In particular, as users' requirements for terminal devices gradually increase, the touch screen can identify multiple touch points at the same time to meet the needs of users in multi-finger touch operation application scenarios. However, in this case, the touch screen may misrecognize the number of touch points. For example, when the user uses one finger to operate, it is considered to be two touch points, etc. Therefore, the touch points need to be appropriately merged. , to improve the accuracy of user touch operations and user experience.

Exemplary embodiments of the present disclosure provide a touch sensing processing method, which can be applied to a touch terminal, which may include a touch device such as a touch screen or a touch pad.

The touch element is provided in the terminal device and can be used to implement interactive operations between the user and the terminal device. This exemplary embodiment takes a touch screen as an example for subsequent explanation.

The touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can be used to receive user input signals. According to the working principle and transmission medium of touch screens, they can be divided into many categories, including resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave touch screens. Among them, capacitive touch screens are one of the most widely used types of touch screens in terminal equipment. one. In this exemplary embodiment, the touch screen may be a capacitive touch screen, which may work using the capacitive sensing principle of the touch screen.

Figure 2 shows an exemplary flow of the touch sensing processing method, including the following steps S210 to S230:

Step S210: Determine a distance threshold based on the number of touch points in historical touch events.

Among them, a touch event refers to an operation event in which the user comes into contact with the touch screen, such as an event in which the user clicks, presses, moves, or long-presses on the touch screen. The user can use a specific object, such as a finger, stylus, or other touchable Control objects, etc., and perform touch events with the touch screen to implement corresponding functions. Touch events can usually include a variety of information, such as when the user presses the touch screen with his fingers, the pressing force, the number of fingers used for pressing, the pressing area of the fingers, the sensing data generated by the pressing area, and the pressing time, etc.

When the user performs a touch operation on the touch screen, the touch screen can continue to collect data on the user's touch operation. Historical touch events refer to touch events before the current touch event. Specifically, they can be any time before the touch event corresponding to the current moment. Touch events, for example, the user performs a pressing operation on the touch screen for 2 seconds, and the current touch event is the pressing operation corresponding to the 2nd second, then the pressing operation corresponding to the 1st second can be a historical touch event, and the pressing operation corresponding to the 1.5th second can also be It can be a historical touch event, and the specific time granularity can be divided in more detail. This disclosure does not specifically limit this. In addition to determining historical touch events based on the time dimension, historical touch events can also be determined based on the touch screen's collection frequency of touch operations. For example, the touch screen periodically collects touch events. The current cycle corresponds to the current touch event, and the previous cycle corresponds to historical touch events, etc.

The touch point refers to the point that reflects the position or area of the touch screen where the user operates. In fact, the touch point can be regarded as the sensing area where the system can receive touch operations. For example, when the user uses two fingers to operate, the touch point can be The contact points between two fingers and the touch screen, the number of touch points is usually 2. In actual applications, due to differences in parameters such as the pressing method, strength, and angle when the user performs pressing operations, there may be two sensing areas on one finger. For example, the user uses the pulp of his thumb to press flat on the touch screen. During a touch operation, due to the large area of the fingertips, it may also be recognized as two or more touch points. Specifically, the touch screen can determine based on the sensing data of the sensing area actually received.

The distance threshold refers to a criterion used to determine whether different touch points need to be merged. In this exemplary embodiment, the distance threshold can be determined through historical touch events. In different application scenarios, the distance threshold can be adaptively adjusted to ensure a more effective convergence strategy.

In this exemplary embodiment, the touch screen may have its own independent memory and processor. When the touch screen receives a touch event input by the user, as shown in FIG. 3 , the touch screen 310 usually passes a specific pin, such as an INT pin or I2C (Inter-Integrated Circuit, two-wire serial bus)/SPI (Serial Peripheral Interface, serial peripheral interface) periodically triggers interrupt signals to enable the processor 320 of the touch terminal to read touch events, that is, In this exemplary embodiment, the touch event can be received by the touch screen system and reported to the touch terminal for information processing.

Step S220: Obtain the position of each touch point in the current touch event.

Furthermore, this exemplary embodiment can obtain the position of each touch point in the current touch event. Considering that the touch point is actually a point that can characterize the sensing area where the touch event currently occurs, the touch can be determined in the sensing area first. Click, and then get the position of the touch point. The position of the touch point may be the coordinates of the touch point on the touch screen, or the coordinate position on the sensing display interface, such as the coordinates in an interface composed of a receiving channel and a transmitting channel. In this exemplary embodiment, the touch terminal can directly read the position of the touch point from the touch screen system, or can return it to the touch terminal after the touch screen system determines the position of the touch point.

In an exemplary embodiment, as shown in Figure 4, the above touch sensing processing method may further include the following steps:

Step S410, obtain multiple touch areas in the current touch event;

Step S420: Determine a touch point in each touch area and obtain the location of the touch point.

