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 smart-phone or PC.
4. VR closes the world, and transposes an individual, providing complete immersion experience.

Which of the statements given above is / are correct?

Let's clarify the difference between Augmented Reality (AR) and Virtual Reality (VR).

Augmented Reality (AR) enhances the real world by overlaying computer-generated information onto it. AR uses devices like smartphones or PCs to improve the user's experience of the real world, allowing them to remain present in their surroundings.

Virtual Reality (VR) creates a completely simulated environment, immersing the user and shutting out the physical world. VR transposes individuals into a digital world, providing a complete immersion experience.

Therefore:

• Statement 1 is incorrect: This describes VR, not AR.
• Statement 2 is incorrect: This describes AR, not VR.
• Statement 3 is correct: AR enhances the real world and uses devices like smartphones.
• Statement 4 is correct: VR provides a completely immersive experience.

Hence, statements 3 and 4 are correct.
