1 A radio volume control might be designed to be a dial or a slider which provides a continuous control of amplification - which the functionality the user is expecting. These are examples of which kind of control coding? Shape Size Mode of operations Labelling Colour Location INCLUSIVE DESIGN: In our guest lecture on inclusive design, barriers for people with limitations - leading to disability in their daily lives - can be caused by: Attitudinal factors: Systemic factors: Barrier by society as a whole eg.(BLM) Physical factors : requires manual dexterity Political factors You are designing warning signs for a construction site. According to the Helander textbook, what are the information processing stages you need to consider when designing this sign? Visibility, perceived relevance, understanding, action Attention, recognition, avoidance, safety Attention, memory, recognition, motor Colour & shape, recognition, action, safety When building a system diagram of a powered machine that will consume gasoline during operation, we represent the flow into the machine of gasoline as a flow of: Energy Mass Information Pollution When constructing a system identification matrix, which kinds of requirements are used? Product characteristics All of the above Constraints Functional requirements In terms of control. Turning a wheel to the right to turn a cart to the right is an example of: Using short term memory A natural mapping Expectation management (??) A population stereotype A 1:1 mapping Control response compatibility

2 If you design a vehicle cockpit that is large enough to fit up to 95th percentile males, and small enough that 5th percentile females can reach all the controls easily, then what fraction of the population will have problems using your design? Over 10% 10% Under 10% About 5% Over 5% A set of “rules” providing general advice for evaluating usability in your design is called a: Fast usability check Heuristic test Memory reduction method Ease of use scale Usability checklist In terms of Rasmussen’s model of decision making, when you are adjusting your bicycle position to stay between the lines in the bike lane, you are engaging in what kind of decision making? Memory based Population stereotype Experience based Skill based Rule based Knowledge based I am operating machinery outside and can’t see the control panel because of the sun reflecting off the metal panel into my eye. This is an example of: (pick one) Too little brightness Excess brightness A control problem Indirect glare Direct glare Who is NOT a co-user of a hospital bed? Nurse Cleaning staff Patient Doctor Visitors / family Pharmacist The statement “the product must resist corrosion” is an example of: (pick one)

3 Constraint None of the above Title for a situated use case Product characteristic Functional requirement How long does it take for a typical person’s eyes to adapt to the darkness outside at night after exiting from a brightly lit room? About 10min About 30min About 60min About 3min About 5min Situated use case vs usage scenario Which of the following is true? SUCs and USs are both represented with flowcharts SUCs determine specific cases of the application of a US SUCs must reference personas, but USs must never reference personas A good US does not mention specific product parts or materials, but a good SUC can mention them. When professional designers were studied; what was observed when they used “disability simulators” to examine their design problem, compared to just examining the design directly? They discovered many more problems and barriers They discovered a few more problems and barriers They discovered about the same number of problems They discovered a few less problems and barriers They discovered far fewer problems and barriers The statement “an orthopedic surgeon goes to work on a rainy autumn day” is an example of: (pick one) Constraint None of the above Title for a SUC Functional requirement Product characteristic I am operating machinery outside and can’t see the control panel because the sun is shining in my eye making the panel seem black. This is an example of: (pick one) Excess brightness Direct glare Too little brightness A control problem
