Google is the best place to find it, i.e.
http://computer.howstuffworks.com/mouse.htm
is one of them... read them through, you can also search for radio wave etc.
if I have room with 10 computers in it and I run wireless mice on each one, presumably they don't interfere with each other? why?
also where is the transmitter? is it in the computer or the mouse?
and is there a limit on the range? presumably the optical mice have to be in line of sight, whereas the radio ones dont? What happens when they are out of this range?
can anyone point me to a website that could explain the technical aspects of this operation? explaining the technicals of how the radio/wireless/recognition system actually works?
