The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

An execution main body of the touch trajectory compensation method may be the touch trajectory compensation device provided in the embodiment of the present application, or a server integrated with the touch trajectory compensation device, where the touch trajectory compensation device may be implemented in a hardware or software manner.

As shown in fig. 1, fig. 1 is a first flowchart of a touch trajectory compensation method provided in the embodiment of the present application, and a specific flowchart of the touch trajectory compensation method may be as follows:

101. and receiving touch operation and acquiring the end position of the touch operation.

In an embodiment, the electronic device may receive a touch operation input by a user through a touch display screen, where the touch display screen is capable of acquiring the touch operation performed by the user on the touch display screen, and the touch operation includes, but is not limited to, acquiring a start point coordinate, an end point coordinate, a track of a sliding touch, and the like of the touch operation.

After receiving the touch operation, it may further be determined whether the trigger object of the touch operation is a living body, specifically, whether the touch object is a living body may be determined by acquiring a biometric feature of the touch object associated with the touch operation and determining whether the biometric feature is matched with preset biometric information. For example, the biometric information may be a heart rate parameter, an electrocardiographic parameter, a permittivity of the living body, frequency information related to the permittivity of the living body, or the like, as long as the biometric information is a parameter that can represent a characteristic of the living body, and is not limited thereto. Correspondingly, the preset biological information can be the heart rate parameter range of the human body, the electrocardio parameter range of the human body, the dielectric constant parameter of the human body, the frequency range related to the dielectric constant of the human body and the like, and the preset biological information can be any parameter capable of representing the human body. After determining that the trigger object of the touch operation is a living body, the step of acquiring the end point position of the touch operation may be further performed.

In one embodiment, the touch operation may include various types of operations, such as clicking, long-pressing, sliding, and the like, which are in contact with the touch screen. Taking a capacitive touch screen as an example, the capacitive touch screen determines a touch point by sensing a capacitance change generated by a human touch. It has two sets of signal lines: the driving line emits signals, and the sensing line detects the change of the capacitance value. When a finger touches the metal layer, the finger and the surface of the touch screen form a coupling capacitor due to the existence of an electric field of a human body, and for high-frequency current, the capacitor is a direct conductor, so that the finger sucks a small current from a contact point. The coupling between the two electrodes near the touch point is affected, thereby changing the capacitance between the two electrodes. When the mutual capacitance is detected, the electrodes in the driving line direction sequentially send out excitation signals, and all the electrodes in the sensing line direction simultaneously receive the signals, so that the change of capacitance values of all the intersection points of the transverse electrodes and the longitudinal electrodes, namely the capacitance of the two-dimensional plane of the whole touch screen, can calculate the coordinate of each touch point according to the two-dimensional capacitance variation data of the touch screen, and therefore, even if a plurality of touch points exist on the touch screen, the real coordinate of each touch point can also be calculated. Therefore, touch information including the x coordinate, the y coordinate of the touch point, the size (including the length, the width and the like) of the contact surface, the number of touched fingers and the like can be determined, and after the touch information is recognized, the coordinate information is reported to an upper layer through an input system, so that the touch operation occurring at a certain position of the screen can be detected by using the touch information, and the end point position of the touch operation can be determined.

102. Calculating the distance between the end point position and the touch edge area, and judging whether the distance is smaller than a preset distance, if so, executing step 103;

in an embodiment, after the end point position of the user touch operation is obtained, a distance between the end point position and the touch edge area may be further obtained. Specifically, in this embodiment of the application, the display area of the electronic device may include a touch edge area, as shown in fig. 2, fig. 2 is a schematic view of the touch edge area of the touch screen of the electronic device provided in this embodiment of the application, where the touch edge area may include a first touch edge area whose length direction is parallel to an X axis and a second touch edge area whose length direction is parallel to a Y axis, that is, two first touch edge areas of an upper side column and two second touch edge areas of an upper bottom column of the touch screen of the electronic device.

In an embodiment, the electronic device may set an area a preset distance away from the touch screen frame as the touch edge area. The preset distance may be set in length units, for example, an area 5mm away from the touch screen frame is set as a touch edge area. Optionally, the preset distance may also be set according to the number of pixels, for example, a region that is 100 pixels away from the touch screen frame is set as a touch edge region.

