The purpose of a mixed reality headset is to merge the physical and digital worlds by allowing users to interact with both simultaneously. These devices create an immersive experience where digital objects can coexist and interact with real-world surroundings. Users can view and manipulate holograms while still being aware of their physical environment. This technology is commonly used in gaming, training simulations, and design applications, providing enhanced user engagement and creativity by enabling realistic interactions between physical and virtual elements.
