Mice and Trackballs

Mice and trackballs are computer pointing devices, but differ in movement: a mouse moves across a surface, while a trackball stays stationary, with a user rolling a ball (with thumb/fingers) to control the cursor, offering ergonomic benefits (less wrist strain) and saving desk space, making them great for limited areas or users seeking comfort/precision for design or gaming. Key differences include the tracking mechanism, ergonomic advantages, and space requirements, with trackballs ideal for stationary use and reduced arm movement.
