Construction of parametric model of operator and workstation

The purpose of development of a parametric model and the construction and formulation of the parametric model are described. To validate the parametric model, the distribution of the difference between the preferred and theoretical seat height settings of a number of office workers was evaluated from the standpoint of the static posture that does not change with time. The results of precise measurements made for an engineering workstation and an operator were also evaluated. Finally, the theoretical seat height settings with dynamic posture were evaluated. The validity of the parametric model was verified under the experimental conditions.
