What are the three categories of ergonomics?

The three categories of ergonomics are physical, cognitive, and organizational ergonomics. Physical ergonomics focuses on the human body's responses to physical demands and includes factors like posture, repetitive movements, and workstation design. Cognitive ergonomics deals with mental processes and human-computer interaction, emphasizing how people perceive, remember, and make decisions. Organizational ergonomics involves optimizing sociotechnical systems, including communication, teamwork, and organizational culture, to enhance overall productivity and well-being.
