Holographic Environment
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
- Amazing Augmented Reality
Computer Graphics
Closer to Real Environment
Changes the view to look at World
Superimpose graphics
Augmented ; “the Walkman of the 21st Century”
Always fit the perspective
What You See is What you really Get
Introduction
Basic role of “Hologram”Krishna Kumar Bohra (KKB), MCA LMCST
www.selectall.wordpress.com
Preliminary
Holograms are diffractive structures
Three-Dimensional Display Images
Image Projection Systems
Unique Optical Elements
Hologram
Types of Hologram
Transmission
Rainbow
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
It is a Greek Word
Science of producing holograms
Advanced form of photography that allow to record image in 3D form
Volumetric Display (particularly used in science fiction)
Holography
Technically different from ‘Photography’
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Dynamic Holography
Non Optical Holography
Digital Holography
Types of Holography
Reflection Holography
Rainbow Holography
Electron
Acoustics

“Physical Absence Shows Presence"
New Communication Technology with interaction
Gives simulated environment
Holographic Environment
It added Graphics, Sound, Haptics and smell
Super imposition of Graphics
In Star Trek the Starship live out their in fantasies room “holodeck"
Holographic Room at both End

A user experiences immersion
the combination of a sense of Immersion and Interactivityis called “Telepresence”.
Virtual Reality Immersion
Causes to become unaware of your real surroundings
Two main components of immersion: Depth of information and Breadth of information
OR Cave Automatic Virtual Environment
Haptic System ; gives user force feedback and touch interaction
The feeling of being inside and a part of that world.

Cave automatic virtual environment (CAVE) Special 3-D virtual reality room that can display images of people and objects in other CAVEsThese are holographic devicesHolographic device Creates, captures, and/or displays images in 3-D form
Looks Like This
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Holodeck
Scientific Community says "Tele-immersion"
The Holodeck was a giant,Holographic Projection Room
That allowed the crew to Touch and Interact with projections
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Tele-immersion
Tele-immersion will allow us to manipulate holographic projections as if they were real objects.
It will soon meet in a Tele-immersive environment and shake hands with holographic images of their co-workers
We can no longer see the person In view of that one camera
With tele-immersionpeople can walk out of the view of the camera
Will blur the lines between real and computer-generated images
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Build Up
This Environment is being generated by computers( computing speeds 1000 times faster than normal PC)
Steps to constructing a holographic environment
The computer recognizes the presence & movements of people and objects.
The computer tracks those images.
The computer projects those images on a Stereo-Immersive Surface.
Internet 2
Display Technologies (Stereo – immersive display)
Haptic sensors Krishna Kumar Bohra (KKB), MCA LMCST

Is it Virtual Reality? No
Key Difference No Interaction
Beyond Virtual Reality and Video Conferencing
No Webcam need
No Jerky Video
View of camera
Tele-immersion may sound similar to virtual reality In case remotely
The next step is to merge Tele-immersion and Virtual Reality to allow users to alter the scenes that they see
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Virtual Forces/ Security
Virtual Doors, Walls and Windows
Medical Science
Storage Devices
Brain Mapping
Holography in art
Possible Applications
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
National Tele-Immersion Initiative (NTII)
Group On …
University of North Carolina (UNC),
University of Pennsylvania
Advanced Networks and Services
There are several groups working together in one way
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Limitations
Color Reproduction is not perfect
Holograms generally displayed incontrolled environment for displaypurposes
Brightness, shadows, etc are difficult to adjust
Light scattering from film and support structure
Cost wise ; its very costly
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Most Important Considerations
Technology for betterment of society
It's everywhere
It's inescapable
It's up to us how it gets used
Exchanging privacy for convenience
You do this in small ways
Preliminary Conclusions
Krishna Kumar Bohra (KKB), MCA LMCSTwww.selectall.wordpress.com
Business uses IT to make money
that's Okay !
Technology can also be used when no money is to be made
that's GREAT
Should never expect Medical Science to make money from this technology
Ethics
