Research Topics

Analysis and utilization of 3D human body forms

The purpose is to develop techniques for utilizing the infomration on 3D human body forms for designing industiral products for which the morphological fit to the human body is essential. The 3D surface form data of human body is normalized based on anatomical correspondence (homology). Such homologous models are utilized for analyzing the variations in 3D body forms as well as calculating virtual forms representing the distribution of 3D forms for a population. The differences between 2 homologous models are represented by a transformation function that deforms the original form into the target form. The transformation function is utilized for designing 3D product forms.

Human morphological variations

Japan has experienced a very rapid secular change in last 100 years. Due to the secular change, variations in Japanese body size and shape is exceptionally large at present. Since industrial products must cover the very large variation, it is important to know the range and the cause of variations. For example, younger generations and older generations are different in body size and form. Is it because older generation has changed due to the aging process? Or, is it because older generations are different from younger generation due to the secular change? I am interested in factors that cause systematic differences between population groups such as age, gender, size, and race. I am also interested in the changes in forms due to the movement.
