FRISCH, G. D., and L. A. D'AUI.ERIO. Bioman—An improved occupant-crew station compliance modeling system. Aviat. Space Environ. Med. 51 (2): 160-167, 1980. The need to visualize and interpret liuman body movement data from experiments and simulations lias led to the development of a computerized, three-dimensional representation of the human body and crew station. While conventional charts and graphs can be used to follovf movements of individual body parts, it has been our experience that only by observing the entire movement of the various body segments can experimental results be Integrated with simulation studies. Such a process requires that program output be used to animate a realistically formed and jointed human body model incorporated within an existing or projected crew station. Animations are essential whenever the volume of data collected or generated is too great to assimilate piecemeal, or when the complexity of the motion under study leads to visualization difficulties in a two-dimensional graph. Dissatisfaction with existing body models and stick figure displays led to the development of a new human and crew station model for the computer with distinct advantages in display realism, movement definition, collision or interaction detection, and cost-effectiveness in a real-time animation play-back environment. Development of this program was meant to provide an improved method for evaluating the physical compatibility of crew members with crew stations under all types of G environments.
