Occupant Posture and Position Modeling

UMTRI researchers routinely develop customized data-processing and analysis programs using software such as Mathematica, Visual Basic, SQL, and Labview. For example, researchers recently developed a computer program to provide biomechanical researchers and modelers a graphical interface to MS Access for selecting and viewing quantitative data on radiographic-based cervical-spine geometry in the automotive posture based on stature, age, and gender. Researchers routinely use Mathematica to develop customized programs to analyze anthropometry and posture data, and to develop models for posture prediction, seatbelt fit, and other aspects of driver accommodation. Results from these models are used in conjunction with Jack and RAMSIS human models to provide industry human factors and safety engineers with updated design tools for vehicle interior and restraint design to improve driver protection and accommodation.