In calculating the distance between the end position and the touch edge area, the shortest distance between the end position and the touch edge area, such as the vertical distance between the end position and the touch edge area, may be calculated. The preset distance may be preset by the electronic device, or may be set by the user according to the usage habit, which is not further limited in the present application. When the distance between the end point position and the touch edge area is not less than the preset distance, it can be determined that the touch operation of the user does not reach the edge of the touch screen, the current process can be ended, and the touch operation subsequently input by the user can be continuously received.

103. And acquiring the position of a reference touch point before the end position.

In an embodiment, as shown in fig. 3, fig. 3 is a scene schematic diagram of a reference touch point position and a compensation point position provided in the embodiment of the present application, when a user performs a sliding operation on a touch screen, an electronic device may continuously record a sliding point, and when an end point B is determined, the electronic device may extend the first two points including the end point B to calculate a compensation point C coordinate for reporting, so as to achieve the purpose of extending the sliding. Therefore, the embodiment can acquire the previous sampling point a of the end point B as the reference touch point, and acquire the position of the reference touch point a.

In an embodiment, the reference touch point a may be an adjacent sampling point of the end point B, or may be a sampling point that is away from the end point B by a preset time interval, for example, a sampling point 0.1 second before the end point B may be obtained and used as the reference touch point, or a sampling point that is away from the end point B by a preset length interval, for example, a closest sampling point that is 10mm away before the end point B may be obtained and used as the reference touch point.

The position information of the end point and the reference touch point may be represented by coordinate values, for example, a rectangular coordinate system is established with a lower left corner of a touch screen of the electronic device as an origin, and horizontal and vertical coordinates of the end point and the reference touch point are respectively obtained as respective corresponding position information. In other embodiments, the rectangular coordinate system may further use the lower right corner, the upper left corner, and the upper right corner of the touch screen or the center of the touch screen as the origin.

104. And calculating the position of the compensation point according to the position of the end point and the position of the reference touch point.

In an embodiment, referring to fig. 3, when the point B is the last point of the touch operation, the electronic device may extend from the point a to the point B to calculate the position of the point C and report the position based on the point a and the point B.

In order to avoid that the position of the compensation point calculated according to the end position and the position of the reference touch point exceeds the screen, the maximum compensation length of the compensation point may be further limited, that is, the step of calculating the position of the compensation point according to the end position and the position of the reference touch point may include: and determining the maximum compensation length according to the touch edge area, and calculating the position of a compensation point according to the maximum compensation length, the end point position and the reference touch point position. Specifically, with continued reference to fig. 3, the maximum compensation length may be calculated by the slope of the line segment AB and the distance from the touch screen frame, for example, extending the line segment AB to the touch screen frame, and then calculating the distance between the end point B and the intersection point of the extension line and the touch screen frame, which may be used as the maximum compensation length.

As described above, the touch trajectory compensation method provided in the embodiment of the present application can receive a touch operation, obtain an end point position of the touch operation, calculate a distance between the end point position and a touch edge area, and determine whether the distance is smaller than a preset distance, if so, obtain a reference touch point position before the end point position, and calculate a compensation point position according to the end point position and the reference touch point position. According to the embodiment, when the touch operation is received in the touch edge area, the position of the compensation point located at the edge can be predicted according to the end position of the touch operation and the position of the reference touch point before the end position, so that the accuracy of the touch operation is effectively improved.

The method described in the previous examples is described in further detail below.

Referring to fig. 4, fig. 4 is a second flowchart illustrating a touch trajectory compensation method according to an embodiment of the present disclosure. The method comprises the following steps:

201. and receiving touch operation and acquiring the end position of the touch operation.

In an embodiment, the electronic device may receive a touch operation input by a user through the touch screen. When a user touches the touch screen, the touch screen detects touch information, and then the touch operation of the user is identified. The touch operation may include a single-point touch and a multi-point touch. When receiving multi-touch of a user, the touch operation corresponds to multiple touch points, for example, when the user inputs a sliding operation for the touch screen, the position of the last touch point of the sliding operation, that is, the end point position, may be obtained.

202. And determining a target touch edge area from the at least one touch edge area according to the end position, and calculating a vertical distance between the end position and the target touch edge area.

In an embodiment, the display area of the electronic device may include a touch edge area, and the touch edge area includes at least one touch edge area, such as a left touch edge area, a right touch edge area, an upper touch edge area, and a lower touch edge area, first, a closest end position may be determined from the at least one touch edge area according to the end position, and a target touch edge area may be determined from the at least one touch edge area as the target touch edge area, such as an end point B closest to the right touch edge area in fig. 3, and then the right touch edge area may be used as the target touch edge area, and a vertical distance between the end point B and the right touch edge area is calculated.

