Mouse cursor pointing control method, device and system

Abstract

The embodiment of the invention discloses a mouse cursor pointing control method, device and system. The system includes a mouse cursor pointing control device, a display, a processor and a pointing device, and a camera is installed on the pointing device. The mouse cursor pointing control device includes: a coordinate frame inserting module for inserting a coordinate frame into the image frame sequence being displayed on the display, the coordinate frame includes a plurality of coordinate grids, each coordinate grid corresponds to a coordinate; the coordinate photo is received The module is used to receive the coordinate photo sent by the pointing device. The coordinate photo is the image of the coordinate grid pointed by the pointing device taken by the camera when the user points the pointing device to the display. The mouse cursor positioning module is used to locate the coordinates according to the coordinates on the coordinate photo. The coordinates corresponding to the grid determine the pointing coordinates; the coordinate sending module is used for sending the pointing coordinates to the processor, so that the processor controls to move the mouse cursor to the position corresponding to the pointing coordinates on the display.

Description

technical field [0001] The invention relates to the field of display control, in particular to a mouse cursor pointing control method, device and system. Background technique [0002] In speeches, meetings, training, etc., the lecturer often needs to use a large shared display to display the courseware, prepared materials, and results images he made. Because the speaker needs to communicate with the audience, it is inconvenient to always face the computer screen and use the mouse connected to the computer to operate, but needs to face the audience and directly point to a certain position on the large shared display to perform corresponding mouse operations and demo. For this reason, many kinds of mouse cursor pointing control devices have appeared on the market to control the position of the mouse cursor on the large-scale shared display. [0003] One of the more common ones is to use resistive touch or capacitive touch technology. The speaker can directly touch and locate...
