Virtual Reality (VR)
Virtual reality is the term used to describe a three-dimensional, artificial (computer generated) environment which can be explored and interacted with by an individual. Through using special Virtual Reality hardware, this "virtual environment" feels realistic to the user and in many ways they experience it as they would a real environment. Whilst there, they are able to interact with their surroundings, manipulate objects or perform a series of actions. Virtual reality is primarily experienced through two of the five senses: sight and sound, although sometimes also incorporates touch and motion.
Augmented Reality (AR)
Augmented Reality is the process of superimposing digital information or images onto our real-world surroundings, giving a sense of a virtual illusion. Augmented reality integrates digital information, photographs or 3D models with the user's environment in real time. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it. This technology can be used to enrich the user's real world experience with digital information and educational media about a particular location, site or, product. Recent developments have made this technology easily accessible using a smartphone or tablet.
