Sign language, as the main means of communication used by hearing-impaired people, is an indispensable part for them to better integrate into a harmonious society. At the same time, the all-round development of today's society urgently needs to build a bridge for the hearing impaired to communicate with the society, create a barrier-free environment, and increase the degree of socialization of the hearing impaired. All these factors promote the demand for direct human-computer interaction in sign language. This paper aims to explore the electromagnetic representation and interpretation of sign language semantics, hoping to provide a new way to improve the level of human-computer interaction and care for the hearing impaired.