Usually, when a user operates a touch screen, the touch screen will generate a corresponding sensing area according to the touch object. For example, when the user uses two fingers to operate, the two fingers can generate two or more sensing areas, and the sensing area will include a sensing area. Data, such as the sensing capacitance value generated corresponding to the pressed area. The sensing capacitance values at different locations are different. The above sensing area is the touch area. In this exemplary embodiment, a touch point may be determined in each touch area to characterize the current touch area. Specifically, the touch point of each touch area can be determined in a variety of ways. For example, the touch point can be any point in the sensing area, or it can be a certain point calculated based on the sensing data of each point in the sensing area, or it can It is the point in the sensing area where the sensing data is at a peak value, etc. In addition, the method of determining the touch point in each touch area may be the same or different, and this disclosure does not specifically limit this.

Specifically, in an exemplary embodiment, in the above step S420, determining a touch point in each touch area may include:

The point with the highest sensing signal value in each touch area is determined as the touch point of the touch area.

Among them, the sensing signal value refers to the sensing data generated after the touch screen receives the touch event input by the user, such as the sensing capacitance value. The point with the highest sensing signal value is the point with the highest sensing capacitance value. For example, Figure 5 shows a schematic diagram of the sensing capacitance values of different sensing points in a list composed of sending channels and receiving channels collected by the touch screen after the touch screen receives a touch event input by the user. As shown in Figure 5, the touch area S and the touch The sensing points included in area P have different sensing capacitance values, while the sensing capacitance values in other areas are basically 0. It can be considered that users in other areas have not performed touch operations. In this exemplary embodiment, the point with the highest sensing capacitance value can be That is, the point in the touch area S with an inductive capacitance value of 50 is determined as the touch point of the touch area S, and the point in the touch area P with an inductive capacitance value of 50 is determined as the touch point of the touch area P. It should be noted that in practical applications , the peak values of the sensing capacitance values in different touch areas may be different, and the details can be determined according to the actual situation. Figure 5 is only a schematic illustration.

Step S230: When it is detected that the distance between two touch points in the current touch event is less than the distance threshold, the two touch points are merged into one touch point.

This exemplary embodiment can determine whether to merge the two touch points by comparing the distance between the two touch points with a distance threshold. In other words, it can also be considered that based on the distance between the two touch points , determine whether to merge the touch areas corresponding to the two touch points, so that the touch terminal thinks that the current area is one touch area. For example, when the user uses the thumb pad to perform a pressing operation, two touch points are detected, but in fact the user Only single-finger touch is required. At this time, based on the above-mentioned judgment process of touch point merging, if the merging requirements are met, the two touch points can be merged into one touch point to ensure the current single-finger operation of the touch terminal for the user. for accurate identification.

Specifically, after merging two touch areas into one touch area, the touch point corresponding to the touch area can be determined in a variety of ways. For example, one of the touch points before merging can be used as the touch point after merging, or merging can be used. The previous two touch points are calculated to determine the merged touch point, etc. This disclosure does not specifically limit this.

In addition, in this exemplary embodiment, the distance between the two touch points in the current touch event can be determined by first obtaining the first distance between the two touch points in the first axial direction, and in the second The second distance in the axial direction, wherein the first axial direction is perpendicular to the second axial direction, for example, the first axial direction may be a horizontal direction, and the second axial direction may be a vertical direction, further, according to the second axial direction The first distance and the second distance are calculated based on the Pythagorean theorem to determine the straight-line path distance between the two touch points. In addition, other methods capable of calculating the distance between two touch points should also fall within the scope of the present disclosure.

In an exemplary embodiment, the above step S230 may include the following steps:

When the distance between any two touch points among the multiple touch points in the current touch event is detected to be less than the distance threshold, the multiple touch points are merged into one touch point.

In practical applications, multiple touch points may be detected. Whether to determine whether to merge multiple touch points to determine one touch point. In this exemplary embodiment, multiple touch points can be touched in pairs. distance judgment. When the distance between any two touch points is less than the distance threshold, it means that the current multiple touch points are very close. There is a high probability that they are multiple touch points determined by misjudgment. Therefore, they can be merged into A touch point.

To sum up, in this exemplary embodiment, the distance threshold is determined based on the number of touch points in the historical touch event; the position of each touch point in the current touch event is obtained; when it is detected that the distance between two touch points in the current touch event is less than When the distance threshold is reached, two touch points are merged into one touch point. On the one hand, this exemplary embodiment can determine whether two touch points need to be merged based on the judgment result of the distance between each touch point in the current touch event and the distance threshold, in a reasonable and effective manner, avoiding the need for the touch screen to Misidentification of the number of touch points leads to abnormal touch operations and improves user experience; on the other hand, the distance threshold is determined based on the number of touch points in historical touch events and has variability. When the number of touch points in historical touch events occurs When changing, different distance thresholds can be determined, that is, whether the distance between the two touch points in the current touch event meets the merging requirements of the touch points. It is not fixed and can be adapted according to the touch operations in actual applications. Adjustments for greater flexibility, reliability and accuracy of touch point merging.

