Question 91

Let's differentiate between Augmented Reality (AR) and Virtual Reality (VR):

1. In Augmented Reality (AR), a simulated environment is created and the physical world is completely shut out. This statement is incorrect. This describes Virtual Reality (VR), where the user is immersed in a completely simulated environment, effectively shutting out the physical world.

2. In Virtual Reality (VR), images generated from a computer are projected onto real-life objects or surroundings. This statement is incorrect. This describes Augmented Reality (AR), where digital information or images are overlaid onto the real physical world, enhancing it.

3. AR allows individuals to be present in the world and improves the experience using the camera of smart-phone or PC. This statement is correct. AR applications use the device's camera to capture the real environment and then overlay digital content (images, information, 3D models) onto it, allowing the user to interact with both the real and virtual elements simultaneously.

4. VR closes the world, and transposes an individual, providing complete immersion experience. This statement is correct. VR systems aim to provide a fully immersive experience by creating a simulated environment that replaces the user's real surroundings, often through head-mounted displays that block out external visuals and sounds.

Therefore, statements 3 and 4 are correct.
