Purdue CGT 256: Final Exam - Foundations of
Graphics and Visualization Techniques
How to make a persona - correct answer ✔✔Use interview synthesis results, design requirements, and
the root problem to empathize with users and create blank.
Usability - correct answer ✔✔The extent to which a product can be used by specified users to achieve
specified goals with effectiveness, efficiency and satisfaction in a specified context of use.
5 components of usability (Nielsen) - correct answer ✔✔1. Learnability
2. Efficiency
3. Memorability
4. Errors
5. Satisfaction
Learnability - correct answer ✔✔Answers "is it easy to accomplish basic tasks the first time?"
Nielsen's first usability component.
Efficiency - correct answer ✔✔Answers "Can users accomplish tasks quickly?"
Nielsen's second usability component.
Memorability - correct answer ✔✔Answers "How easy is it to use after time away?"
Nielsen's third usability component.
Errors - correct answer ✔✔Answers "How many errors are there, and how severe and how easy to
recover are they?"
Nielsen's fourth usability component.
Satisfaction - correct answer ✔✔Answers "How pleasant is the experience?"
Nielsen's fifth usability component.
, User Centered Design - correct answer ✔✔Focuses on designing around what a user needs to do, how
they want to feel while doing it, and optimizing product interactions when they happen. Start with
research, gather feedback and iterate through design.
User Error - correct answer ✔✔When this term is used, it is indicative of design error and likely bad
usability.
Without good user-centered design, the user will be confused and blame the designer for it not working,
while the designer will blame the user. This wastes both parties time.
What do you ask users? - correct answer ✔✔NOT what they want
Goals
Activities
Processes
Frustrations
What works
UCD and Design as art vs Engineering - correct answer ✔✔Engineering = making something that works
UCD = making something with usability that appeals to users
Steps of UCD - correct answer ✔✔1. Research
2. Concept Design
3. Development
4. Evaluation
ReCoDE
Sketch - correct answer ✔✔A drawing of potential user interface layout, with some labels and marked
functionality or program flow.
Wireframe - correct answer ✔✔A more intricate drawing of a user interface, with detailed labels and
clear grouping of content. Usually built using software, however, can be done carefully by hand.
