The Oregon Center for Aging and Technology (ORCATECH) seeks to facilitate successful aging and reduce the cost of healthcare by establishing the evidence base for technologies supporting aging-in-place research and care. This is done through pilot studies evaluating the role of the technologies, as well as large longitudinal studies in which sensors are placed in the homes of community-dwelling elders to monitor daily patterns of activity, walking speeds, medication adherence, and other behaviors. These sensors collect continuous data that reflect normal variability in behaviors as well as trends that may indicate problematic changes in cognition or mobility. Because data are collected continuously, trends can be identified long before they would become apparent during a typical clinic visit. However, the use of low-cost sensors means that the data are inherently noisy, and extraction of meaningful behavioral data is not trivial. In this talk I will give an overview of the challenges inherent in this approach, and will describe some of the analyses that are proving fruitful.

Biographical Information

Dr. Hayes received her MS in Electrical Engineering at the University of Toronto and her PhD in Behavioral Neuroscience from the University of Pittsburgh. She was worked in both industry and academia, on projects ranging from creating tools for remote management of distributed systems to delivering teledermatology care to rural Oregon. Dr. Hayes' current research interests include the use of technology to deliver health care in the home, with the goal of changing the current paradigm of clinic-centered healthcare to a model that is less costly, more effective, and allows an individual to participate more fully in their own health care. This research entails the use of low-cost unobtrusive sensors in the home for collecting behavioral data related to acute and chronic motor and cognitive changes, and meaningful analysis of these data to assist and inform the patient. Dr. Hayes is Assistant Professor and Associate Department Head in the Division of Biomedical Engineering at Oregon Health and Science University’s School of Medicine.
