Features of MR technology.

Feature	Specific performance
Reality	MR can combine virtual and reality to create an immersive feeling. The experiencer feels a new environment that is half real and half virtual to produce a good sensory experience [21].
Conceptuality	In a realistic new environment, users use their imagination to construct an environment that does not exist objectively. MR technology has a very large room for development. MR will continue to enrich the interactive display technology of images in digital exhibition halls with the continuous development and improvement of technologies such as computers and VR [22].
Interactivity	MR technology combines VR with traditional physical displays, building a bridge between virtual objects and the real world. A connection between users and physical objects is established. Users can move freely between reality and VR, change the traditional static display state, and break the one-way nature of information transmission to realize real-time interaction and communication between people and objects [23].
