurality of characters may be switched more rapidly.

In some embodiments, remote control device 200 may receive a user's clockwise character switching input, control electronic device 100 switches the characters displayed in the keyboard region in a counterclockwise direction, and remote control device 200 may receive a user's counterclockwise character switching input, control electronic device 100 switches the characters displayed in the keyboard region in a clockwise direction. The clockwise switching input may be an input that slides clockwise in the keyboard region and is long touched, and the counterclockwise switching input may be an input that slides counterclockwise in the keyboard region and is long touched. Preferably, the clockwise character input may be an input of sliding clockwise to a first preset display area and long-touching, the counterclockwise switching input may be an input of sliding counterclockwise to a second preset display area and long-touching, the first preset display area may be a last 1 display area of the plurality of display areas (for example, a last display area of the keyboard area rotating clockwise from the twelve-point direction), and the second preset display area may be a 1 st display area of the plurality of display areas (for example, a first display area of the keyboard area rotating clockwise from the twelve-point direction).

In some examples, when the remote control device 200 detects an input that the user slides and touches for a long time, the time when the user touches the touch pad 201 is detected to be longer than the third dwell time, the remote control device 200 may transmit a control signal for instructing the electronic device 100 to perform character switching to the electronic device 100, and the electronic device 100 may perform the character switching operation upon receiving the control signal and perform the character switching operation again after a first interval time of each of the character switching operations. The remote control device 200 detects that the user leaves the touch pad 201, transmits a control signal for instructing the electronic device 100 to cancel performing the character switching operation to the electronic device 100, and the electronic device 100 may cancel performing the character switching operation when receiving the control signal. Or alternatively. The remote control device 200 may detect the input period in which the user slides and touches for a long time, after transmitting the character switching control signal instructing the electronic device 100 to execute the character switching control signal, the control signal is transmitted again at intervals of the first interval time until the remote control device 200 detects that the user leaves the touch pad 201, and no more instruction is transmitted to the electronic device 100 to instruct the electronic device 100 to execute the character switching control signal.

In some embodiments, the characters may be divided into characters of different character types. For example, characters may be divided into pinyin-type characters, english-type characters, numeric-type characters, symbol-type characters, and so forth. The characters displayed in the keyboard region may be pinyin characters. Thus, the user can type in Chinese characters on the electronic device 100 through the remote control device 200 and the keyboard region.

Illustratively, the electronic device 100 is displayed with an interface 401 as shown in FIG. 4A. The focus of the electronic device 100 is located at the position of the input box 402. The remote control device 200 may receive user input (e.g., pressing, double clicking, etc.) on the confirmation key 201E, controlling the electronic device 100 to display a keyboard region 405 as shown in fig. 9A.

As shown in fig. 9A, the keyboard region 405 includes 8 display regions, each of which displays one pinyin letter. Wherein, the 1 st display area displays the first 1 letter in the 26 Pinyin letters, and the 8 th display area displays the 8 th letter in the 26 letters. The 8 display regions are a display region 901A, a display region 901B, a display region 901C, a display region 901D, a display region 901E, a display region 901F, a display region 901G, and a display region 901H, respectively, the display region 901A being the 1 st display region, and the display region 9001H being the last 1 display region. Since the number of pinyin letters is 26, the number thereof is greater than the number of display areas in the keypad area 405. Thus, the first 8 letters of the 26 english letters are displayed in the keyboard region 405 shown in fig. 9A. The pinyin letters 'a', … … are displayed in the display area 901A, and the pinyin letters 'H' are displayed in the display area 901H.

The remote control device 200 may receive a clockwise character switching input of the user, control the electronic device 100 to move the display position of the pinyin letters in each display area in the counterclockwise direction, display the pinyin letters 'B', … … in the display area 901A, and display the pinyin letters 'I' in the display area 901H.

After a first interval of displaying pinyin letters 'B' in the display area 901A of the electronic device 100 during which the remote control device 200 receives the clockwise character switching input of the user, the electronic device 100 moves the display position of the pinyin letters in each display area in a counterclockwise direction, displaying the keypad area 405 as shown in fig. 9B.

