Mixed Reality represents the most sophisticated form of XR, creating a hybrid environment where physical and digital objects coexist and interact in real-time. Unlike AR (which just overlays content) or VR (which replaces reality), MR allows digital elements to respond to and be occluded by the physical environment.
Key Characteristics
Spatial Awareness
- Devices map and understand the physical environment
- Digital objects can be placed on real surfaces (tables, walls, floors)
- Virtual content respects physical boundaries and obstacles
Real-Time Interaction
- Users can manipulate digital objects with natural gestures
- Physical objects can affect digital ones and vice versa
- Collaboration between remote users in shared spaces
Persistent Content
- Digital objects remain anchored to physical locations
- Return to a space and find virtual content exactly where you left it
