  4. Test Recruiting • Sent email to SI Informatics email list • Gave general information about study along with how much time it would take • Promised them a $25 Amazon gift card after their participation • We aimed for 5-7 subjects • Scheduled 7, 2 canceled so we tested 5 subjects

  5. Usability Test Tasks • 4 Tasks • 15 minutes • Client: focus on search and multimedia content+ • Try to simulate normal operations that a general user will usually do in the system

  6. Usability Test Tasks • Find two articles about nuclear power, one in favor and one opposed. Translate the second article into French and send it to your French friend (hao.hci@gmail.com). • Find 2 radio broadcasts about the 2011 earthquake and tsunami in Japan, save them to your personal favorites in the system, and then start playing one of them. • Find a magazine article about unemployment and download the article’s APA citation. • Find an article related to stem cell research from a peer reviewed journal that was published in 2005.

  7. Test Logging • Logging sheet for each task • From 2 to 4 subtasks • Completed?  Y / N • General questions • Surprised?    Y / N • Stuck?          Y / N • Confused?    Y / N • Space for comments and notes • To be filled either by pen or by computer (Word document) 

  8. Moderation & Debriefing • Introduction script • Sign consent form • Pre-test questionnaire  • Background, demographics, experience • Begin tasks • Encourage talk aloud • Post-test questionnaire • Reflect on experience • Likes, dislikes, improvements • Ask for questions • Thank and dismiss

  10. Location and Setup • 1150B/1150C at North Quad • 3-4 researchers present • Audio recording by computer

  11. Usability Test Findings and Recommendations

  12. Usability Test Findings: #1 The “Listen” appears on top of the content of every document for people with visual impairment; But it causes significant confusion for general users.

  13. Usability Test Findings: #1

  14. Usability Test Findings: #1

  15. Usability Test Recommendations: #1 Recommendation: Rename to "Read the Screen" and move to Tools section.

  16. Usability Test Findings: #2 Pro and Con Indicators Are Needed In Search Results • System is designed to give users arguments from "both sides" of an issue • Sides of articles aren't readily identifiable in search results

  17. Usability Testing Recommendation #2 • Implement short summary to let user know if articles is "Pro" or "Con" for the subject that they are searching about • "Pro" or "Con" summary could be anywhere from one sentence up to a short paragraph. • Summary text could be placed to left of search results, just make column with results in it a bit skinnier (which would be ok)

  18. Usability Testing Recommendation #2

  19. Usability Test Findings: #3 Basic Search is used often, but is not fully satisfactory.

  20. Usability Test Findings: #3 • Does not handle Google-style queries •         "stem cell research 2005"  •         "Japan tsunami audio" • Recommendation: improve search algorithm to accept more parameters (not just keyword)

  21. Usability Test Findings: #3 Recommendation: add filtering options from advanced search into results page for basic search

  22. Finding 4: Options in Advanced Search Are Ambiguous Usability Test Findings: #4 • Users were confused about what "Content Level" means • Because they don't know what content level means, they can't make sense of the options that they can select • It frustrated users when they weren't able to tailor the advanced search options clearly

  23. Usability Test Recommendations: #4 • Cengage should name "Content Level" something that is more descriptive of what the feature actually filters • Cengage could add a help section that describes all of the features that are offered in the Advanced Search
