Ergonomics/comparison between two areas confusion


hello dear

I m asking about confusion ;

the difference between 1-  human centered engineering design  ans 2- human factor and engineering psychology ?

from where concept also applications

also does the both majors required using some tools like auto desk programs like autocad and other

I have a bachelor degree on communication system engineering , so what can I do to pursue a career on the both major mentioned above noticed that I want to merge my engineering studies theories with psychology and anthropology science ??????????????

please advise

Hello Ahmed,
At the risk of oversimplifying to two fields, based on what you said was your interests, this is how I would look at it:

Human centered engineering design looks at the task needing to be done, the environment in which those tasks must occur, and the physical limitations of the human machine in order to create or design tools, programs, or devices.  Think of this of designing equipment based on human abilities.

Human factor and engineering psychology focuses on the study of how people interact with machines, tools, programs in order to determine best guidelines for behavior change or reactions. Think of this as doing research (and application) regarding how humans use or perceive things.

For more information:,

I look to my other experts online to answer the rest of Ahmed's question about careers.

I can answer questions regarding office, healthcare, and industrial ergonomics as well as general health and safety issues. I specialize in macro-ergonomics which deals with both individual issues (such as injuries and prevention) as well as corporate/organizational prevention plans. This includes working with companies that are interested in creating company-wide safety programs, health programs, and intervention strategies. My background is in occupational therapy and I am able to answer questions regarding specific medical injuries and workers compensation. This also makes me uniquely qualified to speak on the aging workforce and modifications specific to that population. I cannot answer questions regarding OSHA regulations and legal issues. While I know some things about manufacturing, I am not an engineer and tend to refer some of those questions to others.


My company, Worksite Health & Safety Consultants, an ergonomic and occupational health consultation firm has just turned eight years old. We are located in the Washington metro area. As owner I travel around the world speaking on ergonomics, aging in the workplace, and occupational health. I have consulted in the field of occupational health and ergonomics for the last twelve years. Additionally, I am an Occupational Therapist and have specialized in the treatment of work injuries/work-related musculoskeletal disorders and modifications for return to work post-injury for the last fourteen years.
