Both Trackball and Touchscreen are types of pointing devices. A pointing device allows a user to interact with a computer interface by controlling a cursor or pointing to objects on the screen.
– A trackball is an input device used to enter motion data into computers or other electronic devices. It functions like an upside-down mouse; the user rolls a ball to move the cursor.
– A touchscreen is a display screen that can detect the presence and location of a touch within the display area, typically by a finger or stylus.
– Other common pointing devices include the mouse, touchpad, pointing stick, joystick, and graphics tablet.
