Input & Output Devices

1. Input

   • Mouse
     • A mouse is a standard input device. Modern mice work by a laser on the underside that senses movement and moves the on-screen pointer as needed. Older mice use a trackball, which is a little rubber ball locked in the underside of the mouse which rolls when the mice moves.
   • Smart Board
     • A projector can project an image onto a smart board so the user can interface with the computer by touching the smart board in the projected image as long as they are synced.
   • Joystick
     • A joystick is primarily used to play video games on a computer. Some people use it as an alternative to a mouse, and it can be used by disabled people with little movement.
