trackball mouse
Rolling sphere controller
A trackball mouse is a pointing device where you move the cursor by rolling a ball with your fingers or palm rather than sliding the whole device across a surface.
The ball sits in a socket, typically on top or to the side.
Trackballs require less desk space and can reduce wrist strain, making them popular for ergonomic setups and precision work like graphic design.
