  1. 1. Augmented Reality Chris Baker Comp 4640
  2. 2. What is Augmented Reality? <ul><li>Augmented reality ( AR ) is a field of computer research which deals with the combination of real-world and computer-generated data. </li></ul><ul><li>Most of the AR research is currently concerned with the use of video imagery which is digitally processed and augmented by adding computer-generated graphics. </li></ul>
  3. 3. What is AR? (cont.) <ul><li>Ronald Azuma defines an augmented reality system as one that: </li></ul><ul><ul><li>Combines real and virtual world aspects </li></ul></ul><ul><ul><li>Is interactive in real-time </li></ul></ul><ul><ul><li>Is registered in three dimensions </li></ul></ul>
  4. 4. Augmented vs. Virtual Reality <ul><li>One of the identifying marks of a virtual reality system is the head mounted display worn by users. </li></ul><ul><li>These displays block out all the external world and present to the wearer a view that is under the complete control of the computer. </li></ul><ul><li>In Augmented Reality, the user must still be aware that he or she is present in the “real world.” </li></ul>
  5. 5. How does AR Work? <ul><li>The basic idea of augmented reality is to superimpose graphics, audio and other sense enhancements over a real-world environment in real-time. </li></ul><ul><li>The graphics will then change to accommodate the user’s eye or head movements. </li></ul>Simulated augmented reality medical image
  6. 6. What is needed? <ul><li>There are three components needed in order to make an augmented-reality system work: </li></ul><ul><ul><li>Head-mounted display </li></ul></ul><ul><ul><li>Tracking system </li></ul></ul><ul><ul><li>Mobile computing power </li></ul></ul>
  7. 7. Current Uses of AR <ul><li>Yellow first down line used on TV broadcasts of football games: </li></ul><ul><ul><li>Real world elements: football field and players </li></ul></ul><ul><ul><li>Virtual element: the yellow line drawn over the image by computers in real-time </li></ul></ul>
  8. 8. Current Uses of AR <ul><li>HUD (Head Up Display): </li></ul><ul><ul><li>Used in commercial aircraft, automobiles, and other applications </li></ul></ul><ul><ul><li>Presents data without requiring the user to look away from his or her usual viewpoint </li></ul></ul>
  9. 9. LifeClipper <ul><li>LifeClipper is a wearable AR system being used in Switzerland. </li></ul><ul><li>When walking around a chosen culturally interesting area, the user will feel as though they are watching a film. </li></ul>
  10. 10. Wikitude – AR Travel Guide <ul><li>Mobile travel guide for the Android platform (open source OS for cell phones). </li></ul><ul><li>Plan a trip or find about current surroundings in real-time. </li></ul>
  11. 11. Future of AR <ul><li>Military : </li></ul><ul><ul><li>The Office of Naval Research has sponsored AR research </li></ul></ul><ul><ul><li>AR system could provide troops with vital information about their surroundings. </li></ul></ul><ul><li>Medical : </li></ul><ul><ul><li>Superimpose an image from an MRI onto a patient’s body. </li></ul></ul><ul><ul><li>This might allow surgeons to pinpoint a tumor to remove. </li></ul></ul><ul><li>Education : </li></ul><ul><ul><li>Used in labs where students can learn more about the experiments they are participating in. </li></ul></ul>
  12. 12. Future of AR <ul><li>Gaming : </li></ul><ul><ul><li>ARQuake is an AR version of the popular game Quake. </li></ul></ul><ul><ul><ul><li>1 st person shooter that allows the user to run around in the real world while playing a game in the computer generated world. </li></ul></ul></ul><ul><ul><ul><li>Uses GPS, a hybrid magnetic and interial orientation sensor, gun controller, and a standard laptop carried in a backpack. </li></ul></ul></ul>
  13. 13. Why continue research in AR? <ul><li>AR systems will instantly recognize what someone is looking at, and retrieve and display the data related to that view. </li></ul><ul><li>There are hundreds of potential applications for such a technology, gaming and entertainment being the most obvious ones. </li></ul><ul><li>Any system that gives people instant information, requiring no research on their part, is bound to be a valuable to anyone in any field. </li></ul>
