Using a Spoken Diary and Heart Rate Monitor in Modeling Human Exposure to Airborne Pollutants for EPA’S Consolidated Human Activity Database
In this paper, we describe technology used to collect fine-grained data of individual daily human activity including information related to time, exertion, specific activity, and location. This data uses the Consolidated Human Activity Database developed by the EPA’s National Exposure Research Laboratory and is used to build models of human exposure to airborne pollutants. This paper will look specifically at subject compliance and quality in a small pilot study and the automatic classification of activity and location based on a spoken language diary collected from a digital recorder.
