What is the main purpose of evaluation in HCI?
Improve hardware performance
Test usability and functionality of a system
Reduce software cost only
Replace the design phase
Evaluation should be considered at which stage of the design life cycle?
Only after implementation
Only during design
At all stages of the design life cycle
Only before deployment
Which of the following is a goal of evaluation?
Increasing memory size
Identifying specific usability problems
Improving network speed
Writing source code
Cognitive Walkthrough mainly evaluates:
System performance
How well a system supports user learning
Visual design aesthetics
Database efficiency
Cognitive Walkthrough was proposed by:
Nielsen
Molich
Polson et al.
Norman
Who usually performs a Cognitive Walkthrough?
End users
System administrators
Experts in cognitive psychology
Graphic designers
Which question is asked during a Cognitive Walkthrough?
Will the system crash?
Will the user understand the system's feedback?
Is the database secure?
Is the code optimized?
Heuristic Evaluation is based on:
User interviews
Usability heuristics
Physiological sensors
Performance testing
Heuristic Evaluation was proposed by:
Polson
Card
Nielsen and Molich
Shneiderman
Which is an example of a heuristic?
Faster processor
Consistency and standards
Database indexing
Network reliability
Heuristic Evaluation helps to:
Debug the design
Replace user testing completely
Measure emotions
Write system code
Model-based evaluation uses:
Questionnaires
Formal models
Eye tracking
Interviews
Which of the following is a model used in model-based evaluation?
MVC
GOMS
PAC
Seeheim
Review-based evaluation relies on:
Observing users
Written reviews
Experiments
Physiological measurements
Evaluation through user participation usually occurs:
Before requirements analysis
Early design stage
Later stages of development
Before any prototype exists
Experimental evaluation is:
Informal
Controlled
Unstructured
Subjective only
An independent variable (IV) is:
What is measured
What is changed
User behavior
System output
A dependent variable (DV) is:
What is changed
What is measured
The hypothesis
The task
A hypothesis is:
A design rule
A prediction of outcome
A data collection tool
A usability guideline
A null hypothesis states:
A strong effect exists
No difference between conditions
User preference
Maximum usability
In a within-groups design:
Each subject tests one condition
Each subject tests all conditions
No users are involved
Only experts participate
Between-groups design:
Needs fewer users
Needs more users
Has no variation
Uses the same users
The Think-Aloud method requires users to:
Remain silent
Write reports
Verbalize their thoughts
Answer questionnaires
One disadvantage of Think-Aloud is:
Very expensive
May alter task performance
Needs special sensors
Requires many users
Cooperative Evaluation differs because:
User is silent
Only evaluator talks
User and evaluator collaborate
No tasks are performed
Protocol Analysis focuses on:
Interface colors
Recording user actions
Writing code
System speed
Which recording method is cheapest but limited?
Video recording
Audio recording
Paper and pencil
Eye tracking
Post-task walkthrough happens:
During the task
Before the task
After the task
Without a task
Interviews are:
Objective
Quantitative
Subjective
Automated
Questionnaires are useful because they:
Are flexible
Reach many users quickly
Need no design
Replace experiments
Eye tracking measures:
Memory
Cognitive processing
User satisfaction
Errors only
Fixations indicate:
Rapid eye movement
Level of difficulty
System speed
Error rate
Physiological methods measure:
Code quality
Emotional response
Interface layout
Task time
Field studies are valued because they are:
Cheap
Fast
Realistic
Simple
Laboratory studies are usually:
Uncontrolled
Informal
Controlled
Random
Combining evaluation methods helps to:
Increase bias
Reduce reliability
Improve results
Eliminate users
Evaluation can be conducted in:
Laboratory only
Field only
Collaboration with users
All of the above
Automated analysis often uses:
Interviews
Video tools
Questionnaires
Heuristics
Which method is NOT a query technique?
Interviews
Questionnaires
Eye tracking
Surveys
Choosing an evaluation method depends on:
Programming language
Time and resources available
Hardware brand
Developer preference only
