Our 3D anthropometry team, including my colleages Dr. Daniel Park andDr. Monica Jones, have published the first whole-body parametric human body model for supported seated postures. This is also the first published body shape model for seated postures to include a rigorously derived effect of age. Since nearly all design applications in seating involve backrest support, this closes a large gap in the literature. This stream of research goes back 20 years, to early modeling using the CAESAR dataset. Our first model for seat and chair design was published in 2008, but that model was limited to the torso area. The recently published model was developed about 2016, but it took us a few years to get around to reporting it in the journal literature. Meanwhile, our group has made extensive use of seated body shape modeling in parametric human body modeling. A related model has been available at HumanShape.org for a few years. An additional publication is in the works that demonstrates parametric posture change driven by validated posture-prediction models.
