What Is Virtual Reality (VR)?
Virtual Reality (VR) refers to a fully immersive digital experience that replaces the user’s real-world environment with a simulated one. Using devices like VR headsets and motion controllers, users can explore and interact with 3D environments in real-time.
Key Features of VR:
- Completely immersive experience
- Requires headsets (e.g., Oculus Rift, HTC Vive, Meta Quest)
- Often used for gaming, simulation, and training
- User is isolated from the real world
Examples:
- Playing a game inside a virtual battlefield
- Practicing surgery in a virtual operating room
- Touring a 3D replica of a museum
What Is Augmented Reality (AR)?
Augmented Reality (AR) overlays digital content (like images, sounds, or data) onto the real world through smartphones, tablets, smart glasses, or AR headsets.
Key Features of AR:
- Real-world view enhanced with digital overlays
- Uses mobile devices, AR glasses, or cameras
- Common in mobile apps, retail, education
- User sees both real and virtual elements
Examples:
- Pokémon GO (game)
- IKEA Place (furniture visualization app)
- Snapchat filters
- AR surgery assistance tools
