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 3 D
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 0 1966 - Ivan Sutherland invents HMD 0 1990 – Tom Caudell coins the phrase Augmented Reality 0 1992 – First functioning AR systems appear (military) 0 1999 - Hirokazu Kato creates ARTool. Kit at HITLab 0 2009 – ARTool. Kit ported to Flash by Saqoosha
Famous Applications of AR 0 GE – Plug into the smart grid 0 Ironman 0 BMW 0 Adidas 0 LEGO
AR Interfaces/Displays 0 Head Mounted Displays (HMD) 0 Hand-Held Displays 0 Spatial Displays (environmentally integrated) 0 Monitors 0 Projectors Costs HMD Mobile Monitor

AR Software 0 Build. AR – Commercial license 0 ARToolkit – Open source libraries (build your own) 0 FLARTool. Kit (Flash implementation of ARTool. Kit) 0 SLARTool. Kit (Silverlight implementation of ARTool. Kit)
3 D Tools 0 Google Sketch. Up (free/commercial) 0 Blender (Free) 0 Art of Illusion (free) 0 Autodesk 3 D Studio Max, Maya (free/commercial)
Workflow Create 3 D models Export to. 3 DS, . DAE or. OBJ Create fiduciary marker Print fiduciary marker Connect the camera Load all into AR software Run AR software
3 D Models 0 Google 3 D Warehouse good source of 3 D models 0 Searching for 3 D models will save you a lot of time
Working with 2 D models 0 2 D 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 You. Tube, 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 inclass) 0 0 Warehouse security survey Mechanism and progression of a building collapse Enclosure fire dynamics 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 0 AR is simulation of the real concepts/objects Incompatible 3 D authoring environments (Blender-Sketchup) Requires medium-higher levels of technical expertise Costs increase with quality/reality of AR
