Augmented Reality An Evolution in Human-Computer Interaction

Augmented Reality
A term coined by Boeing researcher, Tom Caudel, which has since come to mean “digital information overlaid on
the physical world”
- (Holden, 2009)
Augmented Reality How it Works
Sensing
• Camera
• Geo-location
• Orientation Sensor
• Digital Compass
Augmenting
• Identifying
• Contextualizing
• Rendering
Presenting
• HUDs
• See-through displays
• Mobile-displays
AR Applications
Properties
combines real and virtual objects in a real environment;
runs interactively, and in real time; and
registers (aligns) real and virtual objects with each other.
- (Azuma, Baillot, MacIntyre, Behringer, & Feiner, 2001)
AR Applications
Google Goggles: mobile application that allows users to search for information about an object in the real-world by simply taking a picture of it.
Layar World Browser: A “Real-World Browser” that allows users to scan their environment and visualize information on objects surrounding them.
Wikitude World Browser: A “Real-World Browser” that allows users to scan their environment and visualize information on objects surrounding them (similar to the Layar Browser)
Microsoft Kinect: Microsoft’s gesture recognition peripheral for the Xbox 360 gaming console
PlayStation Eye: gesture-recognition peripheral that allows users to control and play video games by actual physical actions (gestures)
AR in Education and Corporations
Extended reach of AR has now allowed us to bring education and training into a wider domain by introducing digital information into the real world.
Books
Immersive role-playing games
Training and Learning content
Military simulations
Managing Complex AR Systems (4-Tier Model)
As AR systems and applications expand in scale and scope (ubiquitous AR), so do the complexities of managing interactions and
information they provide.
Managing Complex AR Systems (4-Tier Model)
4 Tier Structure for Managing complex AR models (Schmalstieg, et al., 2007)
Managing Complex AR Systems (4-Tier Model)
4Tier Model provides:
Structure
Reusability
Composability
Flexibllity
To allow for:
Scalability
Interoperability
