Sensing Technology
Mice can be Optical or Mechanical.
Mechanical Mice have a ball made from rough rubbery material. Rotation of that effects sensors which are perpendicular to each other. So the motion of ball along two axes is detected as well as reflected as motion of pointer on screen.
Optical Mice can detect movement with no moving parts such as a ball. The typical optical Mouse used to have a pair of LEDs (Light Emitting Diodes) and photo-detectors in every axis and its own Mousepad on that it is slided. However because of maintenance needs of Mousepad, this wasn't very successful. Lately optical Mice have made a comeback because they can now operate without a Mouse pad.
