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

The correct answer is B. Statements 3 and 4 are correct.

• Statement 1 is wrong. It describes VR, not AR. Augmented Reality layers digital content over the real world and keeps the user anchored in their surroundings. VR is the one that shuts out the physical world.
• Statement 2 is wrong. It describes AR, or projection-mapping, where computer-generated images sit on real objects. In VR, the user is placed inside a fully simulated environment.
• Statement 3 is correct. AR works through a smartphone or PC camera, letting the user stay in the physical world while the experience is enhanced, as in Pokemon Go or retail try-on apps.
• Statement 4 is correct. VR, through headsets, closes off the external world and gives complete immersion.

The core concept is the difference between immersion and overlay. The same distinction matters in Mains for emerging technology questions, such as privacy concerns from always-on AR cameras and the need for data protection law.

Trap: Aspirants often swap the AR and VR definitions because both appear in similar language. Ask one question: does the user still see the real world? If yes, it is AR; if no, it is VR.
