🔍 What is Wearable Landscape?
An open-science project aiming to foster collaboration in the field of #Wearables. We want to bring experts together, to ultimately advance the validation and application in wearables that track 24-hour physical behavior (sleep, sedentary time, activity) #OpenScience

📢 New paper out!
We calibrated and evaluated MET models for walking and jogging using the Move 4 wearable on the ankle and thigh — with strong agreement vs indirect calorimetry (gold-standard).
Great progress for high-resolution energy-expenditure estimation using Move 4 accelerometers 👏

💭How to be #transparent and #fair in large collaborative review processes regarding authorship?
We adressed this in our present review (>200 included studies and 24 scientists involved) and developed a weighted scoring system based on the time required for different tasks to fairly credit workloads.

📊 New review on 24-h movement behavior assessment using #accelerometers!
102 studies across all ages show huge variation in protocols — from wear-time rules and epoch lengths to cut-points and devices.

🗝️ Harmonization is key to make results more comparable across studies and countries.

#Wearables step-count validation ✅⌚

In a study of 21 wearables on the treadmill, authors found significant effects of walking speed, wear position, and age on accuravy. Many wearables track steps reasonably well, independent from being a commercial or research-grade device.

🎯 Testing the accuracy of 21 #algorithms for estimating sedentary time with wrist-worn #wearables revealed only 5 (24%) were within 10% of the gold standard. Two machine learning 🤖 and three posture-based cut-points performed best.
Great contribution to identify precise algorithms for wearable data!

Why is #validation essential for wearable-use in research?

Not all #wearables are created equal. Their validity depends on context such as target behavior, sensor placement, and assessed population. Therefore, validation studies are crucial to improve feedback and ensure measurment accuracy! 🎯
