🏛️ Must Know
How AR and VR Are Actually Different
- AR Keeps You in the Real World Augmented Reality genuinely lets a person stay present in the real world. It enhances that world through a smartphone or PC camera.
- VR Fully Immerses You Virtual Reality genuinely closes off the real world, transposing the person into a fully immersive simulated environment.
- The Common Mix-Up AR does not shut out the physical world, and VR does not project images onto real-life objects. Those descriptions are actually swapped between the two.
- Correct Answer Only statements 3 and 4 are correct. The answer is 3 and 4.

How Each Technology Actually Works
- AR Overlays Digital Content AR overlays computer-generated images onto a live camera feed of the real world. A phone game showing characters on your actual floor works this way.
- VR Uses Headsets VR typically uses a head-mounted display that blocks external visuals and sound, replacing them entirely with a simulated scene.
- Both Rely on Sensors Both AR and VR track a user’s head or device movement using sensors, adjusting the display in real time to match.
