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.

Examples

  1. Logitech Trackman Marble: This trackball is known for its ergonomic design and easy-to-use features, aimed at providing comfort during prolonged usage.
  2. Kensington Expert Mouse: Popular for its large ball and precision, making it suitable for graphic design and detailed work.
  3. Kensington Orbit Trackball: Equipped with a scroll ring and ambidextrous design, it offers versatility and ease of navigation for notebook computer users.
