Virtual Prototyping with Real-Time Rendering for Kansei Engineering of Leather Grain Patterns on Car Dashboard Panels

抄録

Along with recent developments of industrial finishing of plastics, simulating surfaces is much desired in industries. This research attempts to build a virtual prototyping system for surface finishing. Simulating surfaces will accelerate to Kansei-oriented product development without large cost of making real prototypes. Since the developed system renders bumpy and glossy surfaces in real-time, evaluator can accurately examine surfaces. As an application of the system, leather grain patterns of car dashboard were simulated. At first, surface details of car dashboards were measured with a laser 3D range finder device. Then, Kansei evaluation was done with 30 virtual prototypes those have variations on cars, intensity of roughness and with or without gloss. The evaluation result was analyzed with PCA and 3-factor ANOVA. Expression capacity of the system was validated with ANOVA results, those show significant effects of virtual prototype parameters on Kansei evaluation.
