Study Notes

Human Factors in Computing (CS 5140)

The course focuses on human factors in the design of computing systems.
Design thinking is a crucial concept in this field.
This iterative approach involves empathizing with users, defining the problem, ideating solutions, prototyping, and testing.

Qualitative Study

Qualitative studies do not involve numerical calculations.
Focus is on understanding the human mind, behavior, and characteristics.
Aims to obtain deep and holistic understanding of phenomena.
Data collection methods include explanations, experiences, stories, and observations.
Examples include colors, favorite destinations, names, and ethnicities.

Qualitative Data vs. Quantitative Data

Qualitative data: Not numerical, includes descriptions, experiences, names, and qualities
Quantitative data: Numerical, includes scores, weights, temperatures, shoe sizes

Qualitative Study Examples

Examples may include qualitative data such as the color of the sea, favorite destinations (e.g., Hawaii, New Zealand), names (e.g., John, Patricia), and ethnicities (e.g., American Indian, Asian).
Qualitative study examples also include exploring why certain age groups prefer Instagram over Facebook.

General Steps for Qualitative Studies

Determine objectives: Understanding user needs and functionalities
Develop focal points: Questions concentrating the study project
Identify and recruit participants: Engaging the intended audience
Determine data collection methods and design materials: Strategies and resources for gathering information, including interviews.

Design Improvement and Evaluation Parameters

Attractiveness: Overall impression of the product
Efficiency: Ease and speed of completing a task within the design
Stimulation: Feelings of excitement and motivation
Perspicuity: Ease to understand the product
Dependability: Design's predictability and reliability.

Example questions for Design Evaluation

"Which parts of the design do you think have made it attractive?"
"How would you evaluate our use of font and colour to make the design visually appealing?"
"What changes to the design would make it more attractive?" (direct involvement)

Participants Recruitment Strategy

Strategies for recruiting participants, including flyers.
Using convenience and snowball sampling methods to recruit individuals.

Interviews

Types of interviews: Structured, semi-structured, and unstructured.
Structured interviews: Predetermined questions in a specified order.
Semi-structured interviews: Combine structure with flexibility for follow-up questions.
Unstructured interviews: Flow naturally like a conversation, with general topics covering a specific subject.
Interview guidelines, including dos and don'ts, help increase research quality efficiently.

Interview Guidelines/Do's and Don'ts

Do's: Organize before beginning (equipment, scripts, designs), structure the interview time, give context of the interview, employ visuals, maintain eye contact, be respectful and attentive, provide sufficient time to think.
Debriefing: Meet after the session with the partner/team and make a log of everything collected.
Don'ts: Leading questions, closed questions (instead use open-ended questions), double-barreled questions, pre-supposing answers, excessively long questions, inappropriate jargon, unnecessary interruptions

Demographic Questions

Questions to provide contextual information on the participants.
Demographic questions should be put at the end, to avoid priming for later questions.
Carefully worded questions, and answer choices should accurately represent the information sought and must protect the participant's privacy. Offering "prefer not to answer."
