How is ergonomics defined?

Ergonomics is primarily defined as the study of how people interact with products, systems, and environments, with the goal of designing tools and workplaces that fit the users' needs and capabilities. This understanding helps improve efficiency, safety, and comfort in various settings. By focusing on user interaction, ergonomics seeks to enhance performance while reducing the risk of injury and discomfort linked to repetitive motions or poor posture.

In contrast, the other options may touch on aspects related to design, such as aesthetics or developing new products, but do not capture the essence of ergonomics. While product aesthetics is important in design, it does not address the functional relationship between users and their environments. Similarly, the development of new electronic products and making products environmentally friendly are distinct fields that do not encompass the user-centered focus that defines ergonomics. Therefore, option B is the most accurate and comprehensive definition of ergonomics.
