Description

Touch operation recognition method and device

Technical field

The present application relates to, but is not limited to, the field of touch screen technologies, and in particular, to a touch operation recognition method and apparatus.

Background technique

At present, the border width of the terminal screen is a key factor affecting the visual effect of the terminal. Each terminal manufacturer has successively launched a narrow border or even a borderless terminal to enhance the screen ratio and aesthetics. When a user uses a narrow border or a borderless terminal, the screen edge is inevitably touched. Sometimes the touch is a mistake, and sometimes the touch is not a malfunction. For example, when the user holds the mobile phone with one hand, the fingertips will touch the edges on both sides of the screen, and the mobile phone should not respond to the user's accidental touch operation. Another example: in the drawing application, the lines are drawn to the edge of the screen, and the phone should respond in real time for normal touch operations.

The solution to the edge mis-touch problem is basically: dividing the screen into an edge area and a non-edge area, and when detecting a touch, determining whether the contact position falls within the edge area, and if not, responding, if yes, then Touch operations in the edge area are suppressed. That is to say, as long as the contact position falls in the edge region, the terminal directly determines that the touch operation in the edge region is an accidental touch operation, and does not respond to the false touch operation. But this will lead to two problems: First, the continuous sliding of the finger in the edge area will not be responded; Second, in the continuous touch process, as long as the finger slides to the edge area will be suppressed, then the terminal system will consider the current touch action It has ended, but in fact the finger may not end the touch. For example, when a user draws a continuous curve, the curve is interrupted when the finger slides to the edge of the screen. It can be seen that the existing edge mis-touch solution cannot distinguish the different touch behaviors of the user, especially the inability to distinguish whether the touch behavior is edge mistouching behavior or edge touch behavior.

The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the embodiments described herein are merely illustrative of the application and are not limiting.

Embodiment 1

This embodiment provides a touch operation recognition method. FIG. 1 is a flow chart showing a touch operation recognition method according to a first embodiment of the present application. The execution subject of this embodiment is a terminal including a touch screen. As shown in FIG. 1, the touch operation identification method of this embodiment includes the following steps:

Step S110, acquiring touch data corresponding to the touch operation.

When a user (such as a finger) touches the touch screen, a touch signal generated in the touch screen may be detected; when the touch signal is detected, touch data corresponding to the touch operation may be acquired.

The touch data includes coordinate data capable of representing a contact area of the user and the touch screen.

The types of touch screens include: capacitive screens and pressure screens. The types of touch signals include: electrical signals and pressure signals.

Step S120, identifying whether the touch data is edge touch data. If yes, go to step S130; if no, go to step S160.

The touch screen is divided into an edge area and a non-edge area in advance. Touch operations are divided into edge touch operations and non-edge touch operations.

The edge touch data is touch data corresponding to a touch operation (edge touch operation) in the edge region. The non-edge touch data is touch data corresponding to a touch operation (non-edge touch operation) in the non-edge area. Wherein, the touch data is edge touch data or non-edge touch data according to the range information of the edge area and the non-edge area, and the coordinate data of the contact area of the user and the touch screen.

In an exemplary embodiment, the contact area of the user and the touch screen may be determined according to the touch data, and if the contact area is completely within the edge area or a predetermined proportion of the contact area falls within the edge area, it is determined that the touch data is edge touch data, Conversely, the touch data is determined to be non-edge touch data.

For example, if more than half of the contact area falls in the edge area, or as long as part of the contact area falls in the edge area, it can be determined that the touch data is edge touch data, and the user's contact behavior is edge contact behavior.

Step S130, determining whether the edge touch data conforms to a preset sliding touch condition. If yes, go to step S140; if no, go to step S150.

The sliding touch condition is a condition for determining that the current edge touch is a valid touch operation. In an exemplary embodiment, the sliding touch condition includes a condition that the current edge touch is a part of the continuous touch, in other words, the current edge touch and the previous edge touch are conditions of the continuous touch.

For example, the sliding touch condition includes: if the contact area of the edge touch is less than a preset threshold (contact area threshold), the edge touch is an effective touch operation. Then, based on the edge touch data, Determining whether the area of the edge touch is less than a preset threshold; if the contact area is less than the preset threshold, determining that the edge touch data meets a sliding touch condition; if the contact area is greater than or equal to the preset threshold, determining the edge touch The data does not match the sliding touch condition.

