A mechanical mouse consists of two rollers in contact with a ball located inside an object the user can slide over a flat surface. The rollers are at 90 degrees to each other and connected to slotted wheels. As the mouse slides, the ball rotates the rollers, causing the slots in their attached wheels to interrupt infrared light sources, thus giving the computer a way to interpret the motion and move the cursor accordingly.
