摘要: 放聲思考法最常採用同步與事後回溯兩種方式來收集參與者的口述資料,而蒐集的方式依研究取徑的差異,分成了認知歷程的探究以及使用性問題發現兩種目的。本研究以後設認知作為理論依據來建立編碼簿原則,目的是為了發現視覺化軟體的使用性問題,採用放聲思考法並佐以眼動軌跡來蒐集資料,最後提供有效發現使用性問題的方法流程。 實驗設計採用了2(同步放聲思考法)X 2(回溯放聲思考法)之組間設計,檢視方法的組合在任務表現、滿意度和心智負荷上的差異,口述資料以內容分析法來進行解讀,強化資料的可靠性。 研究結果發現,同步搭配回溯放聲思考法最能產生關於使用性問題的洞察,而同步放聲思考法並不會造成較高的心理負荷以及較高的滿意度,因此兩種方法的搭配更適合用來產生口述資料。
Concurrent and Retrospective Think Aloud are two different ways to collect the utterance data. According to the purpose of the study, Think Aloud can be used to explore the cognition process or finding the usability problems. The purpose of this study is to establish a effectively way to discover the usability of visualization software, it use metacognition as the theoretical foundation and use eye tracking to support Think Aloud to collect utterance data. The Design of the experiment is 2(Concurrent Think Aloud) x 2(Retrospective Think Aloud) between task,the purpose is to review the performance, satisfaction and mental workload throw the experiment, and the utterance data will be analyzed by content analysis, to strengthen the utterance’s reliability. The results of the study found that the combination of Concurrent and Retrospective Think Aloud produce the most useful insight of the usability problems of visualization software. While the Concurrent Think Aloud doesn’t cause higher mental workload and satisfaction as expected, which made the combination is suitable for making reliable utterance data.
