The sensor layer can operate in multiple modes. If operating in mutual capacitance mode, the column and row traces form a single capacitive sensing node at each overlap point (e.g., a "vertical" mutual capacitance). If operating in self-capacitance mode, the column and row traces form two (vertically aligned) capacitive sensing nodes at each overlap point. In another embodiment, adjacent column traces and/or adjacent row traces may each form a single capacitive sensing node (e.g., a "horizontal" mutual capacitance) if operating in a mutual capacitance mode.

In the description of the present application, unless otherwise specified, "at least one" means one or more, "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

According to the cursor moving method provided by the embodiment of the application, the electronic device responds to the sliding operation in the touch area, detects a plurality of sliding events, responds to the operation that a finger or a touch pen leaves the touch area, determines the target position information according to at least two reference events, and then draws the moving track of the cursor according to the target position information. The at least two reference events include an end event, and the end event is a last detected sliding event in the plurality of sliding events. By executing the technical scheme, the electronic equipment can control the cursor to continuously move for a certain distance according to inertia when the finger of the user stops moving in the touch area.

Optionally, the plurality of sliding events may include an input event, a sliding event after the input event, and a last sliding event (i.e., an end event).

Optionally, each sliding event may include a touch time and position information of a touch point on the touch area when the electronic device detects the sliding event, where the touch time refers to a time when the electronic device detects the sliding event.

Optionally, the electronic device may determine the target location information according to at least two reference events, and may also determine the target location information according to a sliding event, for example, an end event, which is not limited herein.

Optionally, when the electronic device draws the movement track of the cursor according to the target position information, the target position information may be converted into position information of the cursor on the display, and then the track of the cursor may be drawn.

It should be noted that, in the embodiment of the present application, when the finger of the user stops sliding in the touch area, the electronic device may implement that the cursor continuously moves for a distance according to inertia in a plurality of implementation manners. As a possible implementation, the track prediction function may be started by default when the electronic device is turned on, and the electronic device may predict the track of the cursor when detecting that the user stops sliding. As another possible implementation, whether to start the trajectory prediction function may be set by the user in a system setting of the electronic device, considering that the user's requirements are different in different application scenarios. When the function is started, the electronic device can predict the track of the cursor when detecting that the user stops sliding. Of course, the prediction of the cursor trajectory may also be implemented by other implementation manners, and the embodiment of the present application is not particularly limited herein.

In an embodiment, as shown in fig. 6, a flow of a cursor moving method provided in an embodiment of the present application may include:

1. an input acquisition module of the electronic equipment receives sliding operation of a user and acquires a sliding event according to the sliding operation.

When a user performs a sliding operation through a finger or a peripheral device connected to the electronic device, such as a stylus or a mouse, the input acquisition module of the electronic device may receive the sliding operation of the user and obtain a sliding event according to the sliding operation.

In one embodiment, the sliding operation of the user is described as follows: in the scenario of fig. 1 where the electronic device is connected to a wireless keyboard, the sliding operation of the user may be a sliding operation performed by the user on a touch area through a finger or a stylus. The sliding operation refers to an operation that a finger or a stylus keeps in contact with the touch area all the time after contacting the touch area, and the electronic device can detect the sliding operation of the user in real time through a sensor layer coupled or integrated with the touch area. In a scenario where the electronic device is connected to a mouse, the sliding operation of the user may be an operation of the user sliding the mouse. Of course, the sliding operation of the user may also be an operation of the user in other scenarios, and the sliding operation of the user is not limited in this embodiment of the application.

The touch area may be a touch area of an input surface of the electronic device in fig. 3 (for example, when the electronic device is a tablet computer, the input surface may be a touch screen, and when the electronic device is a notebook computer, the input surface may be a touch pad). Alternatively, the touch area may be a peripheral device connected to the electronic device, for example, a touch area on a touch pad of the wireless keyboard in fig. 4.

