quiz 2 Flashcards
Parts of the design thinking model
Empathize, Define, Ideate, Prototype, Test
Affordance
the relationship between the properties of the user and the capabilities of the artifact (backwards teapot)
What explains how an artifact works and is understood by developers and designers?
Conceptual model
What explains how a user perceives how an artifact or system should work and is often inaccurate?
Mental model
Double diamond model
Divergence and convergence
Finding the right problem and finding the right solution
Personas are a method most appropriate and useful in which stage of the design thinking model?
Empathize
A persona is typically developed using a single, real person as a model where this person represents a target user of your design
False
In chapter 2 of norman, he describes two knowledge gaps users must overcome to use a technology effectively
Gulf of execution/Gulf of evaluation
Affinity diagrams are a method of brainstorming that help designers generate and organize ideas, information, and observations to identify patterns and insights. They are most often used in which phase of design thinking?
Define/Ideate
The two basic types of knowledge knowing that (fact) and knowing how (steps) are called
Declarative and procedural
Short term memory is the human’s capacity to store a small amount of information in the mind for a short period of time, therefore as designers we should be mindful of how much info we present to the user
True
When designing an activity what is it important to know?
What does the user do
What do other people do
What does tech do
What does the documentation or other knowledge resources do
Norman calls this distribution of knowledge
Allocation of functions (who does what)
Small amounts of data can be made easier for a user to scan if they are structured, broken apart groups of data are called…
Chunks
Norman’s principle where activities are constrained to a particular sequence is called
Interlock (User can’t move forward until you have all appropriate info)
Type of constraint
Design principle where activities cannot be interrupted
Lock in
Design principle to prevent an activity
Lock out
According to norman, every design decision constraints future decisions
True
Norman’s 4 types of constraints are
Physical (legos, auto parts)
Cultural (conventions, standards, internationalization)
Semantic (situated actions, traffic lights, UI widgets)
Logical (what makes sense for the situation, mappings)
Designer constraints are
What’s possible
User constraints
What people can do, what is afforded by tech
Objects near each other appear grouped
Proximity
Objects that look similar appear grouped
Similarity
Our visual perception is biased to perceive continuous forms rather than disconnected segments
Continuity
