    摘要: 圖書館是高等教育中最珍貴的要素,圖書館網站則在數位化時代中提供使用者資訊的分享並減低數位落差,而網站的介面則必須具備直覺性與易於使用的特性,讓使用者能夠有效率的利用網站上的資源與服務。本研究之目的為透過使用者測試與啟發式評鑑了解淡江大學覺生紀念圖書館網站之網站使用效能是否符合使用者介面使用效能原則,並彙整出使用者任務分析結果與評鑑專家所提出之改進建議。研究對象分為使用者與評鑑專家,從淡江大學淡水校區抽樣7名大一學生作為受測者,啟發式評鑑專家為3位介面設計與使用效能領域專家。
    本研究結果歸納出以下3點:一、9項淡江大學覺生紀念圖書館網站的介面設計滿意度中超過3.5的只有版面配置、色彩搭配與操作設計3項,顯示受測者對於網站介面設計滿意度偏低;二、根據Nielsen(1993)所提出的易於學習、使用效率、容易記憶、錯誤率與滿意度5項使用效能屬性效標檢視網站,結果顯示網站無法滿足各項要素,網站設計不符合使用者之想法與需求;三、根據兩階段的使用效能測試結果,本研究以研究者所提出的介面設計原則以及Nielsen(1993)所提出的5項使用效能屬性效標對淡江大學覺生紀念圖書館網站提出介面設計與使用效能修正建議。
    根據研究結果,本研究提出了兩點建議。第一點為提昇網站使用效能之建議,分別為:一、以使用者角度思考,掌握使用效能原則與人機介面設計要素,以及二、將圖書館網站視為一個媒體而非工具。第二點為未來研究之建議,可分為啟發式評鑑與使用者測試兩部份:啟發式評鑑之建議為:一、啟發式檢核表可採五點量表方式評分;二、實際訪談進行更深入的探討。使用者測試之建議為:一、增加受測者樣本與異質性;二、進行反覆的測試與修改;三、提供受測者測試同意表;四、使用FireFox瀏覽器開啟受測網站;以及五、準備預備電腦。
    Library is the most valuable element in higher education. In the digital era, for the library website to provide information sharing and to reduce digital divide, the interface must have the features of intuition and user-friendliness to facilitate efficiency of use of the resources and services. The purpose of this study was to investigate the usability of Tamkang University Chueh-Sheng Memorial Library website through user testing and heuristic evaluation to ascertain whether the design conform to usability principles. Additionally, this study also aimed to report the usability testing results. The participants in this study were 7 users and 3 experts. The users were college freshmen from Tamkang University Tamsui campus, while the experts were from the field of interface design and usability.
    The results of this study were as follows: 1. Only 3 out of 9 of the satisfaction ratings were higher than 3.5, namely page layout, color coordination, and operational design, indicating that users were unsatisfied with the interface design. 2. The web design did not conform to Nielsen’s (1993) definition components of usability, which are learnability, efficiency, memorability, errors, and satisfaction. 3. In terms of interface design and usability, this study provided suggestions for revision according to interface design principles compiled by the researcher and 5 definition components of usability proposed by Nielsen (1993).
    Based on the findings of this study, the following conclusions were made.First, to enhance usability of websites, designers should grasp elements of usability and human-computer interaction and think from users’ perspectives. In addition, library websites should be viewed as media rather than tools. Second, with regard to future research, use 5-point rating scale for heuristic evaluation. Face-to-face interviews should also be carried out to gather further conceptions. Third, as far as user testing is concerned, future studies can increase sample size and user heterogeneity, conduct iterative testing and revision, provide consent form to users, use FireFox browser to open the testing website, and prepare additional computers in case of technical difficulties.
