Virtual reality

The term ‘Virtual reality’ appears in news very often and hence it becomes an important topic under GS3 – Science and Technology, developments and applications.

  • Virtual reality is the next big thing in the gaming and entertainment industry.
  • It is more advanced than 3D film technology.

3D film technology

2D vs. 3D
  • What you see on your laptop or mobile screen is a 2D image.
  • What your eye sees in your room is a 3D image.
3D photography or stereoscopic photography

2d vs. 3d video

  • It is the art of capturing and displaying two slightly offset photographs to create three dimensional images.
  • Most stereoscopic methods present two offset images separately to the left and right eye of the viewer.
  • These two-dimensional images are then combined in the brain to give the perception of 3D depth.  [View this gif: http://goo.gl/IC5pHb]
  • 3D film technology relies on such stereoscopic photography to give a 3D feel.

Virtual reality

  • Virtual reality (or VR) is a computer technology that uses software-generated images, sounds and other sensations to replicate a real environment.
  • A person using virtual reality equipment is typically able to look around the artificial world, move about in it and interact with features or items that are depicted.
  • Virtual realities artificially create sensory experiences, which can include sight, touch, hearing, and, less commonly, smell.

  • Mixed reality (MR) is the merging of real and virtual worlds where physical and digital objects co-exist and interact in real time.

3D == You can only see a 3D world = Sharukh Khan appears as if he is standing in front of you.

Virtual Reality == You can feel a 3D world = You can talk and dance with Sharuk Khan.

Merged Reality == You can combine real and fake 3D worlds = You can bring Sharukh Khan (virtual) to your room (real).

Inflation Trend

  • The annual gain in wholesale prices hit a 23-month high of 3.55 per cent in July.
  • Retail inflation went past the Centre’s new Monetary Policy Framework’s upper limit for tolerance to 6.07 per cent.
  • Food costs — a key component in both indices — were the main culprit.
  • Inflation in the food category of the CPI accelerated to 8 per cent, and in the case of the WPI surged to a 31-month high of 11.8 per cent.

Factors that are expected to affect Inflation in near future

  • Forecast of normal rainfall, and the improvement in sowing are expected to reduce supply side stress. [Inflation could fall]
  • But beneficial monsoons on the other hand can result in an uptick in rural wages, and by extension demand-side consumption pressures. [Inflation could rise]
  • According IMF working paper, rising real rural incomes have had the largest impact on food inflation. [Prelims point]
  • Robust real income growth has tended to translate into substantial demand-side pressures that far outpace the supply-side gains.
  • Domestic consumption continues to be a key engine of economic momentum.
  • Implementation of the Seventh Pay Commission’s recommendations and the One Rank One Pension plan will increase demand-side pressures. [Inflation could rise]
  • The Centre will have its task cut out in maintaining fiscal discipline if it is to ensure that increased expenditure from its side doesn’t end up fanning inflation.
