Structural analysis of steering wheel grip comfort by semantic differential method

Kansei quality varies with individual. Therefore, when building structural model of Kansei quality, it is very important to identify some essential structures by analyzing individual differences. In this work, semantic differential method is conducted in order to improve steering wheel grip comfort. Assuming a hierarchy structural model of the steering wheel grip comfort, the individual differences are analyzed using principal component analysis and then some hierarchy structural models are built using graphical modeling. As a result, two remarkable different structures are built. Some guidelines for developing steering wheel production can be shown by comparing the different structures.