For another example, the sliding touch condition includes: if the current edge touch and the previous multiple touch form a continuous touch, the current edge touch is an effective touch operation. Then, using the touch data acquired before the edge touch data, it is determined whether the edge touch data conforms to the sliding touch condition. The following two scenarios are provided in this embodiment, but the following two scenarios are not intended to limit the present application.

In the first case, if the touch data acquired before the edge touch data is valid touch operation data, it is determined that the edge touch data meets the sliding touch condition, for example, the touch data acquired before the edge touch data is non-edge touch data. On the other hand, if the touch data acquired before the edge touch data is invalid touch operation data, it is determined that the edge touch data does not meet the sliding touch condition.

Case 2, determining, according to the edge touch data and the touch data acquired before the edge touch data, whether the edge touch data is data generated by touch jitter; if not, determining that the edge touch data meets a sliding touch condition; if yes, It is determined that the edge touch data does not conform to the sliding touch condition. Touch jitter refers to the jitter behavior that occurs when a finger makes a touch operation on the touch screen. The data generated by the touch jitter may be coordinate data, and the coordinates corresponding to the touch operation are closer to the coordinates when the touch shake occurs.

Step S140, determining that the edge touch data is valid touch operation data.

In the case where the edge touch data conforms to the sliding touch condition, it is determined that the edge touch data is valid touch operation data.

If the edge touch data meets the sliding touch condition, the edge touch is an effective touch operation, and the edge touch data is used as the touch operation data, and the corresponding touch operation is performed according to the touch operation data. The result of the operation can be displayed to the user through the terminal.

Step S150, determining that the edge touch data is invalid touch operation data.

In the case where the edge touch data does not conform to the sliding touch condition, it is determined that the edge touch data is invalid touch operation data.

If the edge touch data does not match the sliding touch condition, the edge touch is invalid this time. The touch operation can further recognize that the edge touch of the current edge is an edge touch, and the edge touch data can be discarded to suppress the invalid touch operation. By identifying whether the touch operation data is valid, it is possible to avoid the inconvenience caused by the edge misunderstanding.

Step S160, determining that the touch data is non-edge touch data, and determining that the non-edge touch data is valid touch operation data.

In this embodiment, touch data of a single finger on the touch screen is acquired and recognized. When multiple fingers touch on the touch screen, the touch data of each finger needs to be separately acquired and separately identified, and the touch data of each finger is recognized and Processing is independent of each other and does not affect each other. Wherein, the finger identifier assigned to the finger may be added to the touch data to distinguish the touch data of different fingers and separately identify and process. In the process of continuous touch of the same finger, the finger identifier of the touch data is the same.

In this embodiment, the current touch is an edge touch or a non-edge touch, and the edge touch can also identify an effective touch operation or an invalid touch. Through this embodiment, invalid touches can be suppressed, and normal touch is not affected.

Embodiment 2

The embodiment further describes the step of acquiring touch data, and FIG. 2 is a flow chart of the steps of acquiring touch data according to the second embodiment of the present application. This embodiment takes an electrical signal as an example. As shown in FIG. 2, the process of this embodiment includes the following steps:

Step S210, dividing the edge area and the non-edge area for the touch screen.

The edge area refers to a narrow area of the four edges of the touch screen, and the area other than the edge area of the touch screen is a non-edge area. For example, an area where the application icon is displayed on the touch screen is used as a non-edge area, and an area of the touch screen near the border of the terminal is an edge area.

According to the test statistics, reasonable edge areas and non-edge areas can be set in the touch screen. The area of the edge area is subject to the user experience.

Step S220, detecting an electrical signal generated in the touch screen.

The amount of signal generated in the touch screen is generated by the contact of the user's finger and the touch screen.

In an exemplary embodiment, the electrical signal generated in the touch screen is detected every predetermined time. For example, the electrical signal generated in the touch screen is detected every 10 ms.

Step S230, if it is detected that the feature of the semaphore of a certain area conforms to the touch feature, the obtained The area coordinates of the area.

Since the user may inadvertently touch the touch screen, it is necessary to determine whether the user's touch on the touch screen is a touch behavior (touch operation). If an area generates an electrical signal, and the feature of the semaphore meets the characteristics of the contact behavior, it may be determined that the current contact of the user and the touch screen is a touch behavior, the area is a contact area of the touch, and the acquired plurality of area coordinates are touch data.

