Question 59 from UPSC CSE 2019 - Science & Technology

Question

In the context of digital technologies for entertainment, consider the following statements:
1. In Augmented Reality (AR), a simulated environment is created and the physical world is completely shut out.
2. In Virtual Reality (VR), images generated from a computer are projected onto real-life objects or surroundings.
3. AR allows individuals to be present in the world and improves the experience using the camera of smartphones or PC.
4. VR closes the world, and transposes an individual, providing a complete immersion experience.
Which of the statements given above is/are correct?

IASCODEX · Accepted Answer

Correct Option: B. 3 and 4

Strategy: Carefully differentiate between AR and VR using their defining features. Statement 1 incorrectly describes AR as shutting out the physical world, which is actually a property of VR. Statement 2 describes overlaying computer images onto the real world, which is the principle of AR, not VR. On the other hand, Statement 3 accurately captures AR by highlighting enhancement of real-world experience via device cameras. Statement 4 correctly represents VR by emphasizing total immersion, separating the individual from the real world. Eliminate misattributed properties to arrive at the correct set.

Key Info: Augmented Reality (AR) is a technology that overlays digital information, such as images, sounds, or other data, onto the physical real-world environment, enhancing a user's perception of reality. The user remains aware of and interacts with their physical surroundings, typically via smartphones, tablets, or specialized AR glasses (e.g., Google Glass). AR uses camera feeds and sensors to superimpose computer-generated content.

Virtual Reality (VR), in contrast, completely immerses users in a simulated, computer-generated environment that shuts out physical reality. Users wear VR headsets (such as Oculus Rift, PlayStation VR, HTC Vive) that replace their real-world view entirely with digital visuals and sounds, resulting in a sense of 'being inside' an artificial world.

Key differences:
- AR: Enhances real world; user stays present in reality; uses cameras/displays to mix digital and real environments. Examples: Pokemon Go, Snapchat filters.
- VR: Substitutes real world with a digital one; user is immersed and isolated from the actual environment; needs dedicated headset/console. Examples: VR games, VR simulations.

Wrong statements:
- Statement 1 incorrectly assigns VR's property (full immersion) to AR.
- Statement 2 swaps AR's overlay principle with VR, which is inaccurate.

Correct statements:
- Statement 3: Highlights AR keeping users in the real world and leveraging device cameras for enhancement.
- Statement 4: Accurately describes VR's total immersion and transposition effect.
