The types of the mouse introduce.
1. Mechanical mouse: The photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller column reflects the displacement change of the mouse in the vertical and horizontal directions, and then controls the cursor on the screen through the processing and conversion of the computer program…
