摘要

全球開發中國家皆面臨人口老化的問題，隨著科技的發展迅速，電子產品推陳出新，然而針對中高齡族群所設計的消費性電子產品數量並不普遍。中高齡者隨著年齡的增長將面臨生理退化的現象產生，無論在記憶力、理解力或資訊的處理轉換終將逐漸退化，使該族群在科技產品使用上容易感受到挫折及心理壓力，因而排斥接受新產品的使用及學習。但該族群的消費能力卻不容小覷，被視為具有強大消費能力的潛在市場。

以微單眼相機為例，其機體重量及大小皆較適合中高齡族群使用，在售價上也逐漸被接受。本研究首先設定典型任務，透過兩種操作模式-實體按鈕操作及螢幕觸控操作進行實驗，再以QUIS使用者介面滿意度問卷及NASA-TLX工作負荷指標問卷給予受測者進行填寫。結果顯示中高齡族群在操作上確實與青壯年族群存在差異，接著透過訪談找尋操作上的問題點，以及探討使用者內心感受為何，進一步訂定符合中高齡者使用的微單眼相機介面設計原則。

最後透過統計與分析，彙整出以下中高齡族群使用微單眼相機之使用性改良與建議如下：(1)足夠的操作說明與提示；(2)簡單易懂的功能選項詞彙；(3)以全顯示介面呈現選項；(4)水平式的操作選單；(5)避免使用複合式按鍵；(6)明確且清楚的操作回饋；(7)直覺且具引導式的觸控介面。

Nowadays, all developing countries face the problem of population ageing. As the rapid development of technology, the electronic products are created more and more. However, those products which are design for the elders are not common. While the elders get older, they have to face the phenomenon of physical ageing such as the regeneration of memory and comprehension. They might feel depressed and frustrated while using the new technology products. Nevertheless, the purchasing power for the elders could not be ignored.

Taking EVIL as an example, the weight and dimension of EVIL is suitable for the elders to use, and the price is also acceptable. This study is experimented by the two operation mode: the push-button operation and the touch-screen operation. Then the subjects of the experimentation have to fill out the QUIS and the NASA-TLX questionnaire. Therefore, the result shows that the operation for the elders is different from the youth. By interviewing with the subjects, the problems of operation and the feeling of using it could be discovered. Therefore, the EVIL interface could be design for the elders.

Finally, by the analysis of the experiment, the suggestion of the user interface for the elders using EVIL are as following:
(1) Clear manual and tips.
(2) Easy understandable vocabulary of function option.
(3) The whole options on the interface.
(4) Using the horizontal menu.
(5) Avoiding multifunction button.
(6) Specific and clear operation feedback.
(7) Direct and immediate touch-screen interface.