As shown in fig. 9C, the electronic device 100 may also display a text field 921, where one or more text options are displayed, the text options including chinese characters or words based on the pinyin letters in the input box 402.

In some embodiments, remote control device 200 may receive a fourth text field switching input from the user, switching the focus of electronic device 100 from the input box to the text field. The fourth text bar switching input may be an input (e.g., a press input, a double-click input, etc.) to the down direction key 201C of the remote control device 200, or a slide-down input on the touch pad 201, or an input (e.g., a press input, a double-click input, etc.) to the confirm key 201E of the remote control device 200, etc. The remote control device 200 may receive a fifth text field switching input from the user, switching the focus from the text field to the input box. The fifth text field switching input may be an input (e.g., a press input, a double click input, etc.) for the up key 201A of the remote control device 200, or an up slide input on the touch pad 201, or a press input for the return key 204 of the remote control device 200, etc. When the focus of the electronic device 100 is located in the text field, the remote control device 200 may receive a text option switching input from the user, and control the electronic device 100 to switch the marked text option. Thus, the user can control the focus of the electronic device 100 to switch from the pinyin field to the text field by the remote control device 200, and select a text. The user can also control the focus of the electronic device 100 to switch from the text field to the input box, adding/deleting/replacing input characters through the remote control device 200.

Alternatively, when the focus of the electronic device 100 is located in the text field, one or more directional icons may be displayed on the keyboard region of the electronic device 100. In this way, the one or more directional icons may be used to prompt the user to move the location of the focus left or right, selecting a different text.

Illustratively, the electronic device 100 displays the text bar 921 shown in FIG. 9C. The remote control device 200 may receive a fourth text field switching input from the user, controlling the focus of the electronic device 100 to move from the input box 402 to the text field 921.

As shown in fig. 9D, the text field 921 of the electronic device 100 is selected, and the display style of the text field 921 shown in fig. 9D is different from the display style of the text field 921 shown in fig. 9C. Here, the color of the text field 921 is changed from white to gray, and the electronic device 100 may alternatively surround the text field 921 with a rectangular frame, not limited to changing the color of the text field 921.

The text field 921 includes one or more text options including text option 921A, text option 921B, text option 921C, text option 921D, text option 921E. The focus of the electronic device 100 is on the text selection 921A. The electronic device 100 may mark the text item in focus, e.g., the electronic device 100 may highlight the text item in focus, or the electronic device 100 may change the font size of the text item in focus and/or the background color of the text item and/or the color of the characters of the text item, etc., such that the text item in focus is different from the other text items. Here, the electronic device 100 displays a text option 921A having a color different from other text options. In some examples, the electronic device 100 may not change the display style of the text bar 921, only the text options that are in focus are marked.

Wherein the remote control device 200 can receive a right-slide input from the user on the touch pad 201/a pressing input from the user for the right direction key 201D, move the focus to the right, and mark the text option 921B. Similarly, when the electronic device 100 displays the marked text option 921B, the remote control device 200 may receive a left slide input from the user on the touch pad 201/a press input from the user for the left direction key 201B, move the focus to the left, and mark the text option 921A.

The remote control device 200 may receive a confirmation input of the user for the text options, and control the electronic device 100 to display the content of the text options in the input box. For example, the electronic device 100 displays the marked text option 921A, the remote control device 200 receives the user input (e.g., pressing) on the confirmation element 201E, and the remote control device 200 may control the electronic device 100 to display the content of the text option 921A in the input box 402: "just".

Wherein the keypad area 405 may display one or more directional icons. The one or more directional icons may include, but are not limited to, a left directional icon 925 and a right directional icon 926. The left direction icon 925 and the right direction icon 926 may be used to prompt the user to slide left and right on the touch pad 201 or through the left direction key 201B/right direction key 201D to change the marked text options.

