Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a method for preventing screen touch error according to an exemplary embodiment, where the method for preventing screen touch error is applied to a mobile terminal, as shown in fig. 1, and includes the following steps.
In step S101, the mobile terminal detects a terminal screen of the mobile terminal.
In step S102, when detecting that the number of touch points exceeds the preset number of large-area touch operations, the mobile terminal obtains a first semaphore of a plurality of touch points corresponding to the large-area touch operations.
In step S103, the mobile terminal reduces a first preset threshold corresponding to the screen false touch prevention semaphore to a second preset threshold.
In step S104, the mobile terminal performs a false touch prevention process on the large-area touch operation according to the second preset threshold and the first semaphore of the touch point.
Due to the adoption of the method for preventing the screen from mistakenly touching, the touch points of the large-area touch operation of the terminal screen are judged, the preset threshold value is dynamically adjusted to inhibit the large-area mistaken touching operation, the accuracy of the touch operation is ensured, and the user experience is improved.
Fig. 2 is a flowchart illustrating another method for preventing screen touch error according to an exemplary embodiment, where the method for preventing screen touch error is applied to a mobile terminal, as shown in fig. 2, and includes the following steps.
In step S201, the mobile terminal detects a terminal screen of the mobile terminal.
When a user operates the mobile terminal, the user can perform touch operation on a terminal screen of the mobile terminal to trigger the mobile terminal to execute a touch instruction corresponding to the touch operation. The touch operations may be divided into click operations, sliding operations, pressing operations, and the like, and the number of touch points received by the mobile terminal is different for different operations. For example, a click operation corresponds to one touch point, a slide operation corresponds to a plurality of consecutive touch points, and a press operation corresponds to one touch point. The mobile terminal detects a terminal screen in real time or at intervals of preset time, and when touch operation is detected, the number of touch points of the touch operation is acquired. When the number of touch points of the touch operation detected by the mobile terminal exceeds a preset number, determining that the touch operation is a large-area touch operation, and executing step S202; when the number of the touch points of the touch operation detected by the mobile terminal does not exceed the preset number, determining that the touch operation is a non-large-area touch operation, and executing a touch instruction corresponding to the touch operation.
The mobile terminal may be any device with a touch screen, for example, the mobile terminal may be a mobile phone, a tablet computer, an intelligent home device with a touch screen, or an intelligent wearable device, and the mobile terminal is not particularly limited in this disclosure.
In step S202, when it is detected that the number of touch points exceeds the preset number of large-area touch operations, the mobile terminal obtains a first semaphore of a plurality of touch points corresponding to the large-area touch operations.
When the mobile terminal detects that a plurality of touch points exceeding a preset number are touched at the same time, it is determined that a large-area touch operation is received. The large-area touch operation may be a normal touch operation, for example, when a user has a wider finger and performs a pressing and dragging operation, a dragging distance is short, so that the mobile phone detects that a plurality of touch points exceeding a preset number are simultaneously touched on a mobile phone screen, and at this time, the mobile terminal determines that the large-area touch operation is received; the large-area touch operation may also be a large-area touch operation accompanied by a false touch operation during normal operation, for example, when a single-hand is used to operate a mobile phone, a finger performs a normal click operation, and a palm or other body part simultaneously touches a mobile phone screen, so that the mobile phone detects that a plurality of touch points exceeding a preset number are simultaneously touched on the mobile phone screen, and the mobile terminal determines that the large-area touch operation is received; the large-area touch operation may also be a false touch operation, for example, when the tablet computer plays a video, the palm or other part of the body contacts with the screen of the tablet computer, which results in the tablet computer detecting that a plurality of touch points exceeding a preset number are simultaneously touched on the screen of the tablet computer.
In the above situations, the mobile terminal determines that a large-area touch operation is received, but the large-area touch operation is likely to include a normal touch operation, so that further determination of the large-area touch operation is required. It should be noted that the actual touch operation condition that the mobile terminal determines that the large-area touch operation is received is complex, and this disclosure embodiment only lists possible conditions, and may enable the mobile terminal to determine that the touch operation of the large-area touch operation is received, and this disclosure embodiment is not limited specifically.
