3. Mixed Reality: Blending Physical and Digital Worlds - How Does it Work?

Mixed reality bridges the gap between AR and VR, offering a more seamless integrate between the real and virtual worlds. Mixed reality not only overlays digital content but also allows virtual objects to interact with real objects in a way that feels natural and intuitive. This requires advanced sensor technology and compute power to accurately map the physical environment and anchor virtual elements within it.

Mixed reality is achieved through a combination of technologies, including:

• Advanced Sensors: Sensors are used to map the physical environment in real-time.

• Spatial Computing: Spatial computing enables virtual objects to understand and interact with the physical world.

• Advanced Display Technology: Advanced display technology presents virtual objects in a way that feels realistic and integrated with the real world.

The taxonomy of mixed reality visualizes this spectrum, with AR and VR as opposite ends and MR occupying the space in between, offering varying degrees of integration between real and virtual worlds.

4. What are Some Real-World Applications of Extended Reality XR?

The xr applications are vast and span across numerous industries. In healthcare, XR is used for surgical training, patient rehabilitation, and medical visualization.
