Ergonomics

The science of designing and arranging things so that people can use them easily and safely.

Ergonomics

The study of the interaction between people and machines and the factors that affect the interaction.

what does ergon and nomos stand for?

Inefficiency

Accidents, injuries and errors
User difficulties
Low morale and emphaty

How can we tell if something needs an ergonomics? Enumerate the five basis of spotting ergonomics.

Physical

Most commonly known form of ergonomics, and for good reason. It deals with the physical load on the human body when performing activities.

Cognitive

Method of designing and arranging information and data to create a light cognitive load. Perception, memory, reasoning, and motor response all affect how someone interacts with and performs their work.

Organizational

Combines the knowledge gained from other areas of the factory, like physical and cognitive ergonomics, to optimize safety and efficiency across the entire organization.

Human factor engineering

The application of human factors knowledge to the design and construction of equipment, products, work systems, management systems, and tasks.

Ergonomics

Its purpose is to improve the performance of systems by improving human machine interaction.

By designing in a better interface or by designing out factors in the work environment.

How can ergonomics be done?

Ergonomics

The following are the 3 ways of applying what?
Designing the user interface to make it more compatible with the task and the user.
Changing the work environment to make it safer and more appropriate for the task.
Changing the task to make it more compatible with user characteristics

Human Machine Environment

What is the focus of ergonomics?

Physical Anatomical Physiological Psychological

The 4 ways on how we can evaluate basic interactions

Machine > Human

Feedback and display of information. Machine may exert forces on the human due to vibration, acceleration, etc. Machine surfaces may be excessively hot or cold and a threat to the health of the human.

Machine > Environment

Machine may alter working environment by emitting noise, heat, noxious gases.

Anatomical Physiological Psychological

Three evaluation of human > machine interaction

Human > Machine interaction

The basic control actions performed by the human on the machine. Application of large forces, ‘fine tuning’ of controls, stocking raw materials, maintenance, etc.

Human > Environment interaction

Effects of the human on the local environment. Humans emit heat, noise, carbon dioxide, etc.

Environment > Human

Influences the human’s ability to interact with the machine or to remain part of the work system (owing to smoke, noise, heat, etc.).

Human factor engineering

Based solely on the relationship between the worker and his or her mechanical or technological equipment.

Ergonomics

Promotes holistic approach which considers the physical, cognitive and organizational environment.
