What is the connection between a mouse and a laser pointer?
Laser pointer mouse positioning system and method; The laser pointer mouse positioning system includes a laser pointer mouse and a projector. The technical solution of the present invention adopts a camera provided on the projector, and a laser pointer mouse is provided with controls corresponding to the left and right buttons of the mouse Left button and control right button. When the control left button or control right button on the laser pointer is pressed, the projected image is obtained through the camera for positioning, and the relative position of the laser spot on the projected image is recognized to obtain the mouse cursor position in the operating system. The coordinates enable the operating system to perform corresponding operations at the coordinates, thereby realizing the operation of laser pointer and mouse remote control, allowing users to obtain an intuitive and accurate operation experience, and is not affected by the distance of the laser pointer and mouse, so as to facilitate teaching, speech, etc., to achieve laser pointer The function of the pen mouse pointer.

In situations where a projector needs to be used for speech, in order to guide the audience’s sight, the speaker often uses a high power laser pointer to indicate the content of the speech on the projection screen to enhance the effect of the speech. However, because traditional laser pointers only have limited functions such as laser emission and page turning, other operations still have to be completed with a mouse; therefore, the use of traditional laser pointers will still cause a lot of inconvenience to the speaker and affect the fluency of the speech. Large-screen projections are becoming more and more widely used in multimedia teaching, lectures, remote meetings and other activities. In order to obtain a good presentation effect, the speaker usually stands next to the projection screen, and uses the laser pointer in his hand to project the spot on the screen to guide the audience to the key content points. Using existing laser pointers, there are two drawbacks: 1) The audience participating in the synchronized remote conference cannot see the laser pointer's spot, and is not clear about the position of the speaker currently explaining; 2) The laser pointer used by the speaker usually does not have a mouse. Operation function, in order to demonstrate the mouse operation, you must return to the computer to operate the mouse.
