A particular focus of the USC REACH Lab is the development, testing, and application of real-time data capture methodologies to better understand the effects of environmental, social, and psychological factors on eating and physical activity.
Our projects use remote sensing and communication technologies such as smartphones, accelerometers, and GPS to deliver real-time electronic surveys (Ecological Momentary Assessment [EMA]), measure physical activity and eating, and monitor geographic location to better understand causes and correlates of health behavior.
We are also running several projects that integrate Bluetooth signals from external sensors such as asthma inhalers, air pollution monitors, and ultraviolet sensors to trigger smartphone-based EMA Surveys.
