  1. Welcome TC518: User-centered Design

  2. Mapping out Week 1 • Introductions • Tell me about yourself • Go over syllabus • Finding potential project teammates… • Introduction to User-centered design and usability • Lecture • Two activities • Revisit syllabus – focus on readings • Project • Overview of activities • Group formation and project selection

  3. General Name (and preferred way to address you) Best way to contact you (e.g., email, phone, etc.) Place of employment Domains of interest (e.g., medicine, e-commerce, etc.) Going Deeper Self-characterization: Indicate your level of agreement with the following statements by recording low, medium, or high for each: I consider myself a designer I consider myself adept at incorporating user considerations into my work Evaluation criteria: What criteria you would use to evaluate a) a hair dryer, b) a website Design process: Write down the sequence of five or so major steps one should go through in developing and evaluating a new computer system for end users. Techniques: What techniques do you use (have you used) to focus on users in your work? Tell me about yourself Please record the following information on an index card:

  4. Getting a sense of the class… Already are designers… Adept at prioritizing user issues…

  5. Syllabus – Learning Objectives+ • Following the course, students may need to • Do user-centered design activities • “Sell” user-centered design activities • Plan user-centered design activities (and make choices) • Continue to educate themselves • By the end of the course, students will be able to: • Critically discuss the concept & complexities of UCD • Identify and explain a variety of factors motivating/enabling UCD • Plan and execute activities that collectively instantiate a UCD process • Identify areas of scholarship useful in design to address user needs • Class elements • Project (70%) • Readings and discussion (10%) • Final exam (20%)

  6. Syllabus – Detailed schedule

  7. Syllabus - Class Structure Week 1 Week 2 Week 3 • HW: • Readings • Online Discussion • Project Work • HW: • Readings • Online Discussion • Project Work Share results from project exercise 1 (topic B) Share results from project exercise 2 (topic C) Discuss New Concepts via Readings (topic A/B) Discuss New Concepts via Readings (topic C) Discuss New Concepts via Readings (topic D) Discuss project exercise 1 (topic B) Discuss project exercise 2 (topic C) Discuss project exercise 3 (topic D)

  8. Syllabus – Project (70%) • Description: • Follow a user-centered design process to explore the redesign of a product/process of your choosing. • Examples: Students may redesign • Blood pressure cuff in local drugstore • Informational website for engineering educators • Check-out process for Internet retailer • Instructions/documentation for photo processing software • Educational toy designed for 5 year old • Student Responsibilities • Project exercises (7, weekly homework, collectively 20% of grade) • Project deliverables (2, significant milestones, each 25 % of grade) • Review/advisory board participation

  9. Syllabus - Readings & discussion (10%)

  10. Syllabus – Weekly schedule

  11. Syllabus – Course Design Principles Assumptions • Learning involves construction of knowledge • Students are diverse, and have knowledge to offer Principles • Provide varied ways for students to learn & demonstrate knowledge • Ensure students have opportunity to learn from each other • Manage participant burden Elements • Practice user-centered design activities • Reflect on user-centered design activities through discussions • Learn from perspectives of others • Various interactions w/ readings (summarize, discuss, synthesize) • …

  12. Activity 1: Let’s move around… • Your task: • Identify one or more domains that interest you • Find/meet other students who share domain interests • Talk about • Your motivations for taking this class and • Nature of your interest in the specific domain. • Motivation for this activity: • Projects involve teams • Teams organized around domains • Project easier if teams have prior domain knowledge • Team formation (project selection) by end of Thurs

  13. Activity 2a – Difficult Products • Individually: Think about some product/ process that you have found to be difficult: • What was the nature of the difficulty and the consequences? • What do you think contributes to (causes) the difficulty? • Group: Share your experiences.

  14. User-centered design is what you do to achieve usable systems Usability is the typical way a user-centered design product is evaluated We will talk about usability then about user-centered design

  15. Defining Usability • “The extent to which a product can be used by specified users to achieve specified goals in a specified context of use with effectiveness, efficiency and satisfaction” (ISO 9241-11) • “The measure of the quality of the user experience when interacting with something – whether a web site, a traditional software application, or any other device the user can operate in some way or another” (Nielsen) • “Usability means that the people who use the product can do so quickly and easily to accomplish their own tasks” (Dumas and Redish)

  16. Defining Usability (Barnum, p. 6)

  17. Benefits of a usable system (Maquire, p. 589)

  18. Usability and User Experience Usability stems from entire user experience: • Device Interface – Visual, tactile, input devices… • Support manuals • Packaging • Computer system • Workspace Each of these aspects of a product/process can be redesigned to enhance usability…

  19. Activity 2b: Difficult Products (cont.) Building on your discussion of a difficulty and contributing factors, discuss the following in your group: • Is the difficulty a usability issue? If so, what aspects of usability are relevant? If not, are there other difficulties that are usability related in nature? • What might be included as part of a “user’s experience” with the product? How does the answer to this question affect your diagnosis of contributing factors? • What might be the benefits of a more usable version of this product? • Also (time permitting)… What did the designers fail to take into account, such that the original design was difficult? Why might the considerations not have been taken into account?