In one embodiment, taking the sliding operation as an example of the sliding operation performed by a user through a finger on a touch area on a wireless keyboard connected to an electronic device, a processing procedure of receiving the sliding operation of the user by an input acquisition module and acquiring a sliding event according to the sliding operation is as follows: when a finger of a user touches a touch area of the wireless keyboard, the input acquisition module may detect an input event, which may specifically include position information of the finger on the touch area and a time when the input event is detected. When the finger of the user touches the touch area and does not leave the touch area to start the sliding operation, the input acquisition module may periodically detect a touch event of the user, where the touch event may include position information of the finger on the touch area at each detection and a time of each detection of the touch event. When the finger of the user leaves the touch area, that is, after the sliding operation is finished, the input acquisition module may use the last received touch event as an end event, where the end event may specifically include position information of the finger on the touch area, which is detected by the input acquisition module last time, and a time when the end event is detected.

As can be seen, the sliding event obtained by the input acquisition module may include: the touch input method comprises an input event of primary touch of a user and a plurality of touch events detected by an input acquisition module in the sliding process of the user. Wherein the plurality of touch events may include a last detected end event.

It is understood that, in the embodiment of the present application, the input acquisition module may determine the position information of the finger included in the sliding event on the touch region according to the contact area of the finger of the user and the touch region. In an embodiment, when the contact area between the finger and the touch area is smaller than the area threshold, the position information may be position information of a touch point between the mobile phone and the touch area. When the contact area between the finger and the touch area is larger than the area threshold, the position information may be the position information of the touch area between the mobile phone and the touch area. In this case, the position information may be position information of a center point of the touch area, or may be position information of other points of the touch area. Of course, the input acquisition module may also determine the position information included in the sliding event in other manners, and the embodiment of the present application does not limit the position information included in the sliding event. The position information may be a two-dimensional coordinate of a certain point.

It should be noted that, in the embodiment of the present application, the input acquisition module periodically detects multiple touch events. And the last touch event of the plurality of touch events is taken as an end event. This is because the input acquisition module periodically detects the touch event, and the duration of each period may be the same or different, so that the touch event detected in the last period of the input acquisition module may be obtained at the moment when the finger of the user leaves the touch area, and the touch event detected in the last period may also be obtained before the finger of the user leaves the touch area, but the finger of the user has left the touch area before the touch event is detected next time by the input acquisition module. That is, the position information of the finger on the touch area included in the end event may refer to the position information of the finger when the finger leaves the touch area, or may refer to the position information of the finger before the finger leaves the touch area. Alternatively, it may also be understood that the time of detecting the end event included in the end event may refer to a time when the finger leaves the touch area, and may also refer to a time earlier than the time when the finger leaves the touch area. The relationship between the position information of the finger on the touch area and the finger leaving the touch area, which is included in the end event, may be determined according to a preset period and an actual scene.

In addition, the period of the touch event detected by the input acquisition module can be obtained by a background worker through preliminary experiments and stored in the electronic device. Alternatively, the period may be derived from a screen refresh frequency of the electronic device. For example, assuming a screen refresh rate of N times per second, the period may be (1/N) second. Of course, the period may also be determined according to other ways. The embodiment of the application does not limit the period of the touch event detected by the input acquisition module and whether the duration of each period is the same.

2. And the input acquisition module sends the acquired sliding event. In a specific implementation, 2201, the input acquisition module sends the acquired sliding event to an input distribution module of the electronic device. 2202, the input acquisition module sends a swipe event to an input cache module of the electronic device. 2203, the input collection module sends an end event to the path prediction module of the electronic device.

After each sliding event is acquired by the input acquisition module, the acquired sliding event can be respectively sent to the input distribution module and the input cache module. And the input acquisition module can send the end event to the path prediction module after acquiring the last sliding event, namely the end event.

3. The input cache module receives the sliding event sent by the input acquisition module and stores the received sliding event.

After the input acquisition module sends the sliding event to the input cache module, the input cache module may receive and store the position information and the time information included in the received sliding event one by one, and the position information and the time information are used for predicting the display position of the cursor by the path prediction module after the finger of the user leaves the touch area.

4. And the input distribution module receives the sliding event sent by the input acquisition module and executes operation according to the sliding event.

The input collection module, after sending the slip event to the input distribution module, the input distribution module may perform an operation based on the received slip event.

