電腦與網路的使用日漸普及，中高齡族群使用電腦的人口比率逐年增高，但目前所設計的電腦選單介面，對中高齡使用者有操作障礙。近年來市場上出現一項新的電腦產品，宣稱可以讓全年齡人口都能使用的桌上一體成型觸控電腦(All in One)，可以直接以觸控操作特製的電腦選單介面，不需要透過滑鼠與鍵盤。本研究的目的有三項，(1) 了解中高齡族群電腦網路使用現況；(2) 研究符合中高齡族群使用的電腦選單功能架構設計；(3) 研究滑鼠與觸控兩種操控方式，對於中高齡使用者操作電腦選單的影響。

根據研究前期所施行之中高齡者電腦網路使用行為調查問卷結果，有效問卷的117位中高齡受問卷者中，最期望電腦與網路能提供的功能服務排序是: (1) 報紙功能45.3%；(2) 健康/醫療功能39.3%；(3) 相本功能35%；(4) 股市功能35%、(5) 旅遊功能32.4%；(6) 影片播放功能31.6%。此六項功能在經過設計之後，成為驗證實驗的功能介面操作測試項目。本研究包含兩部分實驗，分別是前導性實驗與驗證實驗。前導性實驗蒐集三件桌上一體成型觸控電腦，分別是MSI AE2020、ACER z5600、HP Touch smart IQ500，以觸控操作的方式，就其特製之電腦選單介面進行任務測試。結果顯示，系統穩定性高、可編輯的電腦選單、固定已習知的功能項目位置、有文字標示的功能項目、有明顯標示的可互動區域與尺寸放大的文字顯示，都可以增加中高齡使用者的操作時間績效，研究者針對這些要點設計出驗證實驗中的實驗介面。

驗證實驗為2 (操控型式) * 3 (選單介面功能架構型式)獨立樣本雙因子實驗。「操控型式」之變項有兩個層級：滑鼠操控與觸控操控。「選單介面功能架構型式」之變項有三個層級：(a) 功能物件式介面：功能項目以3*5的方式，平均排列在選單介面上；(b) 操控面板式介面：功能項目並排在介面下方，形成固定呈現的操控面板；(c) 智慧型顯示介面：每個功能項目包含一個智慧型顯示區域，可顯示即時資訊。透過實驗可獲得操作績效、介面互動滿意度、系統使用性與使用者體驗感受之結果。

研究結果如下：(1) 有95%接受問卷者家中有電腦設備，卻只有62%的中高齡者曾經使用過電腦， 82%的中高齡者期望電腦操作可以變更簡單；(2) 智慧型顯示區域設計，可以有效水平化介面架構，提高整體操作績效；(3) 低知識需求的功能操作邏輯，操作限制較小；(4) 功能操作過程需要清點、統計物件數量時，觸控操作明顯優於滑鼠操作；(5) 轉場換頁次數少的功能介面，可以得到較高的操作績效；(6) 滑鼠操作與觸控操作間差異不明顯，觸控操作較直覺不需學習，但只要功能選項夠大，滑鼠的基本操作對中高齡者障礙度低。

The use of the computer and network is popularized day by day. The population of computer user of middle and elderly age groups increase year by year in China, but the design of computer menu interface is difficult to use on contemporary middle and elderly age user. Recently there appeared one new computer product in the market, and the company emphasized that the ALL IN ONE computer can be used by whole age people. It can be operated by finger touch on special computer menu interface, and does not need to use a mouse or a keyboard. There are three purposes of this study, (1) Find out the using ways of computer and network of middle and elderly age groups ; (2) Study the computer menu function structural design of the ones that accord with the middle and elderly age groups ; (3) Study the influence of using computer menu on the middle and elderly age groups with two kind of operation type－ mouse and finger touch.

According to the study result of the using computer and network behavior questionnaire on the middle and elderly age groups, there are 117 people who receives questionnaire and hope computer and network can offer the function service: (1) The function of newspaper is 45.3%; (2) The function of health and medical is 39.3% ; (3) The function of photo album is 35%; (4) The function of stock market is 35% ; (5) The function of travel is 32.4% ; (6) The function of play movies is 31.6% . The six functions have had designed to prove the test project of experiments. This research study includes two parts of experiments, including leading the way experiment and verifying the experiment. Collect three kinds of ALL IN ONE computer, including MSI AE2020, ACER z5600, HP Touch smart IQ500 in leading the way experiment. Execute the task to test to the purpose-built computer menu interface by finger touch. The result shows, the higher systematic stability, computer menu that can be edited, regular the function icon position which had been already known, function icon with explanatory note, interaction area with obviously label and the characters enlarged to show can increase the use of time by experimenters, the author according to these main points to design the interface of verifies experiment.

The experiment was planned based on a 2 (controlling model) by 3 (function structure model of interface menu) two-way ANOVA design of independent sample. There are two levels in the variable of controlling model: Mouse controlling and Finger Touch controlling. There are three levels in the variable of function structure model of interface menu: (a) Function project interface: The function icons is arranged on the menu interface equally by the way of 3*5; (b) Controlling panel interface: The function icon is below the interface side by side and form the regular control panel that appears; (c) Intelligent interface: Each function icon include one intelligence area, can show instant information. Base on the experiment, the results show users performance, questionnaire for user interface satisfaction (QUIS), system usability scale (SUS), and get the experiences by users.

The results of study : (1) 95% middle and elderly age groups who accepts questionnaire had computer equipment in their home, but only 62% people had used computer, 82% people hope the computer can become simple to use ; (2) Intelligent display area effective level interface structure, wholly raise the functions of operation; (3) The function of the low knowledge demand operates logic, the limits of operation are relatively little; (4) When the course of function operates need to check or count the quantity of the things, the controlling model of finger touch is obviously better than controlling model of mouse to operate; (5) Change few function interfaces of the page, can get the higher operation performance; (6) The difference between mouse controlling and finger touch is not obviously in the experiment, controlling of finger touch intuitive does not need to study, if function icon is bigger; the controlling of mouse is easy to use for the middle and elderly age groups.
