Mixed reality 

 

 

EXPLANATION

Mixed reality (MR) not just overlays, but anchors virtual objects to real-world objects and allows the user to interact with combined virtual/real objects.

• Virtual reality (VR) immerses users in a fully artificial digital environment.
•   Augmented reality (AR) overlays virtual objects on the real-world environment with spatial registration that enables geometric persistence concerning placement and orientation within the real world. Prior technologies that overlaid data or images not spatially registered to real-world geometries are referred to as heads-up display technologies.
