The manufacturing principle of remote control laser pointer
In a usual meeting, the projector plays an increasingly important role, and the user will project the image on the computer for the people attending the meeting to watch. At the meeting, users usually use the existing laser pointer to indicate the key points that should be paid attention to by others. At the same time, the existing laser pointer has functions such as page up and down, which provides us with convenience. However, if you want to achieve more control over the displayed screen, such as clicking a specific point in the screen or implementing functions such as drag and drop, writing, etc., you have to use the mouse and keyboard again. Therefore, if there is a laser pointer that can remotely control the projector, these problems will be solved to a great extent.
