[0065] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0066] Figure 1 is a flow chart of a touch detection method for a touch screen according to an exemplary embodiment, the method is applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0067] Step S101: when the touch screen detects a touch operation, determining the operation type of the touch operation;

[0068] Step S102: determining a filtering algorithm according to the operation type;

[0069] Step S103: filtering the touch data generated by the touch screen according to the determined filtering algorithm to obtain filtered touch data;

[0070] Step S104: reporting a touch event according to the filtered touch data.

[0071] In the embodiments of the present disclosure, the terminal may be any electronic device with a human-computer interaction function, such as a mobile phone, a laptop computer, a tablet computer, a television, and any smart wearable device. The touch screen is used to implement the input and output functions of the human-computer interaction of the terminal. While displaying the screen, various functions can be implemented through the received touch operation.

[0072] The touch operation may include various gesture operations on various touch controls displayed on the touch screen or the entire touch screen, such as a click operation or a slide operation, etc. Through the combination of touch positions and touch gestures, various different operation instructions can be input.

[0073] During the touch operation of a touch object (such as a finger, stylus, etc.), there are various uncertainties in the gesture of the touch operation, including jitter and false touches caused by the touch area covering different touch controls. Therefore, in the process of obtaining touch commands based on the received touch data, it is necessary to accurately identify the gesture of the touch operation to prevent jitter and false touches from causing wrong commands to be executed.

[0074] In the disclosed embodiment, the touch data is processed by filtering to filter out jittery or mis-touch data, thereby accurately identifying the touch operation and executing the correct touch command.

[0075] In the disclosed embodiment, different filtering algorithms are used for touch operations of different gestures to perform targeted filtering to remove touch data generated by jitter or false touch, and then touch events are reported based on the filtered touch data, thereby effectively improving the accuracy of touch detection.

[0076] In some embodiments, when the touch screen detects a touch operation, determining the operation type of the touch operation includes:

[0077] The operation type of the touch operation is determined according to similarity between a first frame of touch data and a last frame of touch data generated by the touch screen based on the touch operation.

[0078] In the disclosed embodiment, a touch operation can be detected by a touch signal on the touch screen, such as a change in the capacitance value of a capacitor unit. Several frames of touch signals that continuously detect touch signals represent a touch operation. The first frame of touch data is the coordinate data carried by the first frame of signal in which a touch signal change is detected, and the last frame of touch data is the coordinate data carried by the previous frame of signal in which the touch signal returns to its original state (i.e., the signal state when there is no touch operation).

[0079] Based on the difference between the coordinate positions of the first frame of touch data and the last frame of touch data, it can be determined whether the touch object has moved during the touch operation. For example, if there is almost no movement, it can be considered a click operation; if there is movement, it can be considered a slide operation. This embodiment provides a way to accurately determine the type of operation.

[0080] In some embodiments, the type of touch operation can also be determined in combination with the duration of the touch operation. For example, a sliding operation usually takes longer time to act on the touch screen than a clicking operation. Therefore, the operation type can be determined based on a comparison of the duration of the touch operation and a time threshold.

[0081] In other embodiments, the touch area of ​​the touch operation may be combined to determine, for example, the touch area is compared with an area threshold, if it is larger than the area threshold, it may be considered as a sliding operation, otherwise it may be considered as a clicking operation.

[0082] Of course, the above is only an example of determining the operation type, and the specific implementation is not limited to any of the above.

[0083] In some embodiments, determining the operation type of the touch operation according to the similarity between the first frame touch data and the last frame touch data generated by the touch screen based on the touch operation includes:

[0084] If the similarity between the first frame touch data and the last frame touch data is greater than or equal to a similarity threshold, it is determined that the operation type is a click operation.

[0085] Since the touch operation will last for a period of time, and the touch screen detects touch through discrete signals. Therefore, the touch operation will generate multiple frames of continuous touch data. During the touch operation, the touch body is always in contact with the touch screen, so the position coordinates of each frame of touch data overlap. If the position coordinates of the first frame of touch data and the last frame of touch data are in the same area, it can be considered that the touch body is performing a click operation during the touch operation.

[0086] In the disclosed embodiment, whether it is a click operation can be determined based on the similarity between the first frame touch data and the last frame touch data. Since the touch data reflects the position coordinates of the touch screen receiving the touch operation, if the similarity between the first frame touch data and the last frame touch data is high, it means that the position of the touch object has hardly changed during the touch operation, so it can be considered as a click operation.