For example, the input distribution module may determine a first position of a cursor in a display of the electronic device according to the position information included in the sliding event. That is, the input distribution module may convert the position information of the user's finger on the touch area into the first position information of the corresponding cursor in the display. Alternatively, the input distribution module may send the sliding event to other modules, so that the other modules perform position conversion. Wherein. The other modules may be modules of a system service layer, an application framework layer, and an application layer, and the embodiments of the present application are not limited. Alternatively, the conversion of the position information of the finger on the touch area into the first position information of the cursor in the display may also be performed by another module (that is, the sliding event does not need to be sent to the input distribution module, and may be sent to the other module by the input acquisition module), and the conversion of the first position information is specifically performed by which module performs the embodiment of the present application, and is not limited herein.

For example, the input distribution module may further draw a track of the cursor according to the first position information, and send the drawn track to the application layer for real-time display. Or, the input distribution module may send the converted first position information of the cursor to the application framework layer, and the application framework layer performs drawing of the cursor. Or, the input distribution module can also send the first position information to the application program layer, and the application program layer draws a cursor. The embodiment of the application does not limit the layer of the android system where the cursor is drawn and the module where the cursor is drawn.

It should be noted that, in the embodiment of the present application, the correspondence between the position in the touch area and the position of the cursor in the display may be stored in the electronic device in advance. The correspondence between the two can be obtained by a function or algorithm.

For example, in the embodiment of the present application, the drawing process of the cursor may be: the input acquisition module acquires touch point coordinates included by the sliding event and reports the touch point coordinates to an input map (input map) module. The input mapping module converts the touch point coordinates in the sliding event into coordinates of a cursor in a screen. The input mapping module reports the coordinates of the cursor to a pointer controller. The pointer controller reports the coordinates of the cursor to a mouse controller (sprite controller). And calling a screen drawing interface by the mouse controller to draw a cursor on the screen.

5. The path prediction module receives the end event sent by the input acquisition module, and determines at least one piece of target position information based on the sliding event stored in the input cache module.

After the input acquisition module sends the end event to the path prediction module, the path prediction module may trigger execution of path prediction in response to the received end event, that is, determine a possible sliding trajectory according to inertia after the finger of the user leaves the touch area. For example, the path prediction module may determine at least one target location information based on all the sliding events corresponding to the sliding operation of the user stored in the input cache module. The target position information is information of a position where a finger of the user may be located according to inertia after leaving the touch area. Generally, the faster the user's finger slides on the touch area, the greater the amount of target position information, and thus the longer the sliding trajectory of the cursor in the display according to inertia after the finger leaves the touch area.

For example, the path prediction module may determine the at least one target location information in several ways.

Mode 1, the path prediction module determines at least one target position information based on two slip events and a preset motion deceleration.

It is understood that in the embodiment of the present application, there are many implementations of the selection of the two sliding events. For example, the two sliding events may be any two sliding events of all sliding events corresponding to the sliding operation stored in the input buffer module. Alternatively, two of the sliding events may include an end event, and the remaining other event may be any one of all sliding events corresponding to the sliding operation except the end event. For example, the two slip events may include an end event and one slip event prior to the end event. Alternatively, the two sliding events may be two events near the end event. The embodiment of the present application is not limited to specifically selecting which two sliding events.

In addition, in the embodiment of the present application, the preset movement deceleration may be previously obtained by experiment and stored in the electronic device.

In one embodiment, the path prediction module may determine at least one target position information according to two position information and two time information of the two sliding events, and a preset motion deceleration and a period (a period for the input acquisition module to detect the touch event according to the sliding operation). For example, the target position information may be coordinates of a point predicted in the touch area. In this case, the path prediction module may determine the origin coordinates before determining the at least one target location information. For example, the position of the input event corresponding to the slide operation here may be defaulted as the origin.

For example, for ease of understanding, the target position information is assumed to be two-dimensional coordinates of a certain point on the touch area. And assuming that the two slip events include an end event and a previous slip event of the end event, the above target position information may be obtained according to the following equations (1) and (2):

where Δ Xi is a difference between an abscissa of the ith target position and an abscissa of a position included in the end event, and Δ Yi is a difference between an ordinate of the ith target position and an ordinate of the position in the end event. (Δ xn, Δ yn) are the coordinates of the location that the end event includes, and Δ Tn is the time information that the end event includes, i.e., the time at which the input acquisition module detected the end event. (xn, yn) is the coordinates of the location included by the sliding event that precedes the end event, and Tn is the time information included by the sliding event that precedes the end event, i.e., the time at which the input acquisition module detected the sliding event that precedes the end event. Alpha is a preset deceleration of the movement. Δ Ti is a time corresponding to the ith target position, and may be obtained according to Δ Tn and a period T of the input acquisition module for detecting the touch event according to the sliding operation, for example. For example, Δ Ti ═ Δ Tn + i × T when the time length of each cycle is the same. As another example, Δ Ti may be obtained from the preconfigured duration and Δ Tn.

