Mediums of information transfer around the world are diverse. However, as the simplest interface, human bodies are usually ignored. The human body can easily deliver various information to outside. Here, the purpose of this paper is to investigate how the significant factors of technology and visual culture enable the human body to express relevant information about them. This article will do literature review, analyze some experiments and a lot of media records like photos experiment data, and movies. Advanced technologies are also introduced and used in this paper. This article reveals that human bodies can be an interface of information exchange. First, humans' nervous system can be analyzed by the latest equipment which can detect brain activities. These records offer content about people's thoughts and ideas, which means the nervous system of a human reflects the information. In the next part, this paper will concentrate on cell phones. A lot of pictures and photos on the Internet in cell phones are able to show different information like jobs and identity. Finally, diverse types of scenarios, lens, and environments in VR glasses and science fiction involved in horrible scenes can easily change people's behaviors and responses. Thus, the result consists of the evidence that is used. The paper is helpful to people who want to research different functions and connections between the human body and visual culture.
