  1. AugmentedReality Linking Real and Virtual Worlds
  2. What is Augmented Reality or AR ? A live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics or GPS. As a result, the technology functions by enhancing one’s current perception of reality.
  3. What is Augmented Reality or AR ? • AR can maintain the high-level of detail and realistic shading that one finds in the real world. • A combination of – a real scene viewed by a user and – a virtual scene generated by a computer that augments the scene with additional information.
  4. What is Virtual Reality or VR??? Computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds. Virtual reality replaces the real world with a simulated one.
  5. AR vs VR VR: the user is completely immersed in an artificial world and becomes divorced from the real environment. The generated world consists entirely of computer graphics. an AR system is augmenting the real world sense of presence in that world. The virtual images are merged with the real view to create the augmented display. A main motivation for the use of AR relates to the computational resources necessary to generate and update computer-generated scene. In VR, The more complex the scene, the more computational resource needed to render the scene.