After the path prediction module obtains Δ Xi and Δ Yi by using the formula (1) and the formula (2), the coordinates of the ith target position can be determined, and the coordinates of the ith target position are (Δ xn + Δ Xi, Δ yn + Δ Yi).

It should be noted that, in the embodiment of the present application, the coordinate point of the target position is located on a straight line defined by two positions of two sliding events. That is, the cursor in the display of the electronic device slides along the inertia sliding trajectory as a straight line, which is the same as the straight line determined according to the positions of the two cursors after the two position transitions in the two sliding events. And the cursor only slides for a distance according to inertia, and the path prediction module can predict the path according to the distance

Calculating the initial speed in the horizontal direction and adopting the formula:

let V be 0 and calculate Δ Ti to obtain the maximum time to slide in the horizontal direction. And the path prediction module may be based on

Calculating the initial speed in the vertical direction and adopting the formula:

let V be 0 and calculate Δ Ti, resulting in the longest time to slide in the vertical direction. The smaller Δ Ti of these two longest times from which the number of target positions can be determined. For example, assuming that the duration of each cycle is the same, dividing Δ Ti by the cycle by a whole can yield the number of target positions.

For example, assume that the user's finger performs a sliding operation on the touch area, electricallyThe child device acquires 4 sliding events, as shown in fig. 7A, where the 4 sliding events include: input event 1, slide event 2, slide event 3, end event 4. The input event 1 includes location information (x1, y1) and time information T1. The slide event 2 includes position information of (x2, y2) and time information of T2. The slide time 3 includes position information of (x3, y3) and time information of T3. The end event 4 includes location information of (Δ xn, Δ yn) and time information of Δ Tn. Assuming that the position of the input event 1 is the origin, i.e., x1 is 0 and y1 is 0, the two slide events include an end event and a previous slide event of the end event. And assuming that the number of the target positions calculated by the path prediction module is 3, the time length of each period is T. Then, as shown in FIG. 7A, the 1 st target position has coordinates of

Δ T1 ═ Δ Tn + T. The 2 nd target position has coordinates of

Δ T2 ═ Δ Tn + 2T. The coordinates of the 3 rd target position are

ΔT3＝ΔTn+3T。

Mode 2, the path prediction module determines at least one target location information based on the three sliding events.

It is understood that, in the embodiment of the present application, the three sliding events may be any three sliding events in all sliding times corresponding to the sliding operation stored by the input buffer module, or may be three sliding events close to the end event. For example, in order to ensure the accuracy of the sliding trajectory of the cursor predicted by the path prediction module, three last detected sliding events, namely, an upcoming end event, and the first two sliding events of the end event may be selected as the three sliding events. The embodiment of the present application does not limit which three sliding events are specifically selected.

In one embodiment, the path prediction module may determine at least one target location information based on the three sliding events. For example, the path prediction module may determine the circle center coordinates and the circle radius according to the three position information, and determine the arc distance of the finger according to the inertia after the finger leaves the touch area based on the information included in the three sliding events. Thereafter, the path prediction module determines at least one target location information based on the circle center coordinates, the circle radius, and the arc distance. The target position information may be two-dimensional coordinates of a point predicted in the touch area.

For example, for ease of understanding, the target position information is assumed to be two-dimensional coordinates of a certain point on the touch area. And assume that the three slide events include an end event and the first two slide events of the end event, wherein the end event includes a position coordinate of (x) _n ，y _n ) Time information is T _n The position coordinate included in the sliding event before the end event is (x) _n-1 ，y _n-1 ) Time information is T _n-1 The second sliding event before the end event includes a position coordinate of (x) _n-2 ，y _n-2 ) Time information is T _n-2 . The path prediction module may determine the abscissa and ordinate of the center of the circle from these three coordinates and determine the radius of the circle from the coordinates of the center of the circle. Wherein, the abscissa of the center of the circle satisfies the following formula (3), the ordinate of the center of the circle satisfies the following formula (4), and the radius of the circle satisfies the following formula (5).

