  1. TELE-IMMERSION & INTERNET2 PRESENTED BY Geenas GS S7, ECE Roll.No: 7215

  2. Contents • Introduction

  3. 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.

  4. What is tele-immersion ? • Tele-Immersion (TI) is defined as the integration of audio and video conferencing, via image-based modeling, with collaborative virtual reality • New medium that enables a user to share a virtual space with remote participants.

  5. Contd.. • 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 computer-vision technologies.

  6. History • 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

  7. First feel of tele-immersion • 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. AmelaSadagic), • University of Pennsylvania (Philadelphia; Dr. Jane Mulligan) and • University of North Carolina (Chapel Hill; JaronLanier).

  8. Contd.. • 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.

  10. Science of tele immersion • 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)

  11. CONTD • 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.

  12. Contd.. • 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.
