Q6 | Which is the best definition of an interaction paradigm?
  • In broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., WIMP, mobile, tangible)
  • An idea from the world that is used in the interface to help the user understand what to do (e.g., click on tabs to change window contents, use shopping cart to store items to purchase)
  • What the human does to make inputs and receive information from the system (e.g., click and drag an object, talk to an object, move self closer to an object, converse with an entity, etc)
  • The conceptual model used to guide the design of the interface.
Answer: In broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., WIMP, mobile, tangible)
Q7 | What is an "affordance" according to Norman (1999):
  • Property of an object that indicates to people how to use the object.
  • The return on investment of the user­centred design process.
  • The opportunity cost of not using user­centred design.
  • An instruction on an interface signalling how to use the interface.
Answer: Property of an object that indicates to people how to use the object.
Q8 | According to Rogers et al. (2011) what was the primary reason for the success of the iPod?
  • Powerful functionality
  • User experience
  • Access to content
  • Conceptual design
Answer: User experience
Q9 | Which of the following is a design implication of our understanding of human attention?
  • Tactile feedback should make the same kinds of distinctions that a
    person would feel in the world (e.g. pushing vs. pulling)
  • Text should be legible and distinguishable from its background under
    different lighting conditions.
  • Avoid cluttering the interface with more information than is needed at
    the present moment for the user.
  • None of the above.
Answer: Avoid cluttering the interface with more information than is needed at
the present moment for the user.
Q10 | A question format that collects users opinions on a verbal scale (eg. strongly disagree to strongly agree) is called what?
  • A psychometric scale
  • A Likert scale
  • A questionnaire
  • An open-response questionnaire item.
Answer: A Likert scale
Q11 | Sequential or series testing is
  • running the system with line data by the actual user
  • testing changes made in an existing or a new program
  • is checking the logic of one or more programs in the candidate system
  • making sure that the new programs do in fact process certain transactions according to Specifications
Answer: is checking the logic of one or more programs in the candidate system
Q12 | Which of these belong to the four criteria used to critique a cognitive walkthrough success or failure story:
  • Will the user be trying to achieve the right effect?
  • Will the user know that the correct action is available and will achieve the desired effect?
  • . If the correct action is taken, will the user see that things are going ok?
  • All of above
Answer: All of above
Q13 | Regarding the measurement of usability attributes:
  • Reliability is measured by performing common use cases
  • Errors are measured by counting minor and catastrophic errors made by users.
  • Learnability is determined by measuring the time it takes to explain an interface to a new user
  • users are needed to measure efficiency
Answer: Errors are measured by counting minor and catastrophic errors made by users.