Wherein X is the abscissa of the center of the circle, Y is the ordinate of the center of the circle, and R is the radius of the circle. And A, B, C, D, E, F satisfy the following formulas, respectively.

A＝x _n -x _n-1

B＝y _n -y _n-1

C＝x _n -x _n-2

D＝y _n -y _n-2

The path prediction module may determine an arc distance for each target location relative to the location of the end event based on information included with the three slip events. The pitch arc distance satisfies the following formula (6)

Where α is a preset deceleration of motion. Δ Ti is a time corresponding to the ith target position, and Δ Ti is based on T _n And the input acquisition module is used for detecting the period T of the touch event according to the sliding operation. For example, when the time lengths of each cycle are the same, Δ Ti ═ T _n +i*T。

The path prediction module, after determining the coordinates of the center of the circle, the radius of the circle, and the arc distance of each target location relative to the location of the end event, may determine each target location information based on the coordinates of the center of the circle, the radius of the circle, and the arc distance. The target position information satisfies the following formula (7) and formula (8).

Where Δ Xi is the abscissa of the ith target position, and Δ Yi is the ordinate of the ith target position.

In the embodiment of the present application, the trajectory of the cursor in the display obtained in the manner 2 slides by inertia is an arc. Also, the number of target positions may be configured in the electronic device in advance. For example, the number of target locations may be obtained according to a screen refresh frequency of the electronic device and a preset time duration. For example, assuming that the screen refresh frequency is N times per second and the preset time duration is M, the number of target locations may be (M × N). Alternatively, the number of target locations may be a fixed value that is pre-configured. Of course, the number of target positions may also be obtained by other ways, and the embodiment of the present application is not limited herein.

For example, assuming that when the finger of the user performs a sliding operation on the touch area, the electronic device acquires 4 sliding events, as shown in fig. 7B, where the 4 sliding events include: input event 1, slide event 2, slide event 3, end event 4. The input event 1 includes location information of (x1, y1) and time information T1. The slide event 2 includes position information of (x2, y2) and time information of T2. The slide event 3 includes position information of (x3, y3) and time information of T3. The end event 4 includes location information of (x4, y4) and time information of T4. Assuming that the position of the input event 1 is the origin, i.e., x1 is 0 and y1 is 0, the three slide events include an end event and the first two slide events of the end event. And assuming that the number of the preset target positions is 3, the duration of each period is T. Then, as shown in fig. 7B, the path prediction module determines coordinates (X, Y) of the center of the circle according to the three position information of the sliding event 2, the sliding event 3 and the end event 4, determines a radius R of the circle, and further determines an arc distance S corresponding to each of the 3 target positionsAnd i, then determining the coordinates of the 3 target positions according to the coordinates of the circle center, the circle radius and the arc distance. Wherein the 1 st target position has coordinates of

Δ T1 ═ T4+ T. The 2 nd target position has coordinates of

Δ T2 ═ T4+ 2T. The coordinates of the 3 rd target position are

ΔT3＝T4+3T。

Mode 3, the path prediction module determines at least one piece of target position information based on all the sliding events corresponding to the sliding operation.

In one embodiment, the path prediction module may determine at least one target location information based on the location information and the time information of all the sliding events corresponding to the sliding operation, and using a pre-stored trajectory prediction algorithm.

It is understood that, in the embodiment of the present application, the number of target locations may be a fixed value configured in advance, or may be obtained according to a screen refresh frequency of the electronic device and a preset time length. The embodiments of the present application are not limited herein.

In addition, the pre-stored trajectory prediction algorithm may be a trajectory prediction model or a trajectory prediction formula. The trajectory prediction model or the trajectory prediction formula may be obtained by acquiring sample data in advance and training the sample data in a machine learning manner. In order to ensure the accuracy of the trajectory prediction algorithm, the sampling data may be a large amount of position data and time data of the finger sliding on the touch area, and coordinate point data predicted manually.

