Developing Mobile Physiological Sensor that Works with Indoor Positioning System
نویسندگان
چکیده
In this paper, we propose a mobile physiological sensor that works with an indoor positioning system based on a wireless sensor network. The physiological sensor is a small, mobile, multi-sensor device which includes electrocardiograph, 3-axis accelerometer, barometer, thermometer, and hygrometer. In addition, the device is a network node of a wireless sensor network and receives beacon signals from network nodes installed in an indoor space. Obtained physiological signals and Received Signal Strength Indication (RSSI) of the beacon signals are simultaneously recorded. Based on the data, user’s physiological statuses and trajectories in the space are estimated. We describe design and implementation of the mobile physiological sensor device and the indoor positioning system. Then experimental results of the system are shown.
