This document discusses augmented reality (AR), which combines real and virtual scenes. AR was developed in 1968 and allows users to view real scenes augmented with additional computer-generated information. An AR system works by adding virtual objects to real world scenes. Various display technologies are used for AR, including head-mounted displays, glasses, handheld devices, and spatial projections. AR has applications in entertainment, defense, medicine, and education. Examples of AR include virtual dressing rooms and makeup mirrors. AR enhances the real world while virtual reality replaces it entirely.

3. WHAT IS AUGMENTED REALITY?
Combination of real scene
viewed by user and virtual
scene generated by
computer that augments the
scene with additional
information.
Developed by Ivan
Sutherland in 1968.

5. AUGMENTED REALITY SYSTEM

6. HOW IT WORKS
Pick a real world scene.
Add your virtual objects in it.
Delete the real world objects.
Not a Virtual reality as
Environment is real.

7. DISPLAY TECHNOLOGIES
Head Mounted Display:
Device paired to headset such as
harness or helmet.
Eye Glasses:
Eye wear employs camera to
intercept the real world objects and
redisplay its augmented view through
the eye pieces

8. DISPLAY TECHNOLOGIES
Hand Held:
A small device that fits in users hand.
Spatial:
Makes use of digital projectors to display
graphical information.

9. DISPLAY TECHNOLOGIES under development
Contact lenses:
Contains the elements for display embedded
into the lens including integrated circuitry, LEDs
and an antenna for wireless communication.
Virtual Retina Display:
A personal display device.
A display is scanned directly into the viewers
eye.

16. AUGMENTED REALITY VIRTUAL REALITY
Enhances real world. Replaces the real world.
User can interact with the real world. User enters entirely immersive world.
Does not cut off real world. Completely cut off real world.
Merging of digital and physical objects. Computer transmit the sensory data to user
Only part of sensorial experience is digital. All of your sensorial experience is digital.
User maintains the sense of being in real world Senses are under control of Computer system
