Virtual reality (VR) is a way of using computer technology to create a simulated, three-dimensional world that a user can manipulate and explore, while feeling as if he or she were actually in it themselves. By using a headset to immerse the user completely, VR experiences use sight, hearing, touch, and smell to transport users into a truly alternate reality.
Augmented reality (AR) is a way of overlaying virtual information on top of the real world, primarily viewed through the camera display of a mobile device or wearable technology. Through graphics, sound, and sensory feedback, AR blurs the line between what is real and what is not, by enhancing what we see, hear, feel and smell.
The uses of virtual and augmented reality are diverse and increasingly widespread. Through mobile devices, VR headsets like the Oculus Rift, HTC Vive, and Google Cardboard, everyone from big business, to medical professionals and gamers, to consumers, from soldiers to students, and tourists are utilizing the technology to enhance the way that we all work, live, and play.
