Augmented reality

  1. 1. Name- Utkarsh Tyagi Semester 5th B.Tech (EC) GEHU
  2. 2. OUTLINE:What is Augmented reality? Augmented reality system Augmenting our world Example – Wikitude , Barcode Scanner Implementation Components of AR (Augmented Reality) system  Head mounted display  Tracking & orientation  Digital compass  Mobile computing Applications Limitations Conclusion
  3. 3. What is Augmented Reality? Augmented Reality is a field of computer research which deals with combination of reality with computer generated data. It is still in an early stage of research and development. possibly by the end of this decade.
  4. 4. Augmented Reality System An augmented reality system is one that •Combine real and virtual world. •Is interactive in real time. •Is registered in 3D.
  5. 5. Augmenting Our World The basic idea of augmented reality is to superimpose graphics, audio and other sense enhancements over a real-world environment . These systems display graphics for only one point of view. Nextgeneration augmented-reality systems will display graphics for each viewer's perspective.
  6. 6. Software based on Augmented Reality … 1.Wikitude – wiki attitude WIKITUDE World Browser presents the user with data about their surroundings, nearby landmarks, and other points of interest by overlaying information on the real-time camera view of a smart-phone.
  7. 7. 2.Barcode Scanner We can scan a barcode from a product. The details related that product will be displayed on your phone.
  8. 8. Implementation:To implement there are four things find user’s location find user’s orientation (view) generating information augmenting it to user’s view. Generate data Find user’s location Find user’s orientation (view) Augment generated data to user’s view
  9. 9. Components:• Display • Tracking system such as GPS • Mobile computing
  10. 10. Head-mounted Displays(HMD’s) Just as a monitor allow us to see text and graphics generated by computers. Head-mounted displays (HMDs) will enable us to view graphics and text created by augmentedreality systems.
  11. 11. Tracking and Orientation The biggest challenge facing developers of augmented reality is the need to know where the user is located in reference to his or her surroundings. There's also the additional problem of tracking the movement of users' eyes and heads.
  12. 12. AR System needs to know two things 1.Where the user is located 2.Where he is looking
  13. 13. Digital compass A digital compass consists of sensors to measure the earth's magnetic field, some conditioning of those sensor signals, and a microcontroller to interpret the data
  14. 14. Mobile Computing Power Wearable computers. Mobile computing can be accomplished with help of wearable computers. A wearable computer is a battery powered computer system worn on the user’s body(belt etc).
  15. 15. Applications:- Education In an Augmented Reality interface students can be seated around a table and see each other at the same time as a virtual heart floating in their midst. This results in conversational behavior that is more similar to natural face-to-face collaboration than to screen based collaboration.
  16. 16. Military The military also uses augmented reality for decades. The idea here is that an augmented-reality system could provide troops with vital information about their surroundings, such as showing where entrances are on the opposite end of the building, somewhat like X-ray vision. Augmented reality displays could also highlight troop movements and give soldiers the ability to move to where the enemy can’t see them.
  17. 17. Gaming  How cool would it be to take video games outside? The game could be projected onto the real world around you. One Australian researcher has created a prototype game that combines Quake, a popular video game, with augmented reality. He put a model of a university campus into the game's software. Now, when he uses this system, the game surrounds him as he walks across campus.
  18. 18. Limitations:Accurate tracking and orientation
  19. 19. Conclusion:Augmented reality will further blur the line between what's real and what's computer-generated by enhancing what we see, hear, feel and smell.
