detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In one embodiment, the method of adjusting the position of the object is applied to a touch device of a large screen, particularly a touch integrated machine. As shown in FIG. 1, a method for adjusting an object position includes the following steps:

S102: Detect whether there is a drag operation on the object.

An object is an application installed on a touch device or a file and folder stored on a touch device. The drag operation on the object refers to the user selecting and dragging by the touch operation. In a specific implementation manner, when the object is pressed for more than a preset time, the object is selected and slid on the touch screen to implement the drag operation.

S104: When a drag operation on the object is detected, generate a first touch event, and collect touch information of the first touch event.

When the pressing object exceeds the preset time and slides on the touch device, a drag operation on the object is detected to generate a first touch event.

S106: Generate an N+1th touch event every Nth preset interval time, and collect touch information of the touch event.

Specifically, a second touch event is generated at a first preset interval time, a third touch event is generated at a second preset interval time, and so on, and a Nth is generated at the Nth preset interval time. +1 touch event and collect touch information of the touch event. It can be understood that the preset interval time is counted from the time when the first touch event is generated.

The preset interval time needs to be relatively short, so that in a continuous touch event, the sliding of the touch point forms a continuous sliding track on the touch screen. In a specific embodiment, the preset interval time is 10 milliseconds, and 100 touch events are generated within 1 second.

The touch information includes the number of touch points acting on the touch screen. In a touch event, the number of touch points on the touch screen may change, for example, the number of touch points is increased relative to the last touch event, for example, The number of touch points is reduced relative to the last touch event.

S108: Calculate a displacement of the object in the corresponding touch event according to the touch information of the touch event.

It can be understood that the displacement of the object in the (N+1)th touch event refers to the Nth touch event. The moving distance of the object, that is, the moving distance of the object in the preset time interval corresponding to the touch event. The displacement of the object in a touch event is calculated based on the touch information in the touch event. The number of touch points is positively related to the displacement of the object. In one embodiment, when the number of touch points is increased relative to the last touch event, the displacement of the object in the touch event is relatively increased. In one embodiment, when the number of touch points is reduced relative to the last touch event, the displacement of the object in the touch event is relatively reduced.

S110: Move the object to the corresponding position of the displacement of the object in the (N+1)th touch event.

In this embodiment, the object is moved to the corresponding position of the displacement of the object in the (N+1)th touch event, and the displacement of the object can be displayed on the touch device in real time according to the operation of the user, and the user selects the object and drags the object. During the process, the movement of the object can be visually observed to facilitate adjusting the number of touch points according to the distance of the moving position of the object in the current touch event from the target position. It can be understood that since the number of touch points is positively correlated with the displacement of the object, when the object is dragged on the touch screen by using multiple touch points, the object is not necessarily directly below the touch point.

The method for adjusting the position of the object, when detecting a drag operation on the object in the touch device, generates a touch event and collects touch information of each touch event, where the touch information includes the number of touch points acting on the touch screen, and the touch The number of points is positively correlated with the displacement of the object, and the object is moved to the corresponding position of the displacement of the object in the (N+1)th touch event. Since the number of touch points is positively correlated with the displacement of the object, the displacement of the object in unit time can be flexibly adjusted by increasing or decreasing the number of touch points, thereby flexibly adjusting the drag speed of the object. By increasing the number of touch points of the object dragged on the touch screen, it is possible to move the object to a distant position on the screen without sliding the object on the touch screen for a long distance, and the user is convenient to operate, and the method is especially suitable for the object of the large screen. Adjustment of position.

In an embodiment, as shown in FIG. 2, after step S110, the method further includes the steps of:

S112: Detect whether the drag operation ends. If yes, go to step S114, if no, go back to step S106.

S114: The displacement of the object during the dragging process is the sum of the displacements of the objects in each touch event.

