Ergonomics is the science of designing products in accordance with the way humans think, see, and behave. Proper design will dramatically reduce human error, fatigue, discomfort, and stress, and have a profound positive impact on overall end-user performance.
Ergonomics reduce learning curves and limit the amount of customer education required. Good ergonomics directly contribute to the success of the product in terms of customer satisfaction, market share, and profitability. The research is well worth the effort.
