Human Factors Engineering

1. Human Factors Engineering Why Smart People do Dumb Things.

2. Nuclear and renewables:a well-rounded offering • Nuclear and renewable energies are complementary • Two growing markets • Nuclear: confirmed benefits of AREVA's integrated model

3. AREVA across the globe

4. Global Human Factors Expertise Diverse Team Experience MCR design and upgrades NUREG-0711 & NUREG-0700 Function Allocation Task Analysis Ergonomic Analyses Usability HSI Design and Evaluation AREVA’s Human Factors Expertise

5. Today’s Objectives By the end of today’s session, you will be able to… • Define the term “Human Factors” • Discuss how poor human factors design can influence human performance • Identify and use selected human factors principles to improve human performance

6. The Monkey Business Illusion

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

11. 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.

23. Visibility Feedback Natural mapping Affordances Constraints

24. Visibility and Feedback Principle #1: Make relevant parts visible. Principle #2: Give each action an immediate and obvious effect

25. 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.

26. Natural Mappings • Mapping = the relationship between two things • Natural mappings can be • Cultural • Biological • Spatial Principle #3: Capitalize on the concept of natural mappings

27. Natural Mappings

28. Natural Mappings

29. 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

30. Affordances

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

32. 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

34. Human factors guidelines can help us optimize a user’s performance. Human factors guidelines can help us optimize a user’s performance.