The detection of whether the drag operation ends can be achieved by detecting whether there is a touch operation in the touch device, that is, detecting whether the touch point leaves the touch device, and when the touch point is detected to leave the touch device, the drag operation ends. When the end of the drag operation is detected, the displacement of the object in the N+1 touch event is relative The moving distance of the object in the Nth touch event, the displacement of the object during the dragging process can be obtained by calculating the sum of the displacements of the objects in each touch event. The displacement of the object during the drag is the sum of the displacements of the objects in each touch event.

In a specific implementation, the user needs to move the object located in the lower left corner of the screen to the upper right corner of the screen. After selecting the object, the user uses five fingers to drag on the screen, and in one touch event, the touch point is detected. The number of touch points is positively related to the displacement of the object. In the corresponding touch event, the more the number of touch points, the larger the displacement of the object. Therefore, multiple fingers are used to generate multiple touches. Point, the object can be moved to the vicinity of the target position at a faster speed. And, the object moves as the user drags on the touch screen, and the user intuitively observes the distance of the object from the target position. When the object moves closer to the target position, the user can reduce the number of sliding touch points, for example, using one finger to continue dragging on the touch screen. In the corresponding touch event, the number of touch points detected is one. Since the number of touch points is positively correlated with the displacement of the object, the number of touch points is reduced, the displacement of the object is reduced, and the movement of the object is relatively The speed is slowed down, and the user observes the position of the object during the movement. When moving to the target position, the touch point is released and the touch device is released, so that the position of the object is adjusted to the target position.

It can be understood that since the number of touch points is positively correlated with the displacement of the object, the more the number of touch points, the larger the displacement of the object per unit time, and therefore, the faster the object moves at unit time, therefore, the touch The number of points is positively related to the moving speed of the object.

In another embodiment, step S108 specifically includes the following steps 1 and 2:

Step 1: Calculate the displacement of all touch points in the corresponding touch event according to the touch information of the touch event.

Step 2: Calculate the sum of the displacements of all the touch points in the corresponding touch event. The displacement of the object in one touch event is the sum of the displacements of all the touch points in the touch event.

For the (N+1)th touch event, the displacement of the object in the (N+1)th touch event refers to the moving distance of the object relative to the Nth touch event. The displacement of an object in a touch event is the sum of the displacements of all touch points in the touch event.

Specifically, the touch information further includes a current coordinate of each touch point and a coordinate of each touch point in a previous touch event, and the coordinates corresponding to each touch point may be determined according to the touch point ID (Identity). set. During a continuous sliding process, the touch point ID corresponding to the touch point is constant, and the current coordinates of each touch point and the coordinates of each touch point in the previous touch event can be tracked according to the touch point ID. Calculating the displacement of all the touch points in the touch event according to the touch information of the touch event, specifically, calculating each touch point according to the number of touch points, the current coordinates of each touch point, and the coordinates of the previous touch event. The displacement in the corresponding touch event.

In a continuous touch event, the touch point forms a sliding track on the touch screen, and the touch information includes the current coordinates of each touch point and the coordinates of each touch point in the previous touch event. Calculating the distance that the touch point moves in the touch event according to the current coordinate of each touch point and the coordinates of the previous touch event, that is, the displacement of the touch point in the touch event. The displacement of the object in one touch event is the sum of the displacements of all touch points in the touch event. For example, in the Nth touch event, the user uses five fingers, and in the touch event, the displacement of the object is the sum of the displacements of the five touch points on the screen. In the N+1th touch event, the user reduces the number of touch points, and uses one finger. Since the touch point continuously slides on the touch screen, the touch point used in the N+1th touch event is acquired. The coordinates of the touch point used in the (N+1)th touch event are calculated by the coordinates in the Nth touch event and the current coordinates in the (N+1)th touch event. For another example, in the Nth touch event, the user uses one finger to generate a touch point, and in the touch event, the displacement of the object is the displacement of the touch point on the screen.

In another embodiment, step S108 includes the following steps 1 to 3:

Step 1: Obtain the number of touch points acting on the touch screen in the touch event, and determine the displacement ratio corresponding to the number of touch points.