After determining that the large-area touch operation is received, the mobile terminal acquires first semaphore of a plurality of touch points corresponding to the large-area touch operation. In one implementation, the first semaphore can directly obtain the actual semaphore of the touch point, and for each touch point, the actual semaphore of the touch point is obtained as the first semaphore of the touch point. In another implementation, the first signal quantity needs to be obtained through calculation, the mobile terminal obtains second signal quantities of the multiple touch points, where the second signal quantities are actual signal quantity values of the multiple touch points, and the value of each second signal quantity of the multiple touch points is respectively subtracted from the reference signal quantity to obtain the first signal quantity of the multiple touch points.
It should be noted that, after the step S204 is executed, the step S204 may be directly executed, or the step S203 may be executed before the step S204 is executed, so as to determine whether the large-area touch operation is a large-area edge touch operation.
In step S203, the mobile terminal determines whether the large-area touch operation is a large-area edge touch operation according to the touch positions of the touch points, and if the large-area touch operation is the large-area edge touch operation, step S204 is executed.
After obtaining a plurality of touch points corresponding to the large-area touch operation, the mobile terminal obtains touch positions corresponding to the touch points, judges whether the large-area touch operation occurs in an edge area of a terminal screen of the mobile terminal according to the touch positions corresponding to the touch points, determines that the large-area touch operation is the large-area edge touch operation when the large-area touch operation occurs in the edge area of the terminal screen of the mobile terminal, and executes step S204; and when the large-area touch operation occurs in a non-edge area of a terminal screen of the mobile terminal, determining the large-area touch operation as the non-large-area edge touch operation.
When the mobile terminal determines that the large-area touch operation is a non-large-area edge touch operation, the mobile terminal performs a false touch prevention process on the large-area touch operation according to the first preset threshold and the first semaphore of the plurality of touch points, and determines whether the large-area touch operation is a false touch operation. For example, when there is no touch point with the first signal amount greater than the first preset threshold among the touch points, referring to fig. 3, the first preset threshold is 30, the first signal amounts of the touch points are respectively 0, 10, 15, 25, 20, and 5, that is, the first signal amount of the touch points does not reach the touch threshold, the mobile terminal ignores the touch operation of the touch points, and continues to execute step S201; when only one touch point with the first signal quantity greater than the first preset threshold exists in the touch points, referring to fig. 4, the first preset threshold is 30, the first signal quantity values of the touch points are respectively 0, 20, 25, 35, 20 and 5, then the only stored point is a normal touch point, and the mobile terminal executes the touch operation of the normal touch point according to the touch instruction corresponding to the normal touch point; when at least two touch points with the first semaphore larger than a first preset threshold exist in the touch points, whether the at least two touch points are continuous or not is judged. When the at least two touch points are continuous, referring to fig. 5, the first signal magnitude values of the touch points are respectively 0, 20, 30, 35, 20 and 5, the first signal magnitude values are continuous at two points of 30 and 35, the mobile terminal determines that the large-area touch operation corresponding to the touch points is large-area false touch operation, performs false touch prevention processing on the large-area touch operation, suppresses the touch points, and does not execute the touch instruction corresponding to the touch terminals; when the at least two touch points are not continuous, referring to fig. 6, the first signal magnitudes of the multiple touch points are respectively 0, 35, 15, 32, 10, and 5, and the continuous points of the first signal magnitudes of 32 and 35 are not continuous, and the mobile terminal determines that the large-area touch operation corresponding to the multiple touch points is a multi-point touch operation, that is, the mobile terminal performs operations on multiple areas, such as a two-finger or three-finger touch operation, at the same time.
In step S204, the mobile terminal reduces the first preset threshold corresponding to the screen false touch prevention semaphore to a second preset threshold.
