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