203. And judging whether the vertical distance is smaller than a preset distance, if so, executing the step 204.

For example, when the distance between the position of the end point B and the right touch edge area is smaller than the preset distance, it may be determined that the touch operation of the user involves the edge of the touch screen, the subsequent step 204 is continuously performed, and when the distance between the position of the end point B and the right touch edge area is not smaller than the preset distance, it may be determined that the touch operation of the user does not reach the edge of the touch screen, the current flow may be ended, and the touch operation subsequently input by the user may be continuously received.

204. And determining the sampling rate of the touch operation, and acquiring the position of a reference touch point before the end point according to the sampling rate.

In one embodiment, the sampling rate of the touch operation may be determined, wherein the unit of the touch sampling rate of the electronic device is Hz, which means how many signal samples are collected per second by the electronic device, and the number of samples per second, which is extracted from a continuous signal and is composed of discrete signals. The method can be simply understood as point position data, such as 120Hz, 240Hz and the like, which can be collected by the touch IC every second when a finger is pressed or slid on the touch panel, and then a sampling point a before the end point position is obtained according to the sampling rate and is used as a reference touch point to obtain the position information of the touch panel.

205. And determining the position of the initial compensation point on the connecting extension line of the end point position and the reference touch point position.

206. And determining a proportionality coefficient according to the position of the initial compensation point, and calculating the position of the target compensation point according to the proportionality coefficient.

Specifically, please refer to fig. 5, wherein fig. 5 is a schematic view of a scenario for calculating the compensation point according to an embodiment of the present application. In this embodiment, a denotes a reference touch point, B denotes an end point, C denotes an initial compensation point, and X _a Denotes the X coordinate of point A, X _b Denotes the X coordinate of point B, X _c Denotes the X coordinate of point C, X _ab Representing the difference of X coordinates of the AB point, X _ac Representing the difference in X coordinates of the AC points, Y _a Denotes the Y coordinate of point A, Y _b Denotes the Y coordinate of point B, Y _c Denotes the Y coordinate of point C, Y _ab Representing the difference in Y-coordinates of the AB points, Y _ac Representing the difference in the Y coordinates of the AC points, n _x Represents the maximum ratio of X availableCoefficient of case, n _y Representing the maximum available scaling factor for Y, wherein X is first calculated _ab And X _c ：

X _ab ＝X _b -X _a

N is obtained by calculation _x ：

n _x ＝(X _c -X _a )÷(X _b -X _a )

In the same way, in calculating Y _ab 、Y _c And n _y ：

n _y ＝(Y _c -Y _a )÷(Y _b -Y _a )

After obtaining the first scale factor n _x And a second scaling factor n _y Then, the smaller value can be selected as the target scale factor, and the coordinates of the target compensation point D are calculated according to the target scale factor, that is:

X _D ＝X _a +n×X _ab

Y _D ＝Y _a +n×Y _ab

thus, the step of determining a scaling factor from the initial compensation point location may comprise: calculating a first proportionality coefficient according to the initial compensation point position, the end point position and the abscissa of the reference touch point position, calculating a second proportionality coefficient according to the initial compensation point position, the end point position and the ordinate of the reference touch point position, and selecting a target proportionality coefficient from the first proportionality coefficient and the second proportionality coefficient.

In an embodiment, when the target scaling factor is selected, a preset scaling factor may be added for comparison, where the preset scaling factor may be preset for the electronic device, or may be set according to an area of the touch edge region. That is, the step of selecting the target scaling factor from the first scaling factor and the second scaling factor may include: and selecting a target proportionality coefficient from the first proportionality coefficient, the second proportionality coefficient and a preset proportionality coefficient.

In this way, the touch trajectory compensation method provided in this embodiment of the present application may receive a touch operation, obtain an end point position of the touch operation, determine a target touch edge area from at least one touch edge area according to the end point position, calculate a vertical distance between the end point position and the target touch edge area, determine whether the vertical distance is smaller than a preset distance, determine a sampling rate of the touch operation if the vertical distance is smaller than the preset distance, obtain a reference touch point position before the end point position according to the sampling rate, determine an initial compensation point position on a connection extension line between the end point position and the reference touch point position, determine a scaling factor according to the initial compensation point position, and calculate a target compensation point position according to the scaling factor. According to the embodiment, when the touch operation is received in the touch edge area, the position of the compensation point located at the edge can be predicted according to the end position of the touch operation and the position of the reference touch point before the end position, so that the accuracy of the touch operation is effectively improved.