In an exemplary embodiment, the above step S210 may include:

When the number of touch points in the historical touch event is less than the preset number threshold, determine the distance threshold as the first distance threshold;

When the number of touch points in the historical touch event is greater than or equal to the preset number threshold, determine the distance threshold as the second distance threshold;

Wherein, the first distance threshold is smaller than the second distance threshold.

In this exemplary embodiment, a preset quantity threshold can be set in advance to determine whether the number of touch points in historical touch events is too many, to determine which distance threshold to use for the current touch point, and to determine whether the touch points are aligned. This preset number threshold can be customized according to actual needs or application scenarios. For example, in some social applications, there are few scenarios that require users to perform touch operations with more than three fingers. Therefore, a preset can be set. The quantity threshold is 3. In a game application, a scenario may involve the user performing touch operations with multiple fingers. The preset quantity threshold can be set to 4 and so on. This disclosure does not specifically limit this.

When the number of touch points in historical touch events is greater than the preset number threshold, it is considered that the number of touch points may be incorrectly recognized. For example, when the preset number threshold is set to 4, when the number of touch points is determined to be 4, it may be that the user has used Four fingers are used to operate, or it may be that the user uses three fingers to operate and is mistakenly recognized as four touch points, etc. At this time, the touch points are more likely to be combined, so a larger second distance threshold can be determined. ; When the number of touch points in historical touch events is less than the preset number threshold, the recognition result of the current number of touch points is considered to be more accurate. Therefore, a smaller first distance threshold can be set, that is, when the user uses a finger between Only when they are very close will they be considered for merging. Among them, the first distance threshold and the second distance threshold can be customized according to actual needs. For example, the first distance threshold can be 5mm (millimeters) or 10 pixel units, and the second distance threshold can be 10mm or 20 pixel units, etc. , this disclosure does not specifically limit this. Based on this, this exemplary embodiment can realize that for different application scenarios, different distance thresholds can be set in a targeted and flexible manner to determine whether to converge the touch points.

In an exemplary embodiment, as shown in Figure 6, historical touch events include the last touch event, and the above touch sensing processing method may include the following steps:

Step S610, record the number of touch points of the last touch event through a preset variable;

Step S620: When the current touch event ends, update the preset variable according to the number of touch points in the current touch event.

This exemplary embodiment may set a preset variable for counting the number of touch points of the last touch event, such as the preset variable Mlast. This preset variable can be updated following changes in the time attributes of the touch event. For example, if the user performs a pressing operation for 2 seconds or more, the number of touch points corresponding to the touch event at the first second is 3, and the number of touch points corresponding to the touch event at the second second is The number of touch points is 2, then when the second second touch event is the current touch event, the default variable Mlast=3, when the second second second touch event ends and enters the next current touch event, the second second second touch event becomes a historical touch event, the default variable Mlast will be updated to 2.

In particular, in an exemplary embodiment, the above touch sensing processing method may further include the following steps:

When the current touch event is a lift event, the preset variable is set to 0.

If the current touch event is a lift event, for example, the user presses and then lifts, and the current touch event corresponds to the user's lift operation, it is considered that there is no need to judge whether the touch point of the touch event is in contact, because the preset can be The variable is set to 0 to facilitate the next update of the preset variable.

Figure 7 shows a flow chart of another touch sensing processing method in this exemplary embodiment, which may specifically include the following steps:

Step S702, obtain the current touch event;

Step S704, determine whether the current touch event is a lift event;

Step S706, if the current touch event is a lift event, set the preset variable to 0;

Step S708, if the current touch event is not a lift event, record the number of touch points of the last touch event through a preset variable;

Step S710, determine whether the number of touch points in the last touch event is less than a preset number threshold;

Step S712, if the number of touch points in the last touch event is less than the preset number threshold, determine the distance threshold as the first distance threshold;

Step S714, if the number of touch points in the last touch event is greater than or equal to the preset number threshold, determine the distance threshold as the second distance threshold;

Step S716, determine multiple touch areas in the current touch event, determine the point with the highest sensing signal value in each touch area as the touch point of the touch area, and obtain the position of the touch point;

Step S718, detect whether the distance between the two touch points in the current touch event is less than the distance threshold;

Step S720, if the distance between the two touch points in the current touch event is less than the distance threshold, merge the two touch points into one touch point;

Step S722: If the distance between the two touch points in the current touch event is greater than the distance threshold, no point processing is performed.
