Augmented Reality

  1. 1. - Yesha Kava SYCO-A
  2. 2.  In fundamental terms, the expression augmented reality, often abbreviated to AR, refers to a simple combination of real and virtual (computer-generated) worlds. Given a real subject, captured on video or camera, the technology augments (= adds to) that real-world image with extra layers of digital information. Combining digital information, photographs and 4G video, streets are represented by three-dimensional graphics which even allow the user to enter buildings and see a live video stream.
  3. 3.  A notable example of an augmented reality app is Recognizer, which links face recognition software to social networking profiles. This means that you could simply capture a persons image in your mobiles viewfinder, and potentially have access to their identity, contact details and a range of personal information. Most Augmented Reality research focuses on see- through devices, usually worn on the head that overlay graphics and text on the users view of surroundings.
  4. 4.  Just as monitors allow us to see text and graphics generated by computers, head-mounted displays (HMDs) will enable us to view graphics and text created by augmented-reality systems.
  5. 5.  There are two basic types of HMDS: ◦ optical see-through ◦ video see-through Optical see-through Video see-through displays: displays:
  6. 6.  Handheld Augment Reality employs a small computing device with a display that fits in a users hand. Handheld AR employed sensors such as digital compasses and GPS units for its six degree of freedom tracking sensors.
  7. 7.  Spatial Augmented Reality (SAR) makes use of digital projectors to display graphical information onto physical objects.
  8. 8.  Objects in the real and virtual worlds have to be properly aligned with respect to each other. Some applications demand accurate registration., e.g., virtual surgery where error can be fatal!! Registration errors can also cause motion-sickness.
  9. 9.  Medical Entertainment Military training Engineering design Robot path planning Manufacturing, Maintenance and Repair Consumer Design Portability
  10. 10.  Technological Limitations: ◦ Displays, trackers, and AR systems in general need to become more accurate, lighter, cheaper, and less power consuming. ◦ The display isn’t very bright and completely washes out in bright sunlight. ◦ The equipment isn’t nearly as portable as desired. Since the user must wear the PC, sensors, display, batteries, and everything else required. User Interface Limitations:o Need a better understanding of how to display data to a user and how the user should interact with the data.
  11. 11.  AR has a great future as it promises better navigation and interaction with real and virtual world in ways which has previously been unimaginable.
