Transcript

  • 1. Name- Utkarsh Tyagi Semester 5th B.Tech (EC) GEHU
  • 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. 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. 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. 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. 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. 2.Barcode Scanner We can scan a barcode from a product. The details related that product will be displayed on your phone.
  • 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. Components:• Display • Tracking system such as GPS • Mobile computing
  • 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. 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. AR System needs to know two things 1.Where the user is located 2.Where he is looking
  • 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. 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. 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. 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. 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. Limitations:Accurate tracking and orientation
  • 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.
