Construction of car instrument panel design support system using eye model coupled with musculoskeletal model

Abstract

In recent years, the number of switches installed in automobiles has increased, which has contributed to prolonging the design of the driving operation space. The purpose of this study is to evaluate the visibility of instrument panels of automobiles using an eye-body-coordination movement model that minimizes physical load and eye load and maximizes the visibility rate. The human body movement is calculated by a musculoskeletal model, and the visibility evaluation system is realized by a visual geometric model using 3-dimensional computer graphic software. In order to evaluate the validity of this system, a verification experiment compared with the simulation output. As a result, eye-body-coordination movement were confirmed under all conditions. The correlation between the visibility score of simulation and the sensory test was strong, and the validity of the evaluation index was confirmed. This system is assumed to be used in actual design, and the user can execute a simulation without knowing the details of the system.
