ABSTRACT
Ergonomics concerns the application of the scientific information, which is derived from the processing of collected data, to improve the work systems or products for human use. For research of ergonomics, it is critical how effectively the collected data are processed. The data for ergonomics may come from human operators, work environment and their interaction, and have various types, such as anthropometric (e.g. height and weight of human operators), physiological (e.g. heart beat rate), and psychological (e.g. cognitive ability or user satisfaction) data. Ergonomic data have been accumulated via a variety of experiments and surveys, and various research results of ergonomics have led to many guidelines for work environment, systems, or products. When appropriate analytic methods are selected, new patterns of ergonomic data can be found, and also a generalized conclusion can be drawn via combining accumulated results of ergonomics research.
