The goal of the Metaverse is to realize the informationization and intelligence of all things,
to create a virtual and real fusion space where information fully surrounds people,
and to evolve into a new social form with no boundaries between time and space.
Therefore, the interaction technology of the Metaverse is particularly important.
The interaction methods in the metaverse include voice interaction,
gesture interaction, smell, touch, brain-computer interface, etc.,
but a single interaction method can only achieve partial immersion,
and multi-modal fusion interaction methods can ensure the full-scene interactive experience.
VR, AR, MR, XR and other devices can be regarded as the key to open the door of the metaverse.
By establishing a body surface wearing aid for the interaction between the human body and the sensor recognition technology, the immersive environmental space can be used to use vision, hearing, touch, etc.
Sensory elements convey the presence of the real world and realize the interaction between reality and virtuality.