[0087] In some embodiments, Figure 2 As shown, in the above step S102, determining the filtering algorithm according to the operation type includes:

[0088] Step S11: If the operation type is the click operation, determine that the filtering algorithm is a ring filter; the ring filter is a filtering algorithm that filters out touch data at the edge of the touch area where the touch operation acts.

[0089] The touch data generated by the click operation on the touch screen is the coordinates of the position where the touch body touches the touch screen. It is understandable that because the area of ​​the touch screen where the touch body clicks may cover multiple touch points, or because the jitter during the touch process contacts multiple touch points within a larger range, and different touch points may correspond to different touch instructions, it is easy to cause inaccurate touch instructions. Here, the touch point refers to the touch unit on the touch screen used to sense the touch operation, for example, each touch capacitor unit in the touch array, each touch unit can generate a corresponding signal change under the action of the touch operation, thereby forming a touch signal, and the touch data representing the touch position can be obtained through the touch unit corresponding to the touch signal.

[0090] Therefore, in the disclosed embodiment, the touch data at the edge of the touch area where the touch operation is performed is filtered out by means of a circular filter, thereby reducing the area on the touch screen corresponding to the touch data coordinates, so that the touch points corresponding to the effective touch data (i.e., the touch data used to determine the touch command) correspond to the same touch command as much as possible. In this way, the redundant touch data generated due to the large touch contact area or jitter during the click operation can be reduced, thereby reducing the situation of inaccurate touch commands.

[0091] In some embodiments, in the above step S104, filtering the touch data generated by the touch screen according to the determined filtering algorithm to obtain filtered touch data includes:

[0092] Step S12: filtering out the touch data at the edge of the touch area corresponding to at least one frame of touch data generated by the touch operation according to the ring filtering;

[0093] Step S13: determining the remaining data after filtering the at least one frame of touch data as the filtered touch data.

[0094] Since the touch position targeted by the click operation remains unchanged, in the embodiment of the present disclosure, one or several frames of data from multiple frames of continuous touch data may be taken to perform the above-mentioned ring filtering, without considering the touch data of all frames.

[0095] By selecting one or several frames of data, the amount of data to be processed can be reduced and the processing speed can be increased. In addition, the deviation caused by jitter in the touch data can be reduced, thereby improving the accuracy of touch detection and quickly determining the touch instructions that need to be executed.

[0096] In some embodiments, filtering out the touch data at the edge position of the touch area corresponding to at least one frame of touch data generated by the touch operation according to the ring filtering includes:

[0097] According to the circular filtering, the touch data at the edge position of the touch area corresponding to the first frame of touch data generated by the touch operation is filtered out.

[0098] It is understandable that during the click operation, the click moment is usually closer to the position that the user actually intends to click, while the finger lifting process is more likely to cause jitter. Therefore, when filtering, the first frame of touch data is directly selected for filtering, and then the filtered first frame of touch data is used to determine the corresponding touch instruction.

[0099] In this way, not only can the touch operation be identified quickly and accurately, and the impact of jitter can be reduced, but also the complexity of data processing can be reduced, and the first frame of touch data can be directly filtered without the need for touch data selection and other processes.

[0100] In some embodiments, determining the operation type of the touch operation according to the similarity between the first frame touch data and the last frame touch data generated by the touch screen based on the touch operation includes:

[0101] If the similarity between the first frame touch data and the last frame touch data is less than a similarity threshold, and any two adjacent frames of data between the first frame touch data and the last frame touch data at least partially overlap, then the operation type is determined to be a sliding operation.

[0102] Corresponding to the click operation, if the touch operation is a sliding operation, the touch screen will detect that each frame within a continuous period of time can detect touch detection data. It can be understood that since the touch body slides from one touch position to another during the sliding operation, the position between the first frame touch data and the last frame touch data is different. Based on this, when the similarity between the first frame touch data and the last frame touch data is less than the similarity threshold, it can be determined that the touch body has moved during the touch operation, and therefore it is a sliding operation.

[0103] In addition, since the interval between each frame detection signal of the touch detection is short and the sliding speed of the sliding operation is relatively slow, it can be determined that the touch operation is a continuous sliding operation based on at least partial overlap of touch data between adjacent frames.

[0104] In some embodiments, Figure 2 As shown, in the above step S103, determining the filtering algorithm according to the operation type includes:

[0105] Step S21: If the operation type is the sliding operation, determine that the filtering algorithm is linear filtering; the linear filtering is a filtering algorithm that filters out the touch data at the edge position of the touch area affected by the sliding track of the sliding operation.

