Computer presentation pointer small method
Laser pointer mouse positioning system and method; the laser pointer mouse positioning system includes a laser pointer mouse and a projector. The technical scheme of the present invention adopts a camera provided on the projector, and a corresponding mouse left and right button is provided on the Laser pointer mouse. The left control button and control button of the laser pointer. When the control button on the laser pointer mouse or the control fails, the camera is used to obtain the projected image for positioning, and the relative position on the projected image is used to identify the laser spot to obtain the mouse and mouse in the operating system The coordinates of the interface enable the corresponding operations to be performed on the interface coordinates, so as to realize the operation of the laser pointer and the mouse remote control, so that the user can obtain the precise experience of the mouse, not the distance of the mouse and the mouse, so as to facilitate the influence, teaching and presentation, etc., to achieve the laser pointer pointing What's the function.

The development of network technology has brought great convenience to people's lives. Mobile phone calls, network videos, and network phones have helped people eliminate regional barriers and realize barrier-free communication. However, the problems solved by network technology are far more than the realization of barrier-free communication. In recent years, remote application technologies such as remote video conferencing, remote teaching, remote surgery, and remote experimental guidance based on network technology have become more and more perfect. In the application technology, local visitors or instructors can intuitively communicate with on-site personnel located at the remote end. In occasions where the laser pointer needs to be delivered through a projector, in order to guide the audience's sight, the speaker often uses the laser pointer to demonstrate 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.
