摘要

衛星導航系統的基本功能以提供路徑搜尋及導航地圖為主，另含有娛樂功能及通訊功能等增進生活使用者經驗的附加的功能。本研究主要目的為探討手持式衛星導航系統之使用者介面，聚焦於介面風格與使用者經驗之設計與評估。本研究實驗分兩階段，前期調查階段與後期設計驗證階段。前期調查階段針對目前現有不同廠牌，挑選三款手持式衛星導航為樣本進行階層架構、圖形預視性與使用性探討。根據前期調查之結果與文獻歸納準則，設計出四個不同介面風格的介面提案:包括傳統風格、滾軸式風格、滑動式風格、檔案夾式風格。後期設計驗證階段進行四（介面風格）X二（使用經驗）混合雙因子設計。受測者共邀請10位，有操作經驗者5位，無經驗者5位，接受指令執行指定項日，並操作四款不同介面風格的介面提案，並對各介面填寫QUIS使用者互動滿意度量表。研究結果顯示；（1）使用者最滿意階層架構資訊顯示簡單明瞭的設計，並可增進學習性；（2）關於介面使用性方面，因多數使用者習慣舊有點選模式，故傳統風格風格介面被多數使用者認同，而滑動式風格介面較不被大多數受測者接受；（3）使用資料夾展開收合之操作介面，並加以文字輔助說明之設計其操作績效較佳。

Hand-held GPS can be utilized for route searching and path planning, as well as serving as an audio and video device to enhance users' experience in their daily life. The purpose of this study is to investigate the user interface design of hand-held GPS, regarding the factors of different display styles and user experience. The experiments were divided into two stages-the preliminary investigation stage and design verification stage. In the first stage, the hierarchy, graphical affordance and interface usability of three commercial GPS products were analyzed. Based upon the results, four concept designs with different display styles were developed, including Traditional, Roller, Sliding, and Folder styles. In the second stage, a four (display style) by two (user experience) mixed factorial experiment was performed. Ten experienced subjects and ten inexperienced subjects were asked to complete the tasks, and then fill in the QUIS questionnaires. The results showed that users were satisfied with simple and clear information hierarchy, which also enhances its learnability. In terms of interface usability, users are accustomed to the traditional touch screen interaction style; however, the Sliding style was not accepted by many users. At last, foldable file folders designed with text supports will enable users to obtain better task performance.
