This section gives details on the USB mouse (optical).
Regarding the optical mouse
The optical mouse has an optical sensor located on the bottom. The sensor on the bottom of the mouse
detects the shadows in the optical beam output from the bottom of the mouse when it is used on a desk,
which causes the on-screen mouse pointer to move.
The optical mouse works not only on top of a desk, but you can also use it on top of paper, however,
it may not move properly if used on the following surfaces.
● A reflective surface such as a mirror or glass
● A glossy surface
●
A surface with alternating light and dark areas such as stripes or a pattern (such as wood grain)
●
An item printed in halftones, or a repetition of a similar pattern
The mouse movement is recognized even if the optical sensor is not touching the desk so a mouse pad
is not required, but the mouse itself is touching the desk so it is recommended that you use a mouse
pad on a desk that could be scratched easily.
It is recommended that you use a bright solid color mouse pad if you are going to use a mouse pad.
There are mouse pads on the market that are for an optical mouse.
