Augmented Reality

  1. 1. Augmented Reality<br />What is it, and how does it fit into higher education?<br />April 2010 Tech Talk<br />Rebecca Miller<br />
  2. 2. AR: What is it?<br />“Augmented reality” (AR) refers to a display in which simulated imagery, graphics, or other information is superimposed on a view of the surrounding environment<br />Describes the enrichment of the real world with the virtual<br />A common example? The yellow “first down” line often see during TV broadcasts of football games<br />
  3. 3. AR Explained<br />by Common Craft<br /><br />
  4. 4. Why now?<br />Both the Horizon Report and the ALA TechTrends Midwinter Webinar mention AR as one of the top technologies applicable to libraries and higher education<br />Advances in smart phones, laptops, and other mobile devices have allowed for AR to enter the mainstream<br />
  5. 5. Augmented Reality Conference!<br />
  6. 6. Before mainstream…<br />The expression “augmented reality” was coinced in 1990 by a Boeing researcher<br />AR, though, existed before the term did<br />Applications of this technology appeared in the late 1950s:<br />The “Sensorama,” from U.S. Patent #3050870<br />Developed by Morton Heilig in 1955, who saw theater as a an experience to encompass all senses<br />
  7. 7. More “before”<br /><ul><li>In the 1960s, Ivan Sutherland invents the head-mounted display (HMD), which offered an early version of AR:
  8. 8. While some of these </li></ul> only offer a computer-generated image, some HMDs superimpose images on a real-world view<br /><ul><li>This is often seen in gaming </li></li></ul><li>HMDs<br />Interestingly, the HMD is even used in sports; systems were developed for a Formula One racecar driver and BMW. <br />The HMD in these cases will display race crew data and still allow the driver to see the road. <br />
  9. 9. Back to the timeline<br />In 1992, the first major paper on AR (a system prototype) is presented, and then published in Communications of the ACM in 1993<br />ARToolKit developed in 1999<br />Software library for building AR applications<br /><br />Projects:<br />ARQuake developed in 2000<br />AR version of the Quake video game <br />Never became commercial, but is credited with generating a lot of interest in AR<br />
  10. 10. The Mobile world<br />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)<br />Similarly, the Wikitude AR Travel guide is launched for Android:<br /><br />
  11. 11. More interesting examples<br />November 2009: Esquire’s Augmented Reality issue: <br /><br />Yelp: <br /><br />Social Augmented Reality:<br />Foursquare for Layar:<br />
  12. 12. In higher education<br />Books:<br />University of Wisconsin, ARIS Mobile Media Learning Games:<br />Georgia Tech, Augmented Environments Lab:<br />Wikitude World Browser:<br />iTacitus and Visual Time Machine:<br />
  13. 13. Applications for Libraries<br />During the ALA TechTrends Midwinter 2010 Webinar, AR applications were suggested:<br />Exhibits<br />Immersive Games<br />Architecture (architectural planning)<br />Community Guides<br />Retrieving books, book reviews, author information while in stacks<br /><br />(minutes 27- 34.30)<br />
  14. 14. AR Development<br />ARML:<br /><br />
