Abstract: Human life has a growing demand for communication technology and interpersonal communication， therefore， is concerned by scholars. Through some important functions （including interactive communication management and own communication management）and processes involved in faceto - face communication， communication content， orientation， and dynamic system can be examined.Multimodal communication means several perceptive and productive models jointly，simultaneously，and continually activate，share，and build information. Communication，language，and culture are defined through a description of some most important factors that affects human communication （social activity，personality，and national-ethnic culture）. This paper analyses the dynamic response between the content of communication and dialogue and presents a embodied communication model which involves several levels of awareness and intentionality（directive，expressive，signal）. A discussion of the relation between face-toface communication and communication technology finds that communication technology enables human beings to go beyond the spatial and temporal barriers but at the same time causes a loss of the rich spatial and temporal presence.

Key words: multimodal, human communication, face-to-face communication, intentionality, communication technology
