  3. 3. AUGMENTED REALITY  Augmented Reality is a field of Electronics which deals with combination of reality with the computer generated data.  The basic idea of augmented reality is to superimpose graphics, audio and other sensory enhancements over a real world environment in real time. Augmented-reality displays will overlay computer-generated graphics onto the real world. 3
  4. 4. AUGMENTED REALITY  An augmented reality system generates a composite view for the user. It is a combination of the real scene viewed by the user and a virtual scene generated by the computer that augments the scene with additional information.  Augmented Reality(AR) is a combination of three factors .These are : Real and virtual world. Interaction in the real time. 3D world. 4
  5. 5. HISTORY  1966: Ivan Sutherland invents the head-mounted display and positions it as a window into a virtual world.  1994: Julie Martin creates first ‘Augmented Reality Theater production’.  2013: Google announces an open beta test of its Google Glass augmented reality glasses. The glasses reach the Internet through Bluetooth, which connects to the wireless service on a user’s cellphone. The glasses respond when a user speaks, touches the frame or moves the head. Fig.2. Ivan Sutherland in 1968 5
  6. 6. COMPONENTS USED IN AUGMENTED REALITY Head mounted display. Tracking system. Mobile computing power(High speed portable computers). 6
  7. 7. HEAD-MOUNTED DISPLAY  Head mounted display will enable us to view graphics and text created by Augmented reality systems.  A typical HMD has either one or two small displays with lenses and semi-transparent mirrors embedded in a helmet, eye-glasses (also known as data glasses) or visor. The display units are miniaturized and may include CRT, LED or OLED. Head mounted display 7
  8. 8. TRACKING SYSTEM  It is used in order to track user’s location with respect to the surrounding. For this two tracking system is used : Global Positioning System(GPS). Hi-Ball Tracking System The Hi ball Tracking System uses an optical sensing device and LED-embedded ceiling tiles to track movements over a short range. 8
  9. 9. MOBILE COMPUTING POWER  For augmented reality systems to work mobile computers are a good option.  Mobile computing can be accomplished with help of wearable computers ,which is the battery powered computer system worn on the user’s body. 9
  10. 10. WORKING 10
  11. 11. APPLICATIONS  EDUCATION: Augmented reality applications can complement a standard curriculum. Text, graphics, video and audio can be superimposed into a student’s real time environment. MILITARY: Augmented reality displays could also highlight troop movements, and provide hidden place for them in the nearby surrounding. 11
  12. 12. APPLICATIONS Sports and Entertainment AR has become common in sports telecasting. Sports and entertainment venues are provided with see-through and overlay augmentation through tracked camera. Medical Augmented Reality can provide the surgeon with information, which are otherwise hidden, such as showing the heartbeat rate, the blood pressure, the state of the patient’s organ, etc. as an X-ray with another such as video.

  13. 13. ADVANTAGES • It is UNIQUE • Have vast majority Content . • Interactivity maintains a viral loop . • Personalization 13
  14. 14. DISADVANTAGES • Physical danger • Privacy control • Difficult to IMPLEMENT 14
  15. 15. SCOPE IN THE FUTURE  Enhanced media applications ,like pseudo holographic virtual screens, virtual surround cinema.  Replacement of cell phones: eye dialing, insertion of information directly into environment.  You may learn things about the city you've lived in for years just by pointing your AR-enabled phone at a nearby park or building. 15
  16. 16. CONCLUSION Augmented reality will further blur the line between what's real and what's computer generated by enhancing what we see, hear, feel. It has possibilities beyond our imagination and perception. It will have huge applications in almost every field. 16
