  3. 3. What is Virtual Reality (VR) ? • Virtual Reality is a computer generated, multi-sensory information program which tracks a user in real time i.e. computer system is used to create an artificial world in which the user has the impression of being in that world ,with the ability to navigate through and manipulate objects in that world.
  4. 4. Virtual Reality Concepts • The concepts behind virtual reality are based upon theories about : • A long held human desire to escape the boundaries of the ‘real world’ by embracing cyberspace. • Once there we can interact with this virtual environment in a more naturalistic manner which will generate new forms of human-machine interaction (HMI).
  5. 5. Augmented (AR) & Mixed Reality (MR)
  6. 6. Augmented Reality (AR) • Refers to a system in which the user views and acts within an enhanced version of the real world. The enhancements are virtual (computer- generated), and can include objects or information.
  7. 7. Mixed Reality (MR) • sometimes referred to as hybrid reality • encompassing both augmented reality and augmented virtuality • refers to the merging of real and virtual worlds to produce new environments and visualisations where physical and digital objects co-exist and interact in real time
  8. 8. Mixed Reality Continuum Mixed Reality (MR) Reality Augmented Reality (AR) Augmented Virtuality (AV) Virtuality
  9. 9. AR/MR Application Areas… • Maintenance • Training • Tourism/ Cultural Heritage • Design / Construction • Battlefield Information Display
  10. 10. Used in Sports
  11. 11. AR IN GAMES
  12. 12. TYPES OF AR Marker-based AR Markerless AR GPS & Compass Technology
  13. 13. MARKER BASED  Marker-based AR uses a camera and a visual marker to determine the center, orientation, and range of its spherical coordinate system.  Most of the time, the applications using markers are based on open source technology.  ARToolkit is the first fully-featured toolkit for marker-based AR  It has the advantage to be easily affordable but sometimes it is not supported and fairly weak  Total Immersion provides the world’s most widely used commercial augmented reality platform. TYPES OF AUGMENTED REALITY
  14. 14. MARKER LESS TRACKING  This is currently one of the best technology for tracking  It performs active tracking and recognition of real environment on any type of support without using special placed markers.  Allows more complex applications of Augmented Reality.
  15. 15. GPS and Compass Technology :  Found in smartphones and tablets  Uses devices' GPS, compass features and high-speed wireless networks Allows more complex applications of Augmented Reality. Main Attraction: Limitation:  Provides useful local web-content information and added services in 2D format at the geo-location of the user  Fairly imprecise due to current inaccuracy of the GPS technology
  16. 16. Used in Aircraft
  17. 17. Used in Movies
  18. 18. Medical Applications • A research team used Augmented Reality to cope with a 25-year-old woman’s cockroach phobia. Virtual cockroaches were displayed on the woman’s hands. After some sessions, her phobia for cockroaches has been eliminated.
  19. 19. Characteristics of AR It combines real and virtual World It is interactive in real time It is registered in 3D.
  20. 20. Hardware needed for AR….  Display  Tracking (GPS, compass)  Input devices (Camera)  sensors (accelerometer)  processer (CPU, any operating system or software)
  21. 21. GOOGLE GLASS  Google Glass is a wearable computer with an optical head mounted display (OHMD). It was developed by Google.  Using Augmented Reality Technology.
  22. 22. EARTHMINE  Company uses vehicle mounted camera.  Capture imagery and three dimensional data.  Get information from GPS  intelligent software.
  23. 23. Zugara Online Shopping
  24. 24. Advantages of AR AR Improve interaction Advances in technology Military Trainings which could be less expensive Rapid augmentation in tourism. Effective in Medical Field. Easy to locate desired places. A Good way of teaching. Increased the learning abilities.
  25. 25. Disadvantages of AR o Three dimensional, real-time running augmented reality programs like "first person shooters" have been believed to increase teen aggression because they normalize violence. o The lack of privacy. o Difficult to maintain Augmented Reality Systems. o Augmented reality is leading to an era of no privacy, where criminals could simply point their phone at victims and learn anything they need to know about them.
  26. 26. • Google Glasses and Augmented ID or any other face detection application effect the privacy of humans.
  27. 27. CONCLUSION • Augmented reality (AR) is a way of delivering entertainment media that uses computer generated graphics transposed over real-life scenes. • Create a system such that User CANNOT tell the difference between the real world and the virtual augmentation of it. • To add information and meaning to a real object or place. • Use of Medical Application increased and save the life of humans. • But developers should controls the privacy. People thinks Augmented reality is leading to an era of no privacy, where criminals could simply point their phone at victims and learn anything they need to know about them.
