Abstract: Three key elements are included to analyze the essence of technological phenomenology in terms of media technology. They are relationship convergence， human intervention and information environment. Relationship convergence and human intervention are extracted from Borgmanns device paradigm. Information environment serves as the degree index of media shaping the media world， with the media world forming the juncture of Borgmanns device paradigm and Ihdes I-world phenomenology in media research. This paper uses the three key elements to explore the three nodes of media development and the trends of mobile Internet. It is pointed out that the technological phenomenology of mobile internet is based on the complete form of information technology device， which could create complete information environment anytime and anywhere independently.

Key words: mobile internet, phenomenological analysis, information enviorment, technological device
