For example, a mortal might be a student in the environment whereas a deity may be a teacher who possesses capabilities that are not provided to the student, such as the ability to alter their scale to alter their viewpoint on the scene. Perspectives that occur from design ideas maturing over time in a system capable of sustaining a sense of temporal continuity. That is, the environment persists and evolves over time as new ideas are explored, or old ideas are reused toward the solution of new problems. Ideally collaborators may synchronously and asynchronously enter the environment to perform design work whenever inspiration strikes them. Its room-sized structure allows for multiple users to move around freely, both physically and virtually surrounded by vivid displays.
Interaction is performed mainly with the use of a wand.
The entire scene hierarchy can be saved at any time and trivially converted to VRML for general distribution over the World Wide Web. OpenInventor and the CAVE library are portable to other platforms. Through VR we are able to address this problem by providing co-presence that uses avatars and natural navigation in the environment. An avatar is a persona that each participant dons to establish a representation in the virtual environment. Participants communicate with audio and video over an ATM network using the ImmersaDesk Another feature, important in collaborative work, is support for verbal communication, and to a lesser degree, video communication.
