Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

In the related art, a gradient removal software filtering algorithm is generally used to suppress touch noise. However, due to the limitation of the algorithm, when the algorithm is used, the noise suppression effect is good, but the finger joint judgment algorithm is invalid, and whether finger joint touch is detected cannot be accurately identified. If this algorithm is not used, although the finger joint judgment is effective, noise suppression is ineffective, resulting in relatively large noise.

The disclosure provides a touch monitoring processing method for solving the above problems, under the condition that the current touch is determined to be single-point touch, firstly, a filtering matrix and a filtering result matrix corresponding to the current touch detection matrix are obtained, then, based on the position of the single-point touch, the filtering result matrix is compensated by using the filtering matrix, and then, based on the compensated matrix, finger joint touch judgment is performed, so that noise is suppressed, and accurate and reliable recognition results are ensured.

Touch detection methods, apparatuses, electronic devices, and storage media according to embodiments of the present disclosure are described below with reference to the accompanying drawings.

Fig. 1 is a flow chart of a touch detection method according to an embodiment of the disclosure.

As shown in fig. 1, the touch detection method may include the following steps:

step 101, under the condition that the current single-point touch to the touch panel is determined, a filtering matrix and a filtering result matrix corresponding to the current touch detection matrix are obtained.

The touch panel is an interactive input device, and a user can control the operation of the electronic device only by touching a certain position of the touch screen with a finger or a light pen.

The single-point touch refers to touch and click of a current touch panel operation as a position.

The touch detection matrix is initial touch data obtained when the touch panel is subjected to touch detection. In the touch detection matrix, each element value is a capacitance value obtained by current detection of a corresponding detection point.

In the disclosure, the elements in the touch detection matrix may be filtered by a gradient removal filtering algorithm to obtain a filtering result matrix. And then, based on the filtering result matrix, determining whether the current touch is single-point touch. Alternatively, the disclosure may also determine whether the current touch is a single touch based on other touch detection methods.

The gradient removing filtering algorithm is a filtering method in the touch algorithm, and the method comprises the steps of firstly calculating a touch detection matrix by using the gradient removing algorithm to determine a filtering matrix, and then subtracting the filtering matrix from the touch detection matrix to obtain filtered touch data, namely obtaining a filtering result matrix.

In some possible implementations, the current single touch for the touch panel is determined if each pixel point in the filtering result matrix having a value greater than the first threshold value is located in the same sub-matrix.

The first threshold is a preset touch signal threshold according to the nature and material of the touch panel, for example, the first threshold may be 400, 500, 600, etc., which is not limited in the disclosure.

Wherein, the submatrix is a matrix formed by partial row and column elements in the filtering result matrix. The size of the submatrix can be preset in the touch detection system or can be automatically generated by the touch detection system according to the use data collected by the history. The present disclosure is not limited in this regard.

It can be understood that if the current touch to the touch panel is multi-touch, the detection of finger joint touch is not needed at this time, and the detection of multi-touch gestures is directly performed.

In the disclosure, when the touch detection system detects that each pixel point with a value greater than the first threshold value in the filtering result matrix is located in the same sub-matrix, that is, the pixel points are adjacent, the current touch can be considered as single-point touch. If the pixel points are detected to be positioned in a plurality of non-adjacent areas, the current touch is considered to be multi-touch. The multi-point touch is a behavior of simultaneously performing touch on the touch panel by more than one point (two points, three points or more).

Optionally, under the condition that the current single-point touch to the touch panel is determined, the current touch detection matrix can be firstly obtained, then the forward gradient matrix and the reverse gradient matrix corresponding to the touch detection matrix are respectively determined, then the forward gradient matrix and the reverse gradient matrix are fused to obtain a filter matrix, and finally the touch detection matrix is subjected to filter processing based on the filter matrix to obtain a filter result matrix.

In the forward gradient matrix, the value of each element can be obtained by subtracting the difference value of the adjacent previous element from the value of the corresponding position element in the touch detection matrix. For example, the value of the third element in the forward gradient matrix can be obtained by subtracting the value of the second element from the value of the third element in the touch detection matrix. The first element of each row in the touch detection matrix may be subtracted by a fixed value to obtain the value of the first element in the forward gradient matrix, or the first element in the forward gradient matrix may be directly set to a fixed value. The present disclosure is not limited in this regard.

In the inverse gradient matrix, the value of each element can be obtained by subtracting the difference value of the next element from the value of the corresponding position element in the touch detection matrix. For example, the value of the second element of the inverse gradient matrix may be obtained by subtracting the value of the third element from the value of the second element of the touch detection matrix. The last element of each row in the touch detection matrix may be subtracted by a fixed value to obtain the value of the last element in the inverse gradient matrix, or the last element in the inverse gradient matrix may be directly set to a fixed value. The present disclosure is not limited in this regard.

The fusion of the forward gradient matrix and the reverse gradient matrix can be direct summation of elements at the same positions in the forward gradient matrix and the reverse gradient matrix, or weighted summation of elements at the same positions in the forward gradient matrix and the reverse gradient matrix. The present disclosure is not limited in this regard.

Step 102, based on each element in the first sub-matrix in the filtering matrix, compensating each corresponding element in the second sub-matrix in the filtering result matrix to obtain a third sub-matrix, wherein the first sub-matrix and the second sub-matrix contain elements corresponding to the current touch point.

