This question tests the understanding of the fundamental differences between Augmented Reality (AR) and Virtual Reality (VR). AR enhances the real world by overlaying digital elements, while VR creates a completely immersive simulated environment that replaces the physical world.
❌ Statement 1 – Incorrect: This describes VR, not AR. AR enhances the real world with digital overlays rather than shutting out the physical world completely.
❌ Statement 2 – Incorrect: This describes AR, not VR. VR creates a completely simulated environment that replaces reality, not projects images into real-life objects.
✅ Statement 3 – Correct: AR allows users to remain present in the real world while enhancing their experience through smartphones or PC cameras that overlay digital content onto real surroundings.
✅ Statement 4 – Correct: VR closes out the physical world and transports the user into a fully immersive simulated environment, typically through headsets.
