1. SWE 4324 UCD - WEB A FINAL VERSION Evaluation of a feature Note about Webs – Webs are the interactive class you must participate for a satisfactory understanding of User Centered Design (UCD). The Webs have a reading component, thinking component, and creating component. They are an investment of about 3-5 hours of effort with double hours of satisfaction because you will learn & understand the material in the execution of the webs.

2. Web A – to be done between the end of class and Sunday midnight. (Due in D2L) 0. Read Ch. 1 1. Explain what our authors mean with “computers pervade our life”. 2. Diagram your daily interaction with your microwave, your coffee machine, or your alarm clock. 3. What part of #1 above was ubiquitous. 4. Give you effectiveness, efficiency, and satisfaction for your daily interaction in #1 above. 5. Consider a frustrating and dissatisfactory experience with any system you have had recently. Give the following for this experience: a) Your task goal: b) The first confusion: c) The interface at that time: d) Your understanding of the system at the moments of confusion:

3. Web A continues… 6. Suppose your were tasked with re-design of the control panels for the Three Mile Island nuclear power plant. Propose four specific design goals after you study Box 1.4 on page 10 of Ch. 1 Section 3.3 7. Exercise 1.3 on page 18: Think about your last programming team project. Give the list of people involved in the project with regards to their role in the project. (No last names – instead the roles of the persons)

4. Web A continues with the start of your usability experience.. Read Box 4.3 on page 68 Read Exercise 1.2 on page 13 8. Think about an application with a particular feature you found very confusing to use during your initial experiences and still find dissatisfying a) Document the problem with the feature and your confusion. b) Create a step by step walk-through of the application’s feature use with individual screen shots like figure 1-7 on page 14 and Box 4.3 on page 68. c) User’s Task Narrative - Create a narrative for a user to experience the feature. (This would serve as a basis for “testing” the user experience.) Good “testing” materials give clear user motivation for them to need to use the feature. Do not tell them what to do step-by-step. This would destroy the user’s choice. Instead give them the setting of what they are have been doing and then a goal that motivates them to use the feature.

5. Web A continues…. d) Pre ? = Create a Pre Questionnaire for your user in which you ask them the important personal, task, and environmental characteristics that might affect the usage of the feature. e) Post ? = Create a Post Questionnaire for your user to give you feedback about their experience and their thoughts about the feature. Some of your Post questions need to get Qualitative Data and some need to obtain Quantitative Data (specific numeric data).

6. Web A continues with an initial test of your materials…. f) Now act as a new user – imagine that you have not experienced the feature previously. Take some time to do your materials created in #8 d, c, and e above. Sample your materials as a new user and document what is experienced for the “new user”: Do and “log” your #d – Pre questionnaire (Pre ?) Do and “log” your #c - User’s Task Narrative Do and “log” your #e – Post Questionnaire (Post ?) Note: “log” is a documentation of the user’s actions, answers, and timing.
