QUESTIONS AND ANSWERS
What is the iterative design process? ANSWER -A design approach that emphasizes
rapid iteration, exploration, and learning to improve designs.
What does the design diamond model represent? ANSWER -It illustrates the creative
process in design, including stages of generating and selecting ideas.
What are the implications of the design diamond model? ANSWER -It highlights the
importance of creativity and research in shaping design choices.
What is the difference between a sketch and a prototype? ANSWER -A sketch is a
preliminary visual representation of ideas, while a prototype is a more developed
model used for testing.
How can sketches be differentiated from prototypes? ANSWER -Sketches are often
rough and conceptual, whereas prototypes are functional and used to evaluate design.
What is the master/apprentice relationship in contextual inquiry? ANSWER -It is a
relationship where the researcher learns from the participant, contrasting with other
participant relationships.
What are the principles of contextual inquiry? ANSWER -Context, partnership,
interpretation, and focus.
,What are the stages of a contextual inquiry? ANSWER -Stages include withdrawal
and return.
What are some examples of design research methods? ANSWER -Interviews,
surveys, usability testing, and contextual inquiry.
What is Norman's execution-evaluation cycle? ANSWER -It describes the process of
executing actions and evaluating outcomes, highlighting the gulfs of execution and
evaluation.
What are the gulfs of execution and evaluation? ANSWER -The gulf of execution is
the gap between a user's intentions and the means to execute them; the gulf of
evaluation is the gap between the system's output and the user's understanding of it.
What are implementation, manifest, and mental models? ANSWER -Implementation
models refer to how a system is built, manifest models are how users perceive the
system, and mental models are users' internal representations of how the system
works.
What are affordances in design? ANSWER -Affordances are properties that suggest
how an object should be used, including false and hidden affordances.
What are metaphors in design? ANSWER -Metaphors are design elements that draw
on familiar concepts to help users understand new interfaces.
,How do visibility, constraints, and mappings relate to mental models? ANSWER -
They help users understand how to interact with a system and what actions are
possible.
What is the effect of modes in design? ANSWER -Modes can change how users
interact with a system, potentially leading to confusion if not clearly indicated.
What is the purpose of stories and storyboards in design? ANSWER -They help
convey design ideas and user experiences, differentiating from sketches and
prototypes.
What is paper prototyping? ANSWER -A low-fidelity prototyping method that uses
paper to represent interface elements for testing and feedback.
What is Fitts's Law? ANSWER -A model that predicts the time required to move to a
target area, influenced by the distance to the target and the size of the target.
What does the Gestalt perspective on human perception emphasize? ANSWER -It
emphasizes how people perceive visual elements as organized patterns or wholes
rather than as separate components.
What are the stages of a usability test? ANSWER -Stages include planning,
conducting, analyzing, and reporting the results.
Why is task design important for usability testing? ANSWER -Poorly designed tasks
can mask usability problems, leading to inaccurate test results.
, What is the Wizard of Oz testing principle? ANSWER -A method where a human
simulates the response of a system to test user interactions.
What are Nielsen's heuristics? ANSWER -A set of principles for user interface design
that help identify usability issues.
What is an effective heuristic evaluation process? ANSWER -It involves independent
evaluators assessing an interface against Nielsen's heuristics to identify usability
failures.
What are design patterns in interface design? ANSWER -Reusable solutions to
common design problems that provide a framework for creating effective interfaces.
What is the Model/View/Controller approach? ANSWER -A design pattern that
separates an application into three interconnected components to promote organized
code and user interaction.
How do tools evolve with design patterns? ANSWER -Tools develop alongside
design patterns, enhancing interface design capabilities but may also limit creative
thinking.
What is the Design Diamond? ANSWER -A framework that outlines the design
process, emphasizing exploration and iteration.
What are the properties of effective sketches? ANSWER -Distinct gesture, minimal
detail, appropriate refinement, suggest and explore, and ambiguity.
