  2. What is Augmented Reality? • Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data. • 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.

  3. What is AR? (cont.) • Ronald Azuma defines an augmented reality system as one that: • Combines real and virtual world aspects • Is interactive in real-time • Is registered in three dimensions

  4. Augmented vs. Virtual Reality • One of the identifying marks of a virtual reality system is the head mounted display worn by users. • These displays block out all the external world and present to the wearer a view that is under the complete control of the computer. • In Augmented Reality, the user must still be aware that he or she is present in the “real world.”

  5. How does AR Work? • The basic idea of augmented reality is to superimpose graphics, audio and other sense enhancements over a real-world environment in real-time. • The graphics will then change to accommodate the user’s eye or head movements. Simulated augmented reality medical image

  6. What is needed? • There are three components needed in order to make an augmented-reality system work: • Head-mounted display • Tracking system • Mobile computing power

  7. Current Uses of AR • Yellow first down line used on TV broadcasts of football games: • Real world elements: football field and players • Virtual element: the yellow line drawn over the image by computers in real-time

  8. Current Uses of AR • HUD (Head Up Display): • Used in commercial aircraft, automobiles, and other applications • Presents data without requiring the user to look away from his or her usual viewpoint

  9. LifeClipper • LifeClipper is a wearable AR system being used in Switzerland. • When walking around a chosen culturally interesting area, the user will feel as though they are watching a film.

  10. Wikitude – AR Travel Guide • Mobile travel guide for the Android platform (open source OS for cell phones). • Plan a trip or find about current surroundings in real-time.

  11. Future of AR • Military: • The Office of Naval Research has sponsored AR research • AR system could provide troops with vital information about their surroundings. • Medical: • Superimpose an image from an MRI onto a patient’s body. • This might allow surgeons to pinpoint a tumor to remove. • Education: • Used in labs where students can learn more about the experiments they are participating in.

  12. Future of AR • Gaming: • ARQuake is an AR version of the popular game Quake. • 1st person shooter that allows the user to run around in the real world while playing a game in the computer generated world. • Uses GPS, a hybrid magnetic and interial orientation sensor, gun controller, and a standard laptop carried in a backpack.

  13. Why continue research in AR? • AR systems will instantly recognize what someone is looking at, and retrieve and display the data related to that view. • There are hundreds of potential applications for such a technology, gaming and entertainment being the most obvious ones. • Any system that gives people instant information, requiring no research on their part, is bound to be a valuable to anyone in any field.
