MR integrates both the physical and digital realms, enabling virtual content to interact believably with the real environment and allowing the user to engage with both the digital and physical elements simultaneously.

This rigorous requirement necessitates advanced sensor fusion and tracking (SLAM) to create a persistent, stable anchoring of virtual objects within real space.

For example, a digital hologram can sit on a real table and be manipulated with your hands. MR is often used for technical training, design visualization, and on-site remote guidance.
