ABSTRACT
As with other professions, one way to conceptualize ergonomics is by its unique technology. From my perspective, the unique technology of ergonomics is human-system interface technology. In this context, a system can be as simple as one person using a hand tool or as complex as a large multinational industrial organization. The science of ergonomics is concerned with developing knowledge about human performance capabilities, limitations and other characteristics as they relate to the design of the interfaces between people and other system components. The practice of ergonomics is concerned with the application of this human-system interface technology to the design or modification of systems to enhance system effectiveness, including productivity, safety, and the quality of work life.
