Interactive data visualization could be beneficial to gain insight into the data concerning the inhabitant and the environment collected by an ambient assisted living system. In this paper we present BRIDGeViz that is a web-based interactive visualization tool for the BRIDGe AAL system. It is an effort to help caregivers, the main target users, to explore the daily life dynamics of the inhabitant in order to detect life trends, deviation from daily norms, and search for potential causes of a problem. BRIDGeViz provides two main views and visualizations: the overview visualization for a holistic view of long-term data and the detailed view for a day-level detailed exploration. The visualizations are enriched by interaction mechanisms and some analytic support such as searching for similar days. We also conducted a user study with a demo version of our tool with a positive overall feedback.
