There is a great demand for data on the mobility and strength capability of
the human body in many areas, such as ergonomics, medical engineering, bio
mechanical engineering, computer graphics (CG) and virtual reality (VR). Th
is paper proposes a new method that enables the calculation of the maximal
force exertable and acceleration performable by a human body during arbitra
ry motion. A musculoskeletal model of the legs is used for the calculation.
Using our algorithm, it is possible to evaluate whether a given posture or
motion is a feasible one. A fool to visualize the calculated maximal feasi
bility of each posture is developed. The obtained results can be used as cr
iteria of manipulability or strength capability of the human body, importan
t in ergonomics and human animation. Since our model is muscle-based, it is
possible to simulate and visualize biomechanical effects such as fatigue a
nd muscle training. The solution is based on linens programming and the res
ults can be obtained in veal time. Copyright (C) 1999 John Wiley & Sons, Lt
