The user later cited that part of his source of difficulty was that the "May appear in sentences" label was cut off (displaying only "May appear") because the user's browser window was not maximized, and was at the time smaller than the minimum size we had designed for. However, the larger usability issue in this case was that the "check all" button's location did not make it discoverable, or that its label did not carry sufficient information scent.
Task 23
The user first tried pressing Ctrl-F to search for the word using the browser's built-in search. In our case, however, because we had implemented the site using Silverlight not HTML, the browser can't search the page. After noticing that he wasn't getting when searching via the browser's built-in search, he quickly switched to the search box. The user didn't have any issues locating the search box or using it. After typing in the pinyin for the word, he found the word in the search results, but initially he checked the "May appear in words" checkbox, and didn't click the "make study focus" button. Only after fetching a few sentences and noticing that the desired word was not present did he focus his attention back to the left sidebar, and clicked the "make" study focus button. He clearly noticed the change this time, as he hovered his mouse around the (now highlighted in green) combobox displaying the word in the "study focus" section and faintly mumbled "ah that's it". He then pressed the "fetch next sentence" button to fetch the sentence, as expected.
Task 4
The user clicked on the word in the sentence to display its pronunciation and translation. He clicked the "make this word the study focus" as expected to make it the study focus, and then pressed the "fetch next sentence" button to fetch the next sentence.
Task 5
The user typed the pinyin in the search box to locate the word, and unchecked the "May appear in sentences" button. He then pressed the fetch next sentence button a few times to verify that the word indeed didn't show up to convince himself that he had actually accomplished the task.
Task 6
The user had no difficulty locating the close button for the button .Task 3and clicking it.
Task 7
Immediately after accomplishing the previous task and before the user was shown this task, the user switched to the Closed Sentences tab and pressed the "Remove sentence" button repeatedly until all the sentences were removed. Thus, because there were no sentences to restore, the facilitator asked the user to first fetch a new sentence and redo the previous task before proceeding. After fetching the new sentence and clicking the Close button, the user switched to the Closed Sentences tab, and pressed the Restore Sentence button. He then switched back to the Currently Reading tab, saw the sentence he had just restored, and repeated the process of closing it and restoring it from the Closed Sentences tab to verify that that its behavior indeed matched what his mental model.
Task 8
The user went to the Study Focus sidebar, clicked the combo-box, and selected selected the word in the drop-down menu as expected.
