Mouse
I opened up my mechanical mouse(the one using roller) to see how it worked. I saw that there were two orthogonally placed toothed wheels which rolled with the mouse. THe toothed wheels were placed in the path of an IR Rx/Tx.
Now I couldn't figure out how the system decided whether the mouse is moving up or down, or right or left. THe mechanism I saw doesn't seem to have provision to decide the direction?
