Mobile and Bluetooth Wireless Technologies in Longitudinal Surveys of Human Exposure-Related Behavior
Zhang, Y. (2006, May). Mobile and Bluetooth Wireless Technologies in Longitudinal Surveys of Human Exposure-Related Behavior. Presented at International Field Directors and Technologies Conference, Montréal, Canada.
This presentation provides an overview of technologies under development and initial experience in collecting longitudinal data on human exposure-related activities supported by EPA STAR Grant RD-83154101-0, the purpose of which is to develop and evaluate methods that can be readily adapted for use by other longitudinal studies of human exposure-related behavior. The challenge is to collect a broad range of survey, physical, and physiological data, maximize accuracy and completeness, and minimize participant burden. Centered on Pocket PC mobile device, the system integrates forms-based diaries and questionnaires with a collection of wireless peripheral devices for monitoring physical and physiological data. Heart rate, ECG, indoor location, KeyFOB-activated product-use events, GPS, and other data are collected via a set of miniature wearable devices linked via Bluetooth wireless to the Pocket PC. Voice diaries are taken via Bluetooth linked headsets. To help ensure data quality, artificial intelligence methods are being devised to prompt for missing data and check consistency across collection subsystems. A pilot test is being conducted in 40 homes to compare the functional performance for various devices and modes of data collection. Preliminary results from the pilot test will be presented.
