摘　　要：上下文感知是在移动计算环境中实现人机自然交互的关键,该文分析在信息空间和物理空间融合环境中,上下文应具有的意义、特征和作用。结合RFID技术的特点和发展趋势,提出通过基于RFID与移动计算获取上下文以进行智能交互的思想。采用被动式RFID标签跟踪并存储上下文数据,以蓝牙作为无线交互信道,结合移动终端PDA实现嵌入式系统,通过实验给出应用效果。该原形系统在可穿戴计算、医疗看护、残障协助和路标导航等方面具有实验推广价值。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.
