From Imaging Networks to Behavior Profiling: Ubiquitous Sensing for Managed Homecare of the Elderly

With demographic changes of the aging population and the increasing number of people living alone, pervasive home monitoring is set to play an important role in maintaining the independence and improving the quality of life for the elderly. The UbiSense† project aims to establish smart sensing networks based on low cost embedded video platforms for movement tracking and gait, posture analysis. To ensure privacy, the captured images in UbiSense are immediately filtered at the device level into blobs, which only encapsulate the shape and motion vectors of the subject so that no visual appearance of the subject is ever used. This demonstration will outline the concept of “from blob to personal metrics to behaviour profiling”, and illustrate the latest hardware platform and software implementation of the UbiSense design.
