  1. Learn what it is Learn what it can do Learn how it can be used in education Augmented Reality Presented by Group 1 Kelly Nightengale Patti Rose

  2. What Is Augmented Reality? • The overlay of computer-presented information on top of the real world • Combines real and virtual realities • Interactive in real time • Registered in 3D • Not the same as “virtual reality”

  3. Augmented vs. Virtual Realities • Virtual reality • Immerses the viewer into computer-generated environments • Requires equipment which completely obstructs visual view of physical objects in the real world • Augmented reality • Augments or adds graphics, audio, and other sensory enhancements to the natural world as it exists

  4. Reality Continuum • Virtual and real environments are at opposite ends of this continuum • AR is closer to the real environment

  5. Historical Background • 1957-62 – Morton Heilig, Sensorama • 1966 – Ivan Sutherland, head-mounted display • 1975 – Myron Krueger, Videoplace • 1989 – Jaron Lanier coined the term Virtual Reality • 1992 – Tom Caudell coined the term Augmented Reality

  6. Historical Timeline • 1994 – Julie Martin, AR Theater • 1999 – Hirokazu Kato, AR Toolkit • 2000 – Bruce Thomas, ARQuake • 2008-09 – Wikitude, AR Travel Guide and Navigation System • 2009 – AR Toolkit ported to Adobe Flash

  7. How Does AR Work? • Requires Internet connection • Can be accomplished in two ways by: • Looking at a screen showing visible and augmented objects • Looking through a device using the generated screen display

  8. Example s: Looking at a Screen • Yellow “first down” line • Direction of ice hockey puck • Giant logos or ads on athletic fields • World record lines for swimming events

  9. Examples: Looking Through Device • Creative photography • Navigation systems

  10. Technology • Drivers: video games, cell phone apps • Display types: • Head-mounted, or heads-up, displays • Handheld displays • Spatial displays

  11. Head-Mounted / Heads-Up Displays • Combines and displays physical world images and virtual graphical objects SVGA Head-Mounted Display Vehicle Heads-Up Display

  12. Handheld Displays • Small handheld computing device • Uses global positioning systems (GPS) iPhone Applications

  13. Spatial Displays • Nothing to wear and/or carry • Uses digital projectors to display information • Marker-based and markerless devices AR Phone Keypad AR Keyboard

  14. Why AR Applications? • Wireless mobile devices • Anywhere, anytime access • State-of-the-art cell phones • Available applications

  15. Advertising Applications • Promote products via interactive AR applications Movie character speaks to you when you pass her outdoor movie poster City Sites Tour

  16. Marketing Applications • Assist consumers on location with ratings, reviews, and other information Restaurant search Social shopper

  17. Industrial Applications • Compare the data of digital mock-ups with physical mock-ups • Provide instructions, specs, and training for mechanics and machine operators

  18. Scientific Applications • Visualize 3D phenomena • Display interactive analysis of terrain characteristics Terrain rendering Whole body PET scan

  19. Arts Applications • Create art over real art • Simulate construction projects • Create virtual objects on locations

  20. Arts Applications • Launch interactive AR music videos • Visit historical sites and step back in time

  21. Arts Applications • Project AR into musical stage shows • Duran Duran Animated character at concert

  22. Educational Applications • Provide powerful contextual, explorative, and discovery learning experiences • Show network learning • Facilitate collaboration among distributed team members • Create 3D graphics of curriculum content • Overlay factual onto view of real world

  23. Educational Applications • Teach critical thinking, science, and social studies through AR gaming Military Strategy Game Racetrack Pit Strategy Game

  24. Educational Applications • Generate models in different settings • Have books come alive

  25. Other Educational Applications • Astronomy • Google’s SkyMap • pUniverse • Architecture • ARSights • Computer Science • Student Guides

  26. AR Video Clips • http://www.youtube.com/watch?v=ZKw_Mp5YkaE • http://www.youtube.com/watch?v=1El-kW1rebs&feature=watch_response • http://www.youtube.com/watch?v=5M-oAmBDcZk&feature=related

  27. Pending / Future Applications • Expanding a PC screen into the real world • “Holodecks” • Replacement of cell phone and vehicle navigation screens • Virtual everything • Virtual gadgetry • Subscriptions to group-specific AR feeds • Virtual retinal displays • AR-enabled contact lenses

  28. NLE Benefits of AR • Exposure to learning experiences • Connected to many learning opportunities • Learn from anywhere and share with anyone • Used to enhance collaborative tasks • Support of seamless interaction between real and virtual environments • Use of a tangible interface metaphor for object manipulation • Ability to transition smoothly between reality and virtuality

  29. Instructional Strategies of AR • Learning goes beyond space and time to extend past the current semester • Community-Community Interaction • Learners get real time, up-to-date information • Aggregation • Learners combine online content with online resources to enhance learning • Mash Up

  30. Instructional Strategies of AR • Learners apply visualizations (2D and 3D) to enhance learning • Info-Viz • Learners use mobile devices to gain knowledge • Mobile learning • Learners use distant network servers for web applications • Cloud computing

  31. Drawbacks of AR • Accuracy • Large margin of error • Standards • No open standards among AR browsers • Availability of AR-capable devices • SmartPhones only
