About ERL has developed tools that design seats for the global population. The tool is a computer program that uses a non-linear optimization algorithm to maximize vision and comfortable joint angles for the driver in a biomechanical model of the seat. Each driver in the model has a comfort score that is calculated from the optimized results and this score correlates with the subjective scores of real drivers at r=0.8. This tool is patented and has been used for 10 years in the auto industry in the US. It is available for use worldwide. For interested inquiries, please contact me.
