What is Augmented Reality (AR) ?

• AR is when digital data is “layered on top” of a real place or controlled by a real life environment

Our DefinitionAugmenting the real-world with data

Augmented Reality V.S. Virtual Reality

Augmented 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

Virtual Reality• Senses are under control of system• Need a mechanism to feed virtual world to

user

Milgram’s Reality-Virtuality continuum

Is this Augmented Reality?

Yes No

Is this Augmented Reality?

Building Augmented reality

Supporting AR Design• Hardware

– Use of advanced displays .

– Sensors to detect real environment actions .

Display Technologies

• Monitor Based

– Laptops

– Cell phones

– Projectors .

Display Technologies

• Head Mounted Displays:

– Video see-through

– Optical see-through

Supporting AR Design

• Software Requirements

– Computer Vision systems

– 3D rendering systems

– All in REAL‐TIME

Examples of AR

• Augmented Reality in class room

• Augmented Reality in library

• Augmented Reality in training

Classroom• Physical education-demonstration and

investigation of major muscle group

library• Change 2D to 3D reading

• Language interactive reading

library

Training

• BMW glasses

Already using augmented reality!!

3D glasses

Google glasses

Augmented reality in future

Summary• Advantage of Augmented Reality

• Brilliant Technology

• Infinite apps
