    Abstract: © 2002 Asian Journal of Ergonomics - This study established a 3-D craniofacial anthropometric database and applied it to the design respiratory masks. A 3-D photo-grating measuring system, which scans more than 100,000 3-D surface points in 94 seconds, was used to measure craniofaces. The database consisted of 1213 subjects, randomly selected from the Taiwanese worker population, but adjusted for gender and age group distribution. This database was used to extract 39 1-D measurements and select three 3-D head models for the design of respiratory masks. These 1-D measurements were calculated from a set of 24 anatomic landmarks, of which 16 were identified automatically and 8 were identified manually. These three 3-D head models are intended to represent the small, medium and large size groups, which fit best the whole population. The 3-D had models were processed by sizing and selection procedures. The sizing procedure was to group the data into three size groups by optimizing the dispersion of the face length and face breadth against allowable design tolerance. The selection procedure was to select a "typical model" within each size group using the form-difference analysis technique. The typical model had the smallest form-difference value within the group. Finally, these three 3-D head models were made by a computerized numerical control machine(CNC) and used for the design of respiratory masks.
