"How do video and accelerometer data together improve activity tracking in children?"
In this second part of the episode, Dr. Olli Tikkanen and Dr. Ying Gao discuss her innovative study combining accelerometer and video observation data to improve activity classification in children. Dr. Gao explains how she adapted wearable cameras and accelerometers, including Fibion devices, to measure activity across various body locations such as the back, chest, and wrist. This setup allowed her team to validate physical activity and sedentary behavior in school-aged children, accurately differentiating between sitting, standing, and moving.

Dr. Gao also describes the meticulous video coding process, which involved tracking leg movements without capturing faces to maintain privacy. Her research highlights the challenges and benefits of integrating video and accelerometry to obtain reliable data on children’s movement, especially in free-living environments. This episode offers insights for researchers interested in advanced methods for studying physical activity and sedentary behavior in children.
