New Advances in Volitional Human Mobility Simulation
The use of computerized kinematic models of the human body has greatly increased in the last few years. This paper describes the results of research conducted to quantify the configurations of the human body most often chosen by people when reaching with one hand about their immediate environment. In performing this research basic size and volitional mobility data of the human torso were developed. These data have been used in constructing a computerized kinematic model, the output of which is a linkage representation of the body which is either displayed on a CRT or drawn by a computer driven X−Y plotter.
It is proposed that with this type of model a designer of crash dummies can begin to develop future dummies that better represent the size and mobility of various body segments, particularly the torso. In addition, the effects of various gross anthropometric variations (e.g., body weight and stature) on volitional body configurations and specific segment dimensions can be predicted for occupant packaging design evaluations. Also, the “most preferred” configurations of the body for given right hand positions becomes useful data for the design of restraint systems which not only then could minimize injury potential but maximize volitional function, thereby adding to their social acceptance and the resulting user safety.
