Applications of Augmented Reality in Education

Educational Applications of AR 0 Play Video 1 (ARMix.WMV)

Definition by Ron Azuma 0 To avoid limiting AR to a specific technology, AR system should have the following characteristics: 0 Combines real and virtual elements 0 Interactive in real time 0 Registered in 3D

Definition 0 Augmented 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. ~Wikipedia

Milgram’s Reality-Virtuality Continuum

History Ivan Sutherland invents HMD – Tom Caudell coins the phrase Augmented Reality – First functioning AR systems appear (military) Hirokazu Kato creates ARToolKit at HITLab – ARToolKit ported to Flash by Saqoosha

Workflow Create 3D models Export to.3DS,.DAE or.OBJ Create fiduciary marker Print fiduciary marker Connect the camera Load all into AR software Run AR software

3D Models 0 Google 3D Warehouse good source of 3D models 0 Searching for 3D models will save you a lot of time

Working with 2D models 0 2D images (JPEG, GIF), Video Clips (MPEG, MOV)

Fiduciary Marker Create markers Print Markers

Recording with FRAPS 0 To preserve AR lessons, one can record the screen output with FRAPS 0 Captured video can be produced into video lectures and offered to learners via YouTube, Vimeo etc…

Research Projects 0 In-class live AR Experiments 0 Spanish 101 (Classroom, Coffee Shop and Simpsons) 0 Creating AR instructional materials (online and in- class) 0 Warehouse security survey 0 Mechanism and progression of a building collapse 0 Enclosure fire dynamics 0 AR Solar system

Theoretical Framework 0 Cognitive Load Theory 0 Constructivism 0 Social Learning Theory 0 Instructional Design 0 Multiple sensory inputs (tactile, audio and visual) 0 Spatial abilities and intelligence

Findings 0 Student attitudes towards learning with AR 0 Student performance 0 Instructors feedback 0 AR Design issues 0 Research design issues

AR Limitations 0 AR is simulation of the real concepts/objects 0 Incompatible 3D authoring environments (Blender-Sketchup) 0 Requires medium-higher levels of technical expertise 0 Costs increase with quality/reality of AR
