  1. Applications of Augmented Reality in Education

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

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

  4. Definition • 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

  5. Milgram’s Reality-Virtuality Continuum

  6. History • 1966 - Ivan Sutherland invents HMD • 1990 – Tom Caudell coins the phrase Augmented Reality • 1992 – First functioning AR systems appear (military) • 1999 - Hirokazu Kato creates ARToolKit at HITLab • 2009 – ARToolKit ported to Flash by Saqoosha

  7. Famous Applications of AR • GE – Plug into the smart grid • Ironman • BMW • Adidas • LEGO

  8. AR Interfaces/Displays • Head Mounted Displays (HMD) • Hand-Held Displays • Spatial Displays (environmentally integrated) • Monitors • Projectors Costs

  9. AR Displays - HMD

  10. AR Displays - Hand-Held

  11. AR Displays - Spatial

  12. AR System Design • Fiduciary Marker

  13. Spatial Display AR System • Play video 2 (wanjuAR)

  14. Fiduciary Marker

  15. Web Camera

  16. PC

  17. AR Software • BuildAR – Commercial license • ARToolkit – Open source libraries (build your own) • FLARToolKit(Flash implementation of ARToolKit) • SLARToolKit(Silverlight implementation of ARToolKit)

  18. 3D Tools • Google SketchUp (free/commercial) • Blender (Free) • Art of Illusion (free) • Autodesk 3D Studio Max, Maya (free/commercial)

  19. Workflow

  20. 3D Models • Google 3D Warehouse good source of 3D models • Searching for 3D models will save you a lot of time

  21. Working with 2D models • 2D images (JPEG, GIF), Video Clips (MPEG, MOV)

  22. Fiduciary Marker • Create markers • Print Markers

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

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

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

  26. Findings • Student attitudes towards learning with AR • Student performance • Instructors feedback • AR Design issues • Research design issues

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