The touch feature includes: an area of the area where the electrical signal is generated is greater than a preset area threshold, and the semaphore of the area is greater than a preset semaphore threshold.

In step S240, among all the area coordinates, the area coordinates in the edge area are determined, and the coordinate ratio R of the edge area is calculated.

The coordinate ratio of the edge regions R = the number of region coordinates in the edge region / the number of all region coordinates of the contact region.

For example, 100 regional coordinates are collected. The 100 regional coordinates can describe the shape of the contact area. In the 100 regional coordinates, 30 regional coordinates are in the non-edge region, and 70 regional coordinates are in the edge region. The coordinate ratio of the edge region is R=70/100=0.7.

In step S250, it is determined whether the coordinate ratio R is greater than a preset reference ratio. If yes, go to step S260; if no, go to step S270.

The baseline scale is used to measure whether the current touch of the user and the touch screen is an edge touch. The reference ratio can be set according to the statistical result of the edge touch test.

For example, the reference ratio is 0.9, the user touches the touch screen, and all the coordinates are in the edge region, then the coordinate ratio of the edge region is R=1, and the contact can be considered as the edge contact.

In step S260, it is determined that the current touch behavior is an edge touch, and the touch data is edge touch data.

In step S270, it is determined that the current contact behavior is a non-edge touch, and the touch data is non-edge touch data.

This embodiment can also use a pressure screen to further improve the accuracy of recognition. If the pressure screen is used, according to the pressure signal of the pressure screen, it is determined whether the current touch is a touch behavior, the coordinates of the pressure deformation region are collected, and the current touch behavior is determined as an edge contact behavior or a non-edge contact behavior according to the coordinate ratio of the edge region. .

Embodiment 3

This embodiment further describes the touch operation recognition of the edge area of the touch screen. FIG. 3 is a flowchart of a touch operation recognition method according to a third embodiment of the present application. As shown in FIG. 3, the method of this embodiment includes the following steps:

Step S310, in the edge touch data acquired this time, the maximum coordinate difference value is calculated according to all the area coordinates in the edge region.

The maximum coordinate difference value includes: a maximum coordinate difference value X _Δ and a maximum coordinate difference value Y _Δ .

The maximum coordinate difference value X _Δ is the maximum coordinate difference value of the abscissa in the edge region. In all the area coordinates in the edge area, all the abscissas are acquired, and the difference between the maximum value and the minimum value of the abscissa is calculated, and the absolute value of the difference is taken as the maximum coordinate difference value X _Δ .

The maximum coordinate difference Y _Δ is the maximum coordinate difference of the ordinate in the edge region. In all the area coordinates in the edge area, all the ordinates are acquired, and the difference between the maximum value and the minimum value of the ordinate is calculated, and the absolute value of the difference is taken as the maximum coordinate difference value Y _Δ .

In step S320, it is determined whether the maximum coordinate difference value is greater than the reference coordinate change value. If yes, go to step S390; if no, go to step S330.

The reference coordinate change value XY _{Δ is} used to measure whether the current touch behavior is a large area contact. Large-area contact refers to a large contact area between the palm and the edge of the user. For example, if the user holds the terminal, the entire thumb is in contact with the edge of the touch screen, and the area of the contact area is large at this time, so that at least one of the abscissa and the ordinate changes a large span. Among them, the reference coordinate change value XY _Δ needs to be set according to the statistical result of a large number of palm large-area contact experiments.

If the maximum coordinate difference is greater than the reference coordinate change value XY _Δ , it is determined that the contact is a large area contact. The maximum coordinate difference value includes: a maximum coordinate difference value X _Δ and a maximum coordinate difference value Y _Δ . At least one of the maximum coordinate difference value X _Δ and the maximum coordinate difference value Y _Δ is larger than the reference coordinate change value XY _Δ , and it can be determined that the maximum coordinate difference value is larger than the reference coordinate change value XY _Δ . The maximum coordinate difference value X _Δ and the maximum coordinate difference value Y _Δ are both smaller than the reference coordinate change value XY _Δ , and it is determined that the maximum coordinate difference value is not greater than the reference coordinate change value XY _Δ .

If it is determined that the touch is a large-area contact, it can be determined that the touch is not for the touch, and the touch can be regarded as an invalid touch operation and suppressed, and the touch data generated by the touch can be regarded as Invalid data and no need to escalate to the framework layer.

