Research on the context model of intelligent interaction system in the Internet of Things

Context model is a fundamental issue when the intelligent interaction system is constructed based on context-aware in the Internet of Things. In the traditional interaction system of the user-centric and human-computer interaction oriented, the main context is users and their surrounding's information. However, in the Internet of Things of the thing-thing interaction, the main context will be changed to the perception nodes and their surrounding's information. But, there is not a unified context model aiming at this point. This paper presents a context model and analyzes the conception, classification and formalization of the context. Therefore, this work can have been an important instructing meaning and direct effect on constructing the intelligent interaction system in the Internet of Things. © 2011 IEEE.
