TELE-PRESENCE
BY
BHABANI SANKAR SENAPATI
INTRODUCTION


Tele-Presence is a new medium that
enables a user to share a virtual space with
remote participants.
Tele-Presence is the intersection of virtual
reality and video-conferencing.
DEFINITIONS…

Capture of sensory data in 3 spatial
dimensions in real time from multiple
physically separated spaces,the projection
of data into shared virtual environments
and the projection of the virtual
environment into immersive physical
environment, constitute the emerging
technology of Tele-Presence.

Tele-presence is obtained by merging
Virtual Reality by Collaboration Technology.
ENGINEERING INVOLVED



Recognizing human presence
Tracking human environment interaction
Projecting this in a realistic 3D form on a
stereo immersive surface.
RECOGNITION



Sea of seven cameras
5 separate views are interspersed by a
computer algorithm to produce a single
seamless 3D image.
2 additional cameras are employed that
capture lighting,viewer perspective and
depth.
TRACKING



Hi Ball tracker is strapped to the viewer’s
head.
‘Virtual touch’ is the Haptics (touchsimulation) technology that makes it
possible to reach out and touch someone.
Haptic gloves,a network of exoskeleton
tendons is worn by the user.
PROJECTION


8 Computer controlled front projectors,a
stereo-immersive surface or screen
coupled with polarized lens or glasses worn
by the user
16 microphones with Projection speakers
which give the sound direction.

APPLICATIONS




Connecting Communities
Remote Surgery
Education
Sign language communication
CONCLUSION

With the eventual nationwide
implementation of Internet Tele-Presence
will become a public reality and reveal a
whole new vista of communication
projects.
