Abstract:

This paper first reviews the current state of the art with respect to emerging person-based passive monitoring techniques applicable to examining human activity (especially physical activity) in built environments. Assessment of the literature suggests that three-component system is most viable for this purpose, involving use of GPS and accelerometer tracking, along with limited self-reporting. An important key to such a system is obtaining the data in a timely fashion so that it can be processed and displayed back to subjects for confirmation, updating, and addition of supplemental attributes. This paper demonstrates such a system, utilizing a RIM BlackBerry smartphone to obtain data wirelessly, automated activity detection algorithm, and web-based graphical interface for interaction with subjects. This includes a prompted recall diary that displays automatically detected activities and travel, and allows subjects to modify and add attributes via mouse clicks, fly-out menus, interactive maps, and check box lists. Example data taken from a study of 40 diabetic patients is used to illustrate and test the system. Data capture rates, technical issues, and respondent issues are examined in detail. Results suggest that wireless data transfer greatly improves the ability to monitor incoming data and maximize data capture, allowed immediately interaction with subjects, and allowed utilization of large spatial databases for automated activity-detection purposes. Future applications of such a system for physical activity promotion and patient care are discussed.
