[0003] Especially in the field of multiple image selection, there are three common methods for simultaneously selecting multiple graphics in a scene in various graphics processing software or modules: one is to drag and drop, with the starting point and end point of the drag serving as the two diagonal vertices of a rectangular selection, to select the graphics inside or intersecting the rectangular selection; the second is to put all the graphics in the scene into a list in the form of buttons, and click different buttons in the list multiple times to select the graphics corresponding to these buttons; the third is to use keyboard shortcuts + mouse or touch to click on multiple graphics. The above three methods have their own characteristics and advantages and are widely used in traditional desktop system software. However, with the emergence of large-screen touch devices, the above three methods have certain limitations.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] With the emergence of large-screen touch devices, when operating large-screen devices at close range, the high position of the top of the screen makes it difficult to select the top area, and the large screen size requires the operator to frequently move the position to reach the designated selection area. In response to the above technical defects, the present application provides an area determination solution, which triggers the generation of an initial closed area through a first gesture instruction, and then controls the mobile control point on the initial closed area to perform inertial sliding through a second gesture instruction, thereby solving the problem of difficulty in selecting the top area on large-size touch screens. At the same time, it also avoids the operator from frequently moving during the area determination process, so as to efficiently determine the required area.

[0039] Figure 1 This is a flow chart of a region determination method provided in an embodiment of the present application. Figure 1 As shown, the area determination method includes:

[0040] S11: Acquire a first gesture instruction, and trigger generation of an initial closed area according to the first gesture instruction; wherein each vertex position of the initial closed area is provided with a movement control point.

[0041] In this embodiment, a first gesture instruction is obtained and triggered to generate an initial closed area based on the first gesture instruction; wherein, each vertex position of the initial closed area is set with a movement control point. For large touch screens, the first gesture instruction is also the "start selection" touch gesture, which triggers the generation of the initial closed area. The initial closed area can be used for multiple selection of graphic objects. The initial closed area is a closed polygonal area, and movement control points are set at each vertex position of the polygon. When the first gesture instruction is obtained, the movement control points are displayed at each vertex of the closed polygonal area.

[0042] S12: Acquire a second gesture instruction, and control the corresponding mobile control point to perform a directional slide according to the second gesture instruction.

[0043] In this embodiment, a second gesture instruction is obtained, and the corresponding mobile control point is controlled to perform a directional sliding according to the second gesture instruction. The second gesture instruction can be understood as a gesture instruction for moving the mobile control point, including the mobile control point to be moved, the movement direction, and the movement speed. In other words, the second gesture instruction is the path and speed of the operator's touch on the touch screen, and the directional sliding path and speed of the mobile control point are consistent with the second gesture instruction.

[0044] For larger touch screens, due to the limited touch screen area, it is more difficult to select the area at the top of the screen, which results in limitations in the directional sliding of the mobile control point. Therefore, the mobile control point needs to have the function of inertial sliding, which can further perform inertial sliding according to the directional sliding situation after the directional sliding. After the mobile control point of the selected area is determined to have the inertial sliding function, the operator can drag the mobile control point to a higher or farther position on the touch screen, and can use gestures to accurately control the sliding stop position of the mobile control point and fine-tune the position of the entire selection area, so that the user only needs to touch a smaller area of ​​the touch screen to complete multiple selections of areas at any position on the touch screen.

[0045] S13: Determine inertial sliding data of the mobile control point based on the second gesture instruction, and control the mobile control point to perform inertial sliding according to the inertial sliding data to obtain a candidate closed area corresponding to the initial closed area.

[0046] In this embodiment, the inertial sliding data of the mobile control point is first determined based on the second gesture instruction. Then, the mobile control point is controlled to slide inertially according to the inertially sliding data to obtain a candidate closed area corresponding to the initial closed area. Furthermore, when the third gesture instruction is obtained while the mobile control point is controlled to slide inertially according to the inertially sliding data, the mobile control point is controlled to stop inertially sliding according to the third gesture instruction and the stop position of the mobile control point is determined to obtain a candidate closed area corresponding to the initial closed area. The third gesture instruction is also known as the "stop control point sliding" touch gesture, which is used to stop all mobile control points that are inertially sliding.

[0047] In this embodiment, after obtaining a candidate closed area corresponding to the initial closed area, it is necessary to determine whether the candidate closed area meets the target requirements. If so, the area is confirmed to terminate the selection operation. Specifically, a fourth gesture instruction is obtained, and the candidate closed area is determined as the target closed area based on the fourth gesture instruction. The fourth gesture instruction, also known as the "Confirm Selection" touch gesture, is used to confirm the current selected area as the final selected area. It is not difficult to understand that for the operation of selecting multiple graphical objects based on the selection area, all graphical objects within the target closed area can be further extracted from the target closed area. If the requirements are not met, the candidate closed area is hidden to abandon the selection, thus terminating the selection operation. Specifically, a fifth gesture instruction is obtained, and the candidate closed area is hidden based on the fifth gesture instruction. The fifth gesture instruction, also known as the "Abandon Selection" touch gesture, is used to hide the current selected area. In summary, the touch gestures used in the above-mentioned area determination process mainly include six basic gestures: "Start Selection," "Move Control Point," "Move Selection Area," "Stop Sliding Control Point," "Confirm Selection," and "Abandon Selection." The commands representing the above touch gestures can be defined as: moving a control point with one or more fingers, moving a selection area with one or more fingers, continuously tapping with multiple fingers to start or cancel a selection, and stopping a control point slide with multiple fingers. It should be noted that the above definitions can be customized based on actual business needs and are not limited in this embodiment of the application.

