## AI overview

Google researchers report a large-scale validation study showing that consumer smartwatches can accurately estimate comprehensive spatio-temporal gait metrics, including walking speed, step length, and double support time. They describe a multi-output deep learning model using a temporal convolutional network and smartwatch inertial sensor data, with performance comparable to smartphone-based methods.
