- Amazing Augmented Reality


2/18

Computer Graphics

Closer to Real Environment

Changes the view to look at World

Superimpose graphics

Augmented ; the Walkman of the 21stCentury

Always fit the perspective

What You See is What you really Get

Introduction

Basic role of Hologram



3/18

Preliminary

Holograms are diffractive structures

Three-Dimensional Display Images

Image Projection Systems

Unique Optical Elements

Hologram

Types of Hologram

Transmission

Rainbow



4/18

It is a Greek Word

Science of producing holograms

Advanced form of photographythat allow to record image in 3D form

Volumetric Display

(particularly used in science fiction)

Holography

Technically different from Photography



5/18

Dynamic Holography

Non Optical Holography

Digital Holography

Types of Holography

Reflection Holography

Rainbow Holography

Electron

Acoustics



6/18

Physical Absence Shows Presence"

New Communication Technology with interaction

Gives simulated environment

HolographicEnvironment

It added Graphics, Sound, Haptics and smell

Super imposition of Graphics

In Star Trek the Starship live out their infantasies room holodeck"

Holographic Room at both End



7/18

A user experiences immersion

the combination of a sense ofImmersion andInteractivityis called Telepresence.

Virtual Reality Immersion

Causes to become unaware of your real surroundings

Two main components of immersion:Depth of information andBreadth of information

OR Cave Automatic Virtual Environment

Haptic System ; gives user force feedback andtouch interaction

The feeling of being inside and a part of that world.



8/18

Cave automatic virtual environment (CAVE)Special 3-D virtual reality room that can display images of peopleand objects in other CAVEsThese are holographic devicesHolographic deviceCreates, captures, and/or displays images in 3-D form

Looks Like This



9/18

Holodeck

Scientific Community says"Tele-immersion"

The Holodeck was a giant,

Holographic Projection Room

That allowed the crew toTouch andInteract with projections



10/18

Tele-immersion

Tele-immersion will allow usto manipulate holographic projectionsas if they were real objects.

It will soon meet in a Tele-immersive environmentand shake hands with

holographic images of their co-workers

We can no longer see the personIn view of that one camera

With tele-immersion

people can walk out of the view of the camera

Will blur the lines betweenreal andcomputer-generated images



11/18

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 imageson a Stereo-Immersive Surface.

Internet 2

Display Technologies (Stereo immersive display)

Haptic sensors



12/18

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 realityIn case remotely

The next step is to mergeTele-immersion and Virtual Realityto allow users to alter the scenes that they see



13/18

Virtual Forces/ Security

Virtual Doors, Walls and Windows

Medical Science

Storage Devices

Brain Mapping

Holography in art

Possible Applications



14/18

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



15/18

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



16/18

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



17/18

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
