Introduction To Human-Computer Interaction Flashcards
List the 6 parts of an interview structure:
1) Introduction 2) Warm up 3) General Issues 4) Deep Focus 5) Retrospective 6) Wrap up: summary
List the four steps for identifying the competition:
a. Identify the main product goals b. Write a product description c. Write an audience profile d. Define key dimensions
Name 8 of the most popular research methods:
- interviews
- contextual inquiry
- thinking aloud
- focus groups
- observations
- user tests
- surveys
- probes/diary studies
List important characteristics of the “interview” research method:
- Users needed: 5
- Life cycle stage: early design stages
- Advantage: flexible, in-depth, experience probing
- Disadvantage: time-consuming, hard to analyze and compare
- Variations: contextual inquiry, guided speculation
Three steps for forming the goals of your research plan:
- Collect the issues
- Prioritize goals (importance x severity)
- Rewrite them as questions
What are the three principles for user-centered design:
- Early focus on user and tasks
- Empirical measurement of product usage
- Iterative Design
What are four of the biggest mistakes a designer can make:
- Using featurism
- Machine Oriented Design
- A Premature product release
- Next bench design
What process is used for “user-centered design?”
Iterative Design Process
What is the dual-process theory?
System 1: (95%)
- Intuition & Instinct
System 2: (5%)
- Rational thinking
What is HCI:?
- How humans interact with computers
What is the main purpose of metrics?
Identifying what and where the problems are.
Total page views or unique visitors are measurements of what?
Metrics
What three types of questions should be asked in a survey?
1) Characteristic questions
2) Behavioral questions
3) Attitudinal questions
Metrics, Customer Feedback, surveys, usability tests are all what?
Quantitative Methods
Clues about how a product should be used is called:
Affordances
The relationship between controls and the results of those controls is referred to as:
Mapping
When actions are restricted to reduce errors it is called:
Constraints
The inspection of an entire system to see whether or not it complies with design principles is called:
Heuristic Evaluation
A step by step evaluation of selected typical tasks within a system by a user is called:
Cognitive Walkthrough
A walkthrough in a group is called a:
Pluralistic Walkthrough
The guidelines and principles that are put in place to help us uphold values are known as:
Ethics
Ethics help us in three areas of user design:
Decision Making
Values
Responsibility
What is the formula for calculating goals in user research?
importance x severity = priority
When creating a schedule for your research you should do four things:
Integrate schedules
Adapt priorities
Focus on big issues
Focus on general issues
What are the characteristics of a CONTEXTUAL INQUIRY?
Users needed: 10
Interviews in a work context
Easier to address realistic issues
What are the characteristics of the THINKING ALOUD method?
Users needed: 3 - 5
Lifecycle stage: Formative evaluation, iterative design
Benefits: Pinpoints user misconceptions, cheap
Disadvantages: Unnatural for users, hard to verbalize
What are the characteristics of the FOCUS GROUP method?
Users needed: 6-9 per group
POBA talk
Lifecycle stage: early development, feature definition, user involvement
Advantage: Spontaneous reactions, group dynamics
Disadvantage: Groupthink, Social demand characteristics
What are the characteristics of the OBSERVATION method?
Users needed: 5+
Lifecycle stage: Task and environment analysis, follow up studies
Advantage: Ecological validity, reveals real user tasks, suggests functions and features
Disadvantage: No experimenter control, intrusive, time consuming data analysis
What are the characteristics of SURVEYS?
Users needed: 30 +
Lifecycle stage: early design, follow up studies
Advantage: subjective user preferences, easy to repeat, and analyze
Disadvantage: Sample bias, time consuming, no additional probing
What are the characteristics of USER TESTING?
Users needed: 10 +
Lifecycle stage: Competitive analysis, benchmarking, final testing
Advantage: Controlled study, quantitative data, results easy to interpret and compare, replicable
Disadvantage: Low generalizability, tasks artificial and restricted, time intensive
What are the characteristics of a DIARY/PROBING study?
Users needed: Clusters of 5 (families)
Lifecycle stage: environment analysis, early design stages
Advantage: In context, over time, personalized, rich design inspiration
Disadvantage: Little control, response bias, hard to analyze
When do you need to do an interview?
- When there is a need to attain highly personalized data
- There are opportunities required for probing
- A good return rate is important
Respondents are not fluent in the native language of the country or have difficulties with written language
What uses subjective judgment to analyze a company’s value or prospects based on non-quantifiable information?
Qualitative Analysis
Name some forms of survey bias:
- Sampling bias
- Non-responder bias
- Timing/duration bias
- Invitation/incentive bias
- Self-selection
- Presentation bias: technologically, esthetically
- Expectation bias
What is it when people transfer their expectations from familiar objects to similar new ones?
Transfer Effects
