Ergonomics is the study of human interaction with a system and how the human body, movements, and cognitive abilities interact with the system. In injury causation investigation and analysis this can involve studying how a person should safely interact with an environment or system.
The International Ergonomics Association defines ergonomics in three categories:
- Physical ergonomics is concerned with human anatomical, anthropometric, physiological and biomechanical characteristics as they relate to physical activity.
- Cognitive ergonomics is concerned with mental processes, such as perception, memory, reasoning, and motor response, as they affect interactions among humans and other elements of a system.
- Organizational ergonomics is concerned with the optimization of sociotechnical systems, including their organizational structures, policies, and processes.
Relevent topics of ergonomics include:
- Working postures and repetitive movements
- Work-related musculoskeletal disorders
- Workplace layout, safety and health
- Human-computer interaction
- Human-system design
