Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the embodiments of the present invention.
An embodiment of the present invention provides a possible touch acceleration method embodiment of a touch screen, please refer to fig. 1, fig. 1 is a flowchart of the method embodiment, and specifically includes steps 11 to 13.
Step 11, acquiring the current first standing position of the user.
Specifically, the pressure sensor array can be placed on the ground in front of the touch screen device, and the current standing position of the user can be obtained according to the signals returned by the pressure sensor array.
And step 12, inputting the first standing position into a trained relative acceleration region partition model to obtain a relative acceleration region corresponding to the first standing position.
Specifically, the relative acceleration region partition model is a deep learning model, and the embodiment of the invention uses the habit of using the touch screen by a user in a standing position to complete training of the relative acceleration region partition model. The trained relative acceleration region partition model can calculate and output a relative acceleration region corresponding to the first standing position according to the use habit of the user on the touch screen at the first standing position. The relatively accelerated region can be understood as a region predicted by the trained relatively accelerated region partition model and most likely to be touched by the user on the touch screen.
Step 13, adjusting the computing capability of the touch IC in the relatively accelerated region to a first value, and adjusting the computing capability of the touch IC in the relatively non-accelerated region to a second value.
Wherein the first value is greater than the second value; the relatively non-accelerating region is other regions of the touch screen region except the relatively accelerating region.
Specifically, in this embodiment, the computing capability of the touch IC is digitized, and the computing capability can be subdivided into 6 values in total, and as shown in fig. 2, the relationship between the computing capability and the values of the touch IC is shown, it can be seen that the smaller the values, the smaller the corresponding computing capability, and the larger the values, the larger the corresponding computing capability.
In order to conveniently regulate and control the operation capability, the invention also provides a preferred embodiment.
The specific scheme is as follows: and setting the first touch signal scanning frequency corresponding to the relatively accelerated region as a first value, and setting the second touch signal scanning frequency corresponding to the relatively non-accelerated region as a second value.
Specifically, the touch signal scanning frequency is a basic touch parameter of the touch screen, the higher the touch signal scanning frequency is, the faster the touch signal response of the touch screen is, that is, the positioning identification of the touch signal can be completed more quickly, but correspondingly, the higher touch signal scanning frequency increases more workload for the touch IC in unit time, and the touch IC is required to have higher operation capability.
Specifically, since the operation capability of the touch IC is fixed, the scanning frequency of the touch signal provided by the touch IC is usually fixed, and when the size of the touch screen is continuously increased, the scanning speed of the touch IC on the touch signal is continuously reduced under the condition that the operation capability is not increased, so that the positioning identification of the touch signal on the touch screen is affected. According to the embodiment of the invention, the touch screen area is divided into the relative acceleration area where the current user can perform touch operation with high probability and the relative non-acceleration area where the current user cannot perform touch operation with high probability, then the operation capability of the touch IC is redistributed, the touch signal scanning frequency of the relative acceleration area is improved, the touch signal scanning frequency of the relative non-acceleration area is reduced, and the positioning recognition speed and accuracy of the touch screen on the touch signal are ensured on the premise of not replacing the touch IC with higher performance.
Specifically, the touch screen in this embodiment is provided with a standard touch signal scanning frequency, and when the relative acceleration area of the touch screen is not divided, the touch screen performs touch signal scanning within the full screen range at the standard touch signal scanning frequency.
In an optimal example, the first value is larger than the standard touch signal scanning frequency, and the second value is smaller than the standard touch signal scanning frequency, so that hardware acceleration is realized on a relatively accelerated area, hardware deceleration is realized on a relatively non-accelerated area, and calculation force is intelligently distributed to an area frequently used by a user under the condition that the hardware performance is unchanged.
Of course, in other possible examples, the first value may be set to a standard touch signal scanning frequency and the second value may be set to a value less than the standard touch signal scanning frequency.
Of course, in other possible examples, the first value and the second value may both be less than the standard touch signal scan frequency.
Specifically, when the touch signal is not scanned in the relatively accelerated region and the relatively non-accelerated region by the touch screen device, the touch signal scanning frequency of the entire touch screen region may be reset to the standard touch signal scanning frequency, and the entire touch screen region may be scanned.
In a possible embodiment, the embodiment of the invention further provides a specific scheme for obtaining the trained relative acceleration region partition model.

In one possible example, the number of standing positions may be a left position, a middle position, and a right position.
Step 1.2, acquiring a historical touch area of the user performing historical touch operation in the touch screen at each of the plurality of standing positions.
Specifically, in the embodiment of the present invention, the historical touch areas corresponding to different standing positions are recorded in advance, and as shown in table 1, a specific recording table is provided. According to the embodiment of the invention, the historical touch area of the user for performing the historical touch operation in the touch screen at each standing position can be obtained by reading the table.

| 3 | Left side position | Rectangular regions of (x 5, y 5) to (x 6, y 6) | 09:35:50 |
| 4 | Intermediate position | Rectangular regions of (x 7, y 7) to (x 8, y 8) | 09:35:55 |