The first submatrix is a matrix taking the largest element as a center in the filtering matrix. The size parameter of the first submatrix can be determined according to the size of a preset detection area for finger joint touch detection; alternatively, the size parameter of the first sub-matrix may be determined according to the historical touch data for the touch panel. The set value is a first sub-matrix size parameter preset in the touch detection system. For example, the first sub-matrix may be a matrix centered on the largest element, 7*7. The present disclosure is not limited in this regard.

The second submatrix is a matrix formed by partial elements with the same positions as the first submatrix in the filtering matrix in the filtering result matrix. The size of the second sub-matrix is the same as the size of the first sub-matrix.

The compensation of the corresponding elements in the second sub-matrix based on the elements in the first sub-matrix may be to add the elements in the first sub-matrix to the corresponding elements in the second sub-matrix; alternatively, the third sub-matrix may be obtained by weighted summation of the element values in the first sub-matrix and the corresponding element values in the second sub-matrix. The present disclosure is not limited in this regard.

In some possible implementations, since the area formed by the pixel points included in the second sub-matrix is generally larger than the touch area when the finger joint is touched, in order to reduce the calculation amount as much as possible in the case of avoiding the finger joint detection failure caused by the noise suppression result in the disclosure, it may be first determined whether the second sub-matrix may possibly cause the finger joint detection failure. The second sub-matrix is compensated only when it is determined that it may cause failure of the detection of the knuckle. For example, the difference between each second element value and the first element value in the second sub-matrix may be determined first, where the first element value is the maximum element value in the second sub-matrix, and when the ratio of the number of the difference values greater than the third threshold to the number of elements included in the second sub-matrix is greater than the fourth threshold, compensation is performed on each corresponding element in the second sub-matrix based on each element in the first sub-matrix, so as to obtain the third sub-matrix.

Wherein the second element value is the value of each element in the second sub-matrix.

The third threshold is a difference critical value between each element value in the second sub-matrix and the maximum element value in the second sub-matrix, which is preset in the touch detection system, and the values of the third threshold are not limited in the disclosure.

The fourth threshold, which is a proportional threshold preset in the touch detection system and is a proportional threshold for compensating each element of the second sub-matrix, may be 70%, 80%, 85%, and the like, which is not limited in the disclosure.

That is, only when the second sub-matrix is determined to include a larger number of pixels having a larger difference from the maximum pixel value, it can be determined that the noise-suppressed second sub-matrix may cause failure of detection of the finger joints, and thus compensation is required.

Step 103, identifying the third sub-matrix to determine whether the single touch is a finger joint touch.

In the disclosure, after the third sub-matrix is obtained, based on the data in the third sub-matrix, a subsequent judgment of finger joint touch control can be performed.

Fig. 2 is a flowchart of a touch detection method according to an embodiment of the disclosure.

As shown in fig. 2, the touch detection method may include the following steps:

in step 201, in case it is determined that the touch is currently a single touch for the touch panel, an output value of a pressure sensor associated with the touch detection matrix is obtained.

It should be noted that, in the case of determining that the current single-point touch is a single-point touch for the touch panel, the current single-point touch may also be a finger joint touch, and since the finger joint touch detection needs to be determined by combining with the pressure value, in the case of determining that the current single-point touch is determined, before determining whether the single-point touch is the finger joint touch, the output value of the pressure sensor associated with the current touch detection matrix may also be obtained.

Step 202, acquiring a filtering matrix and a filtering result matrix corresponding to the current touch detection matrix under the condition that the output value of the pressure sensor is greater than or equal to a second threshold value.

The second threshold may be a preset pressure demarcation value between finger joint touch and single-point normal touch according to the nature and material of the touch panel, which is not limited in the disclosure.

Alternatively, in the case where the output value of the pressure sensor is smaller than the second threshold value, it may be determined as a single touch, and the single touch is directly responded.

In the disclosure, when the output value of the pressure sensor is greater than or equal to the second threshold, it may be considered that the current touch may be a finger joint touch, and at this time, the filtering matrix and the filtering result matrix corresponding to the current touch detection matrix are acquired. And under the condition that the output value of the pressure sensor is smaller than the second threshold value, the current touch can be determined to be single-point touch, and the single-point touch can be responded directly. Therefore, time and resources wasted in executing the finger joint touch detection process when the output value of the pressure sensor is smaller than the second threshold value can be avoided.

And 203, respectively compensating each corresponding element in a second sub-matrix in the filtering result matrix based on each element in the first sub-matrix in the filtering matrix to obtain a third sub-matrix, wherein the first sub-matrix and the second sub-matrix contain elements corresponding to the current touch point.

In step 204, the third sub-matrix is identified to determine whether the single touch is a finger joint touch.

The specific implementation manner of steps 203 to 204 may refer to the detailed descriptions in other embodiments of the disclosure, and will not be described in detail herein.

In the embodiment of the disclosure, under the condition that the current single-point touch to the touch panel is determined, firstly, the output value of the pressure sensor associated with the touch detection matrix is acquired, and then, under the condition that the output value of the pressure sensor is greater than or equal to a second threshold value, the filtering matrix and the filtering result matrix corresponding to the current touch detection matrix are acquired. And then, respectively compensating each corresponding element in the second submatrix in the filtering result matrix based on each element in the first submatrix in the filtering matrix to obtain a third submatrix. And finally, identifying the third submatrix to determine whether the single-point touch is knuckle touch. Therefore, under the condition that single-point touch is determined, and the output value of the pressure sensor is greater than or equal to the second threshold value, the filtering result matrix is compensated by the filtering matrix, and finger joint touch judgment is performed based on the compensated matrix, so that time and resource waste is avoided, and accuracy and reliability of touch detection and identification results are greatly ensured.
