抬頭顯示器之駕駛資訊介面設計研究
A Study of the Driving Information Interface on Head-up Display
摘要
近年來由於車輛產業的發展以及駕駛者的需求，市面上出現一種商品「HUD 抬頭顯示器」作用是要讓駕駛者更輕易地掌握車上資訊。本研究主要目的在於探討HUD 抬頭顯示器的駕駛資訊及組成元素對於駕駛者的影響。本研究分別進行兩段實驗。 首先在先期研究中以問卷調查方式，了解目前大部分的人對於車用 HUD 的使用者的感覺與認知、HUD 的背景透明度和目標字顏色與可視性的關係。 先期研究結果歸納如下： (1) 發現聽過抬頭顯示器的百分比(62.5%)高於使用過抬頭顯示器的人數百分比(34.7%)。另外，會使用抬頭顯示器的主要原因，為買車時就已經附在車上(60%)。 (2) 使用者的感覺與認知問卷調查顯示，大部份受訪者對於HUD 結合車載資訊的科技有著正面態度和相當的使用意願。 (3) 用過 HUD 比沒用過HUD 的使用者對於HUD 結合車載資訊的科技有更高的正面評價。 (4) 在車載資訊調查中，發現與車速有關的資訊，時速與限速分別名列前茅。 (5) 背景透光率、目標字顏色兩者與可視性的關係研究中發現，介面資訊與背景對比性越高的對於介面資訊可視度的幫助越好。接著透過先期研究、文獻探討，整理出下述的實驗變數，時速資訊（綠、橙、白、 藍）、不同表達數量資訊的方式（圓形、水平、數位、圓形+數位）、不同圖示的限速（實心圖、輪廓圖）、不同比率的透光率背景（高透光率、低透光率）。接著以直交表L16設計出16 組介面圖示，來進行駕駛模擬實驗與QUIS使用者滿意度問卷調查。 (6) 結果顯示，以速限標誌為例的靜態警告資訊圖示是用輪廓圖的表示方式為佳；以時速為例的表達數量資訊圖示，是以圓形圖示(相似於車上顯示時速的形式)的方式為佳。在顏色方面，以資訊顏色白色，圖地明度差較大的為佳。 最後，因應汽車工業的發展，所以汽車的介面也越來越科技與多元化，但在眾多商品中，唯有考量人們的需求與能力，這樣的產品才會被人們接受與使用，商品也才會有價值與存在的意義。

“Head-Up Display (HUD)” is a product that appeared in the market in recent years as a result of the automobile industry’s development and drivers’ requirements. Its purpose is to let drivers more easily access information on their vehicles. The purpose of this study is to explore the effects of driving information and elements of HUD on drivers. The experiment of this study consists of two stages. For the first stage, a questionnaire survey is conducted in the preliminary study to understand the general opinion of the perception and cognition of HUD users, as well as the relationship of background transparency and text color with visibility. Results of the preliminary study are as follows: (1) The percentage of people that heard of HUD (62.5%) was higher than the percentage of people that used HUD (34.7%). The main reason that people used HUD was because it was already in the car when they bought it (60%). (2) The questionnaire on users’ perception and cognition indicates that most subjects held a positive attitude towards the integration of HUD with vehicle information, and that they were very willing to use the technology. (3) HUD users have higher opinions of the technology integrating HUD with vehicle information compared with those who haven’t used HUD before. (4) In the survey on vehicle information, car speed related information, e.g. carspeed and speed limit, ranked at the top. (5) In the study on the relationship between background transparency and text color with visibility, higher contrast between interface information and background increases the visibility of interface information. Next, experiment variables found in the preliminary study and literature review, e.g.speed information (green, orange, blue, and white), different quantitative displays (round,level, digital, and round + digital), and different figures of speed limit (solid, outline),were used in an orthogonal array L16 to design 16 interfaces, which were used for driving simulations and the questionnaire for user interface satisfaction (QUIS). Results show that static warning signs, e.g. speed limit signs, are best displayed as outlines; round figures(similar to the speedometer) are better for displaying quantities, e.g. car speed. In terms of color, it is better for information to be displayed in white with higher brightness. Automobile interfaces are becoming more and more high-tech and diverse as a result of the automobile industry’s development. However, among the multitudes of products in the market, only those that give consideration to people’s needs and abilities will be accepted and used, and only then will products have value and meaning for existence.
