Why in news?

  • Researchers have found that virtual reality (VR)—a computer-generated simulation of a three-dimensional image or environment usually experienced using head mounted displays (HMDs)—may interfere with visual memory, a finding that may lead to better application of the technology.
  • They speculate that the enhanced sense of realism and immersion created by the ability to look around freely, tires the brain and consequently prevents the formation of visual memory.
  • In further studies, the research team hopes to find out why visual memory is hindered when the participants can look around freely in VR.

Background:

What is Augmented Reality-

Augmented reality is the blending of virtual reality and real life, as developers can create images within applications that blend in with contents in the real world. With AR, users are able to interact with virtual contents in the real world, and are able to distinguish between the two. The best example of AR can be – ‘Pokemon Go’.

What is Virtual Reality-

Virtual reality is all about the creation of a virtual world that users can interact with. This virtual world should be designed in such a way that users would find it difficult to tell the difference from what is real and what is not. Furthermore, VR is usually achieved by the wearing of a VR helmet or goggles similar to the Oculus Rift.

Difference and similarities-

Both virtual reality and augmented reality are similar in the goal of immersing the user, though both systems to this in different ways. With AR, users continue to be in touch with the real world while interacting with virtual objects around them. With VR, the user is isolated from the real world while immersed in a world that is completely fabricated. As it stands, VR might work better for video games and social networking in a virtual environment, such as Second Life, or even PlayStation Home.
