博士 === 逢甲大學 === 工業工程與系統管理學研究所 === 100 === As display technology has matured, not only have display sizes become larger, but also prototype curved displays have been developed. Large, curved displays may be used for personal workstations that combine work and entertainment in the near future. However, interactions with large, curved displays will have big differences from interactions with normal, flat displays. In this research, three topics are discussed. First, user eye and head movements are measured during interactions with large, curved displays. The results show that the eye and head movements are greater in number and in extent with large displays than with typical displays. Further, the curved display causes more head movement than a flat display causes. The users have significantly less head lagging time on the large, curved display (p<0.05); this shows that the large, curved display introduces more physical fatigue to users. In the second part of the study, user arrangements for windows with different task attributions are explored. The results show that users tend to locate the window with more complicated tasks near the center of the display, and they arrange windows providing simple information to one side of the display. Tasks that involve long interaction times tend to be repositioned near the center of the display. In the third part of the study, the design elements for Notification Information are explored; the ability of using peripheral vision to capture the information is discussed. The results show that the larger the notification area is, the easier users can detect the notification. On the other hand, the presentation location for the Notification Information has significant effects on users’ detection. The larger the eccentricity of the Notification Information is, the larger JND Phase Shift is. However, the location effect decreases when the presentation area becomes larger. When users try to discriminate between different notifications, the more stimuli the users have, the worse their discrimination is. Notifications that have multi-dimensional designs provide better performance than single-dimensional notifications. This result is consistent with our expectation. With the improvement of the display technology, personal workstation displays will tend to be confined by fewer limits. Users will take advantage of many ways to get information from large displays. This research focuses on basic measurement and several applications that can be developed on large, curved displays. The results not only reveal the benefits provided by the display, but also human behaviors, changes to interaction styles, and some restrictions to interactions with such displays. These are expected to provide guidelines for future designs of personal workstation displays.
