This document presents information about ergonomics. It defines ergonomics as the scientific discipline concerned with understanding interactions between humans and other system elements to optimize human well-being and performance. There are three main types of ergonomics: physical, cognitive, and organizational. The document discusses applications of ergonomics in engineering psychology, macroergonomics, seating design, and experiments. Benefits of ergonomics include decreased injury risk and increased productivity, efficiency, and morale.

3.  "Ergonomics (or human factors) is the scientific
discipline concerned with the understanding of
interactions among humans and other elements of
a system, and the profession that applies theory,
principles, data and methods to design in order to
optimize human well-being and overall system
performance. "(According to the International
Ergonomics Association )
 “A way of thinking about and planning work so that
it suits the capabilities and needs of the people”

7.  Physical Ergonomics are concerned with the
interaction of the body with the equipment and
the tools, starting right from the chair to the
computer. It also studies its effect on the body,
for example, repetitive disorder, workplace safety,
health and layout, musculoskeletal disorder and
posture.

8. COGNITIVE ERGONOMICS
Cognitive ergonomic
emphasizes the ways of
information processing by
the mind and its
presentation. It is related to
the motor function,
workload, decision-making
and memory-usage. This
helps in understanding the
interaction and relation of
the human mind with the
data presentation.

9.  Organizational ergonomic works on complete
optimization of the workplace, right from quality
management to teamwork. It includes managing
everything in the organization to make it a better
place to work.

11.  Engineering Psychology works on the
relationship between human and machines and
makes a continuous effort to improve the
relation. This might include changing the
location of the workplace, modifying the ways of
using machine or redesigning of the equipment.
In short, the main work of engineering
psychology is to make the machines 'user-
friendly' for the workers.

12.  Macro-ergonomics works on a wider aspect and
emphasizes more on the organizational
environment, history, goal, culture and design. It
concentrates more on the physical design and
the surrounding environment. Its aim is to set an
efficient work system and consequently improve
the employee satisfaction, safety, health and
productivity in the organization or workplace.

13.  Seating ergonomics can be defined as a
comfortable working posture with a natural
alignment of all your joints from head to toes.
Before discussing on how to set your computer
workstation, let’s have a look at the concept of
ergonomic seating (neutral body
positioning).This method of Ergonomic Seating
helps you reduce the stress and strain on the
muscles, tendons, and skeletal system thus
reducing the risks of developing ergonomic
problems.

16.  More than twenty technical subgroups within
the Human Factors and Ergonomics
Society(HFES) indicate the range of applications
for ergonomics. Human factors engineering
continues to be successfully applied in the fields
of aerospace, aging, health care, product design,
transportation, training, nuclear and virtual
environments, among others.

17.  Physical ergonomics is important in the medical
field, particularly to those diagnosed with
physiological ailments or disorders such as arthritis
(both chronic and temporary) or carpal tunnel
syndrome. Pressure that is insignificant or
imperceptible to those unaffected by these disorders
may be very painful, or render a device unusable, for
those who are. Many ergonomically designed
products are also used or recommended to treat or
prevent such disorders, and to treat pressure-related
chronic pain. Human factors issues arise in simple
systems and consumer products as well.

18.  Some examples include cellular telephones and
other hand held devices that continue to shrink yet
grow more complex (a phenomenon referred to as
"creeping featurism"), millions of VCRs blinking
"12:00" across the world because very few people can
figure out how to program them, or alarm clocks that
allow sleepy users to inadvertently turn off the alarm
when they mean to hit 'snooze'. A user-centered
design (UCD), also known as a systems approach or
the usability engineering life cycle aims to improve
the user-system.
