Outline of Final Research Achievements

This research developed the novel digital human model and its computational algorithm that would be applied to the human motion analysis and somatosensory information (e.g. muscle activity) estimation for medical care, rehabilitation and sports science. I built the volumetric skin-musculoskeletal model that represents the human anatomical geometry based on BodyParts3D that is available under Creative Commons license. The volume deformations of skin and muscle were realized by applying Skeletal Subspace Deformation that is used for the skinning of character animation in the computer graphics field. My model and algorithm improved the accuracy of the muscle moment arm estimation (decreased its maximum error from 45% to 14%) by computing the muscle pathway from the deformation of the volume muscle model. This model and algorithm would contribute to the improvement of somatosensory information estimation.
