Adjust the real world around your work environment to include critical 3D imagery and help train new providers, teach patients or perform better in the OR. 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 (MR), 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 world.
