Humans are
hardwired for
certain types of
behavior.
We’re inherently good at some things… and we’re inherently not good at others.

What is Human Factors?
• HFE is a systematic approach to guide the human interactions with a facility (say, a “control room”) to ensure that all functional aspects of human involvement are achievable without introducing opportunities for human error.
• HFE considers human...– Capabilities– Limitations– Characteristics– Behaviors – Motivations
…as they impact the design of structures, systems and components.

DESIGNING FOR HUMAN FACTORS

Visibility and Feedback
Principle #1: Make relevant parts visible.
Principle #2: Give each action an immediate and obvious effect
![Page 25: Human Factors Engineering](https://reader036.fdocuments.us/reader036/viewer/2022081418/5681448f550346895db12908/html5/thumbnails/25.jpg)
Visibility and Feedback
Sound can be used to provide similar information.
When the electric engine is engaged, the Prius is quieter than a vacuum cleaner.

• Mapping = the relationship between two things
• Natural mappings can be – Cultural – Biological– Spatial
Natural Mappings
Principle #3: Capitalize on the concept of natural mappings
![Page 27: Human Factors Engineering](https://reader036.fdocuments.us/reader036/viewer/2022081418/5681448f550346895db12908/html5/thumbnails/27.jpg)

Affordances
• Affordance is a property of the object. They provide strong clues to the operation of things.
• Suggest how the object should be used– “Verb”-able
• Users know what to do just by looking at the object.– No instructions needed!
• Examples– Door plates – Knobs – Button

Principle #4: Use the affordances of objects to help infer their use

Constraints
• Constraints limit how the design can be used• Types:
– Physical– Square object and round hole
– Cultural– Light switches
– Logical– Order (1,2,3 or a, b, c)
Principle #5: Restrict the kind of interaction that can take place at a given moment

Some good human factors resources…
• Checklists and guidelines– NUREG-0700, Rev. 2, “Human System Interface Review”– MIL STD 1472, “Design Criteria Human Engineering”
• Professional Societies– Human Factors and Ergonomics Society (HFES)– Electric Power Research Institute (EPRI)
• Web Resource– Jacob Nielsen’s 10 Usability Heuristics (
http://www.nngroup.com/articles/ten-usability-heuristics )
• Books– Human Factors Engineering and Design, by Sanders and McCormick– Kodak's Ergonomic Design for People at Work, by The Eastman
Kodak Company
