The purpose of the study is to extract typical body shapes of Koreans based on their three-dimensional anthropometric data measured through 5th national anthropometric survey known as SizeKorea and to examine the suitability of the 3D human shape data for vehicle interior packaging. 36 three-dimensional anthropometric variables that are related to the interior design of vehicles were considered for the generation of typical body shapes. Major factors were extracted by the factor analysis and factor scores were calculated for all subjects with respect to age groups and gender. Typical or standard drivers of Korean, who must be tested for the suitability of design during the design process, were selected by the minimum deviation criteria for the major factor scores with respect to 5th, 50th, and 95th percentiles, respectively. Since human models such as HUMAN are frequently used in vehicle design, it is of great importance to make sure that its dimensions conform to those of real Korean drivers. There exist critical differences between selected anthropometric data of Korean and modeling data provided by HUMAN. This suggests that comparative research about these differences need to be undertaken and any modeling data provided by computer human models should not be applied to the ergonomic evaluation for the vehicle design without a careful review. It is also expected that anthropometric data of a set of typical drivers extracted from the study help designers conduct package layouts and improve the suitability of ergonomic evaluation for Korean customers.
