Human dummy system for evaluating comfort of seat

摘要

A human dummy system for evaluating the comfort of a seat comfort includes sensor units and a data processing unit. The sensor units are attached to the relevant joints of a human dummy, and detect the angles of the relevant joints. The data processing unit calculates information about relative locations of adjacent joints on the basis of the information about the angles of the relevant joints, and calculates the absolute location of a specific joint through coordinate system transformation between the information about relative locations and the joints of the human dummy.
