In a specific implementation, the embodiment of the present invention may be applied to a mobile terminal, for example, a mobile phone, a tablet computer, a wearable device (such as VR (Virtual Reality) glasses, a VR helmet, a smart watch), and the like, which is not limited in this respect.
The mobile terminal is provided with a touch screen, namely an induction type display device capable of receiving input signals.

When the touch screen operates, multi-frame touch data are collected, wherein the touch data are provided with a plurality of sampling points, and each sampling point is provided with a sampling change value.
In order to make the embodiments of the present invention better understood by those skilled in the art, a capacitive touch screen is described as an example of a touch screen in the present specification.
For a capacitive touch screen, the sample change value is diff, i.e., a capacitance change value.
And 102, selecting the sampling point in the report point critical range as a sampling reference point.
In a specific implementation, for different touch screens, corresponding reporting point threshold values may be set, and a nearby range is determined as a reporting point critical range with the reporting point threshold value as a reference.
In a frame of touch data, the sampling point within the threshold range of the report point has a low sampling variation value, and may be a sampling point detected by touch in a non-hand-held state, and may be selected as a sampling reference point for further identification.
And 103, identifying a sampling target point triggered by touch in a non-hand-held state according to the sampling point adjacent to the sampling reference point.
In a frame of touch data, the sampling change value of the sampling reference point is used as a reference object, and compared with the sampling change values of other adjacent sampling points, if the change amplitude of the sampling change value is small, the sampling reference point and the surrounding sampling points can be regarded as sampling target points triggered by touch in a non-hand-held state.
And 104, performing sampling compensation on the sampling target point.
If the sampling target point is determined, sampling compensation can be performed on the sampling point based on the sampling target point, namely, the sampling change value of the sampling point is improved.
It should be noted that, for the detected touch data, sampling compensation may be directly performed on each frame of touch data (i.e., steps 102 to 104), or whether a preset condition is met may be determined, for example, whether the detected touch data is still (i.e., the acceleration is smaller than a smaller threshold and is close to 0), if the preset condition is met, a non-hand-held state may occur, sampling compensation is performed (i.e., steps 102 to 104), and the like, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, touch data is collected, the touch data comprises a plurality of sampling points, the sampling points in the critical range of the report points are selected as sampling reference points, the sampling reference points are identified as sampling target points triggered by touch in the non-hand-held state according to the sampling points adjacent to the sampling reference points, the sampling target points are used as references to perform sampling compensation on the sampling points, the sampling target points triggered by touch in the non-hand-held state are identified through the combination of the sampling reference points and the adjacent sampling points, the accuracy is high, the sampling compensation is performed after the sampling target points are identified, the accuracy of touch identification in the non-hand-held state is improved, the accuracy of report points is improved, multi-finger touch is performed in the non-hand-held state, the probability of missed report of the touch points is reduced, and the probability of misoperation is reduced.
Referring to fig. 2, a flowchart illustrating another step of a method for sampling and compensating touch data according to an embodiment of the present invention is shown, which may specifically include the following steps:
The touch data comprises a plurality of sampling points.
Referring to fig. 3A to 3D, exemplary diagrams of touch data according to an embodiment of the invention are shown.
In fig. 3A to 3D, each numerical value represents both the position of the acquisition point and the diff (sample variation value) of the acquisition point.
Fig. 3A shows that, in touch data triggered by a user holding the mobile terminal with one hand and touching the touch screen with 3 fingers with the other hand, the maximum value of diff (i.e., the square area in fig. 3A) of the collection point touched by the fingers of the user is over 600, and the data change amplitude is large.
Fig. 3B-3D show touch data triggered by a hand touching a touch screen with 4, 3, or 2 fingers, respectively, when the mobile phone is prevented from being plastic cut, the maximum value of the diff (i.e., the square area in fig. 3B-3D) of the collection point touched by the user's finger is substantially below 200, and the data change amplitude is small.
In the embodiment of the invention, the sampling change value of the sampling reference point is multiplied by the first proportion, so that the lower limit value of the critical report point can be obtained.
And multiplying the sampling change value of the sampling reference point by a second proportion to obtain the upper limit value of the critical report point.
The first ratio is smaller than 1, and the second ratio is larger than 1, so that the critical reporting point lower limit value is smaller than the reporting point threshold value, and the critical reporting point upper limit value is larger than the reporting point threshold value, thereby forming a reporting point critical range.
Generally, the critical hit threshold is smaller than the finger hit threshold.
The finger pointing lower limit value is a numerical value obtained by multiplying a pointing threshold by a certain multiple with respect to the characteristics of the user's finger.
