What does Ergonomics primarily focus on?

Ergonomics primarily focuses on the arrangement of equipment and environments in a way that maximizes efficiency, safety, and comfort for users. This field studies how people interact with products and their surroundings, aiming to improve usability and reduce the risk of injury or discomfort. By examining human anatomy, physiology, and psychology, ergonomics helps design workspaces, tools, and devices that align with the physical and cognitive capabilities of users, thereby enhancing productivity and satisfaction.

The other options, while important in their own contexts, do not capture the essence of ergonomics. Aesthetic design is concerned with the visual appeal of products rather than their functional usability. Cost-effectiveness pertains to the economic aspect of production, focusing on the financial efficiency of manufacturing processes rather than user experience. Marketing strategies are designed to promote and sell products, which does not directly relate to how well those products meet the needs and comfort of their users through thoughtful design and arrangement.
