摘要：SummaryMotion tracking provides unique insights into motor, cognitive, and social development by capturing subtle variations into how movements are planned and controlled. Here, we present a low-cost, wearable movement measurement platform, KiD, specifically designed for tracking the movements of infants and children in a variety of natural settings. KiD consists of a small, lightweight sensor containing a nine-axis inertial measurement unit plus an integrated processor for computing rotations. Measurements of three-dimensional acceleration using KiD compare well with those of current state-of-the-art optical motion capture systems. As a proof of concept, we demonstrate successful classification of different types of sinusoidal right arm movements using KiD.Graphical abstractDisplay OmittedHighlights•We developed a wearable platform (KiD) designed for tracking movements of children•We establish the potential of KiD as stand-alone movement measurement platform•We demonstrate successful classification of different types of movements using KiD•Accelerations collected using KiD compare well with those of optical MoCap systemsBiological sciences; Neuroscience; Behavioral neuroscience; Techniques in neuroscience
