Ergonomics
What is "Adjustability" in a product?
The ability of a product to change size to accommodate a wider range of percentiles (e.g., an adjustable chair).
This type of data is descriptive and captures characteristics like how people feel or their perceptions.
Qualitative data.
This field of study analyzes the mechanics of living organisms, including the operation of muscles, joints, and tendons.
What is Biomechanics.
Derived from Greek and Latin roots, what does the word "Anthropometrics" literally mean?
People measure (or measuring people).
If a person is in the 50th percentile for height, what does that mean in relation to the rest of the population?
50% of the population is at that height or below.
Providing a selection of different fixed sizes (like shoe sizes) to cater to the majority of the market is known as what?
Range of sizes.
A person's sense of physical or psychological tiredness.
What is fatigue?
The physical space between two objects.
What is clearance?
Data collected by someone other than the user.
What is secondary data?
The average range of a given population
What is the 50th percentile range?
The type of human factor that deals with subjects that are work-related.
What is physical ergonomics?
The way in which something is regarded, understood or interpreted.
What is perception?
A range that a person can stretch to touch or grasp an object from a specified position.
What is reach?
Data used in classification or division of objects into discrete groups
What is nominal data?
The top 1% of a given population
What is the 99th percentile?
How mental processes, (memory, reasoning, motor response and perception), affect the interactions between users and other components of a system.
What is cognitive ergonomics?
The level of vigilance, readiness or caution of an individual.
What is alertness?
Mistakes made by users, some of which can result in catastrophic consequences for people, property and the environment.
What is human error?
A ratio scale allows you to compare differences between numbers.
What is the ratio data scale?
Designers will design products for this range as it encompasses the largest amount of people
What is the 5th to 95th percentile?
The type of human factor that is concerned with the management of systems
What is organizational ergonomics?
Name the three basic stages of the Human Information Processing System.
Input, Sensory Process (or Processing), and Output (or Motor Response).
These factors can be considered to maximise performance of a user in a role and reduce the risk of accidents.
What are the workplace environmental factors?
A statistical data type that exists on an arbitrary numerical scale where the exact numerical value has no significance other than to rank a set of data points.
What is ordinal data?
Why do designers often exclude the bottom 5% and top 5% of the population (the 0-5th and 95-100th percentiles)?
It becomes too expensive to design for these extreme outliers.
