VR closes the world, and transposes an individual, providing complete immersion experience.<br/><br/>Which of the statements given above is/are correct?
Answer
3 and 4
1. Incorrect. This describes Virtual Reality (VR), not AR. In AR, the real world remains visible and digital elements are overlaid on it.
2. Incorrect. This describes Augmented Reality (AR), where computer-generated images are superimposed on real surroundings. VR instead creates a fully immersive virtual environment.
3. Correct. AR keeps the user in the real world and enhances it using devices like smartphone cameras, tablets, or PCs.
4. Correct. VR shuts out the physical world and places the user in a completely immersive simulated environment.
Hence, statements 3 and 4 are correct.
