Section 4 - User Centered Design Process Flashcards
During the Ideation phase, how do you increase creativity?
Use IDEO methods and friends
Immerse yourself in the world you are designing for (gathering inspiration)
- Collect examples from existing systems
- Collect things that irritate you
- Collect things that seem really good
- Same things that inspire you
- remember clever ideas
- Generate ideas constantly
- sketching
Brainstorm in groups
Chat with others (bounce ideas off of people)…
What is sketching and why use it?
Sketching enables you to think through ideas and variations, and convey design ideas to others early in the design phase.
Why use sketching?
Early ideation that allows:
- risk-taking
- exploring variations
Allows you to think through ideas - externalize your through process
Active form of brainstorming
What are the summary points of ideation?
What is a prototype?
In what ways is a protype defined less by form, and more by its function?
Why prototype?
What should you prototype?
What are the prototyping phases?
What is a low-fidelity protype and why use it?
How would you make a low-fidelity prototype?
Why use sketching as a low-fidelity prototype?
Why use sketching as a low-fidelity prototype?
- Forces you to visualize how things come together
- Communicates ideas to others (and oneself) to inspire new designs
- Drawing ability irrelevant
- Disposable
- If you can’t afford to throw it away, it’s not a sketch
- Promotes constructive criticism
- Freedom
- Abstracts away details, opposite of an engineering drawing, which is tight and precise
What is a story board?
What is an example of a storyboard
What are the properties of a “Good” storyboard?
What are some tips for paper prototyping techniques?
What are some issues with low-fidelity prototyping?
In general what are the prototype “types”/dimensions?
How do the prototype dimensions limit functionality?
What are some suggested prototyping mock-up tools?
What are some prototyping tools for interface building?
What is the prototyping system “Wizard of Oz”?
Common problem: It’s difficult to prototype some piece of functionality
need: test whether it is actually good before building it
Solution: fake it! Make the interaction as authentic as possible
Key: user has no idea that the interaction is being faked.
The point: Up until the point the wizard is discovered, the thoughts, feelings, and actions of Dorothy and the others were all genuine. They were genuinely expeirencing what it would be like to talk to a powerful and terrible wizard.
What are the issues with the Wizard-of-Oz prototype method?
What are issues with High-Fidelity Prototyping?
What is video prototyping?
In summary what are the 2 dimension of prototypes?
Which prototyping method is best?
In general how do we integrate prototyping into the overall development cycle?
There are three general methods for managing this interaction:
- Evolutionary
- modular (incremental)
- throw-away
What is an evolutionary prototype?
What is a modular (incremental) prototyping
What is throw-away prototyping?
In general what is the prototyping summary?
