user centred design and prototyping Flashcards
what are the 4 stages in the model of ucd
research
requirements
design
evaluate
research
understanding users needs via collecting data
requirements
what problems will be solved for the user
design
create solutions based on requirements
evaluate
testing if youve made the right thing for the user population
id improvements before releasing the product
in which two ways can we represent users
personas
scenarios
personas
architypes of target users that create empathy between the designer developer and target user
what are the two purposes of personas
help connect with the persona via having biographical details so it feels more like a character in a story
helps to design by giving the information we need
scenarios
short stories putting the persona into motion
what do scenarios need to do
make the goal, context of using the system and how the system is used clear
design thinking
using design processes where it might be useful
storyboarding
walkthrough of a scenario and adding more detail to it allowing us to think more deeply about the scenario so we can create a better solution
sketching
focus on the ui and what it will look like through quickly sketching it
what is a benefit of sketching
helps come up with multiple alternatives faster
OPQRST sketching
open ended; unrestricted
plentiful; multiple ideas
quickly
refinable
simple
timely; provides context and value immediately
prototyping PQRSTU
proof; not the final product
quick
rough
simulate features
test
user; think like the users
prototyping
simulating what the end product will look like
what are some positives of prototyping
quick and low cost
multiple iterations and testing them
identify problems early in the process
usually interactive
soft prototyping
well understood and already exists e.g. apps
hard prototyping
doesnt exist yet
used to validate/prove a theory
no clear mental models
