Augmented Reality (AR):
- Layers computer-generated enhancements over reality, enhancing real-world experiences.
- Examples: Snapchat lenses, Pokemon Go.
Virtual Reality (VR):
- Creates a realistic, immersive simulation of a 3D environment, experienced through body movement.
- Examples: VR on PS5, Meta Quest.
Mixed Reality (MR):
- Blends real and virtual worlds, allowing users to interact with both.
- Examples: Microsoft’s Hololens, Vision Pro by Apple.

AR vs. VR:
- AR integrates with the real world; VR creates an entirely virtual experience.
- AR allows user control in real-world settings; VR is controlled by the system.
- AR can be accessed via smartphones/tablets; VR usually requires dedicated headsets.
AR vs. MR:
- MR is an advanced form of AR, integrating virtual objects into the real world.
- Users can interact with virtual elements as if they are part of their environment.
