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."
