The Science of Ergonomics primarily focuses on optimizing interactions between humans and various elements of their environment to enhance well-being and overall performance. This encompasses studying human abilities and limitations, designing tasks and systems that fit those characteristics, and ensuring safety and efficiency in the workplace.

Anthropometry, which is the study of human body measurements, is essential in ergonomics as it helps in designing tools, workspaces, and equipment that accommodate the physical dimensions of users. Automation refers to the use of technology to perform tasks, which relates to ergonomics as it can affect the way humans interact with systems and tools, optimizing performance and reducing strain.

Autokinesis is a phenomenon that occurs when stationary lights appear to move, which is relevant in certain contexts of visual ergonomic studies. Understanding visual perception is crucial in ergonomics to assess how various lighting conditions affect worker safety and performance.

In contrast, autotrophic does not relate to ergonomics. This term pertains to organisms that can produce their own food from inorganic substances, a concept primarily concerned with biology and ecology rather than the human-centered focus of ergonomics. Therefore, autotrophic is the option that does not fit within the scope of the Science of Ergonomics.
