Experiments and evaluation of body pressure distribution in automobile man-machine interface

According to the theory of human physiology, anatomy and biomechanics, the anatomical structure at buttocks and thigh area is analyzed to propose a general criterion on the comfortable body pressure distribution in man-machine interface. The experiments for body pressure distribution in driving environments and subjective evaluation are performed on a specially designed test stand. The experimental results from subjective assessment on four kinds of seat cushion indicate that the chair seat is an important factor affecting seating comfort, different chair seats are endowed with the corresponding seating comfort. The experimental results from objective assessment indicate that the presented criteria for the body pressure distribution in man-machine interface is sufficiently accurate to evaluate the seating comfort in man-machine interface. The distributed test system enables to survey and protract the body pressure distribution curve of different seat cushion effectively.