It is to be noted that, in the embodiment of the present application, the trajectory prediction model may be obtained by the electronic device through training data of the electronic device, or may be sent to the electronic device after obtaining the cloud training data, or may be obtained through manual calculation and stored in the electronic device. The embodiment of the present application does not limit the manner of obtaining the trajectory prediction model in the electronic device.

In some embodiments, the sampling data for training the trajectory prediction model may be acquired by the electronic device, or may be acquired by the cloud. For example, the sample data may be historical swipe data acquired by the electronic device for a user using the electronic device. For another example, the sampling data may be historical sliding data of users of the whole network acquired by the cloud, or may also be historical sliding data of certain types of people. The embodiment of the present application does not limit the source of the sampling data and the type of the sampling data.

Further optionally, the above-mentioned sampling data for training the trajectory prediction model may also be all historical sliding data within a preset time period. For example, the sample data may be historical slip data in the previous day, the previous week, the previous month, or the previous year in which the cursor movement method in the embodiment of the present application was performed. The time period for acquiring the sampling data is not particularly limited in the embodiments of the present application.

In some embodiments, when training the trajectory prediction model using the sample data, the trajectory prediction model may be classified according to the shape of the sliding trajectory of the user, and then a trajectory prediction model may be trained by combining different types of sliding trajectories, or a trajectory prediction model may be trained for each type of sliding trajectory. The type of the sliding track may include a straight line, an arc line, an irregular curve, and the like. The embodiment of the present application does not specifically limit the training process of the trajectory prediction model.

For example, the path prediction module may determine a time corresponding to each target position according to the time information included in the end event and the period for detecting the slip event. Then, the path prediction module may input the position information and the time information in all the sliding events and the time corresponding to a certain target position into a trajectory prediction model or a trajectory prediction formula to obtain the coordinates of the target position.

For example, the trajectory prediction formula may be the following formula (9) and formula (10).

Where Δ Xi is the abscissa of the ith target position, and Δ Yi is the ordinate of the ith target position. a1, a2.. an, and b1, b2... bn are preset parameters, and are pre-trained. (x) ₁ ，y ₁ ) Is the coordinates of the position in the input event and T1 is the time information in the input event. (x) ₂ ，y ₂ ) Is the coordinates of the position in the first slip event after the input event and T2 is the time information in this slip event. (x) _n ，y _n ) Is the coordinates of the location in the end event and Tn is the time information in the end event. Δ Ti is a time corresponding to the ith target position, and may be obtained according to Δ Tn and a period T of the input acquisition module for detecting the touch event according to the sliding operation, for example. For example, Δ Ti ═ Δ Tn + i × T is the same for each cycle. As another example, Δ Ti may be obtained from the preconfigured duration and Δ Tn.

And the path prediction module substitutes the data included by all the sliding events corresponding to the touch operation into the coordinate formula of the ith target position to obtain the coordinate of the ith target position. It is to be understood that, after the at least one target position information determined in the above manner 3 is converted into the position information of the cursor in the display, the shape of the trajectory of the cursor in the display may be implemented in any way. For example, the sliding track of the supplementary cursor may be a straight line, an arc line, or a line with an unspecified shape, which may be determined by the actual scene.

Mode 4, the path prediction module determines at least one target location information based on five sliding events.

It is understood that, in the embodiment of the present application, the five sliding events may be any five sliding events of all sliding times corresponding to the sliding operation stored by the input buffer module, or may be five sliding events close to the end event. Illustratively, to ensure the accuracy of the sliding trajectory of the cursor predicted by the path prediction module, the last five detected sliding events may be selected. The embodiment of the present application is not limited to specifically selecting which five sliding events.

In one embodiment, the path prediction module may determine at least one target location information based on the five sliding events.

For example, the path prediction module may determine an ellipse equation from five pieces of position information, i.e., five coordinates, and draw the ellipse according to the ellipse equation, thereby obtaining coordinates of a center of the ellipse, and a major semi-axis a and a minor semi-axis b. The handset may then determine at least one target location based on the coordinates of the center of the ellipse, the major and minor semi-axes a, b, and the arc distance (arc distance determined according to equation 6 above). The target position information may be two-dimensional coordinates of a point predicted in the touch area.

In the embodiment of the present application, the trajectory of the cursor in the display obtained in the manner 4 by the inertia sliding is an arc.

