Crew Activity Analyzer

Foster-Miller proposes to develop the Crew Activity Analyzer (CAA) to provide NASA with an innovative and cost-effective method for efficiently analyzing individual and group crew activities, space usage, and other events of interest to NASA human factors analysts. The CAA consists of a compact and portable data acquisition system providing the ability to systematically capture video and other sensor data from a field site, (both IVA and EVA) for long durations, and an offline processing component that analyzes the acquired data. The CAA uses vision and sensing technology to identify user selected crew activities and spatiotemporal events from other detected events. These events are specified according to people, and spatial features (objects, and fixtures), time of day, etc. Events are recognized by temporal modeling of the observed motion and maintaining models of the expected motion associated with the user selected events. Phase II research will extend the successful Phase I work on image data to development of a full multi-sensor prototype, including system integration, and extensive testing. Key Phase II research objectives are: Design and Development of the CAA prototype, Development of video analysis methods, Design and development of processing and analysis methods, and Validation experiments.