[0106] The touch control command corresponding to the sliding operation is generally determined according to the position corresponding to the sliding operation and the sliding direction. Therefore, if jitter occurs during the sliding operation, it may affect the judgment of the sliding direction, thereby causing the execution of the wrong touch control command. Therefore, filtering is used here to reduce the data generated by jitter in the sliding operation data.

[0107] In the embodiment of the present disclosure, unlike the click operation, the coordinates of the touch data of the slide operation are not all located in a fixed region or area, but there is touch data in a continuous area. Moreover, the touch positions corresponding to the touch data of different frames are different.

[0108] Therefore, in the embodiment of the present disclosure, a linear filtering method is used for the sliding operation, and the edge data is filtered out according to the connection line of the sliding track, so as to filter out the irregular data generated by the jitter during the sliding process and reduce the inaccuracy of the touch command caused by the jitter.

[0109] In some embodiments, in the above step S104, filtering the touch data generated by the touch screen according to the determined filtering algorithm to obtain filtered touch data includes:

[0110] Step S22, filtering out touch data at an edge of a touch area affected by a sliding track formed by connecting at least two frames of touch data generated by the touch operation according to the linear filtering;

[0111] Step S23: determining the remaining data on the sliding track after filtering as the filtered touch data.

[0112] Since adjacent frames of data overlap during the sliding operation, and the sliding trajectory can be approximately determined based on the connection line of touch data at different positions of several frames, it is not necessary to perform processing based on all touch data.

[0113] In the disclosed embodiment, two or more frames of touch data are selected from the touch data, and the connecting line of the corresponding positions of these frames of touch data is used as the touch trajectory. Then, the touch data at the edge position of the touch area where the touch operation sliding trajectory acts is filtered, so that the touch trajectory is a "thin line", thereby determining the accurate touch instruction.

[0114] In this way, since the sliding trajectory is determined based on the connection line of several frames of data, it is possible to remove some data generated by jitter during the actual sliding operation, and at the same time facilitate data processing.

[0115] In addition, after linear filtering, the range covered by the touch data is reduced, which can further reduce the data generated by jitter or the misjudgment of touch commands caused by an excessively large touch range.

[0116] In some embodiments, filtering out touch data at an edge of a touch area affected by a sliding track formed by connecting at least two frames of touch data generated by the touch operation according to the linear filtering includes:

[0117] According to the linear filtering, the touch data at the edge position of the touch area affected by the sliding trajectory formed by the connecting line between the two frames of touch data generated by the touch operation is filtered out; wherein the two frames of touch data include: any frame of touch data before the first frame of touch data and the last frame of touch data.

[0118] In the disclosed embodiment, the sliding trajectory can be determined based on the connection line between two frames of touch data in each frame of touch operation. Considering that when the touch body is performing a sliding operation, it is easy to generate jitter at the moment when the sliding ends and is lifted, thus changing the original sliding direction, the sliding trajectory can be determined based on the first frame of touch data and the frame of data before the last frame of touch data of the touch operation. In this way, the sliding trajectory can be quickly determined while reducing the misjudgment of touch commands caused by the jitter when the touch body is lifted, thereby improving the accuracy of touch detection.

[0119] The present disclosure also provides the following examples:

[0120] The disclosed embodiment performs different sampling and filtering processes for different touch operations without affecting the touch operation tracking property, that is, the touch operation delay is low, thereby achieving the anti-shake effect. Figure 3 As shown, the embodiment of the present disclosure performs touch detection through the following steps:

[0121] Step S301, determining the operation type by comparing the first frame touch data with the last frame touch data;

[0122] Step S302: If the first frame touch data and the last frame touch data correspond to the same valid event, it is a click operation;

[0123] Here, the valid event is a touch event corresponding to the same touch control or executing the same touch instruction, for example, a click operation on the same virtual button or application icon.

[0124] Step S303: If the first frame touch data and the last frame touch data correspond to different valid events, and any adjacent frames between the two frames are continuous, it is a sliding operation;

[0125] Step S304: if it is a click operation, perform ring filtering;

[0126] Step S305: If it is a sliding operation, linear filtering is performed;

[0127] Step S306: reporting coordinates according to the filtered data and executing corresponding touch commands.

[0128] Through the technical solution of the embodiment of the present disclosure, the data processing speed can be improved, and the misjudgment of touch commands caused by the jitter of touch operation during user use can be reduced, thereby improving the user experience. At the same time, different filtering algorithms are used for different operation gestures to reduce the jitter and freeze of the display interface caused by the jitter of touch operation.
