Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a method for preventing a false touch according to an embodiment of the present invention, where the method is applicable to a situation where a mobile terminal is held with a single hand to perform false touch operation identification, and the method may be executed by the mobile terminal having a touch screen, where the mobile terminal may be a smart phone, a tablet computer, or the like, as shown in fig. 1, the method for preventing a false touch specifically includes the following steps:

and 110, if at least two touch operations are detected within a preset time length, acquiring the positions of the at least two touch operations.

The preset time length is used for representing the time interval of the correct operation and the misoperation input by the user. The preset time period may be 0 second, that is, at least two touch operations are detected simultaneously. The preset time period may also be an empirical value, such as 0.1-0.7 seconds, preferably 0.3 seconds. The empirical value may be a time interval derived by a programmer from a limited number of experiments or may be a time interval set by a user.

The touch operation may be a click operation or a slide operation, where the click operation includes a single click operation and a continuous click operation (e.g., a double click operation). Preferably, the touch operation is a click operation. And if the touch operation is a click operation, taking the screen coordinate corresponding to the click operation as the position of the touch operation. And if the touch operation is the sliding operation, taking the starting point and the end point of the sliding track corresponding to the sliding operation 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. Illustratively, 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 serial number	Position (coordinate)
		Touch operation A	(100,300)
Touch operation B	(620,1000)

And 120, if the positions of the at least two touch operations are respectively located in at least two preset detection areas, acquiring a left-right hand holding state.

Optionally, the preset detection area may be a detection area corresponding to a plurality of edges of the screen, and the detection area corresponding to each edge does not have an overlapping area. In the above example, the preset detection area may be detection areas corresponding to four edges of the screen, as shown in fig. 2, a detection area a corresponding to an upper edge of the screen is an area determined by four points (0,0), (720,0), (720,150), and (0,150), and a detection area b corresponding to a lower edge of the screen is an area determined by four points (0,1130), (720,1130), (720,1280), and (0,1280); the detection area c corresponding to the left edge of the screen is an area determined by four points (0,150), (150 ), (150,1130) and (0,1130); the detection area d corresponding to the right edge of the screen is an area determined by four points (570,150), (720,150), (720,1130) and (720,1130). 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, and 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 that the left-right hand holding state is acquired.

The left and right hand holding states can be obtained by a gravitational acceleration sensor. For example, the gravitational acceleration sensor may determine the left-right hand holding state according to the current inclination angle of the mobile terminal. Optionally, the gravity acceleration sensor may determine the left-right hand holding state according to the instantaneous rotation angle of the mobile terminal. For example, when the user uses a right hand and a single hand to perform single-hand operation, the mobile terminal rotates along the lower right direction along with the action of clicking by the thumb when the thumb of the right hand clicks the screen, and the gravitational acceleration sensor in the mobile terminal judges that the mobile terminal is in the right hand holding state at the moment according to the sensed motion direction of the mobile terminal.

And step 130, responding at least one touch operation matched with the left-right hand holding state.

When a user holds the mobile terminal with one hand, the thenar of the palm is easy to generate false touch, so when a plurality of touch operations exist in the screen, the touch operation far away from the side of the holding hand is determined as the touch operation matched with the left-right holding state.

Illustratively, when the preset detection areas are positioned at two sides of the screen, if the preset detection areas are in a left-hand holding state, the touch operation at the right side of the screen is responded; and if the screen is in the right-hand holding state, responding to the touch operation on the left side of the screen.

The method includes the steps that firstly, when at least two touch operations are detected within a preset time length, the positions of the at least two touch operations are obtained; then, when the positions of at least two touch operations are respectively located in at least two preset detection areas, a left-hand holding state and a right-hand holding state are obtained; and finally, responding at least one touch operation matched with the left-right hand holding state. In the prior art, whether misoperation occurs or not is determined according to the area of the touch surface, however, the detection method cannot identify the non-touch with small area, the false touch identification efficiency is low, the area calculation is needed for calculating the area of the touch surface, the consumed time is long, and the power consumption of the false touch identification operation is increased. In the embodiment, the mistaken touch operation can be identified only by comparing whether touch operations exist in different areas, so that the operation is simple and convenient, the identification efficiency is high, and the electric quantity is saved. Meanwhile, the mistaken touch operation with a small contact area can be identified, and the accuracy of mistaken touch identification is improved.