For example, assuming that when the finger of the user performs a sliding operation on the touch area, the electronic device acquires 5 sliding events, as shown in fig. 7C, where the 5 sliding events include: input event 1, slide event 2, slide event 3, slide event 4, end event 5. The input event 1 includes location information (x1, y1) and time information T1. The slide event 2 includes position information of (x2, y2) and time information of T2. The slide event 3 includes position information of (x3, y3) and time information of T3. The slide event 4 includes position information of (x4, y4) and time information of T4. The end event 5 includes location information of (x5, y5) and time information of T5.

Assuming that the position of the input event 1 is the origin, i.e., x1 is 0 and y1 is 0, the five sliding events include all the above events. And assuming that the number of the preconfigured target positions is 3, the duration of each period is T. Then, as shown in fig. 7C, the path prediction module determines coordinates (X, Y) of the center of the ellipse according to the five position information of the input event 1, the sliding event 2, the sliding event 3, the sliding event 4, and the end event 5, and determines a major axis a and a minor axis b, and also determines an arc distance Si corresponding to each of the 3 target positions. And then determining the coordinates of 3 target positions according to the circle center coordinates, the major semi-axis a, the minor semi-axis b and the arc distance of the ellipse.

It should be noted that, in the embodiment of the present application, the path prediction module may determine at least one piece of target location information by using other manners besides the above four manners.

In addition, in the embodiment of the present application, any one of the four manners may be pre-stored in the electronic device for use by the path prediction module when determining the target position coordinate. Alternatively, all of the above four modes may be prestored in the electronic device. In this case, when the target location information needs to be determined, the path prediction module may select one manner from all pre-stored manners to determine the target location information. For example, the path prediction module may select one of all ways as the final use way. Or, the path prediction module may determine which way to select to determine the target position information by using a preset trajectory selection algorithm according to the trajectory of the actual movement of the cursor. For example, the path prediction module may determine the radian of the trajectory of the real sliding by analyzing the position information in all sliding events corresponding to the sliding operation. If the arc is less than the preset range, the path prediction module may select mode 1 or mode 3 to determine the target location information. If the arc is greater than the preset range, the path prediction module may select mode 2 or mode 3 to determine the information of the target position. The embodiment of the present application does not limit what specific manner the path prediction module determines the at least one target location information.

As can be seen from the above, in the above mode 3, compared with the

modes

1, 2 and 4, the path prediction module refers to the position information and the time information in all the sliding events corresponding to the sliding operation when predicting the information of the target position, and since there are more data comprehensively considered in the mode 3, the information of the target position predicted by the mode 3 is more reasonable, so that the trajectory of the cursor in the display moving according to the inertia is smoother.

6. The path prediction module sends at least one target location information to the input distribution module.

For example, the path prediction module may send all the target location information to the input distribution module once after determining all the target location information. Or, each time the path prediction module determines one piece of target location information, the determined target location information may be sent to the input distribution module. The method for the path prediction module to send the at least one piece of target location information is not limited herein in the embodiments of the present application.

For another example, the path prediction module may not perform any operation after determining the at least one target location information.

7. The input distribution module receives at least one piece of target position information sent by the path prediction module and executes operation according to the target position information.

In this embodiment of the application, the specific description of the operation executed by the input distribution module according to the target location information is similar to the description of the operation executed by the input distribution module according to the location information in the sliding event in step 4, and is not described herein again.

The detailed description of step 802 may refer to the related description in step 4 in fig. 6, and is not repeated herein.

803. And the electronic equipment responds to the sliding ending operation and determines at least one piece of target position information according to the acquired sliding event.

When the electronic device detects the last touch event, namely the end event, in one sliding operation, the sliding end operation is determined to be received.

And the target position information is used for representing the predicted position information of the finger on the touch area.

The specific description of step 803 may refer to the related description in step 5 in fig. 6, and is not repeated here.

804. The electronic equipment converts each target position information in the at least one target position information into second position information of the cursor in the display, and draws and displays the cursor according to each second position information.

The detailed description of step 804 may refer to the related description in step 7 in fig. 6, and is not repeated herein.

From the above, when the finger of the user stops moving in the touch area, the electronic device realizes that the control cursor continues to move for a distance according to inertia.
