Purpose Actigraphy-based sleep detection algorithms were mostly validated using nighttime
sleep, and their performance in detecting daytime sleep is unclear. We evaluated and …

Goal and aims Commonly used actigraphy algorithms are designed to operate within a
known in-bed interval. However, in free-living scenarios this interval is often unknown. We …
