1. Augmented Reality
And Virtual Reality

2. What Is Augmented Reality (AR)?
A combination of
a real scene viewed by a user and
a virtual scene generated by a computer that augments the scene with additional information.

3. Nuts and Bolts of AR Characteristics of AR Hardware Needed
It combines real and virtual
It is interactive in real time
It is registered in 3D
Hardware Needed
Display
Input devices-camera
Processer-CPU
Sensors-accelerometer
Tracking-GPS, compass

4. What is Virtual Reality (VR)?
Virtual reality or virtual realities (VR), also known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence that environment in a way that allows the user to interact with it.

5. A true VR experience should include:
Nuts and Bolts of VR
A true VR experience should include:
Three-dimensional images that appear to be life-sized from the perspective of the user
The ability to track a user's motions, particula­rly his head and eye movements, and correspondingly adjust the images on the user's display to reflect the change in perspective

6. Nuts and Bolts of VR Hardware Needed
A device-phone either android or iOs
Google cardboard, or another VR headset
Google cardboard app

7. Augmented Reality vs. Virtual Reality
System augments the real world scene
User maintains a sense of presence in real world
Needs a mechanism to combine virtual and real worlds
Hard to register real and virtual
Virtual Reality
Totally immersive environment
Senses are under control of system
Need a mechanism to feed virtual world to user
Hard to make VR world interesting
Computer generated virtual objects must be accurately registers with the real
in all dimensions.
Errors in registration prevent the real and virtual images from being seen as fused.
Registration must be maintained while the user moves around in the virtual
environment.
Changes in registration can be distracting or physically disturbing.
