Human Computer Interaction

What is HCI?

This field studies how humans
interact with technology.

What is accessibility?

The principle stating that a
design should be usable by
people with varying abilities.

What is Human-Centered
Design?

This design philosophy places
users at the center of development.

What is efficiency?

This usability attribute
measures resources spent
completing tasks.

What is user satisfaction?

HCI aims to improve both
productivity and this.

What is iterative design?

This process repeats cycles of
design, evaluation, and
refinement.

What is learnability?

The usability attribute
describing how easy a system
is to learn.

What is Recognition
Rather than Recall?

Users should not be forced to
memorize information
according to this heuristic.

What is Visibility of
System Status?

This heuristic emphasizes
keeping users informed about
system activity.

What is 10?

Nielsen proposed this number of
heuristics.

What are Consistency and
Standards?

Users expect common
interface patterns due to this.

What is user control and
freedom?

Undo and redo functionality
support this heuristic.

What is Match Between
System and the Real
World?

Interfaces should use familiar
language according to this
heuristic.

What is Flexibility and
Efficiency of Use?

This heuristic emphasizes that
systems should accommodate
both novices and experts.

What is feedback?

Information users receive after
performing an action.

What is a signifier?

A visible clue that tells users
where to act.

What is an affordance?

This concept suggests how an
object may be used.

What is a constraint?

A restriction limiting possible
actions.

What is mapping?

The relationship between
controls and the outcomes.

What are mental models?

Users develop expectations
called this.

What is intuitive?

Norman’s principles
emphasize this type of design.

What is Gestalt Theory?

This theory explains how
humans organize visualize
information.

What is proximity?

Items placed close together
are perceived as related
according to this principle.

What is Closure?

Humans perceive incomplete
shapes through this principle.

What is Continuity?

Users tend to follow smooth
visual paths due to this
principle.

What is attention?

The principle of continuity
helps guide this in humans
when designing interfaces.

What is visual
organization?

Gestalt principles support this
in design.

What are patterns?

Human perception tends to
seek this.

What is attention?

The ability to focus on specific
information while ignoring
distractions.

What are the senses?

Perception involves interpreting
information received through
these.

What is working memory?

This memory system holds
information briefly during
processing.

What is user experience?

Perception and attention are
heavily influenced by this.

What is attention?

Information that enters working
memory is determined by this.

What is cognitive load?

Mental effort required to
complete a task is known as
this.

What are motor systems?

The Model Human Processing
contains perceptual, cognitive,
and these systems.

What is a journey?

Storyboards are used to
illustrate this for a user.

What is ideation?

During this process, the
generation of several ideas is
prioritized over the quality.

What are user workflows?

Storyboards are used to
communicate these.

What is usability testing?

High-fidelity prototypes often
support this type of testing.

What is convergent
thinking?

The process of using logic and
problem-solving to narrow down
several possibilities into a single,
well-defined solution.

What is creativity?

Ideation is used to promote
this.

What is a low-fidelity
prototype?

An HCI team creates paper sketches to test
navigation concepts with users before investing
resources in coding. This type of prototype is valued
because it is inexpensive, quick to modify, and
encourages design exploration.

What is efficiency?

Time-on-task measures this.

What is a story?

Scenarios tell this for a user.

What is qualitative
research?

This type of research focuses on
understanding behaviors and
motivations.

What is evaluative
research?

Research used to assess
designs is called this.

What is generative
research?

Research performed to
understand users before
design is called this.

What is contextual
inquiry?

Observing users in their natural
environment is known as this.

What is task completion
time?

Keystroke-Level Model (KLM) is
used to estimate this.