Before the mobile terminal reduces a first preset threshold corresponding to the screen false touch prevention semaphore to a second preset threshold, the mobile terminal determines whether at least two touch points with the first semaphore larger than the first preset threshold exist in the touch points according to the first semaphore of the touch points. When at least two touch points which are larger than a first preset threshold exist in the plurality of touch points, determining whether the at least two touch points are continuous. When the at least two touch points are discontinuous, the first preset threshold corresponding to the screen false touch prevention semaphore is reduced to a second preset threshold.
For example, when there is no touch point with the first signal amount greater than the first preset threshold among the touch points, referring to fig. 3, the first preset threshold is 30, the first signal amounts of the touch points are respectively 0, 10, 15, 25, 20, and 5, that is, the first signal amount of the touch points does not reach the touch threshold, the mobile terminal determines that the touch operation is an erroneous operation, ignores the touch operation of the touch points, and continues to perform step S201. When only one touch point with the first signal quantity greater than the first preset threshold exists in the touch points, referring to fig. 4, the first preset threshold is 30, the first signal quantity values of the touch points are respectively 0, 20, 25, 35, 20 and 5, then the point with the first signal quantity value of 35 that exists only is a normal touch point, and the mobile terminal executes the touch operation of the normal touch point according to the touch instruction corresponding to the normal touch point; when at least two touch points with the first semaphore larger than a first preset threshold exist in the plurality of touch points, whether the at least two touch points are continuous or not is judged. When the at least two touch points are continuous, referring to fig. 5, the first signal magnitude values of the multiple touch points are 0, 20, 30, 35, 20, and 5, respectively, the two points of the first signal magnitude values 30 and 35 are continuous, the mobile terminal determines that the large-area touch operation corresponding to the multiple touch points is a large-area false touch operation, performs false touch prevention processing on the large-area touch operation, and suppresses the multiple touch points without executing the touch instructions corresponding to the multiple touch points; when the at least two touch points are discontinuous, referring to fig. 6, the first signal magnitudes of the multiple touch points are respectively 0, 35, 15, 32, 10, and 5, the continuous points where the first signal magnitudes are 32 and 35 are discontinuous, the mobile terminal reduces the threshold of the false touch prevention signal from the first preset threshold to a second preset threshold, and the second preset threshold is greater than the reference signal magnitude of the system.
In step S205, the mobile terminal performs a false touch prevention process on the large-area touch operation according to the second preset threshold and the first semaphore of the touch point.
The mobile terminal reduces the threshold value of the false touch prevention signal from a first preset threshold value to a second preset threshold value, and then compares the first semaphore with the second preset threshold value. For example, when there are at least two touch points of which the first semaphore is greater than the second preset threshold value among the plurality of touch points, whether the at least two touch points are continuous is determined. When the at least two touch points are continuous, referring to fig. 7, the first signal magnitudes of the touch points are 0, 35, 15, 32, 10, and 5, respectively, the mobile terminal determines that the large-area touch operation corresponding to the touch points is a large-area false touch operation, performs false touch prevention processing on the large-area touch operation, and suppresses the touch points without executing the touch instruction corresponding to the touch terminals; when the at least two touch points are not continuous, referring to fig. 8, the first signal magnitudes of the multiple touch points are respectively 0, 35, 5, 32, 10, and 5, the continuous points of the first signal magnitudes of 32 and 35 are not continuous, and the mobile terminal determines that the large-area touch operation corresponding to the multiple touch points is a multi-point touch operation, that is, the mobile terminal performs operations on multiple areas, such as a two-finger or three-finger touch operation, at the same time.
The detection range of the adjusted false touch prevention signal is correspondingly enlarged, the false touch prevention operation is more sensitive, and the false touch signal which cannot be inhibited by the first preset threshold can be inhibited.
Due to the adoption of the method for preventing the screen from mistakenly touching, the touch points of the large-area touch operation of the terminal screen are judged, the preset threshold value is dynamically adjusted to inhibit the large-area mistaken touching operation, and the accuracy of the touch operation is ensured.
