A head tracking system continuously adjust the stereo projection to the current position of the leading viewer. Stereoscopic viewing enhances the perception of depth and the sense of space. The virtual world is presented in full scale and relates properly to the human size. Realistic interactions with virtual objects via data glove and similar devices allow for manipulation, operation, and control of virtual worlds. The convincing illusion of being fully immersed in an artificial world can be enhanced by auditory, haptic, and other non-visual technologies.
All users see the same virtual environment from their respective points of view.
The users can see each other, communicated with each other, and interact with the virtual world as a team. The boundaries are becoming blurred, but all variations of VR will be important in the future. Home pages become home spaces. However, the syntax and data structure of VRML provide an excellent tool for the modeling of three-dimensional worlds that are functional and interactive and that can, ultimately, be transferred into fully immersive viewing systems. Other VR-related technologies combine virtual and real environments.
