3D scan images have been successfully applied in ergonomic product design. Features of human body parts (e.g., landmarks, measurements, curvatures, surfaces, volumes) extracted from 3D body scan images can be used to analyze variations of the size and shape of human bodies. The information of size and shape variations can be applied in product design to support technical ideas regarding accommodation, tolerance, and adjustability. This study is aimed to briefly introduce a few analysis methods of body shape variation using 3D facial scan images of Dutch children in order to acquire useful features for the design of a children’s facial mask.
