Problems solved by technology
[0004] It can be seen that at present, when the position of the projection point of the remote control device on the screen of the display device is inconsistent with the position of the cursor on the screen of the display device, the operation process of calibrating the projection point and the position of the cursor is cumbersome and inefficient. When the position of the projected point on the screen is inconsistent with the position of the cursor on the screen of the display device, the accuracy of controlling the cursor movement of the display device through the remote control device is low

Embodiment Construction
[0052] It should be noted that the present invention uses a step number (alphanumeric number) to refer to certain specific method steps, only for the purpose of describing convenience and conciseness, and in no way to limit the order of these method steps with letters or numbers. Those skilled in the art will be able to understand that the order of the relevant method steps, should be determined by the technology itself, should not be unduly limited by the presence of step numbers.
[0053] Figure 1 is a flowchart of an embodiment of the display device cursor control method of the present invention, the method comprising the following steps.
[0054] Step S100, receiving the mobile instructions sent by the remote control device, according to the mobile instructions the projection point of the remote control device in the display device screen to the preset initial position.
[0055]The display device receives the mobile instructions sent by the remote control device, wherein th...

The present invention provides a display device cursor control method, device, system and storage medium, wherein the method includes: moving the projection point of the remote control device on the display device screen to the initial position; The cursor moves to the initial position; according to the control mode of the remote control device to control the cursor, the moving time during the movement of the remote control device is obtained, and according to the control mode of the cursor and the position data of the remote control device, the moving speed of the cursor is calculated; and according to the corresponding moving speed Direction, moving speed and moving time get the moving distance and the initial coordinates of the initial position to determine the end point coordinates of the corresponding end position of the cursor; convert the end point coordinates into the system coordinates in the coordinate system of the display device corresponding to the operating system, and control the cursor to move to the system coordinates . The invention simplifies the calibration process of the projection point and the cursor position, and improves the accuracy of controlling the cursor of the display device through the remote control device.
Description
Technical field [0001] The present invention relates to the field of computer technology, specifically to a display device cursor control method, apparatus, system and storage medium. Background [0002] With the popularity of intelligent interactive large screen, smart TV and other display devices, touch technology has also been updated and advanced, there are already a variety of remote control devices on the market can achieve long-distance air-distance touch operation smart TV, interactive large screen and other display devices, but the positioning of such remote control equipment needs to correct the cursor position of the display device. The remote control device controls the cursor movement in the screen of the display device through physical actions such as turning, panning, etc. Due to the different spatial positions of the remote control device when it is started, the projection point of the remote control device in the display device screen (the remote control device ...