For example, if the sampling point is X, the threshold value of the report is Limit, and the lower Limit value of the finger report is generally greater than 3 × Limit, the first ratio is 0.7, the second ratio is 2, and diff is used as the sampling variation value, the sampling variation value of X is diff (X), and 2 × Limit < diff (X) < 0.7 × Limit, X is defined as the sampling reference point.
And comparing the sampling change value of the sampling point in one frame of touch data with a critical report point lower limit value and a critical report point upper limit value, and setting the sampling change value between the critical report point lower limit value and the critical report point upper limit value as a sampling reference point.
And step 204, determining sampling points adjacent to the sampling reference point.
In the embodiment of the invention, the sampling points within a certain range from the sampling reference point are called as adjacent sampling points.
For example, the distance from the sampling reference point is 0 sampling point, the distance from the sampling reference point is 1 sampling point, the distance from the sampling reference point is 2 sampling points, and the like, which is not limited in this embodiment of the present invention.
And comparing the sampling change value of the sampling reference point with the sampling change value of the adjacent sampling point to obtain the sampling change amplitude.
If the sampling variation amplitude is within the set amplitude range, the sampling variation amplitude is small, and the sampling reference point can be considered as a sampling target point triggered by touch in a non-hand-held state.
In one embodiment of the present invention, the first range and the second range are divided with the sampling reference point as a reference, and the sampling points adjacent to the sampling reference point include sampling points adjacent to each other in the first range and sampling points adjacent to each other in the second range.
Wherein the first range is less than the second range.
In one example, the first range is shown in the following table:
| * | ||
| * | A | * |
| * |
the second range is shown in the following table:
| * | * | * |
| * | A | * |
| * | * | * |
where "a" represents a sampling reference point and "+" represents an adjacent sampling point.
In an embodiment of the present invention, step 205 may include the following sub-steps:
and a substep S11 of taking the third proportion and the fourth proportion based on the sampling variation value of the sampling reference point to obtain a first variation threshold value and a second variation threshold value.
And multiplying the sampling change value of the sampling reference point by the third proportion to obtain the first change threshold value.
And multiplying the sampling change value of the sampling reference point by the fourth proportion to obtain a second change threshold value.
Wherein the third ratio and the fourth ratio are both less than 1, and the third ratio is less than the fourth ratio, so the first variation threshold is less than the second variation threshold.
And a sub-step S12 of counting the number of sampling points having a sampling variation value greater than the second variation threshold value among the adjacent sampling points in the second range.
A substep S13, determining whether the adjacent sampling points in the first range are greater than or equal to the first variation threshold, and the number is greater than or equal to a preset number threshold; if yes, go to substep S14.
And a sub-step S14 of determining that the sampling variation amplitude between the sampling reference point and the adjacent sampling point is within a preset amplitude range.
If the sampling variation value of the adjacent sampling points is greater than or equal to the first variation threshold value in a first range around the sampling reference point a, and the number of the adjacent sampling points, of which the sampling variation value is greater than or equal to the second variation threshold value, is greater than or equal to the number threshold value in a second range around the sampling reference point a, the sampling variation amplitude between the sampling reference point and the adjacent sampling points can be considered to be within a preset amplitude range, that is, the sampling variation amplitude is smaller.
For example, assuming that the sampling reference point is a, the third ratio is 0.25, the fourth ratio is 0.5, diff is used as a sampling variation value, diff of 4 sampling points adjacent to the same row and column of a is greater than or equal to 0.25 × diff (a), and the number of sampling points having diff greater than or equal to 0.5 × diff (a) in 8 sampling points adjacent to a (the remaining 8 sampling points in the nine-square grid) is greater than or equal to 3, the sampling variation amplitude between the sampling reference point and the adjacent sampling points can be considered to be within a preset amplitude range.
And step 206, determining a sampling target point of touch trigger in a non-hand-held state through the sampling reference point.
In a specific implementation, the third range may be determined with the sampling target point as a reference, that is, a range at a certain distance from the sampling target point is defined as the third range (the third range may include the sampling reference point).
And marking the sampling points in the third range as sampling target points triggered by touch in a non-hand-held state.
In one example, the third range is shown in the following table:
| # | # | # |
| # | A | # |
| # | # | # |
where "a" represents a sampling reference point and "#" represents a sampling point in the third range (including a itself).
And step 207, performing sampling compensation on the sampling target point.
In a specific implementation, a fifth proportion may be taken for the sampling variation value of the sampling target point, and a sampling variation value after sampling compensation is obtained.
Wherein the fifth ratio is greater than 1, such as 1.5 (i.e., 50% offset); and the sampling change value after sampling compensation of the sampling reference point is at least larger than the report point threshold value.
