The disclosure provides a touch control method, which can be applied to a terminal, wherein the terminal is provided with a display screen with a touch control function, and the display screen can be a mobile phone, a tablet personal computer, a personal digital assistant and the like.
Fig. 1 is a flowchart of a touch control method according to an exemplary embodiment, where the touch control method shown in fig. 1 includes the following steps:
in step 101, under the condition that a sliding screen operation is detected, current touch point coordinates and historical touch point coordinates are obtained.
The terminal is internally provided with a processing system and a touch control chip, the touch control chip is used for detecting a touch control point on the touch control screen, after the touch control chip detects a touch control point, a preset algorithm is used for calculating coordinates of a reporting point corresponding to the touch control point, namely reporting point coordinates, the calculated reporting point coordinates are reported to the processing system, and the processing system responds to touch control operation according to the reporting point coordinates. For example, the processing system sends the reporting point coordinates to the active gaming application so that the gaming application responds based on the reporting point, such as drawing a sliding track, moving a game object, and so forth.
The current touch point is the touch point detected at the current moment, and in the process of sliding the screen, the current touch point is the touch point with the latest sliding screen operation at the current moment; the historical touch point is the touch point detected before the current moment in the (same) screen sliding process.
In step 102, the current displacement and the historical displacement of the slide operation are determined.
The current displacement is the displacement of the sliding screen operation in the current period. The historical touch point is a touch point detected before the current touch point, and the current displacement may be equal to a difference between the current touch point coordinates and the historical touch point coordinates. Preferably, the touch chip may acquire a previous reporting point coordinate adjacent to the current reporting point coordinate, and calculate a difference between the current touch point coordinate and the previous reporting point coordinate as the current displacement.
Or, the touch chip may acquire the previous touch point coordinate adjacent to the current touch point coordinate, and calculate the difference between the current touch point coordinate and the previous touch point coordinate as the current displacement.
The history displacement is the displacement of the sliding screen operation in the history period. The historical touch points are touch points detected at historical moments before the current moment, and the touch chip can acquire at least two adjacent historical touch point coordinates and acquire the difference value between every two adjacent historical touch point coordinates as historical displacement.
When the touch chip acquires two historical touch point coordinates, the historical displacement is equal to the difference value of the two historical touch point coordinates. When the touch chip acquires a plurality of historical touch point coordinates, acquiring difference values between every two adjacent historical touch point coordinates, and acquiring historical displacement based on the acquired plurality of difference values.
In step 103, the current touch point coordinates are corrected based on the current displacement, the historical displacement and the historical touch point coordinates, and the current reporting point coordinates are determined based on the correction result.
Under ideal conditions, in the screen sliding process, the coordinates of the touch points detected by the touch chip are the same as the coordinates of the reported reporting points, and the terminal can accurately respond to the screen sliding operation. However, in actual situations, based on the limitations of the algorithm and the system processing flow, the reported point coordinates are generally smaller than the detected touch point coordinates, so that the response position of the sliding operation is behind the touch point position.
In order to solve the problems, the method and the device use the current displacement, the historical displacement and the historical touch point coordinates to correct the current touch point coordinates, and determine the current reporting point coordinates based on the correction result, so that the current reporting point coordinates are closer to the current touch point coordinates, the degree of touch delay is reduced, and the touch experience of a user is improved.
Alternatively, the current reporting point coordinates may be calculated by the following formula:
M＝S n +S n-1 +……+S n-s formula (2)
Wherein X 'is' n The coordinates of the current reporting point are obtained; x is X n Sit for the current touch pointMarking; x is X n-s Is X n The former s-th historical touch point coordinate; s is S n Is the current displacement; s is S n-s Is X n Previous s-th historical touch point coordinates and X n Historical displacement between the previous (s+1) th historical touch point coordinates; s is a positive integer greater than or equal to 1.
