Definition by Ron Azuma
0To avoid limiting AR to a specific technology, AR system should have the following characteristics:0Combines real and virtual elements0Interactive in real time0Registered in 3D
Definition
0Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics.

History
01966 - Ivan Sutherland invents HMD 01990 – Tom Caudell coins the phrase Augmented
Reality01992 – First functioning AR systems appear (military)01999 - Hirokazu Kato creates ARToolKit at HITLab02009 – ARToolKit ported to Flash by Saqoosha

Workflow
3D Models
0Google 3D Warehouse good source of 3D models
0Searching for 3D models will save you a lot of time
Working with 2D models
02D images (JPEG, GIF), Video Clips (MPEG, MOV)
Fiduciary Marker
• Create markers• Print Markers
Recording with FRAPS
0To preserve AR lessons, one can record the screen output with FRAPS
0Captured video can be produced into video lectures and offered to learners via YouTube, Vimeo etc…
Research Projects
0 In-class live AR Experiments0 Spanish 101 (Classroom, Coffee Shop and Simpsons)
0Creating AR instructional materials (online and in-class)0 Warehouse security survey0 Mechanism and progression of a building collapse0 Enclosure fire dynamics0 AR Solar system
Theoretical Framework
0Cognitive Load Theory0Constructivism0Social Learning Theory0 Instructional Design0Multiple sensory inputs (tactile, audio and visual)0Spatial abilities and intelligence
Findings
0Student attitudes towards learning with AR0Student performance0 Instructors feedback0AR Design issues 0Research design issues
AR Limitations
0 AR is simulation of the real concepts/objects0 Incompatible 3D authoring environments (Blender-Sketchup)0 Requires medium-higher levels of technical expertise0 Costs increase with quality/reality of AR
