4D Scanning Technologies and Applications in Human Factors
SessionDemonstrations 1
DescriptionRecent developments in four-dimensional (4D) body scanning technologies are revolutionizing digital human models (DHM) by enabling the dynamic and high-resolution capture of body shape deformation during motion. This demonstration explores how 4D scans can be leveraged to extract anthropometric and biomechanical metrics critical to human modeling and interaction analysis. Utilizing a photogrammetry system capable of capturing 3D body shapes at up to 178 frames per second within a controlled environment, this technology enables large-scale, high-throughput data acquisition. An integrated computational framework facilitates the automated processing of this data, producing temporally consistent body mesh sequences with standardized topologies and anatomical correspondences across frames and subjects. In effect, the system functions as a high-density, markerless motion capture tool. The potential of this approach is illustrated through three live case studies: gait biomechanics—analyzing joint mechanics using synchronized 4D and force plate data; dynamic anthropometry—extracting ergonomic measurements for product design; and virtual ergonomics—integrating rigged body models into digital simulation environments such as Blender and Ramsis. These applications highlight the profound impact of 4D scanning in advancing human factors research, offering more accurate, data-driven insights into biomechanics, ergonomic design, and human–object interaction.