[0048] It can be seen that the embodiment of the present application first obtains a first gesture instruction, and triggers the generation of an initial closed area according to the first gesture instruction; wherein, each vertex position of the initial closed area is set with a mobile control point; then obtains a second gesture instruction, and controls the corresponding mobile control point to perform a directional sliding according to the second gesture instruction; finally, based on the second gesture instruction, determines the inertial sliding data of the mobile control point, and controls the mobile control point to perform inertial sliding according to the inertial sliding data, so as to obtain a candidate closed area corresponding to the initial closed area. The embodiment of the present application generates an initial closed area by triggering the first gesture instruction, and then controls the mobile control point on the initial closed area to perform inertial sliding by the second gesture instruction, thereby solving the problem of difficulty in selecting the top area on a large-size touch screen, while also avoiding the operator from frequently moving during the area determination process, so as to efficiently determine the required area.

[0049] Figure 2 This is a flow chart of a specific area determination method provided in the embodiment of this application. Figure 2 As shown, the area determination method includes:

[0050] S21: Acquire a first gesture instruction, and trigger generation of an initial closed area with a rectangular outline according to the first gesture instruction; wherein the movement control points are set at the four vertex positions of the initial closed area.

[0051] S22: Acquire a second gesture instruction, and control the corresponding mobile control point to perform a directional slide according to the second gesture instruction.

[0052] In this embodiment, the first gesture instruction is first obtained, and then the generation of an initial closed area with a rectangular shape outline is triggered according to the first gesture instruction; wherein, the mobile control point is set at the four vertex positions of the initial closed area. It is not difficult to understand that the four vertex positions of the initial closed area with a rectangular shape outline are respectively provided with a mobile control point. After the first gesture instruction is obtained, a small rectangular selection area is given at the position where the gesture is triggered and the mobile control point is displayed at the four vertices of the rectangle. Then the second gesture instruction is obtained, and the corresponding mobile control point is controlled to slide in a direction according to the second gesture instruction, that is, the mobile control point on the fixed point of the rectangular initial closed area is controlled to move in a direction. In this embodiment, for the specific process of the above-mentioned steps S21 and S22, please refer to the corresponding content disclosed in the aforementioned embodiment, and no further details will be given here.

[0053] S23: Determine directional sliding data of the mobile control point corresponding to the second gesture instruction, and calculate inertial sliding data of the mobile control point using an inertial sliding algorithm according to the directional sliding data; wherein the inertial sliding data includes a speed change curve.

[0054] S24: Determine whether the mobile control point performs inertial sliding according to the directional sliding data. If so, control the mobile control point to perform inertial sliding according to the speed change curve to obtain a candidate closed area with a rectangular shape outline corresponding to the initial closed area.

[0055] In this embodiment, during the directional sliding of the mobile control point, directional sliding data of the mobile control point corresponding to the second gesture instruction is determined, and inertial sliding data of the mobile control point is calculated using an inertial sliding algorithm based on the directional sliding data; wherein the inertial sliding data includes a velocity change curve. Specifically, during the operator's touch movement of the mobile control point, the algorithm continuously collects the velocity of the mobile control point in the X and Y directions and updates the velocity of the control point in the X and Y directions using a weighted method (the last recorded velocity and the most recently collected velocity are multiplied by their respective weights and summed). After the touch movement of the mobile control point ends, i.e., the directional sliding ends, the directional sliding data is further used to determine whether the mobile control point has performed inertial sliding. If so, the mobile control point is controlled to perform inertial sliding based on the velocity change curve to obtain a candidate closed area with a rectangular shape corresponding to the initial closed area. Specifically, whether the mobile touch point has performed inertial sliding and the velocity change curve used for inertial sliding are determined based on the duration of the touch movement and the most recent velocity. If the mobile control point touches the edge of the touch screen during inertial sliding, it is adsorbed to the edge of the touch screen.

[0056] Figure 3 It is shown that when the mobile control point TR at the upper right corner of the initial closed area with a rectangular shape outline is moved to a new position along the dotted arrow, the final closed area with a rectangular shape outline is obtained. It should be noted that for the rectangular selection area, when the mobile control point of one vertex moves, the mobile control points of other vertices change position as the position of the moved vertex changes, that is, the closed area is always kept as a rectangle. However, for the polygonal area based on the larger mobile control point in the aforementioned embodiment, when the mobile control point of one vertex moves, the mobile control points of other vertices will not change position as the position of the moved vertex changes. In addition, in order to improve compatibility, the gestures of "adding a vertex" and "deleting a vertex" can also be added in the embodiment of the present application.

[0057] It can be seen that the embodiment of the present application uses a rectangular selection box as the form of the selection area, the selection area supports touch dragging, and mobile control points that support touch movement are added to the four vertices of the rectangular selection area. The range of the rectangular selection box can be changed by moving the control points. The mobile control points can slide inertially at the end of the touch movement, which solves the problem of difficult touch selection at a higher position on a large-size touch screen, and can also alleviate the problem of frequent movement required by the operator when selecting a larger range, further facilitating users to quickly perform graphic multiple selection operations on a large-size touch screen.
