Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
As shown in fig. 1, the embodiment provides a cursor display method based on a remote desktop, which can meet the higher requirements of controlling cloud games or other cloud applications on various delay data and fluency by using a remote control technology, so that the delay in mouse control is lower, the mouse movement operation is better and fluency, and further the cloud games or other cloud applications achieve a localized experience effect.
The cursor display method based on the remote desktop comprises the following steps:
s1: the client captures a relative displacement value of the system mouse movement and sends the relative displacement value to a remote server providing the remote desktop so that the remote server can execute corresponding mouse movement according to the relative displacement value;
specifically, the client of the user captures system mouse movement operation data through the operating system api (e.g., the web application uses the JS api). The capture mode of the system mouse movement operation data comprises the following steps: event-triggered acquisition mode, timed polling acquisition mode, etc., for example: and when a reliable protocol is adopted to transmit data, an event trigger acquisition mode is adopted, and when an unreliable protocol is adopted, a timing polling acquisition mode is adopted. The system mouse movement operation data at least comprises relative displacement values of mouse movement. And establishing a coordinate system according to the system resolution. When the system mouse moves, the relative displacement value (m, n) of the current position of the mouse compared with the previous position is calculated according to the coordinate system.
S2: the remote server receives the relative displacement value of the mouse movement sent by the client displaying the remote desktop, and executes the corresponding mouse movement operation according to the relative displacement value;
specifically, when the remote server receives the relative displacement value (m, n), according to the resolution of the remote desktop window displayed on the client and the resolution of the remote server desktop, the relative displacement value (m, n) is converted into the corresponding displacement of the mouse movement event on the client on the remote server, and the corresponding operation is executed immediately. For example: if the resolution of the client window is a × b and the resolution of the remote server desktop is c × d, the relative displacement value of the remote server is (c/a × m, d/b × n), and at this time, the mouse of the remote server moves according to (c/a × m, d/b × n), so as to execute the mouse moving operation.
S3: the remote server captures a mouse of the remote server, and sends the proportion data of the absolute coordinates of the mouse after movement relative to the screen resolution of the remote server to the client;
specifically, after the remote server executes the mouse moving operation, the mare captures mouse image data at regular time through a graphic operation instruction of an operating system, obtains absolute coordinates (k, l) of the remote server mouse through a hook, calculates proportion data (k/c, l/d) of the remote server mouse relative to the screen resolution of the remote server, and synchronously sends the proportion data to the client. Alternatively, the sending frequency of the proportional data from the remote server to the client may be capturing and sending when new mouse movement data is generated, or sending the last captured cursor data to the client according to a predetermined frequency before new data is generated.
S4: the method comprises the steps that a client receives proportion data of absolute coordinates of a mouse after the remote server moves, wherein the proportion data is provided by the remote server and is relative to the screen resolution of the remote server;
s5: and the client draws the moved cursor at the corresponding position of the remote desktop window on the client according to the proportion data and the position and the size of the remote desktop window displayed by the client.
Specifically, after receiving mouse data (mouse image data, proportional data) sent by a remote server, a client confirms the position of a window at a certain vertex (x, y) of a display window of user local equipment by a remote desktop according to the position and the size of the window of a remote desktop displayed by the current client, and determines the size of the window as an origin according to the transverse size and the longitudinal size of the window, when the remote desktop window is in a full screen, the system resolution is the resolution of the remote desktop window, the received absolute coordinates of the mouse of the remote server are mapped relative to the proportional data of the screen resolution of the remote server, and the received mouse image data are processed differently according to the pushing mode of different types of mice, so that the mouse of the remote server can be positioned at the corresponding position (k/c a, l/d b) is drawn so that the client cursor is consistent with the remote server mouse.
In addition, for different clients, such as a computer application client and a web page client, before drawing and displaying a cursor, a local cursor needs to be hidden; for mobile app and h5 clients, since there is no local cursor, the rendering and display process can be done directly when cursor data is received.
