本研究分為三個階段;前期透過網路問卷,調查目前市售汽車音響主機的使用現況,第二階段再由受測者自行配置產生一台新式的汽車音響主機介面與另兩台由市售汽車音響主機中所挑選出之機型,在第三階段一起進行實驗,歸納結果如下: (1) 在前期透過網路問卷,調查目前市售汽車音響主機的使用現況,發現2 DIN的介面在整體的分析比較上優於1 DIN的介面。 (2) 在後期實驗中顯示,「新式樣主機」在整體的操作時間是最短的與操作錯誤次數是最少的。 (3) 在後期實驗後的主觀問卷調查中顯示,「新式樣主機」在「可以很快的從介面上找到你要執行的功能」、「可以很快的找到你想要操作的按鍵」、「操作介面沒有太過複雜,沒有過度設計」、「不需要透過旁人的協助才能使用這個操作介面」這幾項問題中都顯示優於目前實驗的另兩台汽車音響主機。
The study is in 3 stages. In the first one, survey is made to find out current use of car audio through questionnaires. Testees assemble one new car audio and select 2 models in the market in the 2nd stage. Experiment is made in the 3rd stage. Findings are: (1) In the findings from questionnaires, the 2 DIN interface is better than 1 DIN interface in overall analysis. (2) In the experiment, new style unit has shortest operation time with least operation errors. (3) In subjective questionnaires in experiment, new style unit outperforms the other 2 units in “quickly locating desired features on interface,” “buttons quickly located,” “operation interface too complicated without over design” and “free from help of other people to opiate the interface.”
