Ergonomics Ergonomic

Ergonomics (or human factors) is the scientific

discipline concerned with the understanding

of interactions among humans and other

elements of a system, in order to optimize

human well-being and overall system

performance.

Divisions of Ergonomics

Ergonomics promotes a holistic approach in

which considerations ofphysical, cognitive,social, organizational, environmental and

other relevant factors are taken into account.



13/23

Divisions of Ergonomics

Physical

Physical ergonomics is concerned with human

anatomical, anthropometric, physiological

and biomechanical 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.)



14/23

Cognitive

Cognitive ergonomics is concerned withmental processes, such as perception,memory, reasoning, and motor response, asthey affect interactions among humans and

other elements of a system. (Relevant topicsinclude mental workload, decision-making,skilled performance, human-computerinteraction, human reliability, work stress andtraining as these may relate to human-systemdesign.)

MusculoSkeletal Disorder




20/23

A musculoskeletal disorder is a condition

where a part of musculoskeletal system is

injured overtime.

The disorder occurs when the body part is

called on to work harder, stretch farther,

impact more directly or otherwise functionat a greater level then it is prepared for.

The immediate impact may be minute, but

when it occurs repeatedly the constanttrauma cause damage.
