Digital human modeling is next step in ergonomic studies and dynamic human simulations. SantosHuman has developed SANTOS, which is a biomechanical computer-based human that predicts things such as static posture, dynamic motion, joint strength, and fatigue. SANTOS aids in the study and evaluation of environmental impacts on the human body. Their software is superior to current software in terms of degrees of motion, appearance, and predictive capabilities. SANTOS was developed using the results from over 16 years of simulations, 14 years of multi-body dynamics, and 10 years of robotics to produce the most realistic simulation program available.
