1
Question
What is the core focus of Human-Computer Interaction when designing interfaces?
Page 4
Answer
HCI focuses on the interaction between the user and the task through the interface, rather than solely on the interface itself.
2
Question
How does focusing on the task rather than the interface lead to innovative design solutions?
Page 4
Answer
Focusing on the interface produces iterative cosmetic tweaks, whereas focusing on the overarching task allows revolutionary redesigns like autonomous smart thermostats.
3
Question
Why is swiping a credit card considered an operator rather than the true user task?
Page 6
Answer
Swiping a card is merely the mechanism used to execute the broader goal of completing a purchase.
4
Question
What are the five recommended guidelines for accurately identifying a user task?
Page 7
Answer
Watch real users, talk to them, start small with individual interactions, abstract up, and remember that you are not your user.
5
Question
How does the 'abstract up' method uncover the true scope of a user's task?
Page 7
Answer
The designer starts from small observed actions and repeatedly asks why the user performs them until reaching the broader goal.
6
Question
Why must designers adhere to the principle that 'you are not your user'?
Page 7
Answer
Designers must leave behind personal preconceptions because products must accommodate the entire diverse population performing the task.
7
Question
How does usefulness differ from usability in interface evaluation?
Page 8
Answer
Usefulness means an interface allows a task to be accomplished. Usability determines how easily and effectively the user can perform that task.

Question
How is cognitive load formally defined within human-computer interaction?
Page 8
Answer
Cognitive load is the total mental effort being used in working memory.
9
Question
In what way do GPS navigation apps improve upon traditional paper maps?
Page 8
Answer
Navigation apps offload mental route planning and location tracking from working memory onto the computerized interface.
10
Question
What are the three primary roles humans can play in human-computer interaction models?
Page 11
Answer
Processor, predictor, and participant.
11
Question
How does the processor view conceptualize the human user in an interactive system?
Page 11
Answer
As a sensory processor that receives input and produces output, functioning similarly to an internal computer component.
12
Question
What is the primary requirement for an interface designed under the processor view?
Page 12
Answer
The interface must fit within known human physical, perceptual, and memory limits.
13
Question
How are interfaces evaluated when treating the user as a processor?
Page 12
Answer
Through quantitative experiments that gather numeric measurements of task completion speed and stimulus reaction times.
14
Question
What cognitive elements are central to the predictor view of the user?
Page 13
Answer
The user's knowledge, prior experience, expectations, and internal thought processes.
15
Question
What must an interface achieve when designed for a user as a predictor?
Page 13
Answer
It must fit existing human knowledge, leverage what users know, and help them predict outcomes of their actions.
16
Question
Which evaluation methods are characteristic of the predictor view of the user?
Page 13
Answer
Qualitative ex situ studies, such as task analyses and cognitive walkthroughs.
17
Question
How does the participant view expand beyond the scope of the predictor view?
Page 14
Answer
It considers the surrounding environment, competing tasks, social interactions, and available cognitive resources rather than isolating one user on one task.
18
Question
Why does the participant view require in situ evaluation methods?
Page 14
Answer
System usability depends on the authentic, real-world context where external distractions and competing tasks occur.
19
Question
How does evaluation setting differ between ex situ and in situ studies?
Page 13
Answer
Ex situ studies take place in controlled, inauthentic lab environments. In situ studies take place within authentic, real-world contexts.
20
Question
Why is a two-second turn warning insufficient when designing navigation for a participant user?
Page 16
Answer
Real-world driving involves contextual demands such as high speeds, passenger distractions, and traffic negotiations that require early advance warning.
21
Question
Why does manual timesheet entry often fail when assuming a processor model of the user?
Page 17
Answer
Human workers switch rapidly between micro-tasks, making precise mechanical time-tracking across tasks unrealistic.
22
Question
How does an online classroom interface support the user from a predictor perspective?
Page 17
Answer
It provides structured visual outlines, progress meters, and transcripts to offload cognitive load and help users anticipate content.
23
Question
What is the relationship between user experience and user experience design?
Page 18
Answer
User experience is the emergent phenomenon resulting from human-interface interactions that always exists, while design is the intentional attempt to shape it positively.
24
Question
What factors define user experience at the individual level?
Page 18
Answer
Personal identity factors, demographic traits, prior expectations, and emotional states such as joy or frustration.
25
Question
How can interface changes impact user experience at the societal level?
Page 18
Answer
They can facilitate large-scale social movements unintentionally or intentionally reflect and normalize evolving cultural relationships.
26
Question
How does analyzing an interface from the predictor view differ from the participant view?
Page 21
Answer
The predictor view evaluates how an interface matches immediate task needs and command execution. The participant view examines broader interactions with other tasks, social activities, and overall life changes.
27
Question
What is the primary objective of an interface that mediates between users and tasks?
Page 22
Answer
An effective interface allows the user to spend as much time as possible focusing on the task rather than operating the interface itself.
28
Question
Across which three distinct levels does user experience occur?
Page 24
Answer
User experience occurs at the individual user level, the group level, and the societal level.
29
Question
What is the definition of the gulf of execution?
Page 25
Answer
The distance between a user's goals and the execution of the physical actions required in the interface to realize those goals.
30
Question
What is the definition of the gulf of evaluation?
Page 26
Answer
The distance between the physical effects of system actions and the user's understanding and assessment of those results.
