Trackball

A trackball is a computer input device that allows users to control the cursor on a screen by rotating a ball with their fingers or thumb, offering an alternative to traditional mice. As a precise and ergonomic pointing device, trackballs are particularly relevant to the tech community for their potential to improve user experience and reduce the risk of repetitive strain injuries, making them a popular choice among gamers, graphic designers, and individuals with mobility or dexterity limitations.