Alternatively, when the electronic device 100 receives a control signal transmitted by the remote control device 200 to move the focus of the electronic device 100 to the left (or to the right), the display style of the left direction icon 925 (or the right direction icon 926) may be changed, for example, the size and/or color of the left direction icon 925 (or the right direction icon 926) may be changed, or the left direction icon 925 (or the right direction icon 926) may be highlighted, or the like.

Alternatively, after the remote control device 200 controls the focus of the electronic device 100 to move to the text field, the electronic device 100 may display a keyboard region 405 as shown in fig. 9C.

In some examples, the pinyin characters of the first character set may be divided into 8 character groups that include pinyin characters that may be referenced to the characters of the 8 display areas shown in fig. 4B. The keyboard region of the electronic device 100 may include a display regions, each of the a display regions displaying characters of one character set, a being less than 8. The remote control device 200 may receive a character switching input of a user, and control the electronic device 100 to switch characters displayed in the keyboard region. Taking a as 6 as an example, a specific step of switching characters displayed in the keyboard region is exemplified. The keyboard area displayed by the electronic device 100 includes 6 display areas, which can be regarded as the display areas 405A to 405F shown in fig. 4B. Upon receiving the character switching input, the remote control device 200 controls the electronic device 100 to display the character in the display area 405B shown in fig. 4B in the display area 405A, to display the character in the display area 405C shown in fig. 4B in the display area 405B, to display the character in the display area 405F shown in fig. 4B in the display area 405E, and to display the character in the display area 405G shown in fig. 4B in the display area 405F. During the reception of the character switching input by the user by the remote control device 200, after a first interval of time in which the character in the display area 405B shown in fig. 4B is displayed in the display area 405A of the electronic device 100, the electronic device 100 is controlled to display the character in the display area 405C shown in fig. 4B in the display area 405B, the character in the display area 405D shown in fig. 4B in the display area …, the character in the display area 405G shown in fig. 4B in the display area 405E, the character in the display area 405H shown in fig. 4B in the display area 405F, and so on. Thus, the electronic apparatus 100 can display a plurality of characters in one display area, reducing the number of times the user switches character operations.

Next, taking as an example that the remote control device 200 may cancel displaying the current plurality of characters and display the plurality of characters after (or before) the plurality of character sequences in the first character set in the keyboard area when receiving the character switching input of the user, the electronic device 100 is exemplarily described how the electronic device 100 performs the character switching operation. Illustratively, the number of display areas in the keyboard area is m, and the number of characters in the first character set in the electronic device 100 is n, where n is greater than m. The first m characters of n characters are displayed in the m display areas of the electronic apparatus 100, wherein the 1 st character is displayed in the 1 st display area, the 2 nd character is displayed in the 2 nd display area, … …, (m-1) th character is displayed in the (m-1) th display area, and the m-th character is displayed in the m-th display area. If n is equal to or greater than 2m, the remote control device 200 may control the electronic device 100 to cancel displaying the 1 st to m-th characters in the m-th display area, and to display the (m+1) -th character in the 1 st display area, the (m+2) -th character in the 2 nd display area, … …, the (2 m-1) -th character in the (m-1) -th display area, and the 2 m-th character in the m-th display area upon receiving the character switching input of the user. If n is greater than m and less than 2m, the remote control device 200 may control the electronic device 100 to display (n-m) th to n-th characters in the display area upon receiving a character switching input of the user. Specifically, the electronic apparatus 100 may cancel the display of the 1 st to m-th characters in the m-th display area, and display the (n-m) -th character in the 1 st display area, the (n-m+1) -th character in the 2 nd display area, … …, the (n-1) -th character in the (m-1) -th display area, and the n-th character in the m-th display area.

It is understood that if n is smaller than m, the electronic device 100 may display the n characters in the 1 st to n-th display areas and not display any characters in the (n+1) -th to m-th display areas.

