In the study of communication, the relationship between body and technology has gone through the development process from separation to embodiment. In the past, the media technology was regarded as the extension of the body in the aspect of tool theory. Nowadays, human experience relies more and more on the relationship between technology media and the world. The body communication is not only the change of technology to the body experience, but also reveals the existential transformation of media technology from the relationship between human, technology media and the world. The material form and information content of media constitute the background and prospect of human social activities: on the one hand, people's living experience is based on the pre understanding created by the media environment; on the other hand, people have to rely on the media to understand and plan future living activities. Media technology has gradually become a necessary condition for people to understand society, interpret information and make decisions. The interactive generation of human and media makes media technology gradually become an artifcial limb and "the third hold" of human beings, and become an indispensable part of human consciousness and living experience.
