GPS 車用導航系統，隨著電子資訊技術的發展，已不再是純粹的導航用途，它 更可結合其他相關的通訊、資訊、娛樂等功能，提供使用者更多的訊息互動。車用 導航系統之功能越來越多樣化，但卻不一定為使用者所需，過多的附加功能與資訊 顯示，反可能造成駕駛者在使用GPS 導航裝置的過程中，增加心理壓力負荷。因此， GPS 車用導航系統在人機互動介面的發展上，應遵循使用者的認知行為，以最容易 理解的方式，來進行設計與開發。 本計畫主要針對GPS 的人機互動過程中，分析各資訊傳遞關鍵因子對使用績效 的影響程度，並以市面上車用導航系統，作資料搜集與調查，透過GPS 導航系統圖 形介面、選單分層與電子地圖資訊顯示模式等三個階段的最佳化評估與分析，重新 規畫建立一個符合使用者需求的GPS 導航系統，並以虛擬實境模擬駕駛實驗，來評 估系統操作之績效與改善的效益。 預期本計畫之執行，將獲得GPS 導航系統之圖形介面構成因子與使用者認知之 關係性，及GPS 導航系統之功能項目選單分層結構，對使用者操作資訊接收績效與 心理負擔之影響。建構之GPS 導航系統電子資訊顯示模式，對使用者於駕駛過程 中，認知之GPS 系統使用介面與資訊傳遞模式，提供參考之依據，使人機互動模式 走向更人性化與更智慧化的發展。 Development of a Human-Computer Interaction Operating Model for In-Vehicle Navigation Systems The progress of computer and information technology development has made the function of in-vehicle navigation systems not just for navigation. It could be combined with other communicative, informative and entertaining functions to offer users more interactive information. However, the in-vehicle navigation systems may not reach users’ requirements although nowadays they offer more and more various functions. In fact, too many additional functions and information will increase users’ burden. Therefore, the human-computer interaction interface in the in-vehicle navigation systems should be designed and developed based on users’ cognitivebehavior to present the content with the most comprehensible way. The objectives of this proposed research project is to analyze the influence of operation performance caused by key factors that transmit information in the process of human-computer interaction when using an in-vehicle navigation system. Followed three stages of assessment and analysis (Graphical User Interface, hierarchical menu, and the information display mode of electronic guide map), the in-vehicle navigation system will be re-constructed based on the data collection and analysis of marketed in-vehicle navigation systems. In this research, the concept of virtual reality (VR) will be applied to develop a simulation experiment of vehicle driving to assess the operation performance and improvement of the system. It is expected that through the implement of this research, the following information can be obtained: (1) the connection between the factors of graphical user interface in the in-vehicle navigation system and user awareness, (2) the influence degree of the structure of the hierarchical menu on operation performance, and (3) the influence of electronic information display mode on receiving information and the degree of users’ burden. In addition, this research will provide referencing information and research process with designers to help establish users’ awareness on the graphical user interface and the information transmission mode of in-vehicle navigation systems to make human-computer interaction be more humanized and intelligent.
