Because each wand can be distinguished by the system as a separate input device, each guest can have their own consistent identity and personality in the computer-generated world. And since the interface is the room itself, guests can interact not only with the computer-generated world, but with each other as well. Both sound and image are highly spatial. Stereoscopic images are produced by a pair of video projectors, and localized sounds emanating from each of the objects are reproduced using a quadrophonic system. So far,the Hotel has handled between one and five guests at a time.
Guests can scan any bar code within reach at any time.
The projected environment consists of a number of computer-generated objects, each one corresponding to a different guest. These objects are brought into being by scanning unique bar codes that are printed on white cubes that are dispersed throughout the room. Once brought into existence, objects exist as semi-autonomous agents that are only partially under the control of their human collaborators. They also respond to other objects, and to their environment. They emit a variety of sounds in the course of their actions and interactions.
