UbiSense - Ubiquitous Sensing and Behaviour ProfilingThe UbiSense project aims to provide an unobtrusive health monitoring system for the elderly using embedded smart vision techniques to detect changes in posture, gait and activities. To analyze the subjects activity, subject specific information called "personal metrics" are gathered by tracking the following features in image sequences:
The personal metrics can be transmitted between sensors so that complex behaviour profiling can be
performed by utilizing resources of other UbiSense nodes in the network. |

A simulated house set up with a network of UbiSense system is illustrated in fig.2. Considering the fact that behaviour profiling involves a set of highly demanding computa-tional tasks that typically require expensive hardware and sophisticated setup procedure, the UbiSense pro-ject investigates the use of a networked low cost embedded smart video sensors to provide complex behav-iour profiling functions based on resource scavenging, dynamic clustering and self-configurations |

UbiSense NodeA prototype UbiSense node is designed with an em-bedded smart camera VCSBC50 (a DSP camera), a wireless link provided by an integrated BSN node, and a battery, as shown in Fig.3. The BSN node is a miniaturized (26mm) generic wireless sensing platform for context aware sensing environments. With its compact design (10x7x6cm), the UbiSense node can be installed easily by the user. |
