Technical principle of wireless laser pointer

With the continuous development and progress of computer technology, the mouse as a common component of the computer has been upgraded from a traditional mechanical mouse to an optical mouse on the one hand, and on the other hand, it has been upgraded from a wired mouse to a wireless mouse. Because the wireless optical mouse has the advantages of not needing to connect to the host through a signal line, easy to use, accurate positioning, etc., more and more users begin to choose the wireless optical mouse. However, all current mice, including wireless optical mice, only have the function of a mouse. The existing mouse and laser pointer are two independent products. The mouse does not have the function of a laser pointer, and the laser pointer does not have the function of a mouse. There is no product that can have both functions.
