 An Efficient Approach for Tracking Physical Activity with Wearable Health-Monitoring Devices | NC State News | NC State University
Researchers from North Carolina State University have developed an energy-efficient technique for accurately tracking a user’s physical activity based on data from wearable devices.One goal for wearable health technologies is to identify and track physical activity by the wearer. However, accomplishing this goal requires a trade-off between accuracy and the power needed for data analysis and storage, which is a challenge, given the limited power available for wearable devices.“Tracking physical activity is important because it is a key component for placing other health data in context,” says Edgar Lobaton, an assistant professor of electrical and computer engineering at NC State and senior author of a paper on the new work. “For example, a spike in heart rate is normal when exercising, but can be an indicator of health problems in other circumstances.”
