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
• 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 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.
