Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flowchart of a method for preventing accidental touches provided by Embodiment 1 of the present invention. This embodiment can be applied to the case of identifying accidental touch operations when a mobile terminal is held with one hand. This method can be implemented by a mobile terminal with a touch screen. Execution, the mobile terminal may be a smart phone, a tablet computer, etc. As shown in FIG. 1 , the method for preventing accidental touch specifically includes the following steps:

Step 110: If at least two touch operations are detected within a preset time period, acquire the positions of the at least two touch operations.

The preset duration is used to indicate the time interval between correct operations and incorrect operations of user input. The preset duration can be 0 seconds, that is, at least two touch operations are detected at the same time. The preset duration may also be an empirical value, such as 0.1-0.7 seconds, preferably 0.3 seconds. The empirical value can be a time interval obtained by the programmer based on a limited number of trials, or it can be a time interval set by the user.

The touch operation can be a click operation or a slide operation, wherein the click operation includes a single click operation and a double click operation (such as a double click operation). Preferably, the touch operation is a click operation. If the touch operation is a click operation, the screen coordinates corresponding to the click operation are taken as the position of the touch operation. If the touch operation is a sliding operation, the start and end points of the sliding track corresponding to the sliding operation are used as the position of the touch operation.

The position information of all the acquired touch operations can be stored through the temporary touch position information list. Optionally, the acquired position information of all touch operations may also be stored in the form of a queue, a stack, or a linked list. Exemplarily, the screen resolution is 720*1280, the temporary touch position information list is shown in Table 1, and the two acquired touch operations are touch operation A and touch operation B. The position of touch operation A is (100, 300), and the position of touch operation B is (620, 1000).

Table 1

Touch operation number Position coordinates) touch operation A (100,300) touch operation B (620,1000)

Step 120: If the positions of the at least two touch operations are located in the at least two preset detection areas, respectively, acquire the holding state of the left and right hands.

Optionally, the preset detection areas may be detection areas corresponding to multiple edges of the screen, and the detection areas corresponding to each edge do not have overlapping areas. In the above example, the preset detection area can be the detection area corresponding to the four edges of the screen. As shown in Figure 2, the detection area a corresponding to the upper edge of the screen is (0,0), (720,0), (720,150 ), (0,150) the area determined by four points, the detection area b corresponding to the lower edge of the screen is the area determined by (0,1130), (720,1130), (720,1280), (0,1280) four points ; The detection area c corresponding to the left edge of the screen is the area determined by four points (0,150), (150,150), (150,1130), (0,1130); the detection area d corresponding to the right edge of the screen is (570,150) , (720,150), (720,1130), (720,1130) The area determined by the four points. In the above example, the touch operation A is located in the detection area a, and the touch operation B is located in the detection area b. At this time, the positions of the two touch operations (touch operation A and touch operation B) are located in two different detection areas respectively. , so get the left and right hand holding state.

The holding state of the left and right hands can be obtained through the gravitational acceleration sensor. Exemplarily, the gravitational acceleration sensor may determine the holding state of the left and right hands according to the current tilt angle of the mobile terminal. Optionally, the gravitational acceleration sensor may determine the holding state of the left and right hands according to the instantaneous rotation angle of the mobile terminal. For example, when the user uses the right hand to perform one-handed operation, when the right thumb clicks on the screen, the mobile terminal will rotate along the bottom right along with the click of the thumb, and the gravitational acceleration sensor in the mobile terminal will , and then it is judged that the mobile terminal is in the right-hand holding state at this time.

Step 130: Respond to at least one touch operation matching the holding state of the left and right hands.

When the user holds the mobile terminal with one hand, the thenar part of the palm is prone to mistouch. Therefore, when there are multiple touch operations on the screen, the touch operation on the side away from the handshake is determined as the touch operation that matches the holding state of the left and right hands. .

Exemplarily, when the preset detection area is located on both sides of the screen, if it is in a left-hand holding state, it responds to a touch operation on the right side of the screen; if it is a right-hand holding state, it responds to a touch operation on the left side of the screen.

In this embodiment, when at least two touch operations are detected within a preset period of time, the positions of the at least two touch operations are acquired; then, when the positions of the at least two touch operations are respectively located in at least two preset detection areas, the positions of the at least two touch operations are acquired Left and right hand holding states; finally, responding to at least one touch operation matching the left and right hand holding states. The prior art determines whether it is a misoperation based on the area of the touch surface. However, this detection method cannot identify a small area without touch, and the efficiency of mistouch recognition is low. In addition, calculating the area of the touch surface requires area calculation, which takes a long time. to increase the power consumption of the false touch recognition operation. In this embodiment, the false touch operation can be identified only by comparing whether there is a touch operation in different areas, the operation is simple, the identification efficiency is high, and the power is saved. At the same time, the false touch operation with a small contact area can be recognized, and the accuracy of false touch recognition is improved.

