Definition§
A trackball is a stationary computer pointing device that features a ball housed in a socket. Users can manipulate the cursor on the screen by rotating the ball with their thumbs, fingers, or palms. Unlike a traditional mouse, which moves across the desktop surface, the trackball itself remains stationary while the ball inside moves.
