  • 1. Augmented Reality
    What is it, and how does it fit into higher education?
    April 2010 Tech Talk
    Rebecca Miller
  • 2. AR: What is it?
    “Augmented reality” (AR) refers to a display in which simulated imagery, graphics, or other information is superimposed on a view of the surrounding environment
    Describes the enrichment of the real world with the virtual
    A common example? The yellow “first down” line often see during TV broadcasts of football games
  • 3. AR Explained

  • 4. Why now?
    Both the Horizon Report and the ALA TechTrends Midwinter Webinar mention AR as one of the top technologies applicable to libraries and higher education
    Advances in smart phones, laptops, and other mobile devices have allowed for AR to enter the mainstream
  • 5. Augmented Reality Conference!
  • 6. Before mainstream…
    The expression “augmented reality” was coinced in 1990 by a Boeing researcher
    AR, though, existed before the term did
    Applications of this technology appeared in the late 1950s:
    The “Sensorama,” from U.S. Patent #3050870
    Developed by Morton Heilig in 1955, who saw theater as a an experience to encompass all senses
  • 7. More “before”
    • In the 1960s, Ivan Sutherland invents the head-mounted display (HMD), which offered an early version of AR:
    • 8. While some of these
    only offer a computer-generated image, some HMDs superimpose images on a real-world view
    • This is often seen in gaming
  • HMDs
    Interestingly, the HMD is even used in sports; systems were developed for a Formula One racecar driver and BMW.
    The HMD in these cases will display race crew data and still allow the driver to see the road.
  • 9. Back to the timeline
    In 1992, the first major paper on AR (a system prototype) is presented, and then published in Communications of the ACM in 1993
    ARToolKit developed in 1999
    Software library for building AR applications

    ARQuake developed in 2000
    AR version of the Quake video game
    Never became commercial, but is credited with generating a lot of interest in AR
  • 10. The Mobile world
    The iPhone Yelp app “Monocle” uses the iPhone’s camera and little tags that indicate names, distances, and user ratings of nearby restaurants, bars, and other venues. (August 2009)
    Similarly, the Wikitude AR Travel guide is launched for Android:

  • 13. Applications for Libraries
    During the ALA TechTrends Midwinter 2010 Webinar, AR applications were suggested:
    Exhibits
    Immersive Games
    Architecture (architectural planning)
    Community Guides
    Retrieving books, book reviews, author information while in stacks