Optionally, the electronic device 100 stores n characters, each corresponding to a display area. The electronic device 100 may display m display areas corresponding to the first m characters of the n characters in the keyboard area, and after receiving the character switching input of the user, the remote control device 200 may move the position of the display areas, cancel displaying p display areas, and newly add and display p display areas, where p is greater than zero and less than or equal to m.

In other embodiments, the character switch input may be an input that slides in a specified direction (e.g., clockwise, counterclockwise). The remote control device 200 may control the electronic device 100 to perform the character switching operation 1 time after receiving the character switching input. The character switching operation may be an operation of canceling the display of the character in the 1 st display area and displaying the character in the 2 nd display area in the 1 st display area, … displaying the character in the last 1 display area in the 2 nd display area and displaying the character after the character in the last 1 display area in the first character set in the last 1 display area, or an operation of canceling the display of the current plurality of characters by the electronic device 100 and displaying the plurality of characters after the plurality of character sequences (or before the plurality of character sequences) in the first character set in the keyboard area, which will not be described herein.

In other embodiments, the character switch input may be an input that slides in a specified direction (e.g., clockwise, counterclockwise). The remote control device 200 may decide the number of times of switching character operations based on the sliding distance. The remote control device 200 may control the electronic device 100 to perform the character switching operation 1 time every time it detects that the user slides the first distance to the third direction.

In some examples, the direction of the character switching input is direction a, and the electronic device 100 switches the characters of the first character set in a positive order. The direction of the character switching input is direction B, and the electronic device 100 switches the characters of the first character set in reverse order, the direction B being opposite to the direction a. For example, direction a is clockwise and direction B is counterclockwise. In some embodiments, the characters may be divided into characters of different character types. For example, characters may be divided into pinyin-type characters, english-type characters, numeric-type characters, symbol-type characters, and so forth. The remote control device 200 may receive a character type switching input of the user, changing the character type displayed in the keyboard region of the electronic device 100. Thus, typing different types of characters in the input box may be achieved by controlling the electronic device 100 to display the different types of characters in the keyboard region.

In some examples, the keyboard region of the electronic device 100 displays characters of a first set of characters that are pinyin-type characters, also known as pinyin letters or pinyin characters. The remote control device 200 may control the electronic device 100 to display characters of a second character set, which may be english-type characters, also referred to as english letters or english characters, in the keyboard region after receiving the character type switching input of the user.

The electronic device 100 is illustratively shown with an interface 401 as shown in fig. 4B, or an interface 401 as shown in fig. 9A. The remote control device 200 may receive a character type switching input as shown in fig. 10A, displaying a keyboard region 405 as shown in fig. 10A.

As shown in fig. 10A, the keyboard region 405 includes 8 display regions, each of which displays one english letter. The 8 display regions are a display region 1001A, a display region 1001B, a display region 1001C, a display region 1001D, a display region 1001E, a display region 1001F, a display region 1001G, and a display region 1001H, respectively, the display region 1001A being the 1 st display region and the display region 1001H being the last 1 display region. Since there are 26 english alphabets, the first 8 letters among the 26 english alphabets are displayed in the keyboard area 405 shown in fig. 10A.

The remote control device 200 may receive a user's clockwise character switching input, where the clockwise character switching input may be an input that slides toward the last 1 display area (here, display area 1001H) of the displayed keyboard areas and hovers over the display area for more than a third dwell period (e.g., 1 s). After receiving the clockwise character switching input, the remote control device 200 may control the electronic device 100 to display the letter of the (i+1) th display area in the i-th display area, i being greater than or equal to 1 and less than 8. Thereafter, 1 letter after the letter in the 7 th display area, i.e., the 9 th letter, among the 26 letters is displayed in the 8 th display area. And the letter of the (i+1) th display area is displayed again in the 8 th display area and 1 letter after the letter in the 7 th display area among the 26 letters is displayed in the m-th display area every a first interval period (e.g., 1 s) during which the remote control device 200 detects that the user does not leave the touch pad 201. Until the remote control device 200 detects that the user leaves the touch pad 201, the remote control device 200 controls the electronic device 100 not to change the characters displayed in the keyboard region any more. Alternatively, when the 26 th letter is displayed in the mth display area of the electronic device 100, the electronic device 100 does not change the character displayed in the keyboard area any more. In this way, the electronic device 100 may be controlled to display other english alphabets in the keyboard region such that the electronic device 100 supports the user to input any english alphabets among all english alphabets.

