New Optical Mouse
Recently I've bought a new optical TEAC mouse for my notebook. I have had my old one for two years I guess but not sure. Anyway the new mouse looks pretty enough:-)
Do you know that each optical mouse has a small camera inside allowing to take more than a thousand snapshot pictures every second? A fitted light-emitting diode provides light underneath the mouse helps to highlight slight differences in the surface underneath. This differs from older-technology mice, in which a round ball rolled against a mouse pad to indicate movement.
As regards wireless technologies there are two types of mouse - infrared (IR) based on optical principle and radio frequency (RF) based on wave principle.
