Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The first embodiment of the present application relates to a method for preventing false touch, and the core of the present embodiment is that the key frequency of the user is used as an index to determine whether to switch the use state of the touch area, so that the operation steps of the user are greatly simplified. Implementation details of the method for determining false touch according to the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment.
A schematic flow chart of a method for preventing false touch in this embodiment is shown in fig. 1, and referring to fig. 1, the method 100 for preventing false touch includes the following steps.
Step 101: and defining a false touch area in a touch area of the electronic equipment, wherein other parts except the false touch area in the touch area are normal areas. The purpose of this step is to pre-delineate the area that is prone to false touches, ready for subsequent decisions on false touches. The edge portion of the touchable area near the keyboard side is generally defined as a false touch area.
Fig. 2 to 4 show several embodiments of false touch area and normal area division.
Fig. 2 is a schematic diagram illustrating the division of the touch area applied to the notebook computer according to an embodiment of the application. Referring to fig. 2, the touchable area 210 is a rectangular area located under the keyboard area, and includes: a first edge 211 near the lower edge of the keyboard region, a second edge 212 opposite the first edge 211, and opposite third and fourth edges 213 and 214, respectively, on both sides. The touchable area 210 is divided into a false touch area 215 and a normal area 216, wherein the false touch area 215 is substantially C-shaped and is composed of edge portions near the first edge 211, the third edge 213 and the fourth edge 214.
Fig. 3 is a schematic diagram illustrating the division of a touch area applied to a notebook computer according to another embodiment of the application. Referring to fig. 3, the touchable area 220 is a rectangular area located under the keyboard area, which includes: a first side 221 near the lower edge of the keyboard region, a second side 222 opposite to the first side 221, and opposite third and fourth sides 223 and 224, respectively, on both sides. The touchable region 210 is divided into a false touch region 225 and a normal region 226, wherein the false touch region 225 has a shape substantially similar to that of the false touch region in fig. 2, except that two right angle regions inside the C-shape are each added with a triangular region to better accommodate the hand shape.
Fig. 4 is a schematic diagram illustrating the division of the touch area applied to a tablet computer or a mobile phone according to an embodiment of the application. Referring to fig. 4, the touchable area 230 is a rectangular area located above the keyboard area 310, which includes: a first side 231 near the upper edge of the keyboard region, a second side 232 opposite the first side 231, and opposite third and fourth sides 233 and 234, respectively, on both sides. The touchable area 230 is divided into a false touch area 235 and a normal area 236, wherein the false touch area 235 is substantially C-shaped and is composed of edge portions near the first side 231, the third side 233 and the fourth side 234.
Preferably, the method for preventing false touch further comprises the step of defining different false touch areas according to different use environments of the electronic device; the use environment of the electronic equipment comprises: desktop, laptop, and handheld. Because the relative positions of the hands of the user and the electronic equipment can be changed in different use environments, the corresponding false touch areas in each use environment can be different, and the best matched false touch areas can be set according to each use environment, so that the judgment accuracy can be further improved. In some embodiments, the use environment of the electronic device may be determined by detecting an inclination angle of the electronic device, which may be detected by a sensor such as a gyroscope provided inside the electronic device.
Alternatively, in other embodiments, the relative position between the user's hand and the electronic device may be detected directly by a position detector mounted on the electronic device, and the false touch region may then be defined based on the relative position.
Step 102: and monitoring and judging whether the key frequency of the user is larger than a preset frequency threshold value. The key frequency of the user can represent whether the user is in a continuous input state or not, because the key frequency of the user in the continuous input state is larger than the key frequency of the user in a discontinuous input state; thus, a threshold value can be set, namely: a frequency threshold, when the key frequency is greater than the frequency threshold, the user is indicated to be in a continuous input state at the moment. Otherwise, the user is indicated to be in a discontinuous input state at the moment. Wherein the frequency threshold may be set to the lowest key frequency value of the user in the continuous input state. Preferably, the frequency threshold may be in the range of 5-15 times/second, for example: 5 times/second. It should be noted that the above frequency threshold is merely an exemplary example provided for convenience of description, and the frequency threshold is not limited to the above values in practical use.
Step 103: and when the key frequency of the user is larger than the frequency threshold value, setting the touch area into an error touch prevention mode.
Step 104: and when the key frequency of the user is smaller than or equal to the frequency threshold value, setting the touch area into a normal mode.
In the anti-false touch mode, after receiving the touch signal of the user, the positional relationship between the touch area and the false touch area is determined, as shown in step 105. There may be three situations in the positional relationship between the touch area and the false touch area: firstly, the touch area is completely positioned in the false touch area; secondly, the touch area is completely positioned in the normal area; third, a part of the touch area is located in the false touch area, and the rest part is located in the normal area.
If the touch area is completely located outside the false touch area, namely: completely within the normal zone, step 106 is performed, namely: and judging that the touch is normal operation. Then, as shown in step 112, this touch is responded to.
If the touch area is completely within the false touch area, step 107 is performed, namely: and judging the touch is a false touch. Then, as shown in step 113, the position of the input cursor is kept unchanged to prevent the input from being affected by the false touch.
If a portion of the touch area is located in the false touch area and the rest is located in the normal area, step 108 is performed, namely: calculating the area of the touch area, and judging whether the area of the touch area is larger than a preset area threshold value; the area threshold is the maximum value of the contact area between the finger and the touch area under the condition of touching with the finger. Preferably, the area threshold is in the range of 23-29 square centimeters, for example: 25 square cm.
If the area of the touch area is equal to or smaller than the area threshold, which indicates that the user touches by a finger, step 109 is executed to determine that the user touches as a normal touch operation. Then, as shown in step 112, this touch is responded to.
If the area of the touch area is greater than the area threshold, which indicates that the user touches the palm, step 110 is executed to determine that the user touches the palm. Then, as shown in step 113, the position of the input cursor is kept unchanged to prevent the input from being affected by the false touch.
Preferably, the method for preventing false touch may further include updating and correcting the false touch area, so that the efficiency of determining false touch can be further improved. Specifically, as shown in step 111, a portion of the touch area outside the false touch area is defined as a portion of the false touch area.
In addition, the false touch area can be updated and corrected by detecting the correction action of the user. Referring to fig. 5, the method of preventing false touches may further comprise steps 114-115. In step 114, detecting a correction operation of the user, wherein the correction operation is specifically: and moving the input cursor back to the input position before the touch operation in a time period after the touch operation is finished, wherein the time period is 0.5-2 seconds. In step 115, a previous touch area of the corrective action is defined as a portion of the false touch area.
In an exemplary embodiment, the size of the false touch area is the same as that of the touchable area, i.e. all areas of the touchable area are false touch areas, and when the key frequency of the user is greater than the frequency threshold, the touchable area does not respond to the touch operation.
Compared with the prior art, the embodiment of the application realizes the automatic switching of the touch area between the normal use state and the error touch prevention state by monitoring and judging the key frequency of the user, thereby greatly simplifying the operation steps of the user. In addition, the embodiment of the application divides the touch area, only the touch action which is overlapped with the error touch area is judged as the error touch in the error touch prevention state, and the judgment accuracy is further improved.
