a new medium that enables a user to share a virtual space with remote participants.
The user is immersed in a 3D world that is transmitted from a remote site. This
medium for human interaction, enabled by digital technology, approximates the
illusion that a person is in the same physical space as others, even though they
may be thousands of miles distant. It combines the display and interaction techniques
of virtual reality with new computer-vision technologies. Thus with the aid of
this new technology, users at geographically distributed sites can collaborate
in real time in a shared, simulated, hybrid environment submerging in one another's
presence and feel as if they are sharing the same physical space.
is the ultimate synthesis of media technologies:
1.3D environment scanning,
2.projective and display technologies,
5.robotics and haptics, and powerful networking. The considerable
requirements for tele-immersion system, make it one of the most challenging net
In a tele-immersive environment
computers recognize the presence and movements of individuals and objects, track
those individuals and images, and then permit them to be projected in realistic,
multiple, geographically distributed immersive environments on stereo-immersive
surfaces. This requires sampling and resynthesis of the physical environment as
well as the users' faces and bodies, which is a new challenge that will move the
range of emerging technologies, such as scene depth extraction and warp rendering,
to the next level.
