Usability test

整合查詢系統以單一介面檢索多種異質資料庫，近年來已受到圖書館重視。本研究以臺灣大學圖書館安裝之MUSE整合查詢系統為例，以觀察法及訪談法蒐集使用者對MUSE 整合查詢系統之意見，徵集10位分布於人文、社會、自然科學、生物醫學、工程技術領域的臺灣大學研究生為受測者，給予四項指定之查詢任務，並於過程中觀察記錄受測者與系統互動情形。測試結束後進行結構式訪談，訪談內容包括對系統好用性之看法、建議及滿意程度，並將結果歸類至效率、效能、容易學習程度、吸引性及錯誤容忍程度五個面向，由使用者角度了解系統之好用性，供未來系統修改之參考。
彙整觀察及訪談的結果，本研究依據好用性的五個面向加以闡述結論，並根據結論針對MUSE電子資源整合查詢系統提出四點建議：一、改善資訊呈現方式；二、新增或修改系統功能；三、增加系統能提供之協助；四、修改難懂之術語。

Metasearch systems perform simultaneous searches across heterogeneous electronic resources through a single entry. In order to serve users, more and more libraries install metasearch systems to integrate their resources. This study aims to investigate the usability of MUSE Search, the metasearch system installed in the National Taiwan University Library, and to better understand user viewpoints toward this system. Five components of usability were analyzed: efficiency, effectiveness, learnability, engagement, and error. Observations and interviews were conducted in this study. Ten graduate students from the fields of humanities, social science, nature science, life science, and engineering science were solicited in the study. Students were requested to achieve four tasks. While they searching through MUSE Search, a researcher observed their behaviors and took notes. After the tasks were completed, students were interviewed by being asked questions concerning the usability of MUSE Search. Their comments and satisfaction levels were also collected.
The conclusions were divided into five components of usability. According to the findings of this study, suggestions concerning MUSE Search are as follows: 1. to revise improper display of information in MUSE Search. 2. To add new search functions, or revise old ones to meet user needs. 3. To improve help functions. 4. To revise terminologies which are difficult to be understood.

國內一般數位圖書館網站多是由資料供應單位與系統設計者提出，鮮少考慮使用者的角度。本文以國科會主題計畫網站「淡水河溯源」為例，說明運用多元方法進行使用者評估的實證研究，並試圖提出一個數位圖書館與博物館使用者研究的應用模式。 本研究的假設前提為真正有價值的網站是與使用者的工作生活相融合，因此必須根基於使用者現實世界的資訊需求與行為習慣。本主題網站目標之一為支援鄉土教育，而教學網站包括教與學，擁有教師與學生不同的使用者群，如何設計有價值的教學網站必須兼顧不同使用族群與不同的使用目的與任務，其根基在於深入瞭解他們日常工作生活的現實。本研究的結果在網站建置階段可協助系統及內容建置小組充實其內容並改進介面之設計。

Most digital libraries in Taiwan are designed by content providers and system designers. The purpose of this research attempts to propose a user study model for empirical investigation of web users, using a case study of Taiwan Digital Museum Dan-Shwei River as an example. This article reports the multiple methods used and the results found in this study, including the design principles and some substantial suggestions for practice.
