通过阅读诸如电子论文或学位论文（ETD）的长学术文档来处理信息需要读者的大量认知资源。而且，从常规屏幕阅读长的数字文档通常是困难的。在这项研究中，我们研究了使用大型高分辨率显示器（LHRD）呈现长文档的效果;我们专注于内容的理解和用户体验。比较了三种不同的ETD呈现方法：（1）在50个平铺液晶显示器阵列上呈现ETD的页面，按章节组织。用户在大屏幕上阅读、移动和重新组织ETD的页面和部分。(2)通过将其呈现到纸上来提供ETD。用户可以自由地在大办公桌表面重新组织文档。(3)在单个LCD显示器上显示ETD。用户使用传统的鼠标和键盘界面导航页面。从计算机科学系招募了12名人机交互（HCI）领域的研究生。四名参与者被随机分配到每种演示方法。为了激励参与者，一个64页的人机交互硕士论文，其中包含多个数字，在其摘要和附录部分被删除后使用。这些任务与内容的理解有关：写一个摘要，并回答一系列需要浏览页面的问题。测量完成时间和准确度。使用问卷调查和半结构化访谈收集用户体验。这些指标表明用户对文件的满意程度和理解程度。为了详细分析LHRD的各种特征（例如，高分辨率、宽视野和物理导航）影响用户对文档的主观理解，所有会议都进行了视频和音频记录。设计的影响进行了讨论的基础上，从这项研究的结果。
Processing information by reading a long scholarly document such as an electronic thesis or dissertation (ETD) requires a massive amount of a reader’s cognitive resources. Also, reading a long digital document from conventional screens often is difficult. In this study, we investigated the effects of presenting a long document with large high-resolution displays (LHRDs); we focused on comprehension of the content and on user experience. Three different methods of ETD presentations were compared: (1) Presenting an ETD’s pages on an array of 50 tiled LCD monitors, organized by chapters. Users read, move, and reorganize pages and sections of the ETD on the large display. (2) Providing an ETD by rendering it to paper. Users are free to reorganize the document on the surface of a large desk. (3) Presenting an ETD on a single LCD monitor. Users navigate the pages using a traditional mouse-and-keyboard interface. Twelve graduate students in the Human-Computer Interaction (HCI) area from the Computer Science Department were recruited. Four participants were randomly assigned to each presentation method. To motivate participants, a 64-page HCI Master’s thesis, which contained multiple figures, was used after its abstract and appendix sections were removed. The tasks were related to comprehension of the content: to write a summary, and to answer a list of questions that require navigating pages. Completion time and accuracy were measured. User experiences were collected using a questionnaire and a semi-structured interview. These were indicative of the user’s satisfaction and level of comprehension of the document. To allow detailed analysis of how various characteristics of LHRD (e.g., highresolution, wide field of view, and physical navigation) affect users’ subjective understanding of the document, all the sessions were video and audio-recorded. Design implications were discussed based on findings from this study.
