 Introduction

Tele-immersion may be the next major
development in information technology. Using
tele-immersion, you can visit an individual across
the world without stepping a foot outside.

Tele-Immersion is a technology by which you’ll
interact instantly with your friend on the other
side of the globe through a simulated
holographic environment.

This technology, which will come along with
Internet2, will change the way we work, study
and get medical help.

Tele-Immersion (TI) is defined as the integration
of audio and video conferencing, via imagebased modeling, with collaborative virtual
reality

New medium that enables a user to share a
virtual space with remote participants.


Immersion in general means a psycho-physical
condition which gives the user the illusion that
he acts in an environment which is different
from the real one.

It combines the display and interaction
techniques of virtual reality with new computervision technologies.

In1965 Ivan Sutherland, proposed
the concept of the “Ultimate
Display”.

“Ultimate Display” described a
graphics display that would
enable the user to experience a
completely computer rendered
environment.

This was the beginning of active
research into modern graphics,
virtual reality and its forerunner tele-immersion, which was to
come later.
Ivan Sutherland

The tele-immersion concept was for the first
time demonstrated in May 2000 when three
geographically distributed tele-immersion sites
were virtually interconnected.

These sites were:



Advanced Network & Services (Armonk, New -York; Dr.
Amela Sadagic),
University of Pennsylvania (Philadelphia; Dr. Jane
Mulligan) and
University of North Carolina (Chapel Hill; Jaron Lanier).

Two participating sites had the role of
acquisition sites (AN&S & University of
Pennsylvania) for 3D scene acquisition.

The third one (UNC) was a reconstruction site
for reconstruction and display of remote,
captured scenes.

Tele-Immersion has an environment called
TIDE(Tele-Immersive Data exploration
Environment)
 The goal of TIDE is to employ Tele-Immersion
techniques to create a persistent environment in
which collaborators around the world can engage
in long-term exploration and analysis of massive
scientific data-sets.
 When participants are tele-immersed, , they are
able to see and interact with each other and
objects in a shared virtual environment. Their
presence will be depicted by life-like
representations of themselves (avatars)

 The
environment will persist even when all
the participants have left it.
 Participants
may even leave messages for
their colleagues who can then replay them as
a full audio, video and gestural stream.
 All
users are separated by hundreds of miles
but appear collocated able to see each other
as either a video image or as a simplified
virtual representation (commonly known as
an avatar).
 Avatars are generated by real-time, image
capture, and modeling techniques.
 Each avatar has arms and hands so that they
may convey natural gesture such as pointing
at areas of interest in the visualization.
