Virtual Reality

Subject: Science and Technology

In news: Indian Institute of Technology Madras has launched the country’s first consortium for Virtual Reality called ‘Consortium for VR/AR/MR Engineering Mission in India’ (CAVE).

About CAVE:

  • It aims to become a resource for industry, academia, consumers, and policy makers interested in virtual, augmented, and mixed reality.
  • The key outcomes envisaged from CAVE include developing indigenous VR/AR/MR and ‘haptics’ hardware and software; set up ‘VR Superhighway’ or ‘VR Corridor’ where many start-ups and industries work together for a bigger mission to make India the choice for future XR and ‘haptics’ needs.
  • Centre of Excellence on Virtual Reality and Haptics at IIT Madras has been set up under the ‘Institute of Eminence’ Initiative.

Extended reality

  • Extended Reality (XR) is an umbrella term encapsulating Augmented Reality (AR), Virtual Reality (VR), mixed reality (MR), and everything in between.

Augmented Reality (AR)

  • An enhanced version of reality where live direct or indirect views of physical real-world environments are augmented with superimposed computer-generated images over a user’s view of the real-world, thus enhancing one’s current perception of reality.
  • Various filters on Snapchat and Instagram are an example of Augmented Reality.
  • Gaming –Pokemon is one of the most famous games to hit a big chord with the public.

Virtual Reality (VR):

  •  It can be referred to as immersive multimedia or computer-simulated reality which replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact in that world.
  • Images created by a computer that appear to surround the person looking at them and seem almost real are said to be virtual reality.
    • On the other hand Augmented reality is the real-time use of information in the form of text, graphics, audio, and other virtual enhancements integrated with real-world objects.

Mixed reality (MR):

  • It can be referred to as hybrid reality that is the merging of real and virtual worlds to produce new environments and visualisations where physical and digital objects co-exist and interact in real time.
  • Microsoft’s Hololens is a well-known example of an existing, commercially available Mixed Reality device.

  • Integrates text, graphics, audio, and adds value to the users’ interaction with the real world.
  • Transparent screen
  • AR does not replace the actual world environment with 3D digital elements.
  • Simulation of Reality
  • Opaque screen
  • VR replaces the actual world environment with 3D digital elements
  • VR is a completely computer-generated three-dimensional environment that is displayed either on a computer screen or through special displays.
  • It is a combination of AR and VR, allows a person to see and immerse oneself in the real world while simultaneously interacting with the virtual environment using hands.
