TELE IMMERSION

WHAT IS TELEIMMERSIONTeleimmersion 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 SYSTEMLarge Display flat screenCamera cluster unitsWork StationsSet of Speakers and microphonesInfrared 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

– Immersive high-resolution real-time stereo graphics – 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 CUBICLESA 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.
