Virtual Reality, commonly called VR, is a technology that creates a simulated environment using a computer. Instead of watching a screen, you are inside the experience. VR replaces the real world with a virtual one often 3D and interactive.
Using a headset like the Meta Quest 3 or HTC Vive, you can explore virtual worlds, play games, watch movies, or even practice surgeries all without leaving your room.
Unlike Augmented Reality (AR), which adds digital elements to the real world (like filters or holograms), VR completely immerses you into a different world.
🎮 How Does Virtual Reality Work?
Virtual reality works using a combination of hardware and software. Here’s a simple breakdown:
1. Headsets
These are wearable devices that cover your eyes and ears. They include:
- Meta Quest 3
- PlayStation VR2
- HTC Vive Pro 2
2. Sensors & Trackers
These track your head, eye, and body movements. When you look or move around, the VR world moves with you just like real life.
3. VR Software
This is the app or game running in the headset. It creates the digital environment you see. Some popular platforms:
- SteamVR – for PC-based VR games
- Oculus Store – for Meta devices
- Viveport – HTC’s VR content platform
