The goal of ‘Computer Augmented Environments’ is to bring computational power to everyday objects with which users are already familiar, so that the user interface to this computational power becomes almost invisible. Video is a very important tool in creating Augmented Environments and recent camera-manufacturing techniques make it an economically viable proposition in the general marketplace.

VNC is an ultra-thin client system based on a simple display protocol that is platform- independent. It achieves mobile computing without requiring the user to carry any hardware.
