PROJECT GOALS
• Teleimmersive multi-user system for high-bandwidth environments
like Internet 2.
• Augment reality by simultaneously interacting with virtual,
real objects and models while supporting object interposition.
• Unobstructed 3D face-to-face capture and display to support
interaction and fully mobile representations of users in space
relative to other participants and objects.
DESCRIPTION
The Teleportal room allows single or multiple users to enter
a room sized-display and use a broadband telecommunication link
to engage in face-to-face interaction with other remote users
in a 3D, augmented reality environment.
Wearing a headset that includes a projective display and stereo
video cameras, the system will allow all participants to (a) view
3D, stereoscopic, video-based images of the face of all remote
participants, (b) view unobstructed the local participants, and
(c) view a room that blends physical with virtual objects that
can be manipulated.
In the preferred embodiment of the system, multiple local and
remote users can interact in a room-sized space draped in a fine-grained
retro-reflective fabric. A tracker, composed of body worn markers,
is used to record the position of the users.
