"How do event markers enhance accelerometer data for research?"

In this episode of the Physical Activity Researcher Podcast, Dr. Olli Tikkanen explains the importance of event markers in accelerometer-based research. He introduces the event marker feature in the Fibion G2, a simple button that participants can press to timestamp specific activities, adding real-world context to raw data. This feature enhances data accuracy and clarity by linking accelerometer signals to specific events such as sleep transitions, exercise, or work hours, making it easier to analyze participant behavior.

Dr. Tikkanen shares practical applications of event markers, including distinguishing between sleep and wake times, segmenting occupational and leisure activity, and validating self-reported data. He also highlights how this feature improves adherence in daily life settings by eliminating the need for smartphone apps. This episode is ideal for researchers looking to enhance data quality and automate analysis using context-rich data.