It will also be understood that the remote control device 200, upon receiving a clockwise character switching input from the user, may control the electronic device 100 to display the letter of the 2 nd display area in the 1 st display area, the letter of the 3 rd display area in the 2 nd display area, and so on, the letter of the 8 th display area in the 7 th display area, and the letter that is the latter of the letters moved to the 7 th display area in the 8 th display area. During the time when the remote control device 200 receives the clockwise character switching input, after the remote control device 200 controls the electronic device 100 to switch the display area of the letter, the remote control device 200 will again control the electronic device 100 to switch the display area of the letter every a first interval duration. Until the remote control device 200 detects that the user leaves the touch pad 201, the remote control device 200 controls the electronic device 100 not to change the characters displayed in the keyboard region any more. Alternatively, when the 26 th letter is displayed in the 8 th display area of the electronic device 100, the electronic device 100 does not change the character displayed in the keyboard area any more.

After receiving the clockwise character switching input, the remote control device 200 may control the electronic device 100 to move the positions of the symbols on the respective display areas in the counterclockwise direction, so that the electronic device 100 no longer displays the symbol of the 1 st display area, displays the symbol of the 2 nd display area in the 1 st display area, …, and displays the symbol of the 8 th display area in the 7 th display area. The electronic device 100 may also display a symbol in the 8 th display area that the electronic device 100 presets after the symbol in the 8 th display area has been shown. The remote control device 200 may also move the position of the symbol on the respective display areas in a counter-clockwise direction again at first interval durations (e.g., 1 s) during which it is detected that the user has not left the touch pad 201. Until the remote control device 200 detects that the user leaves the touch pad 201, the remote control device 200 controls the electronic device 100 not to change the symbol displayed in the keyboard region any more. Or, when the last 1 symbol set by the electronic device 100 is displayed in the mth display area of the electronic device 100, the electronic device 100 does not change the symbol displayed in the keyboard area any more. In this way, the electronic device 100 may be controlled to display other symbols in the keyboard region such that the electronic device 100 supports the user to input any of all the symbols.

Similarly, the remote control device 200 may receive a counterclockwise character switching input of the user, where the counterclockwise character switching input may be an input that slides toward the 1 st display area (display area 1201A) of the displayed keyboard areas and stays in the display area for more than a third stay period (e.g., 1 s). After receiving the counterclockwise character switching input, the remote control device 200 may control the electronic device 100 to move the positions of the symbols on the respective display areas in a clockwise direction, so that the electronic device 100 no longer displays the symbol of the 8 th display area, displays the symbol in the 7 th display area in the 8 th display area, …, and displays the symbol in the 1 st display area in the 2 nd display area. The electronic apparatus 100 may also display a symbol that the electronic apparatus 100 presets before the symbol in the 1 st display area has been shown in the 1 st display area. The remote control device 200 may also move the position of the symbol on the respective display areas again in a clockwise direction at first interval durations (e.g., 1 s) during which it is detected that the user has not left the touch pad 201. Until the remote control device 200 detects that the user leaves the touch pad 201, the remote control device 200 controls the electronic device 100 not to change the symbol displayed in the keyboard region any more. Or, when the 1 st symbol set by the electronic device 100 is displayed in the 1 st display area of the electronic device 100, the electronic device 100 does not change the symbol displayed in the keyboard area any more. Here, the division of the keyboard area 405 into 8 display areas is merely an example, and the keyboard area 405 may be divided into more or fewer display areas, which is not limited in the embodiment of the present application.

Optionally, the electronic device 100 may also display symbol prompting information, which may be used to prompt the user to enter a symbol through the keyboard region 405. For example, the symbol hint information may be: "symbol".

