The category strategy of human body size with age intervals

Sizing category strategy play an important role in the anthropometric measurement, it will affect the application of the different fields, including garment, ergonomic product, interior design, working space and nutritional status of people.Through the three-dimensional (3D) body scan process, this research collect 8463 digital human models from the Chang Gung Memorial Hospital. It categories the human body size by two body indexes and four age intervals. The result shows that Body Mass Index (BMI) could be the better sizing strategy to category the human body size. And the "age-10age" interval has the minimum Mean Absolute Difference (MAD) with the 22 body dimensions which compare with the 56 standard human models than the three age interval in both genders. The index "BMI" and "age-10" interval could be the better strategy to category the human body size. The standard human models could be the better template to analyze the digital human model; it will provide a quick and effective method to collect the body dimensions to the different applications.
