Two dimensional computer models of the average man, small man, and large man were developed to represent the geometry and movements of operator in seated postures on the basis of analyzing the earth moving machinery's characteristics. The human H point was taken as datum point and the posture angles were linked to easy operation, open vision and comfortable seat. The H point region was obtained by means of CAD technique. The region can be used for design and/or check purposes.
