車用抬頭視覺資訊顯示對駕駛者之影響

Abstract

開車時，駕駛者的視線離開前方可說是發生車禍的重要原因之一，為了減少讓駕駛者的視線離開前方道路的次數與時間，有些車廠會在若干車輛上安裝HUD(Head Up Display)，中文稱為抬頭顯示器的配備，讓駕駛者的視線在不用離開前擋風玻璃的情況下就能得知一些諸如時速或引擎轉速等資訊，以維持行車安全。然而，駕駛者對於車用抬頭顯示器能夠呈現的資訊，其所能接受程度的極限為何，迄今尚無完整充分的資料以供參考。因此本研究之目的係針對車用資訊顯示系統所呈現的資訊型態，對於駕駛者的影響之探討。研究項目包括在顯示畫面的範圍內，對於顯示資訊的顏色、輝度、數量、尺寸與音效等五個項目，在不同情境照度下對於駕駛者情緒反應之研究。本研究利用一測試平台進行動態資訊播放，讓駕駛者觀看，同時量測腦波訊號，搭配問卷調查的方式，由觀看效果進行項目評估，並分析腦波資料，彙整數據建立資料庫，根據分析結果顯示大部分受測者符合本研究之預期，此將有助於車輛顯示系統之開發與驗證項目規畫之參考。

The main cause of traffic accidents is the line of sight of a driver deviates from the front during driving. To reduce the frequencies and times of deviation from the front roadway of the line of sight of a driver, some manufacturers equip their luxurious cars with a product called a head up display (HUD). These drivers can get some information such as speedometer and engine speed, without their lines of sight deviating from the windshield. As a result, the car is safer to drive. However, for the question of what kinds of information will be displayed by HUD and how much can be shown on a display for a driver, we cannot find enough materials for reference. Therefore, the purpose of this study is to understand how the information patterns of an automotive display system will affect a driver and also driving safety. The five variables in this study are displayed color, luminance, information quantity, screen dimension and sound effects. Within the range of the displayed screen, the driver’s reaction will be discussed under different situations of brightness. Dynamic Road conditions will be played on a screen just in front of the simulated test platform. The tester will sit in this platform and stare at the screen. The reaction in the tester’s brain will be recorded by a professional instrument called an electroencephalography (EEG), simultaneously. According to different cases and through the questionnaire survey method, the abovementioned items will be evaluated through the human visual effect. A database will then be set up from these results. The results from this experiment show most people reached the research’s expectations. It is helpful to develop an available display system of vehicles. In addition, it can also provide for the planning of verified items for automotive HUDs system in the future.
