MIT researchers recently built an augmented reality headset called X-AR that lets users see hidden objects inside a box or under a pile.


About Augmented Reality (AR)

  • It is an enhanced version of the real physical world that is achieved through the use of digital visual elements, sound, or other sensory stimuli and delivered via technology.
  • It overlays digital content onto real-life environments and objects.
  • AR works by superimposing digital information onto real world objects to create a 3D experience that allows users to interact with both the physical and digital worlds.
  • It incorporates three features — a combination of digital and physical worlds, interactions made in real time, and accurate 3D identification of virtual and real objects.
  • Unlike Virtual Reality (VR), which creates its own cyber environment, AR adds to the existing world as it is.


What is Virtual Reality (VR)?

  • It is a simulated 3D environment that enables users to explore and interact with a virtual surrounding in a way that approximates reality as it is perceived through the users’ senses.
  • The environment is created with computer hardware and software, and the users need to wear devices such as helmets or goggles (Virtual Reality headsets or helmets) to interact with the environment.
