201: and acquiring the touch screen event to obtain event acquisition data.
The touch screen is a display screen with a touch function, and a user can realize human-computer interaction through the touch screen, for example, control an application program (for example, a game). The terminal equipment collects touch screen events to obtain event collection data, wherein the touch screen events comprise touch tracks on a touch screen.
The principle of collecting touch screen events can be seen in fig. 3a and 3 b; FIG. 3a is a schematic diagram of a touch trajectory on a touch screen, where the touch trajectory reflects a touch screen event operated by a user on the touch screen; fig. 3b is a schematic diagram of the touch trajectory in fig. 3a, and the obtained data points are event acquisition data.
Step 202: and sampling the edge value of the event acquisition data to obtain edge point data.
After the event acquisition data is obtained, edge value sampling is carried out on the event acquisition data to obtain edge point data. The implementation principle of the method can refer to fig. 3b and fig. 4, where fig. 4 is a schematic diagram of sampling the edge value of the event acquisition data of fig. 3b, the obtained data point is edge point data, and the edge point data is representative data and can well reflect the touch screen event. Therefore, compared with the event acquisition data, the obtained edge point data greatly reduces the data volume.

Wherein N is an integer greater than or equal to 3.
Step 203: and sending the edge point data to a cloud server.

Specifically, the cloud server may perform interpolation processing on the received edge point data according to a linear interpolation principle to obtain touch screen event data. For example, fig. 6 shows a schematic diagram of performing interpolation processing on edge point data, where edge point data received by the cloud server may refer to fig. 4, and touch screen event data shown in fig. 6 may be obtained by performing linear interpolation on the edge point data shown in fig. 4, so as to implement restoration of a touch screen event.

Based on the touch screen event processing method provided in the embodiment corresponding to fig. 1 and fig. 2, another embodiment of the present application provides another touch screen event processing method, which may be applied to a touch screen event processing system, such as an Android cloud game system, where a schematic structural diagram of the touch screen event processing system may be shown in fig. 7, and the touch screen event processing system may include a terminal device 701 and a cloud server 702; the cloud server 702 may include a virtual machine or a physical machine that is network-connected to the terminal device 701. In practical applications, the touch screen event processing system may include at least one terminal device 701 and a cloud server 702, for example, as shown in fig. 8, the touch screen event processing system may include three terminal devices 701, where the terminal devices 701 may be game terminals, in this embodiment, the terminal devices 701 may be smart terminal devices configured with a display screen, such as a smart phone, a tablet computer, and a notebook computer, and the display screen has a touch function, that is, the terminal devices 701 are configured with a touch screen; the cloud server 702 comprises a virtual machine or a physical machine which is in network connection with each terminal device 701, an Android operating system can run in the virtual machine or the physical machine, a virtual multi-point touch screen module can be established in the Android operating system, processed touch screen events sent by the terminal devices 701 can be processed and injected into an Android cloud game, and control over the Android cloud game is achieved. In this embodiment, an Android cloud game system is taken as an example to illustrate that the Android cloud game system includes a set of terminal equipment 701 and a virtual machine or a physical machine, which does not represent that the application is limited thereto. Referring to fig. 9, the touch screen event processing method provided by the present embodiment may include the following steps:
step 901: and the terminal equipment collects the touch screen event to obtain event collection data.
The terminal device 701 acquires a touch screen event, which includes a touch trajectory on the touch screen, and specifically, includes continuous sampling coordinate points of the touch trajectory on the touch screen, and can obtain a large amount of event acquisition data. The schematic diagram of the acquisition principle can refer to fig. 3a and 3 b.
Step 902: and the terminal equipment samples the edge value of the event acquisition data to obtain edge point data.
The terminal device 701 performs edge value sampling on a large amount of acquired event acquisition data to obtain edge point data, and thus, the edge point data obtained by edge value sampling is a sample event. The principle of edge value sampling is as follows: and searching all edge points in the edge area as sample points by using an edge sampling algorithm according to the coordinates (x, y) of the event acquisition data to obtain edge point data.
There are many ways to find the edge point in the edge area, for example, an alternative implementation is: firstly, determining all vertex data in event acquisition data, wherein the vertex data refers to data points of which the slope with the left data point is positive and the slope with the right data point is negative; then, in every two adjacent vertex data and the event acquisition data between the two vertex data, extracting the maximum value and the minimum value of every continuous N (N is an integer greater than or equal to 3) data points, and removing the intermediate value, wherein the extracted maximum value and the extracted minimum value form edge point data.
For another example, another optional implementation manner of finding the edge point may be: firstly, acquiring data points at two ends of event acquisition data to obtain a first edge point and a second edge point, wherein the two data points are used as two data points in edge point data; then, inflection point data in the event acquisition data are extracted to obtain at least one third edge point data, wherein the inflection point data refer to data points with positive and negative slopes or negative and positive slopes of the data points on the left side and the right side; and then the first edge point, the second edge point and all the obtained third edge point data form edge point data.
Specifically, for two adjacent data points, the method for calculating the slope thereof is as follows: assuming that the coordinates of the right data point are (x1, y1) and the coordinates of the left data point are (x2, y2), the slope k of the two data points is calculated as follows:
step 903: and the terminal equipment sends the edge point data to the cloud server.
After the terminal device 701 obtains the edge point data, the edge point data may be sent to the cloud server 702 through the network. In practical application, the cloud server 702 includes a virtual machine or a physical machine connected to the terminal device 701 through a network, an Android operating system may be run in the virtual machine or the physical machine, a virtual multi-point touch screen module may be established in the Android operating system, and the terminal device 701 may send edge point data to the virtual multi-point touch screen module in the cloud server 702.
Step 904: and the cloud server performs interpolation processing on the edge point data to obtain touch screen event data.
After receiving the edge point data sent by the terminal device, the cloud server 702 performs interpolation processing on the edge point data to obtain touch screen event data, where the touch screen event data can represent a touch track on a touch screen. Specifically, the cloud server may perform interpolation processing on the edge point data according to a linear interpolation principle to obtain touch screen event data, the interpolation principle may refer to fig. 4 and 6, and as can be seen by comparing fig. 6 with fig. 3a and 3b, the edge point data may be restored to the touch screen event data through the interpolation processing, and the touch screen event data is a touch screen event acquired by the terminal device.
In practical application, the virtual multi-touch screen module of the virtual machine or the physical machine running in the cloud server may receive and interpolate edge point data, and after obtaining touch screen event data, the touch screen event data is injected into an application program running on the virtual machine or the physical machine to control the application program. In this embodiment, the touch screen event data is injected into the Android cloud game, so that the Android cloud game is controlled.