Further, FIG. 3 is a flowchart of a method for preventing accidental touch provided by Embodiment 1 of the present invention. As a further description of the above steps, as shown in FIG. 4 , the preset detection area includes a left screen and a right screen. side screen. The left screen is the screen area on the left side of the screen axis, and the right screen is the screen area on the right side of the screen axis. Step 120: If the positions of the at least two touch operations are located in the at least two preset detection areas, respectively, obtain the holding state of the left and right hands, which can be implemented in the following manner:

Step 120a: If the positions of the at least two touch operations are located on the left screen and the right screen, respectively, acquire the holding state of the left and right hands.

If the left screen and the right screen respectively contain at least one touch operation, obtain the holding state of the left and right hands.

If the start and end coordinates of the swipe operation are in the same side screen, the side screen contains the swipe operation. If the swipe starts and ends in the left and right screens, then neither the left nor the right screen contains the swipe.

Correspondingly, step 130, responding to at least one touch operation matching the holding state of the left and right hands, may be implemented as:

Step 130a: If the left-hand holding state is the left-hand holding state, respond to the touch operation on the right screen.

The touch operation in the right screen is a touch operation that matches the holding state of the left hand. Blocks touches detected in the left screen and responds to touches detected in the right screen.

The touch actions in the right screen can be one or more. If it is a touch operation, respond to the touch operation. If there are multiple (at least two) touch operations, a valid touch operation is determined from the multiple touch operations.

Step 130b, if the holding state of the left and right hands is the holding state of the right hand, respond to the touch operation on the left screen.

The touch operation in the left screen is a touch operation that matches the holding state of the right hand. Blocks touches detected in the screen on the right and responds to touches detected in the screen on the left. The touch actions in the left screen can be one or more.

This embodiment can determine the responsive touch operations according to the number of touch operations detected in the left screen and the right screen, thereby reducing the complexity of false touch recognition, and being simple and easy to use.

Further, FIG. 5 is a flowchart of a method for preventing accidental touches provided by Embodiment 1 of the present invention. When there are multiple touch operations matching the holding states of the left and right hands, step 130 is to respond to the touch operations matching the holding states of the left and right hands. At least one touch operation, which can be implemented in the following ways:

Step 131: If multiple touch points are detected in a preset detection area, determine the effective touch points according to the touch surface area corresponding to the multiple touch points.

Get the preset area corresponding to the finger. If the multiple touch operations are all click operations, a touch point whose contact area is close to the preset area is determined as an effective touch point. Optionally, the preset area is 30*30 pixels to 50*50 pixels, preferably, 44*44 pixels. If the multiple touch operations are sliding operations, the validity of the sliding operation is determined according to the operation object of the sliding operation, and the touch point corresponding to the valid sliding operation is determined as the valid touch point. If the multiple touch operations include a click operation and a touch operation, select an effective operation from the click operation and the touch operation respectively.

Step 132, responding to the valid touch point.

This implementation can select valid touch points from multiple touch operations to respond, avoid responding to invalid touch points, thereby improving the reliability of the responding touch points and further saving power consumption.

Further, FIG. 6 is a flowchart of a method for preventing false touches provided by Embodiment 1 of the present invention. As a further description of the above embodiment, in step 110, at least two touch operations are detected within a preset time period, Can be implemented as:

Step 111: If the first touch operation is detected at the first moment, start timing.

The first touch operation is the first touch operation received after the response to the previous touch operation. When the user taps the screen with the thumb, the thenar of the palm will first contact the screen due to the motion trajectory of the thumb, and the belly of the thumb will contact the screen later, and the touch time difference between the two is small, for example, less than 0.3 seconds. In the above example, when the first touch operation on the screen is detected, it is timed by a timer.

Step 112 , when the timing result reaches the preset touch interval duration, stop timing and acquire touch operations detected from the first moment to the timing stop time.

The preset touch interval duration may be 0.1 seconds to 1.0 seconds, preferably, 0.3 seconds. During the timing period, the touch operation triggered on the screen is continuously detected, the coordinates corresponding to each touch operation are counted, and the touch position of the touch operation is obtained.

In this embodiment, when a touch operation is triggered on the screen, the touch operation on the screen can be identified after a preset touch interval, so as to further improve the recognition of the false touch operation, and at the same time avoid the false touch operation being triggered slightly earlier than the correct operation, resulting in The false touch operation is performed incorrectly, and the recognition efficiency of the false touch operation is improved.

Step 200: Configure the left screen as one detection area, and configure the right screen as another detection area.

Step 210: If the first touch operation is detected in any detection area at the first moment, start timing.

Step 220: When the timing result reaches the preset touch interval duration, stop timing and acquire touch operations detected between the first moment and the timing stop moment.

Step 230: If N (N is greater than or equal to 2) touch operations are detected, acquire the positions of the N touch operations.

Step 240: If the positions of at least two touch operations are located on the left screen and the right screen, respectively, acquire the holding state of the left and right hands.

Step 250: If the left-hand holding state is the left-hand holding state, respond to the touch operation on the right screen.

Step 260: If the holding state of the left and right hands is the holding state of the right hand, respond to the touch operation on the left screen.

Step 270: If multiple touch points are detected on the right screen or the left screen of the response, determine the valid touch points according to the touch surface area corresponding to the multiple touch points.
