摘要

本研究應用可用性工程的啟發式評估，由專家評估社群網站介面，發掘可用性問題。同時亦探討可用性專家的差異對網站介面啟發式評估的影響，以及採取評估時最有效的經驗法則。六位專家分別進行評估後發現之問題包括超連結之意義不清楚、缺乏狀態之回饋訊息、及特殊術語無說明等，結果發現兼具可用性工程與虛擬社群網站專長之專家的評估表現較佳。此次評估同時也歸納出三組可用性原則：網站可用性基本原則、虛擬社群網站可用性原則、及網站可用性一般原則。本研究促使受測網站進一步廣泛應用可用性工程於網站介面設計，建立可用性工程生命週期以創造良好的使用品質。

Six usability specialists' evaluated the degree of usability for a virtual community Web site based on provided heuristics. Usability problems such as unclear meaning of hyperlinks, lack feedback for the status, no help for special terms were found. Three groups of usability principles are concluded: basic principles for the web interface, principles for virtual community site or web sites with complex information architecture, and supplementary principles for the web interface. The usability specialist with the expertise of both usability engineering and virtual community Web sites performed the best. The results help the Web site utilizing usability engineering, and developing the usability engineering lifecycle for the Web development.
