All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a specific implementation, the control terminal and the controlled terminal described in the embodiment of the present invention may include: smart phones, tablet computers, and the like, which are merely examples and are not exhaustive, and include but are not limited to the above terminals.
The following describes the text operation method and the terminal provided by the embodiment of the invention in detail with reference to fig. 1 to 4.
Fig. 1 is a flowchart illustrating a text operation method according to a first embodiment of the present invention. The character operation method of the embodiment of the invention comprises the following steps:
s100, acquiring click area information when the click operation of a user in a character editing area is detected;
in the embodiment of the invention, in the touch control type terminal, a large number of applications such as notes, short messages, various office application software, instant messaging application software and the like can provide a character editing interface for a user to carry out character editing operation. The text editing interface generally includes a function area and a text editing area, wherein the function area is used for providing various function buttons related to applications or texts for a user, such as new creation, saving, text color setting, font setting and the like. The text editing area is used for displaying texts for a user to perform text editing operation. In the text editing area, when the clicking operation of a user in the text editing area is detected, the clicking area information corresponding to the clicking operation is obtained. It should be noted that the click area information includes, but is not limited to, the size of the finger, the pressing pressure, and the shape of the click area.
S101, determining a target position coordinate corresponding to the click area according to the click area information;
in the embodiment of the present invention, since the characters displayed on the touch terminal are generally small, and the click area of the finger of the user is large compared with the characters and the distance between the characters, the target position coordinate corresponding to the click area needs to be determined according to the click area information corresponding to the click operation of the user. It should be noted that the target position coordinates include, but are not limited to, center coordinates of the click area or centroid coordinates of the click area. Specifically, optionally, the center coordinate of the clicked area may be determined according to the shape information of the clicked area, and the centroid coordinate of the clicked area may be determined according to the pressure information of the clicked area.
S102, acquiring target characters associated with the target position coordinates;
in the embodiment of the present invention, after the target position coordinate of the click area is determined, the target character associated with the target position coordinate may be determined according to the position coordinate, and the specific determination method may be to determine the character closest to the target position coordinate as the target character associated with the target position coordinate, preferably, compare the distance between the center point of each character and the target position coordinate, and then select the character with the smallest distance to determine the character as the target character.
S103, judging whether the target position coordinate is in a central area of the target character, wherein the central area is an area within a preset distance range from the central point of the target character;
in the embodiment of the invention, because the characters of the touch terminal are generally smaller, and the character space, the line spacing and the like are smaller compared with the fingers of a user or a click area, the user can hardly accurately position the center of the click area between the two characters and cannot fall on the characters. Therefore, in the embodiment of the present invention, the position relationship between the center point (i.e., the target position coordinate) of the click region and the displayed target text is divided into two types, one type is that the center point (the target position coordinate) of the click region falls within the center area of the target text, and the other type is that the center point (the target position coordinate) of the click region falls outside the center area of the text.
The central area is an area within a preset distance range from the central point of the target text, for example, if the length from the central point of the displayed target text to the edge of the target text is X, the area from the central point of the target text to the edge of the target text may be taken as the central area of the target text (for example, in practical applications, the proportion of the central area in the text may be automatically adjusted according to the user operation experience).
And S104, if yes, determining the clicking operation as the selection operation of the target characters.
In the embodiment of the invention, if the target position coordinate is in the central area of the target character, the click operation is determined as the selection operation of the target character, and the target character is displayed in a distinguishing way. The distinguishing display mode can make the user know which character is in the selected state more intuitively, and the distinguishing display can be that a box is displayed at the edge of the selected target character, an underline is displayed below the target character, or the target character is displayed in different colors. Preferably, the distinguishing display may further include displaying a draggable identifier on the target text in the selected state, and the user may drag the draggable identifier to increase the number of texts in the selected state. After the characters are in the selected state, the user can delete, change colors, move and the like on the characters.
According to the method and the device for processing the character editing area, when the clicking operation of a user in the character editing area is detected, the information of the clicking area is obtained, the target position coordinate corresponding to the clicking area is determined according to the information of the clicking area, the target character related to the target position coordinate is obtained, whether the target position coordinate is located in the central area of the target character or not is judged, and if the target position coordinate is located in the central area of the target character, the clicking operation is determined as the selection operation of the target character. The method can realize the selection of the target characters according to the click operation of the user, and is convenient to operate.
Fig. 2 is a flowchart illustrating a text operation method according to a second embodiment of the present invention. The character operation method of the embodiment of the invention comprises the following steps:

In the embodiment of the invention, when the dragging operation of the dragging identifier is detected, the characters passed by the sliding track are set to be in a selected state. In one embodiment, when the existing text is in the selected state before the selection, the selected state of the originally selected text is cancelled. In another embodiment, when the existing characters before the selection are in the selected state, the selected state of the originally selected characters is not cancelled.
S207, displaying an operation menu on the characters in the selected state, wherein the operation menu comprises a plurality of options, and the options are used for indicating character editing operation corresponding to the options;
in the embodiment of the invention, the user can delete, change the color, move and the like on the characters in the selected state. In order to be able to explicitly instruct the user's operation, an operation menu is displayed on the text in the selected state, the operation menu including a plurality of options each for instructing a corresponding text editing operation. For example, the options may include delete, change color, copy, and move, among others.
S208, when it is detected that the user selects the target option from the multiple options, performing a text editing operation corresponding to the target option on the text in the selected state.
In the embodiment of the invention, when the user is detected to select the target option from the multiple options, the text editing operation corresponding to the target option is performed on the text in the selected state. For example, when the user operates a deletion option in the operation menu, the text in the selected state is deleted.
S209, if the target position coordinate is not located in the central area of the target character, determining the click operation as an operation of inserting a cursor between the target character and other characters.
In the embodiment of the invention, if the target position coordinate is not in the central area of the target character, the target character is not selected, a cursor is inserted between the target character and the corresponding other characters, and after the cursor is inserted, the user can input or delete the cursor.
According to the method and the device for processing the character editing area, when the clicking operation of a user in the character editing area is detected, the information of the clicking area is obtained, the target position coordinate corresponding to the clicking area is determined according to the information of the clicking area, the target character related to the target position coordinate is obtained, whether the target position coordinate is located in the central area of the target character or not is judged, and if the target position coordinate is located in the central area of the target character, the clicking operation is determined as the selection operation of the target character.
