TELE IMMERSION



AMAN BABBER


WHAT IS TELEIMMERSION


Teleimmersion is a technology to be implemented
with intenet2 that will enable user in different
geographics location to come together in a simulated
environment to interact .


Users will feel like they are actually looking.talking
and meeting with each other face 2 face in the same
room.


This is achieved using computers that recognize the
presence and movements of individuals and
objects,tracking those individuals and images and
reconstructing them onto one stereo
-
immersive
surface
.

REQUIREMENTS OF THE SYSTEM


Large Display flat screen


Camera cluster units


Work Stations


Set of Speakers and microphones


Infrared lighting setup


HOW TELE
-
IMMERSION WORKS



Two partners separated by 1000 miles collaborate
with each other.


There
is a sea of cameras which provide view of
users and their surroundings
.



Mounted Virtual Mirrors provide each user a view
how his surrounding seems to other
.



At each instant camera generated an image which is
sorted into subsets of overlapping
trio.


The
depth map generated from each trio then
combined into a single view point at a given
moment.


SHARED TABLE ENVIRONMENT


Virtual Reality

Point of view rendering


High
-
quality (spatialized or surround) audio


Haptics (touch and force feedback)


Basis for creating shared work spaces


VIRTUAL REALITY


Virtual Reality is a technology which allows a
user to interact with a computer
-
simulated
environment , be it real or imagined one.


Most current virtual reality environments are
primarily visual experiences ,displayed either on
a computer screen or through special or
stereoscopic displays ,but some simulations
include additional sensory information s, such as
sound through speakers or headphones
.

TELE CUBICLES


A telecubicle has a stereo
-
immersive desk surface as
well as at least two stereo
-
immersive walls.



These three display surfaces meet, in the formation of
a desk against a corner. When a telecubicle is linked to
others on the net, the walls appear to be transparent
passages to the other cubicles.

HOW TELE CUBICLE WORKS
