User Interfaces

• Different from I/O.
• Look at the user - computer interface
• User sends information to the computer using
  things such as keyboards, mouse, pen, joystick,
  FSR, touch-screens, 3D Devices, Voice, Video,
• Computer presents information to the user using
  things such as displays, sound, speech, haptic,
  ...

Tomorrows Interfaces

• Many alternative interfaces emerging
• virtual realities, head-mounted displays, sound
  and speech, pen and gesture recognition,
