Design equations for anthropometric product design are developed by considering the geometrical relationships of design dimensions and anthropometric dimensions. The present study applied the design structure matrix (DSM) method to the development of design equations for a computer workstation, and compared design values from the design equations with corresponding design values of ergonomic recommendations and existing products. The relationships between design dimensions (e.g., legroom and worktable) were analyzed by a DSM, and then the application order of design equations (e.g., seatpan, backrest, armrest, legroom, and worktable in descending order) was determined. Next, design equations were developed by analyzing the geometric relationships between computer workstation design dimensions and anthropometric dimensions. Finally, design values for a computer workstation were determined by considering a standard posture defined and representative human models (5th, 50th, 95th %ile). The design values calculated using the design equations were similar with those of ergonomic recommendations found in literature and two commercial products measured in the study; however, some design values (e.g., seatpan height) were different due to discrepancy in standard posture. The DSM method would be utilized to systematically analyze the relationships between design dimensions for anthropometric product design.

The present study developed an anthropometric design method accommodating physical human variabilities for user-centered product development. The proposed design method is based on the boundary zone method, a technique to generate a group of humanoids properly representing the body size diversity of thedesign target population. In addition, the anthropometric design method considers the variability of postures in the design process by incorporating the simulation of posture. The effectiveness of the proposed design method was evaluated in terms of multivariate accommodation percentage (MAP) by applying it to designing a computer workstation with 90% of accommodation percentage. The performance evaluation showed that the MAP (89%) of the computer workstation design produced by the proposed method was quite close to the designated accommodation percentage. The proposed design method can be of use to develop an effective anthropometric design for user-centered product development.

Although the entrance of house has been identified as a hotspot for older adults' fall accidents, there was not any lift chair to prevent older adults' accidents. In this study, a lift chair was developed to reduce fall accidents that can occur when older adults put on or take off their shoes in the entrance. In order to develop the product, we considered two aspects. Firstly, we considered older adults' anthropometric data to determine the design specification of the product. Also we considered the environmental characteristics of space using the product. In order to overcome the limited spatial freedom and use the entrance space effectively, we took a simplified and folding type for the product.

It is important to provide the opportunity and means to change body posture frequently during the work period. Maintaining a given posture, even if it appears comfortable in the beginning, becomes stressful as time goes on. In order to design most products some knowledge of the dimensions of the human body is required. Data concerning human body dimensions are referred to as anthropometric data. Anthropometric data are used to establish many product dimensions such as the heights of work surfaces, minimum size for access openings, spacing between controls, mounting angles for displays, distance between user and controls, and so forth. The usual procedure is to design to accommodate 90% of the population of anticipated product users. In sosme instances it is necessary to provide a method for adjusting because it allows users to alter the produst's dimensions to meet their individual needs. When the user makes the proper adjustments, the product will be easier to use (e.g., the seat and rearview mirror adjustment mechanisms on automobiles) or more comfortable (e.g., office chairs and stereo headphones).

A variety of research has been conducted on anthropometric dimensions and their applications to various products and space architecture, Also robust research has been conducted on various parts of human body and the possibility of applications. However, research on the specific dimensions regarding fingers and characteristics of hands have rarely been conducted in Korea. In addition, except for the NASA Anthropometric Source Book that suggests measures for specific purposes such as gloves and hand-operated device, almost no literature can be found on this topic, The primary objective of this study was thus to provide anthropometric dimensions of Korean hands and fingers and recommend appropriate product design solutions for human hands. Six hundred Korean male and female subjects aging from 11 to 93 were selected, Thirteen different hands and fingers were measured along with demographic data(e.g., age, stature, weight} to determine the relationships among these obtained data, The results of this study should be considered in ergonomic design for every hand-used products and hand-operated control devices.

Anthropometric data of the hand is one of the important issues for the product design related with hand and manual operation in terms of user-centered design. Direct measurement, which traditionally uses anthropometric measuring tool, has a few disadvantages in cumulation of measuring time, possible errors in raw data, doubtful reliability between inspectors. Newly introduced 3D scanning technology overcomes those disadvantages; however, another disadvantages, such as, hight cost and immovability, have been introduced. In this study, photogrammetric approach was introduced for the measurement of anthropometric data in hand. In order to minimize the possibility of error during direct and indirect measurement, a simulated object was used and effectiveness of photogrametric measurement was confirmed for the collection of anthropometric data in hand.

The objective of this study is to collect and analyze the anthropometric data for Korean adults. These data are intended to be used for the product design in industry. Sixty three college students participated in the measurement. One hundred twenty four lengths, thirty circumferences, four strengths, weight, and age data were collected. Descriptions and statistical analysis of the anthropo- metric data are summarized. The results were compared with foreign data available. It was found that forty weven body dimensions were closely correlated each other. It was also found that three dimensions, stature, eye height, and hand length, can be assessed by adding other body dimensions.

The purpose of this study is to categorize and analyze the body shape of obese Korean men that are needed for industrial design. Using the anthropometric data that were surveyed through the 5^th Size Korea project, this study was conducted in four steps mostly through the multivariate statistical analysis. In the first step, Broca, BMI, WHR indices are used to define obesity and select obese men from Korean adults and teens. After 34 human anthropometric variables are supposed to be related to obesity were extracted through an expect survey. In the second step, a factor analysis was executed for those human anthropometric variables. Through this analysis, we obtained the human body factors that are related to the representation of obesity. Then the third step, we used a cluster analysis from the result of the factor analysis. And ANOVA analysis was also conducted to obtain the critical obese human anthropometric variables. In the final step, we found the characteristics of the body types of obese men according to clusters and ages. The body types of obese men classified in the study are expected to be applied to product design for clothing, furniture, automobile packaging, etc.

As science advances in many fields, the task of accommodating all human beings with comfort and safety becomes increasingly complex. The anthropometric data are basis of product design, but most of the anthropometric data for Korean emphasize the anthropological, physiological and engineering points of views. Also due to the scarce of body dimensions needed in designing products, the industrial designers are cautious in applying these data to design products. The purpose of this study was to select and measure the body parts that are necessary for the industrial designers but are scarce in existing data, and to illustrate the human body with measures instead of tables for easy understanding and application to industrial product design. Three hundreds and eighteen males and 260 females of age from 18 to 60 participated for this study. Eighty-two dimensions in standing and seating posture were selected to measure. The front views, side views and some working postures for man and woman are illustrated with measures. This study could provide the most vital data to assist designers in creating products and environments that better accommodate human needs.

It is known that the human stature and its related dimensions generally increase until the late teens or early twenties, remain relatively constant throughout early adulthood, and decline from early-to-middle adulthood into old age. However, there is exception that the length of the human ears, which continue to grow throughout life. In this study, 600 Korean male and female subjects aging from 17 to 89 were selected. Four different points of external ears including Pinna length, ear connection point length, Concha length, and Lobule thickness were measured along with other relative subjects' demographic data(e.g., age, stature, weight) to determine the relationship among these obtained data. The results showed that the age, sex, and different ethnic populations were functions of ear dimensions similar to the human stature. For example, the Pinna length increases as the age increases(r= 0.689, p<0.00l). The primary objective of this study was thus to provide anthropometric dimensions of Korean ear for the product designers and recommend the appropriate product design solutions in relation to human ear. Based on the results of this study, it is suggested that the continuing growth of the human body parts should be considered in the application of anthropometric data to the design of the things especially for human use.
