jmThe ability to measure physical activity through wrist-worn devices provides an opportunity for cardiovascular medicine. However, the accuracy of commercial devices is largely unknown. The aim of this work is to assess the accuracy of seven commercially available wrist-worn devices in estimating heart rate (HR) and energy expenditure (EE) and to propose a wearable sensor evaluation framework. We evaluated the Apple Watch, Basis Peak, Fitbit Surge, Microsoft Band, Mio Alpha 2, PulseOn, and Samsung Gear S2.
tl;dr: wrist-based calorie counters were inaccurate by up to 93% in tests.]]>fitbit microsoft mio pulseon samsung-gear apple apple-watch basis gadgets health heart-rate calorie-countershttps://pinboard.in/https://pinboard.in/u:jm/b:529e3807f428/
