Ergonomics is the study of human abilities and characteristics which affect the design of equipment, systems, and jobs. The terms ergonomics and human factors can be used interchangeably.
The name Ergonomics was derived from the Greek words: Ergon/ergos - work; Nomikos/nomos - natural laws - control and orderly assignment.
I recommend that anyone involve in the design and planning of buildings / structures / equipment interfacing with people should obtain a copy of the reference handbook as linked on this page . "Metric Handbook Planning and Design Data"