In step S330, it is determined whether there is a start data Data _start . If yes, go to step S380; if no, go to step S340.

The start data Data _start is touch data acquired before the edge contact data is acquired this time and has been recognized as valid touch operation data.

For example, in one continuous touch, the first touch data acquired is non-edge touch data, and the non-edge touch data is valid touch operation data, and the non-edge touch data is stored as start data Data _start for Follow-up use.

For another example, in a continuous touch, an edge touch data is acquired, and the edge touch data is not edge touch data generated by a large area contact, and compared with the previous touch data, it can be determined that the edge touch data is not data generated by the jitter. At this time, the touch operation data that the edge touch data is valid can be obtained, and the edge touch data is stored as the start data Data _start for subsequent use.

If there is a start data Data _start , it means that this edge touch behavior is part of one continuous touch. If there is no start data Data _start , it means that there is no valid touch operation data before the edge touch behavior, and further judgment is needed to determine whether the current edge contact behavior is valid.

In step S340, it is determined whether the temporary data Data _tmp exists. If not, step S350 is performed, and if yes, step S360 is performed.

The temporary data Data _tmp calculates the center coordinates of the previous contact area based on the previous acquisition of the touch data.

The calculation method of the central coordinates includes: determining the shape of the contact area according to all the area coordinates (X ₁ , Y ₁ ), (X ₂ , Y ₂ ), ..., (X _n , Y _n ) in the edge touch data; The shape of the contact area determines the center of the contact area; according to all the area coordinates of the contact area, the coordinates of the center of the contact area, that is, the center coordinates (X _center , Y _center ); wherein n>1, are determined.

The start data Data _start and the temporary data Data _tmp are only valid for the current touch behavior of the current finger, and the touch behavior of other fingers or the continuous touch behavior of the same finger twice before and after, respectively corresponding to different start data Data _start and Temporary data Data _tmp .

In step S350, the edge touch data acquired this time is temporarily stored as temporary data Data _tmp .

The center coordinates (X _center , Y _center ) of the edge touch data acquired this time are temporarily stored as temporary data Data _tmp for the next use.

Step S360, calculating a center coordinate according to the current edge touch data, and calculating a current coordinate rate of change according to the center coordinate and the temporary data Data _tmp .

Since the center coordinates include the abscissa and the ordinate, the temporary data includes the abscissa and the ordinate, so the current coordinate rate of change includes: the abscissa change rate R _x and the ordinate change rate R _y .

R _x =| (the abscissa in the center coordinate of this time - the abscissa in the temporary data) / the abscissa in the temporary data |. Where || means taking the absolute value.

R _y =| (the ordinate in the center coordinate of this time - the ordinate in the temporary data) / the ordinate in the temporary data |.

In step S370, it is determined whether the current central coordinate change rate is greater than the reference change rate R _std . If yes, go to step S380, if no, go to step S390.

The central coordinate change rate is greater than the reference change rate R _std , indicating that the current edge touch data is not data generated by touch shake, but is a normal slip.

If at least one of the abscissa change rate R _x and the ordinate change rate R _y is greater than the reference change rate R _std , it is determined that the central coordinate change rate is greater than the reference change rate R _std ; if the abscissa change rate R _x and the ordinate change rate R _{If y is} not greater than the reference change rate R _std , it is determined that the central coordinate change rate is not greater than the reference change rate R _std .

In step S380, it is determined that the current edge touch data is valid, and the current edge touch data is stored as the start data Data _start .

In step S390, it is determined that the current edge touch data is invalid.

After the edge touch data is recognized, the embodiment can discard the data generated by the large-area contact, identify the continuation data of the continuous touch, and eliminate the data generated by the jitter, thereby accurately identifying whether the edge touch is a touch or a false touch.

For example, the user draws a line in the touch screen, draws a line as a continuous touch process, and the line is drawn into the edge area from the non-edge area, and the touch data is acquired every 10 ms. For the edge touch data, it can be determined by the embodiment. The edge touch data obtained when drawing the line is not the data generated by the large-area contact, and the line is drawn from the non-edge area into the edge area, and there is the start data Data _start , then the edge touch data is valid touch operation data, The touch operation corresponding to the touch operation data may be performed, and the execution result is to display a line drawn by the user in the non-edge area.
