Study Notes

Ergonomics

Ergonomics is derived from Greek words meaning "work" and "natural laws".
It's a multidisciplinary field combining contributions from psychology, engineering, industrial design, graphic design, statistics, operations research, and anthropometry.
Ergonomics aims to optimize human well-being and system performance by understanding interactions between humans and elements of a system.
It's essential for creating healthier and more productive work environments.
Ergonomics seeks to ensure that tasks, functions, information, and the environment are suitable for each user, considering their capabilities and limitations.
The terms "human factors" and ergonomics are synonymous.
Ergonomics is employed to improve health, safety, and productivity.
It focuses on user-equipment-environment interactions, and the design of equipment that aligns with human body and cognitive abilities.

Golden Ratio

Also known as the golden mean or golden section, this ratio is a recurring proportion in geometry.
Represented by the Greek letter Phi (φ) and calculated as (1 + √5)/2 ≈ 1.618.
It appears in geometric shapes such as pentagrams and logarithmic spirals.
This ratio can be observed in diverse fields, including mathematics, art, nature, architecture, and everyday designs like postcards, playing cards, and wide-screen televisions.

Human Factors

A human factor is a physical or cognitive property of an individual or social behavior that influences the functioning of technological systems.
Human dimensions are measured in standing, sitting, and other static conditions considering different parts of the body.

Workplace Ergonomics

The work area needs approximately 8 to 12 square meters per employee.
Work placement ergonomics focuses on work-related designs that improve health, safety, and productivity for workers.
Designers create ergonomic workspaces, considering factors like desk heights, chair features, and reaching distances to enhance the work environment.
Measurements for different kinds of workspace layouts and measurements for human reach zones in all kinds of situations are given

Practical Work Task

Find a product example that demonstrates the Golden Ratio, showcasing its advantages and disadvantages.
Locate and describe an interesting designed workplace with its advantages and disadvantages.
Examples must be different from the provided lecture material.
