xR experiences persist in the real world across space, time and rendering devices and enable what are often called ambient environments and ambient computing. Incorporating the context of the real world (such as the 3D of the real world), can be critical to blending virtual and real together. An xR experience can change based on different dimensions such as mood, environmental context, and time of day.
Augmented Reality (AR) is a technology that layers computer-generated enhancements atop an existing reality in order to make the reality more meaningful and interactive. AR may be developed into apps and used on mobile devices to blend digital components into the real world in such a way that they enhance one another. AR may be used to display score overlays on telecasted sports games and pop out 3D emails, photos or text messages on mobile devices. AR may also incorporate holograms and motion activated commands.
Virtual reality (VR) is an artificial, computer-generated simulation or recreation of a real-life environment or situation. It immerses the user, making them feel like they are experiencing the simulated reality firsthand, primarily by stimulating their vision and hearing. VR may be achieved by wearing a headset equipped with the technology.
VR may be used to create and enhance an imaginary reality for gaming, entertainment, and play (such as video and computer games, or 3D movies, head mounted displays). It may also be used to enhance training for real-life environments by creating a simulation of reality where people can practice beforehand (e.g., flight simulators for pilots).
