UX Research Flashcards
GOMS
goals
operators
methods
selection rules
GOMS is used to…
measure the intent and process of a system
Goals asks…
“What do you want to do?” focus on intent
Operators seeks to understand…
“What tools do you have as a person to get the job done?” focus on cognitive hurdles of the task
Methods looks at…
“How can the operators (tools) be used to complete the task?” What ways can we effect change on the system with the operators we have.
Selection rules measures…
what options an interface or product offers to assist users in accomplishing their goals, e.g. a light switch has 2 modes, Photoshop has 1000s of options
KLM
Keystroke Level Modeling
KLM is …
the mathematical study of a tool’s efficiency, motion study for digital products
KLM is intended to…
measure completion tasks for expert users, time to completion (clicking a mouse, pressing a key)
KLM makes use of this law
Fitt’s Law
Fitt’s Law equation
ID (index of difficulty) = log2(D/W + 1)
D = distance between targets W = size of the targets
golden rule about questions
don’t ask Yes/No questions
lead with something that allows to elaborate
5WH model
Who, What, When, Where, Why, How to help develop questions based on goal
way to model questions and assumptions
row for questions > each question in a column, row for assumptions underneath each question
when to break the rules on leading questions
when you suspect the response will be opposite to the hints you provide in questioning
build trust with participant and validate previous comment
when to break the rules on shallow questions
to help ease participants into activity at the beginning of the session
when to break the rules on personal bias questions
go deeper into convo by getting the participant to disagree with what you say
the basic structure of the question
setup + area of inquiry
laddering
segue to next question
the setup is…
the purpose the what (description), why (explanation), how (process), when (situation), where (context)
“when you are doing x…”
area of inquiry
what you want to learn about
“how do you decide…”
laddering
asking the participant to go into more detail or to explain the rationale. has an automatic “Why?” behind them?
things to remember when writing your questions
relate back to research goals
open up additional areas of discussion
progress the overall conversation
a common tactic to avoid generic answers to abstract questions
ask to think about a recent, significant life event and how that relates to the experience in question
give a scenario
how to use different types of questions
remember to mix up 5WH