Further, fig. 3 is a flowchart of a method for preventing false touch according to an embodiment of the present invention, and as shown in fig. 4, the preset detection area includes a left screen and a right screen. The left screen is a screen area on the left side of the central axis of the screen, and the right screen is a screen area on the right side of the central axis of the screen. Step 120, if the positions of the at least two touch operations are respectively located in the at least two preset detection areas, acquiring a left-right hand holding state, and implementing the following steps:

and 120a, if the positions of at least two touch operations are respectively positioned on the left screen and the right screen, acquiring the holding states of the left hand and the right hand.

And if the left screen and the right screen respectively contain at least one touch operation, acquiring the holding state of the left hand and the right hand.

If the start point coordinate and the end point coordinate of the slide operation are located in the same side screen, the side screen contains the slide operation. If the start point and the end point of the slide operation are located in the left screen and the right screen, respectively, neither the left screen nor the right screen contains the slide operation.

Accordingly, the step 130, responding to at least one touch operation matched with the left-right hand holding state, may be implemented as:

and step 130a, if the left-right hand holding state is the left-hand holding state, responding to the touch operation in the right screen.

The touch operation in the right screen is a touch operation matching the left-hand grip state. And shielding the touch operation detected in the left screen and responding to the touch operation detected in the right screen.

The touch operation in the right screen may be one or more. And if the operation is a touch operation, responding to the touch operation. If the touch operation is a plurality of (at least two) touch operations, a valid touch operation is determined from the plurality of touch operations.

And step 130b, responding to the touch operation in the left screen if the left-right hand holding state is the right hand holding state.

The touch operation in the left screen is a touch operation matching the right hand-held grip state. And shielding the touch operation detected in the right screen and responding to the touch operation detected in the left screen. The touch operation in the left screen may be one or more.

The touch operation response method and the touch operation response device can determine the touch operation response according to the number of the touch operations detected in the left screen and the right screen, reduce the complexity of false touch recognition, and are simple and easy to use.

Further, fig. 5 is a flowchart of a method for preventing a false touch according to an embodiment of the present invention, where when a plurality of touch operations matching with the left-hand holding state and the right-hand holding state are performed, step 130 is performed in response to at least one touch operation matching with the left-hand holding state and the right-hand holding state, and may be implemented in the following manner:

step 131, if a plurality of touch points are detected in a preset detection area, determining effective touch points according to touch surface areas corresponding to the plurality of touch points.

And acquiring a preset area corresponding to the finger. And if the touch operations are click operations, determining a touch point with the contact area close to the preset area as an effective touch point. Optionally, the preset area is 30 × 30 pixels to 50 × 50 pixels, preferably 44 × 44 pixels. And if the touch operations are all sliding operations, determining the validity of the sliding operations according to the operation objects of the sliding operations, and determining the touch points corresponding to the valid sliding operations as valid touch points. And if the plurality of touch operations comprise click operations and touch operations, selecting one effective operation from the click operations and the touch operations respectively.

Step 132, responding to the valid touch points.

This implementation can select effectual touch point from a plurality of touch operation and respond, avoids responding invalid touch point, and then improves the reliability of the touch point of response, further practices thrift power consumption.

Further, fig. 6 is a flowchart of a method for preventing a false touch according to an embodiment of the present invention, as a further description of the foregoing embodiment, in step 110, the detecting at least two touch operations within a preset time period may be implemented as:

and step 111, if the first touch operation is detected at the first moment, starting timing.

The first touch operation is the first touch operation received after the response of the previous touch operation. When a user clicks the screen by using a thumb, the thenar of the palm firstly contacts the screen due to the motion track of the thumb, the belly of the thumb contacts the screen afterwards, and the touch time difference between the thenar and the screen is small, such as less than 0.3 second. In the above example, when the first touch operation triggered on the screen is detected, the time is counted by a timer.

And 112, when the timing result reaches the preset touch interval duration, stopping timing and acquiring the touch operation detected from the first time to the timing stop time.

The preset touch interval duration may be 0.1 second to 1.0 second, and preferably, 0.3 second. And during timing, continuously detecting touch operations triggered on the screen, and counting coordinates corresponding to each touch operation to obtain a touch position of the touch operation.

This embodiment can be when triggering touch operation on the screen, discerns the touch operation in the screen after the length of time of touch interval is predetermine, further improves the discernment of mistake touch operation, avoids simultaneously slightly being earlier than correct operation triggering because of the mistake touch operation, leads to the mistake to carry out mistake touch operation, improves the recognition efficiency of mistake touch operation.
