Abstract: Metaverse technology aims to establish the connection between the real world and the virtual world. With the development ofInternet technology and artificial intelligence technology, the metaverse has become a new upstart in scientific and technological research field. The authenticity and validity of the metaverse depend on whether it can stimulate the true feelings in human-computer interaction process. However, at present, the metaverse can only simulate the real world from the objective facts, and the research on emotion and value is significantly insufficient. Therefore, its emotional weakness has become the bottleneck of the further application of the metaverse in military intelligence. This paper focuses on the problems of emotion and affection of the metaverse, the classic research of emotion and affection is sorted out, and a theoretical basis for the research of emotion and affection of the metaverse is provided. Furthermore, the emotional interaction of the human-autonomous system to that of the metaverse is extended and a new interaction model between the real world and the metaverse is proposed. Finally, two important technical supports for studying emotion and affection in the future metaverse are discussed and the new vision of the close combination of the metaverse technology and military technology are prospected to support the in-depth application of metaverse from theoretical research to the practical practice.
