typically efficiency is part of the consideration of ergonomics.
Quote: «Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.»
Note the last few words: “... and overall system performance”.
