Sensory evaluation using human subject is commonly utilized in designing the shape of a product when human perception such as gripping comfort is taken into consideration. However, since it is not possible to quantitatively evaluate it using physical parameters, there is a difficulty in finding the optimum shape based on engineering knowledge. In this study, a volunteer experiment was conducted against six test objects using a pressure distribution measurement system, a motion capture system and a sensory evaluation questionnaire. Contact pressure distribution, hand posture and gripping comfort score could be obtained from the experiment. Multiple regression analysis was then performed in order to determine the relationships between the gripping comfort and the contact surface pressure as well as the hand posture. In addition, the accuracy of the regression equations were evaluated by estimating the gripping comfort score from the contact surface pressure obtained from the experiment.
