Augmented reality

  1. 1. Seminar On Latest Technology Presented By: Aarti Hariramani 09ECACS001
  2. 2. What is it? • Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are merged with (or augmented by) virtual computer- generated imagery - creating a mixed reality.
  3. 3. Virtual reality
  4. 4. Augmented Reality (AR) is a variation of VE/VR. • VR technologies completely immerse a user inside a synthetic environment. While immersed, the user cannot see the real world around him. • In contrast, AR allows the user to see the real world, with virtual objects superimposed upon or composited with the real world. AR supplements reality, rather than completely replacing it. It creates the illusion that the virtual and real objects coexisted in the same space. AR can be thought of as the "middle ground“ between VE (completely synthetic) and telepresence (completely real)
  5. 5. Motivation
  6. 6. • AR enhances a user’s perception of interaction with the real world. • The virtual objects display information that the user cannot directly detect with his own senses. • The information conveyed by the virtual objects helps a user perform real-world tasks. • AR is a specific example of what is known as Intelligence Amplification (IA): using the computer as a tool to make a task easier for a human to perform.
  7. 7. Devices Display
  8. 8. • There are essentially 3 different kinds of displays of augmented reality: • The head mounted display (HMD) is worn on the head or attached to a helmet. This display can resemble goggles or glasses. In some instances, there is a screen that covers a single eye. • The handheld device is a portable computer or mobile smartphone such as the iPhone. • Spatial display makes use of projected graphical displays onto fixed surfaces.

  13. 13. The military, particularly the Office of Naval Research and Defense Advanced Research Projects Agency or DARPA, are some of the original pioneers of augmented reality systems. One of the main uses of augmented reality systems to the military is providing field soldiers crucial information about their surroundings as well as friendly troops and enemy movements in their particular area.

  14. 14. Medical One of the interesting uses for AR in the medical field involves live interactive imaging for assisting physicians, medical students and children. Minimally invasive surgery (MIS) includes procedures where a camera is inserted into the patient's body to help the doctor visualize the procedures he or she is conducting
  15. 15. This form of surgery is aided with the use of AR imagery of a brain superimposed onto the patient's head, giving the doctor a more tangible visualization. Surgery
  16. 16. Augmented Reality applications that can enhance textbooks to have the power to engage a reader in ways that have never been possible. Children learn better the lesson if they see it like a game. In mathematics and geometry the main advantage of using an AR system is that students actually see three dimensional objects. Education
  17. 17. AR in medicine, where an “error” could drive to a disaster. A surgeon learns laparoscopic surgery in an augmented reality situation, there are no real consequences if mistakes are made during training. These types of training provide opportunities for more authentic learning and appeal to multiple learning styles.
  18. 18. Available Mobile Apps
  19. 19. STAR WALK Tells you exactly what stars, constellations, and satellites you’re looking at as you point your device at the sky. The camera records both your position in relation to the sky and where you’re pointing. It then presents information to you about the cosmos. The app also has a feature called Time Machine that shows you what the sky looked like in the past or will look like in the future.
  20. 20. Google Sky Map This Android app lets you point your smartphone camera to the sky and identify the stars, constellations, and planets above you. Details and scenery change in real time as you move your handset across the sky.
  21. 21. Piclings An iOS game that uses the to create level layouts for the game. The game recognizes the images taken by the camera, redefines them digitally, and incorporates them into the game world.
  22. 22. Tissot has launched the first augmented reality window display at which allows consumers on the street the chance to virtually "try-on" a 3D watch from Tissot's pioneering T-Touch watch collection.
  23. 23. Conclusion • Though Augmented Reality has both advantages & disadvantages, it is a great way of delivering entertainment media that uses computer generated graphics transposed over a real life scene.
