為了滿足人類運輸及移動的需求，應用於汽車的導航系統產品不斷的推陳出新。目前車用導航系統的路線指引是以LCD的視覺以及作為餘備資訊的語音聽覺顯示的方式為主，在駕駛行進當中即時顯示轉向指示。然而車用導航系統都不可避免會造成駕駛者轉移視線而未注意前方路況、視線遮蔽以及視覺疲勞，帶來安全上的隱憂。因此，本研究欲探討汽車導航路線指引，如何以符合人因的方式呈現，並據此設計了以類比式LED點矩陣所提示的導航介面。實驗共分為兩個階段，第一階段實驗以LED點矩陣介面的三個視閱角度：0°、30°與60°作為自變項，進行對路線的視認性研究，並決定出最佳視閱角度為60° 的LED導航介面；第二階段藉由駕駛模擬器，讓受測者進行導航工作與周遭視覺偵測工作，最後進行受測者的主觀評量。以兩種介面：數位式LCD、適閱角度60° 的類比式LED點矩陣與二種道路類型：二選一的標準型路口和多選一的複合型路口之2 × 2的混因子作為自變項，應變項為導航工作正確率、PDT的反應時間和命中率，以及主觀評量。結果顯示在導航轉向正確率的表現以及PDT的反應時間上，LED較LCD佳；在主觀評量方面，LED整體的評估優於LCD。因此，未來可應用類比式LED點矩陣於車用導航路線指引的介面，有效提昇駕駛的安全性與效率。

In-vehicle navigation products thrive constantly for fulfilling people’s need in transportation and movement. Currently, route guidance for in-vehicle navigation is represented with LCD’s visual display and auditory display as redundant one for representing turn signal while driving. Nevertheless, in-vehicle navigation system inevitably results in drivers’ obstructed vision and visual fatigue, which brings safety concern. Therefore, this study explores route guidance for in-vehicle navigation for ergonomics-applied display, and accordingly designs a navigation display with analogical LED matrix. Experiment is divided into two parts. The first experiment takes LED matrix display at three viewing angles：0°、30°and 60° as independent variables to find the effects on recognition of routes, and accordingly determines 60° as the best viewing angle for LED navigation display；the second experiment proceeds with a driving simulator, having subjects carry out navigation task, PDT（Peripheral Detection Test）task and subjective evaluation in the end. Two interfaces：digital LCD and analogical LED matrix at viewing angle 60° by two intersection types：Standard intersection and compound intersection represent independent variables, with avigation correction rate, PDT’s reaction time and hit rate and subjective evaluation. Results turn out that LED is better than LCD on both navigation correction rate and PDT’s reaction time； Generally, LED performs better than LCD on subjective evaluation. Therefore, the prospect of LED matrix as route guidance display for in-vehicle navigation is available for elevating driving safety and efficiency and further accomplishing mobile life.