Step 2: Calculate the displacement of any one of the corresponding touch events according to the touch information of the touch event.

Step 3: Calculate the product of the displacement of the touch point and the displacement ratio. The displacement of the object in a touch event is the product of the displacement of the touch point and the displacement ratio in the touch event.

In this embodiment. Preset the proportion of the displacement corresponding to the number of touch points in a touch event. The displacement ratio is the ratio of the displacement of a single touch point to the displacement of the object in a touch event. The displacement of each touch point in a touch event is the same. In order to facilitate the calculation, in a specific implementation manner, by acquiring the touch point ID corresponding to the touch point of the selected object, by tracking the touch point ID, The displacement of the touch point in each touch event. When the touch point of the selected object is released during the sliding process, the displacement of any touch point ID is taken to calculate the displacement of a single touch point in one touch event. The displacement ratio corresponding to the number of touch points can be set according to the size of the touch screen of the touch device. For example, the larger the touch screen, the larger the displacement ratio of the number of touch points. In a specific implementation manner, in one touch event, the displacement ratio corresponding to the number of touch points is 1:3, and in the touch event, the displacement of the object is the displacement of the touch point in the touch event. 3 times.

In this embodiment, the displacement of the object is adjusted according to the displacement of the touch point according to the displacement ratio, and by adjusting the displacement ratio, the adjustment of the object position of the oversized screen can be realized.

Next, a method of adjusting the position of the object will be described with reference to a specific embodiment.

As shown in FIG. 3, when the user presses the object 10 on the touch screen for a preset time, the object 10 is selected and dragged. The object 10 is located at the lower left corner of the touch screen, and the user needs to adjust the object 10 to the target position 20, the target position 20, and the target position 20 is located at the upper right corner of the touch screen.

As shown in FIG. 4, the user selects the touch screen to drag the object to the target position 20 during the sliding process, and increases the number of touch points, for example, using five fingers. The number of touch points is positively related to the displacement of the object. More specifically, in one touch event, the displacement of the object is the sum of the displacements of all the touch points in the touch event. Therefore, the more the number of touch points, the shorter the distance the hand slides on the touch screen, the shorter the time, the object can be dragged to a greater distance. It can be understood that, since the displacement of the object is the sum of the displacements of all the touch points in the touch event in one touch event, when the object is dragged on the touch screen by using multiple touch points, the object 10 is not at the touch point. Just below.

As shown in FIG. 5, when the drag object 10 is near the target position 20, the number of dragging touch points can be reduced to one. In the corresponding touch event, the displacement of the object is the displacement of one touch point in the touch event. Thus, the displacement speed of the object is lowered, and the user can controlably drag the object to the target position 20.

By adopting the above-mentioned object position adjustment method, the user's touch point can be adjusted from the initial position to the target position without sliding to the target position. And during the adjustment process, the drag speed of the object is controllable.

Since the number of touch points is positively correlated with the displacement of the object, the displacement of the object in unit time can be flexibly adjusted by increasing or decreasing the number of touch points, thereby flexibly adjusting the drag speed of the object. By increasing the number of touch points of the object dragged on the touch screen, it is possible to move the object to a distant position on the screen without sliding the object on the touch screen for a long distance, and the user is convenient to operate, and the method is especially suitable for the object of the large screen. Adjustment of position.

In one embodiment, when the drag operation ends, the displacement of the object during the drag is the sum of the displacements of the objects in each touch event.

The detection of whether the drag operation ends can be achieved by detecting whether there is a touch operation in the touch device, that is, detecting whether the touch point leaves the touch device, and when the touch point is detected to leave the touch device, the drag operation ends. When the end of the drag operation is detected, since the displacement of the object in the (N+1)th touch event is relative to the moving distance of the object in the Nth touch event, the object is dragged by calculating the sum of the displacements of the objects in each touch event. The displacement in the process. The displacement of the object during the drag is the sum of the displacements of the objects in each touch event.
