Abstract

Recently, many methodologies for industrial designing considering usability have been widely studied. For example, Banzai Factory Inc. has developed a tailor-made cup with curves just fitted to each person’s grip form, which is called “Waga-Hai”. In the manufacturing process of “Waga-Hai”, the person’s grip form is converted to 3D polygon data. Thus we believe that these data have some important information to make mathematical models for determining a comfortable grip form. In this paper, we developed the method using 3D image processing techniques to extract some features, i.e. positions/directions of fingers and relationships among them, from the 3D polygon data. The obtained results showed that gripping trends could be categorized into 5 classes and the obtained features would be one effective for the mathematical models.