In some examples, the keyboard region of the electronic device 100 is displayed with symbol characters, and the remote control device 200 may control the electronic device 100 to display numeric characters in the keyboard region after receiving a character type switching input of the user.

Illustratively, when the electronic device 100 displays the keyboard region 405 as shown in fig. 12A, the remote control device 200 may receive a character type switching input of the user as shown in fig. 12A, displaying the keyboard region 405 as shown in fig. 12B. As shown in fig. 12B, a plurality of display areas, each of which has a number, are displayed in the keyboard area 405. When the remote control device 200 receives a touch input from a user for a position corresponding to a certain display area in the touch pad 201, the electronic device 100 may be controlled to mark the display area. When the remote control device 200 receives a pressing input from the user for a position corresponding to a certain display area in the touch pad 201, the electronic device 100 may be controlled to select the display area, and the electronic device 100 may be controlled to display the number of the display area in the input box.

Here, the keyboard region 405 includes 10 display regions, which are a display region 1211A, a display region 1211B, a display region 1211C, a display region 1211D, a display region 1211E, a display region 1211F, a display region 1211G, a display region 1211H, a display region 1211I, and a display region 1211J, respectively.

Here, the division of the keyboard area 405 into 10 display areas is merely an example, and the keyboard area 405 may be divided into fewer display areas, which is not limited in the embodiment of the present application. If the number of display areas of the keypad area 405 is less than 10, the electronic device 100 may display the numeric characters in the manner shown in fig. 12A.

Optionally, the electronic device 100 may also display numeric prompts, which may be used to prompt the user to enter numbers via the keypad area 405. For example, the digital cue information may be: "number".

In some embodiments, the keyboard region may display numeric characters and symbolic characters simultaneously.

It will be appreciated that the keypad area of the electronic device 100 displays symbolic characters, and the remote control device 200 may control the electronic device 100 to display numeric characters in the keypad area after receiving a user's character type switching input.

Note that, the control electronic device 100 is not limited to the case where the remote control device 200 receives the character type switching input, and switches from the pinyin character to the english character. When the remote control device 200 receives the character type switching input again, the control electronic device 100 switches from english characters to symbol characters. When the remote control device 200 receives the character type switching input again, the control electronic device 100 switches from the symbol character to the digital character. The order of the character types displayed by the electronic device 100 may be different. For example, when the remote control device 200 receives the character type switching input, the control electronic device 100 switches from pinyin characters to english characters. When the remote control device 200 receives the character type switching input again, the control electronic device 100 switches from english characters to digital characters. When the remote control device 200 receives the character type switching input again, the control electronic device 100 switches from a numeric character to a symbolic character or the like, which is not limited in the embodiment of the present application.

In some examples, if the input box of the electronic device 100 displays pinyin letters, the remote control device 200 may cancel displaying pinyin letters (and pinyin and text fields) and display the first text option of the text field or the first pinyin option of the pinyin field in the input box when receiving the character type switching input of the user and controlling the keyboard area of the electronic device 100 to display other types of characters. If the electronic device 100 displays an input box and an english letter, the input box of the electronic device 100 displays the english letter, and the remote control device 200 receives the character type switching input of the user, and when controlling the keyboard area of the electronic device 100 to display other types of characters, it may also control the electronic device 100 to cancel displaying the english letter and the english letter, and display the first english option of the english letter in the input box, or may also control the electronic device 100 to cancel displaying only the english letter.

In other examples, the character switch input and the character type switch input are the same, which may be collectively referred to as a character switch input. For example, when the electronic device 100 displays a part of the characters of the character set a, the remote control device 200 may receive a character switching input, and display another part of the characters of the character set a. When the electronic device 100 displays the last 1 character of the character set a, a character switching input may be received to display the characters of the character set B. The character type of the characters in the character set a is different from the character type of the characters in the character set B, for example, the characters in the character set a are pinyin characters and the characters in the character set B are english characters.

The above embodiments are merely for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
