2. OUTLINE:What is Augmented reality? Augmented reality systemAugmenting our world Example Wikitude , Barcode ScannerImplementation Components of AR (Augmented Reality) system Headmounted display Tracking & orientation Digital compass Mobile computing Applications Limitations Conclusion 3. What is Augmented Reality? Augmented Reality is a field ofcomputer research which deals with combination of reality with computer generated data.It is still in an early stage ofresearch 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 augmentedreality 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 Browserpresents 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 ScannerWe can scan a barcode from a product. The details related that productwill be displayed on your phone. 8. Implementation:To implement there are four things find users location find users orientation (view) generating information augmenting it to users view. Generate data Find users locationFind users orientation (view)Augment generated data to users view 9. Components: Display Tracking system such as GPS Mobile computing 10. Head-mounted Displays(HMDs) Just as a monitor allow us to seetext 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 ofaugmented 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 themovement of users' eyes and heads. 12. AR System needs to know two things1.Where the user is located2.Where he is looking 13. Digital compass A digital compass consists ofsensors 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 ofwearable computers.A wearable computer is a battery powered computersystem worn on the users body(belt etc). 15. Applications:-Education In an Augmented Reality interface students canbe 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 ismore 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 displayscould also highlight troop movements and give soldiers the ability to move to where the enemy cant see them. 17. Gaming How cool would it be to take video games outside? The game could be projected onto the real world aroundyou.One Australian researcher has created a prototype gamethat 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 betweenwhat's real and what's computer-generated by enhancing what we see, hear, feel and smell.
