What is virtual reality ?
Virtual reality (VR) typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real environment or create an imaginary setting. VR also simulates a user’s physical presence in this environment. VR has been defined as “a realistic and immersive simulation of a three-dimensional 360-degree environment, created using interactive software and hardware, and experienced or controlled by movement of the body” or as an “immersive, interactive experience generated by a computer”.
What is Augmented reality ?
Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.By contrast, virtual reality replaces the real world with a simulated one. Augmentation is conventionally in real time and in semantic context with environmental elements, such as sports scores on TV during a match.
