multimodal archiving, real-time annotation and information visualization in a biofeedback system for stroke patient rehabilitation
In this paper we present our work on a system to support real-time multimodal archiving, collaborative annotation and offline information visualization for a biofeedback stroke-rehabilitation application. Our archiving / annotation / visualization system can play a critical role in the long-term biofeedback stroke therapy by supporting cooperative data analysis and media feedback as well as by providing the therapist with insight into computing-supported therapy. There are three contributions of this paper: (a) the design of a robust archiving system that archives in real time parametric model data (motion capture, motion analysis and audio / visual synthesis parameters) as well as audio / video from the biofeedback environment. (b) a web-based annotation tool designed with low cognitive load (c) a hierarchical information visualization tool that enables the therapist and other team members to examine quantitative motion analysis of subject performance with the context of media feedback, thus enabling collaborative insights. Our user studies indicate that the system performs well.