Preferably, when the difference between the current touch point coordinate and the previous report point coordinate is taken as the current displacement, and s=2, the current report point coordinate may be calculated by the following formula:
M＝S n +S n-1 +S n-2 formula (4)
S n ＝X n -X′ n-1 Formula (5)
S n-1 ＝X n-1 -X n-2 Formula (6)
S n-2 ＝X n-2 -X n-3 Formula (7)
Wherein X 'is' n The coordinates of the current reporting point are obtained; x'. n-1 Reporting the point coordinates for the previous one; x is X n The current touch point coordinates; x is X n-1 Is X n The first previous historical touch point coordinates; x is X n-2 Is X n A first historical touch point coordinate; x is X n-3 Is X n The first third historical touch point coordinates.
In the above embodiment, s=2 is adopted, so that the reported point coordinate is ensured to be closer to the actual touch point coordinate, and the data processing efficiency is effectively improved.
In the process of accelerating the sliding screen, based on the sliding screen speed change, the sliding screen distances in the preset interval duration are different, and the method and the device directly adjust the weight value of the coordinates of the touch point according to the sliding screen speed indirectly and the sliding screen speed according to the preset interval duration, can reduce the response hysteresis quality of the touch operation, and reduce the response delay degree in the sliding screen process.
In the related art, a touch chip generally sets a fixed weight value to determine a current reporting point coordinate, for example, the current reporting point coordinate may be calculated by the following formula:
wherein X 'is' n The coordinates of the current reporting point are obtained; x is X n The current touch point coordinates; x is X n-1 Is X n The first previous historical touch point coordinates; x is X n-1 Is X n-2 The first second historical touch point coordinates.
Because the weight value of each touch point coordinate in the formula (8) is one third of a fixed value, the difference between the reported point coordinate reported to the processing system and the actual touch point coordinate is larger and larger in the process of accelerating screen sliding, and the accumulated delay is larger and larger, so that the chiral experience of a user is poorer and worse.
Since in formula (3) of the present disclosure, (X) n -X′ n-1 )>X n -X n-1 Always hold, so the current touch point coordinate X n The weight value of (2) is always more than one third in the process of sliding the screen at a constant speed and in the process of accelerating the screen. Using a larger weight value to X n The weight addition calculation is carried out, so that larger X 'can be obtained' n ，X′ n Will be closer to the actual X n The response position of the sliding screen operation is closer to the actual touch position.
Fig. 2 is a schematic diagram of a touch point shown according to an example embodiment. In FIG. 2, the solid origin represents the actual touch point, X 0 、X 1 、X 2 、X 3 、X 4 And X 5 The actual touch point coordinates are detected according to the equal interval duration. S is S 0 Is X 0 And X 1 A sliding distance therebetween; s is S 1 Is X 1 And X 2 A sliding distance therebetween; s is S 2 Is X 2 And X 3 A sliding distance therebetween; s is S 3 Is X 3 And X 4 A sliding distance therebetween; s is S 4 Is X 4 And X 5 Sliding distance between the two. The open origin represents the reporting point determined by using the formula (8), S ' represents the distance between two adjacent reporting points, and S ' is respectively ' 0 、S′ 1 、S′ 2 、S′ 3 、S′ 4 . Triangles represent reported points determined using equation (3), denoted as X ', X ' respectively ' 0 、X′ 1 、X′ 2 、X′ 3 、X′ 4 And X' 5 。
In fig. 2, for the actual touch point coordinates in the process of accelerating the screen, the report point coordinates calculated by using the formula (8) are later than the report point coordinates calculated by using the formula (3), and the report point coordinates calculated by using the formula (3) are closer to the actual touch point coordinates.
In step 104, the slide operation is responded to based on the current reporting point coordinates.
And the touch control chip sends the current reporting point coordinates to the processing system, and the processing system responds to the screen sliding operation according to the current reporting point coordinates. For example, the processing system sends the current reporting point coordinates to the active gaming application so that the gaming application responds based on the current reporting point coordinates, such as drawing a sliding track, moving a game object, and so forth.
In the embodiment of the disclosure, under the condition that the sliding screen operation is detected, correcting the current touch point coordinate of the sliding screen operation based on the current displacement, the historical displacement and the historical touch point coordinate of the sliding screen operation, determining the current reporting point coordinate based on the correction result, and enabling the current reporting point coordinate obtained according to the method to be closer to the current touch point coordinate, so that the degree of touch delay is reduced, and the touch experience of a user is improved.
