中文摘要 | 全球資訊網已經成為許多人生活的一部份,而網站也漸漸成為公司或機構重要的窗口及服務管道。然而由於大多採用非結構性的設計方式,大部分的網站多隱含著許多人機界面的可用性問題。網站人機界面的設計不良,會讓使用者在使用網站時遭遇困難,進而導致網站設立機構流失客戶及形象受損。所以,如何使網站具有好的人機界面是目前一個重的課題。以使用者為中心是各種人機界面設計方法所強調的概念,而可用性的評估是其中最核心的項目。如個比較適用於網站的可用性評估方法進行實驗。這五種評估方法分別是:啟發式評估法、認知演練法、可用性演練法、啟發式演練法、以及使用者測試等五種。並就涵難性、正確性、可靠度、成本效益、平均問題嚴重度以及加權涵蓋性指標等準則,來分別比較各個評估方法應用於網站時的效用。 |
