The ‘hardware control’-’pixel world’ mapping (2)
are the hardware components you use to "talk" to a computer. You use them to place requests, send messages (to the computer or to other people), move around in virtual worlds, or even shoot at "enemies" in some computer games. A few examples of commonly used input devices are:
- Computer keyboard
- Joystick
- Microphone
- Mouse
- Pen (some with, some without, a pad)
- Touch-sensitive screen
- Trackball
- TrackPoint
