Augmented Reality (AR) is a variation of VR. VR technologies completely immerse a user inside a

synthetic environment. While immersed, the user cannot see the real world around him.

In contrast, AR allows the user to see the real world, with virtual objects superimposed upon the real world.

AR supplements reality, rather than completely replacing it. It creates the illusion that the virtual and real objects coexisted in the same space.

AR can be taken as the "middle ground“ between VR (completely synthetic) and telepresence (completely real)

AUGMENTED REALITY

A combination of a real world and the virtual world

An Augmented Reality system generates a composite view for the user. It’s a combination of the real scene viewed by the user and a virtual scene generated by the computer that augmented the scene with additional information.

Augmented Reality vs. Virtual Reality

Augmented Reality: Computing device

augments the real world scene

User maintains a sense of presence in real world

Virtual Reality: Totally immersive

environment Visual senses are

under control of system.

Typically, the real-world visual scene in an AR display is captured by video or directly viewed.

Most current AR displays are designed using see-through HMDs which allow the observer to view the real world directly with the naked eye.

Augmented RealityTechniques

• Heads Mounted Display• Handheld Devices• Spatial Devices

Head Mounted DisplayUser can simultaneously view both the real

world and the virtual world.Most challenging technique among all AR techniques.Works very good in limited environment.

Handheld Devices

15

• Most commonly used AR Devices• Works on Smartphones• Uses a variety of Sensors• Most Applications are Android based

Handheld Devices

16

Spatial Devices

• Multiple Users can interact with the system.

• User does not carry any device with him.

• The data is projected onto real world entities.

• Can support large areas of displays
