Abstract
This paper introduces a crowdsensing approach to identify the points of interest (POI) among the elderly population in Singapore. We have developed a smartphone application, which passively collects sensors' information (e.g. GPS location) on users' mobile devices. Using such information, we can identify popular regions and places among the elderly that could be useful for city planner in preparation for aging population. Our results demonstrate different check-in patterns of various POI, and the elderly spend nearly 70% of nonhome duration around their neighborhood.
