摘要

本研究藉由從傳統類比式控制介面轉換成數位控制型態的數位相機進行中高年齡層使用者介面探討。針對操作績效與心理層面進行探討與分析，建立中高年齡層介面設計之參考依據。具體目的歸納如下：1.調查中高年齡層使用者之需求與使用性問題點，設計出符合其需求之介面。2.利用模擬操作介面給予任務操作，分析數位相機介面的顯示形式對中高年齡層在操作績效與心理層面的影響。3.發展適合中高年齡層使用者族群的介面設計原則與參考依據。研究分為兩階段進行，第一階段透過問卷調查、任務操作探討中高年齡層的使用現況與需求，進行模擬介面取樣。第二階段因前期調查歸納出切換選單非常重要，所以探討選單預視功能，設計出兩款不同預視功能的操作介面「全預視顯示」、「半預視顯示」，加上現有介面「無預視顯示」共三款介面進行評比，利用PDA作介面操作模擬，進行任務操作績效實驗，調查三種介面之操作績效、工作負荷指標NASA-TLX與SUS主觀感受分析。本研究所得結果如下：1.功能選單提供預視功能，對於中高年齡層使用者，的確具有較好的使用性。2.半預視選單僅提供上一與下一的選項預視，有最好的操作績效與使用性，介面呈現方式提供使用者了解下一步即將遇到的使用狀態，相較於一般介面使用的無預視顯示有較好的使用性。3.全預視顯示將所有功能皆呈現在介面上，其操作績效沒有半預視顯示好，所有功能皆出現在選單上，讓中高年齡層使用者可以完全掌控介面使用狀態，而其缺點在於太多選項在搜尋時相對的也較花時間。
關鍵詞：數位相機、使用者介面、中高年齡層、預視性。

This research probed into the user interface for middle-aged people, exploring the digital controled camera interface that developed from traditional analog control interface. By explored and analyzed operating performance and psychological effect, this research aimed to establish the interface design references for middle-age people. Specific purposes are summarized as follows: 1. Investigate the user needs and usability problems of middle-age people. 2. Utilize simulation interfaces and given operation tasks, analyzed the impact of the interface operating forms to the operating performance and psychological effect for middle-aged people. 3. Establish the interface design principles and references suitable for middle-age people.
There are two stages of this study: first stage, use questionnaire survey and task operating to explore the the user need and middle-aged people current using situation, then sampling the simulated interface elements. Second stage, preliminary investigation summarized that the switching between menus are very important, hence this research probe into the menu with preview function, designed two kind interfaces of different preview function: “whole pre-show display” and “half pre-show display”, and exist interface “non pre-show display”, utilized PDA displayed simulating interfaces.Then estimate the performance of tasks operating, workload indicators NASA-TLX and SUS subjective feelings analysis.
The result of this research: 1. Menu providing pre-show function indeed has better usability to middle-age people. 2. Half pre-show display provide the previewing of last and next item, has the best operating performance and usability. 3. Whole pre-show displays has worse operate performance than half pre-show display, it put all items on the screen,let older age people can complete control over the interface, the shortage is spending relatively more time.
