Wearable health care devices, gadgets for monitoring personal activity including  steps to heart rates, are gaining popularity on health-care and sport fields. Consequently, precise analysis of the health and physical performance of the individual is promising.

In contrast, our research focuses on expanding the data analysis from “individual(s)” to “groups” and “communities”.

As a first step of the data analysis for “group” level analysis, we developed a method to detect people moving around together by using only the step tracking data acquired from smart pedometers like Fitbit. From  the step data collected in our evaluation, we confirmed that working-relationships can be visualized by detecting people moving around.
