,profession that applies theory, principles, data, and methods to design in
order to optimize human well-being and overall system performance
Physical Ergonomics - ✔✔concerned with human anatomical,
anthropometric, physiological and biomedical characteristics as they relate
to physical activity.
-Relevant topics include working postures, materials handling, repetitive
movements, work-related musculoskeletal disorders, workplace layout,
safety and health
Cognitive Ergonomics - ✔✔concerned with mental processes such as
perception, memory, reasoning and motor response, as they affect
interactions among human and other elements of the system. Relevant
topics include mental workload, decision-making, skilled performance,
human-computer interaction, human reliability, work stress and training as
these may relate to human-system design.
