Abstract :
This paper presents a design and implementation of a location-aware service system, which combines a radio-frequency-based positioning engine and a multimedia human-machine interface (HMI). In this system, a number of Zigbee sensors are deployed for the localization purpose. Users´ locations can be estimated according to their received signal strength samples from the Zigbee sensors. In order to improve the positioning efficiency, a hierarchical positioning architecture is proposed. The multimedia HMI is to help users to access the provided services. A speech recognition system is designed as the input of the system and a visualization system has been developed as the output interface of the location-aware system. Moreover, the visualization service is integrated with the open service access (OSA) platform via mobile network systems. The whole system can be directed to future homecare applications.
