Abstract
An integrated system of mobility notation and standard techniques for measurement of spacesuit mobility is described. New terminology is proposed to describe human body movements for engineering workspace analysis and suit mobility specifications. Vector and link concepts are combined in a simplified model of man to describe body positions in terms of orientation of limbs with respect to a tri-planar angular coordinate system conceived as attached to the pelvic region. Numerical coding of the body links and joints is described. The notation system may be used as a basis for mathematical modeling for computer analysis of vehicle workspace geometry and control locations. The system is independent of gravitational reference semantic implications and sufficiently general for a wide range of complexity in kinesiological, medical, and human engineering applications.
