Introduction
My name is Marc Weitz and I am currently doing my PhD in Medical Informatics at the university of Tromsø. I am doing research on sensor-based measurement of physical activity where I focus mostly on ActiGraph devices and extending the methodology to make use of their collected raw data.

Data
16 participants wore an Actigraph w-GT3X on their right hip together with two consumer-based wearables, a Polar Vantage (Polar Electro Oy, Kempele, Finland) watch and an Oura (Oura Health Oy, Oulo, Finland]) ring. This data, as summarized in this repository, has been used to validate an algorithm to detect time in bed. For more information, see the...
Article
Accelerometers are increasingly used to observe human behavior such as physical activity under free-living conditions. An important prerequisite to obtain reliable results is the correct calibration of the sensors. However, accurate calibration is often neglected, leading to potentially biased results. Here, we demonstrate and quantify the effect o...
