Augmenting World History

  1. 1. Augmenting World History { Mobile AR & 9th Grade World History Curriculum Investigators: Nettrice Gaskins & Laurie Marion
  2. 2. What is mobileAugmented Reality (AR)?
  3. 3. Augmented Reality superimposes { virtual or digital content over a live view of the world.Science is no longerfiction.
  4. 4. Platform - A platform is a crucial element in mobile ARdevelopment. A platform might be simply defined as a place tolaunch application/software. The platform provider offers thesoftware developer a coding environment in which to create themobile AR application.Software Development Kit (SDK) - This is typically a set of toolsthat allow for the creation of mobile AR applications (ex. pattern orframe-based AR).Applications – Applications are designed to help users performspecific tasks (user experience, or interaction).Other Key Terms ToKnow
  5. 5. Mobile AR Development
  6. 6. Surface AR uses screens, floors, walls, etc. thatrespond to the users touch to give them virtualinformation.Pattern AR uses pattern recognition on ashape, marker, or face and replaces it with a static ormoving virtual element, i.e. a 3Dmodel, audio, video, etc.Outline AR uses the hand, eye, or body outline thatis picked up and merged with virtual elements.Location AR uses GPS coordinates to locate aperson, object, or building and overlay virtualinformation about it as you move through realspace.Hologram AR projects virtual overlays on physicalspace using cameras or projectors to track gesturesor audio signals.Types of AR
  7. 7. { A cylindrical panorama from multiple images taken in Second Life, stitched together using AutoStitch.Virtual Panoramas
  8. 8. { A virtual timeline overlays content from the past on the present, in this case using Historypin.Virtual Timelines
  9. 9. { Using a camera-enabled device an entire scene can reveal stories to users through AR placemarks.Virtual Stories
  10. 10. What is an AR userexperience?
  11. 11. KML (Keyhole Markup Language) + HTML and JavaScript are used to create achannel for media content in the Argon Augmented Reality browser. Subscribingto an Argon channel enables the user to view augmented reality displays on amobile device.
  12. 12. The Qualcomm SDK contains frame markers that can be { embedded in real objects like murals and used by the Argon Augmented Reality Browser (platform).AR User Experience
  13. 13. Students use a camera-enabled mobiledevice, with Argon to view AR content.
  14. 14. Coding Argon for FrameMarkersThe KML file includes Javascript, placement of an image, and identification of themarker.
  15. 15. The name of the channel is on line 48. In Argon, when right arrownext to the channel is clicked, the description is displayed.
  16. 16. The modified KML file (see right)contains specific AR markercontent, including the Javascriptfunction(“updatePlacemarkVisibility”) . Modifying KML to Create an Argon Channel
  17. 17. There are two options for working with frame markers: (1) Print markersonto card stock and cut out centers using an X-acto knife, or (2)Import/open the image(s) and associated Frame Markers using an imagingapplication (e.g. Adobe Photoshop, GIMP); merge (layers) and print. Working with Frame Markers
  18. 18. We can demonstrate how AR Frame Markers work using large posters, images, orreal objects from ancient civilizations. The screen overlays (see inset) and URLs werecreated by the students.
  19. 19. Technology experts provide tutorials, resources, and tools to bring the project(s) together. Teachers and students will provide input on the type of AR, user experience, interface and other design elements for the project(s). Everyone will showcase the project(s) upon completion.Partcipatory DesignProcess
