Consider the following task: invitees to a meeting need to be able to quickly add other potential attendees to the meeting’s invite list, potentially including a message about why they were invited. Digital calendars need to provide mechanisms to support this task. Analyze this task from each of three models of the user: processor, predictor, and participant. First, analyze this task thinking of the user as a processor. Propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Remember, you should focus on the goal of the design, not the goal of the user. Then, analyze this task thinking of the user as a predictor. Again, propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Then, analyze this task thinking of the user as a participant. Again, propose what the goal of the design should be given this view, and then propose how you might measure whether that goal was achieved. Finally, discuss a way in which two different models of the user might suggest different design decisions. Identify one way the designs informed by the two models might differ, and propose how you would decide which design to go with. Note that there is no one single right answer to this question. There are many compatible goals and measurements you might propose. Our objective with this question is to evaluate whether the goals and measurements you propose are truly emblematic of the model to which you attach them. Focus your answer on efficiently demonstrating you understand the three models.

Chapter 4 of I. Scott MacKenzie’s Human-Computer Interaction: An Empirical Research Perspective and “Survey Research in HCI” by Hendrik Müller, Aaron Sedley, and Elizabeth Ferrall-Nunge together provide a strong overview of the use of surveys in human-computer interaction research. Imagine you are running a study where you want to evaluate users of digital home security systems (e.g. SimpliSafe, ADT, Vivint, Brinks, Cove, etc.) about their use habits. Because you want to evaluate a variety of tools, you opt for survey research. First, describe some data you will seek to gather from this survey. The data you gather must include at least one example each of nominal, ordinal, interval, ratio, and qualitative data. Make sure to identify which data are of each type. Then, describe who the study’s population, sampling frame, sample, and respondents would be, and explain how each of those categories is derived from the previous one. Finally, describe at least two reasons your study’s findings might not be generalizable, either due to issues of validity or due to potential biases. Remember, our goal is to assess your understanding of the relevant course concepts, not compare your answer to a pre-established list of correct answers. You may articulate your assumptions or add additional details necessary to allow you to demonstrate you understanding.

Consider the following situation: you are designing a new digital tool for employees to use to evaluate their superiors as part of quarterly review. First, analyze this situation from the perspective of the stakeholders involved in this design. Identify at least one primary stakeholder, two secondary stakeholders, and one tertiary stakeholder. For each of these four (or more) stakeholders, describe why you define them as a primary, secondary, or tertiary stakeholder. Second, for your tertiary stakeholder, describe how keeping that tertiary stakeholder in mind might alter the design compared with ignoring that tertiary stakeholder. Third, describe one instance where the interests of two stakeholders might be in conflict. Explain why, and briefly describe how different designs focusing on each of the two stakeholders’ interests might differ. Note that there is no single right answer we are looking for on this question: we are not grading based on whether you name the same stakeholders we have in mind. Rather, we are looking for you to demonstrate your understanding of the different types of stakeholders, as well as the value of considering then in your design process. You may add details or articulate your assumptions in your answer as necessary to allow you to demonstrate your understanding.
