Human Activity State Detection and Monitoring Systems (HASDMSs), involves "behavior" and not "performance" . These represent important elements of the more broad picture in which we are interested. We can infer minimum levels of capacity from knowledge of behavior; i.e., we can know that an individual possesses "at least" a certain amount of performance resource "x" if we document that they are using that much. HASDMSs are based on the recognition that although human activities may be quite dynamic, in communicating about them to each other we simply use a single "ing" word or phrase (e.g., "walking", "standing", "sitting", stair "climbing", etc.). We view these human "activity states".
