Intelligent Interaction System Based on Context Awareness and RFID

Context awareness becomes the key technology in the human computer interface of mobile computing.This paper discusses the characteristic,significance and function of the context in the environments where the physical space fuses with the information space.It presents a method to realize context aware and the wireless interaction by using the pervasive RFID tags to track the context and using Bluetooth as the contactless communication measure.It also constructs a prototype system composed of RFID tags,BTEnableReaders and Bluetooth-enable mobile terminals.One case of application scenario is given and the experimental results show that the performance and robustness of devices are suitable for ubiquitous applications.The devices can be extended to other application areas such as wearable computing,health care,disable help,road navigate.
