1.  Introduction

You will research a particular method as a topic, present that topic to the class, and producing a web-based handout summarizing that topic (including a simple worked example that illustrates how that methodology is applied).

Depending on the class size, you may be required to do the topic in groups of two rather than individually.

Your assessment on this component is worth 25% of your grade.

2.  Deliverables

See schedule for tentative dates. All students will deliver written materials (presentations / handouts) on the same date. The date of the actual presentation will be scheduled by the instructor.

  1. Summary: Write a summary of your topic selection (early in the course) verifying your choice of topic.
  2. Web-based handout: Create a web-based hand-out that will be added to the CPSC 681 student site, in the form of a tutorial that concisely summarizes the methodology and the concrete exercise. The handout should include
    • Overview of the method: what it is, how it works, and (if known) a brief history of it
    • When and where it is typically used in the development/evaluation/research cycle
    • Benefits and problems of this method
    • A simple worked-through concrete exercise, suitable for teaching, of how to apply the method (should include all material needed to do the method (instructions, materials, etc.) The best examples are almost trivial ones that illustrate the method.
    • An annotated bibliography of several key papers / resources that others can use to help them get started
    • A professional classroom presentation that introduces the methodology to the class and that has the class perform or walk through the above exercise of how the methodology is applied on a particular problem.

3.  Resources

I will be happy to point you to a key resource as a starting point once you have chosen a topic. Ask me! However, you will be expected to find and research other relevant resources on your own.

  • Readings in HCI Evaluation Methodologies has a selected set of papers on particular evaluation topics.
  • Saul's Library contains a good number of relevant books that you can sign out. This includes textbooks with good introductory chapters on evaluation methods. Browse these for ideas.
  • Digital Libraries with HCI content abound, and include many articles illustrating, discussing and applying evaluation methods.

4.  A note on plagiarism.

You must avoid plagiarism when using the above resources. Use your own words, quote selectively (with citations), and be careful to list your sources. You can selectively use a few images/examples provided by others, but you must cite them appropriately. Plagiarism - whether intentional or accidental - has severe consequences.

5.  Example topics

I will select topics from the possible topics listed below. Depending on individual interests, I may focus on some topics over others.

For complex topics, I may assign several students to consider different aspects of it. If this is done, the students are expected to coordinate with each other.


  • Interview techniques
  • Contextual interviews
  • Ethnographic interview
