Augmented Reality (AR) & Virtual Reality (VR)

AR and VR are immersive technologies that blend the physical and digital worlds.

Virtual Reality (VR)

Definition: Creates a fully immersive, simulated environment that replaces the user's real-world view. Users typically wear head-mounted displays (VR headsets).

Characteristic: Full immersion, cuts off real world.

Examples: Meta Quest, HTC Vive, PlayStation VR.

Augmented Reality (AR)

Definition: Overlays digital information (images, videos, 3D models) onto the user's view of the real world. It enhances the real world with virtual elements.

Characteristic: Blends real and virtual, doesn't cut off real world.

Examples: Smartphone AR apps (Pokémon Go), AR glasses (Google Glass, Microsoft HoloLens).

Key Differences: AR vs. VR

Feature	Virtual Reality (VR)	Augmented Reality (AR)
Immersion	Fully immersive	Less immersive, blends
Real World Integration	Replaces real world	Augments real world
Hardware	Typically requires headsets	Smartphones, tablets, or glasses

Applications & Market Trends

Applications:

Gaming & Entertainment (Immersive VR, Interactive AR)
Education & Training (Virtual labs VR, Interactive learning AR)
