Abstract
With the development of information technology, multi-media teaching has been applied widely in various colleges and institutions. In the classroom teaching, the teachers must utilize the remote control device to operate the computer and use body movements. In this paper, a kind of multi-function laser remote control pointer is designed, which can be used as a mouse without power consumption and operation platform., and then teachers can shake off the shackles of the computer and remote control the computer anywhere in the classroom. In this way, teachers can present the lecture through the computer and at the same time make full use of their body language and personal charm.
