Computer/Computerized System Trackballs
Definition : Computer peripheral devices that consist of a small, rotatable ball (i.e., trackball) set inside a stationary mounting piece. The trackball is rotated to enter motion data into computers in order to direct the cursor on a computer screen. The trackball mountings also include left-click and right-click buttons that are used to select desktop objects or position the cursor for text entry on a computer screen, and to manipulate images, icons, or items on the screen. Computer input trackballs are used to navigate around a computer program or web page. Applications of specific computer input trackballs include data input for computers, workstations, and computerized systems, often as an integral component of computers (e.g., laptop computers) and other computerized systems.
