選單預示性設計瀏覽成效之世代差異研究

網頁選單的呈現設計愈來愈舉足輕重，而高齡者和年輕人心智模式差異極大，對於選單呈現設計的瀏覽成效有所影響，如何設計出考量到世代間差距，容易瀏覽、辨識的網頁選單，遂成為值得探索發展的議題。預示性強調縮短設計師與使用者之間的認知差異，提供強烈的視覺線索，讓使用者能夠直覺地感知產品的特徵屬性，其概念可以幫助網頁選單設計上的脈絡和評估更加完整，因此本研究以預示性的概念來設計出網頁選單。本研究分為兩個實驗設計，第一個為針對認知預示性所設計的實驗，為2x3多因子實驗設計，比較高齡者和年輕人，在瀏覽和操作圖文混合型、純文字型以及首字放大型選單時，其瀏覽成效上有什麼差異。第二個為針對實體預示性所設計的實驗，為2x2多因子實驗設計，比較高齡者和年輕人，在瀏覽和操作平面型和立體型的選單上，其瀏覽成效上有什麼差異。研究結果發現，瀏覽操作首字放大型選單和立體型選單時，高齡者和年輕人的任務表現最佳，滿意度、預示性最佳。

Website menu design become more and more important, and considering the big differences between the elderly and the young’s mental model, which will affect how people navigate the menu interface, it is worth to find out how to develop a website menu which is easy to navigate and identify for different generations. The concept of affordance stress to shorten the cognitive differences between designer and user, by providing strong visual cues, user can intuitively perceive the product’s design attributes. This study separate into two experiment design. The first one is about the cognitive affordance, 2x3 multifactorial experimental design, aiming to compare the difference of navigation performance between the elderly and the young when they navigate and use the iconic menu, word menu and first-letter-amplified menu. The second one is about the physical affordance, 2x2 multifactorial experimental design, aiming to compare the difference of navigation performance between the elderly and the young when they navigate and use the flat menu and three-dimensional menu. The results of this study indicated that for the the elderly and the young, first-letter-amplified menu and three-dimensional menu having the best affordance, navigation performance and satisfaction.
