Inition present us a exciting new technology that allows full-body, unencumbered interaction within a virtual environment, enabling the user to interact using nothing more than the movements of his/her body. This sort of interaction relies on digital cameras interfaced to the PC to pick up motion.

Using high-end image-processing techniques (only recently possbile on PCs), the images from the camera are converted into useful data on how a person is moving. The captured video image of the user is shown on a screen (anything from a CRT monitor to a large projected display) embedded within the interactive environment (this is sometimes called ‘projected-reality’). Not requiring the user to don a headset, gloves or tracking device, interactions using this technology open up many new possibilities for bringing interactive virtual worlds into a public setting.
