摘要

本研究旨在藉由使用者心智模式之角度探討MP3播放器操作介面之使用性，並根據前導測試結果提出新型設計加以研究探討。
本研究首先以量性、質性之方法先針對現有MP3播放器進行於使用者操作績效、使用感受作分析比較，再依據文獻研究與前導測試所得之結果，建構兩款新型之MP3播放器模擬介面，並把新型模擬介面再次進行操作任務實驗以及問卷、訪談，以提供更全面之研究結果。本研究所得結果如下：
(1) 操作績效與使用者偏好並無絕對之影響關係。在先前研究中，Ipod測試樣本比Sony測試樣本於使用者有較低的操作績效，卻反而有較高的主觀評價；並且在正式實驗中，使用者亦偏好使用起來感受較愉悅、互動性、視覺效果較高之樣本介面，而非操作績效較高之樣本介面。由此可知MP3操作介面之設計若一味追求使用性之操作績效，而忽略了消費者的主觀看法，即無法滿足消費者之喜好。其中本研究觀察指出，視覺效果佔使用者偏好很大的影響因素，尤其動態效果、圖像設計、色彩之視覺效果的美觀與否，影響使用者偏好最深。並建議MP3播放器應適當的增加動態效果以協助使用者建立操作產品正確之心智模式並增加操作之愉悅感。
(2) 圖示式介面呈現較標籤式介面在使用者感受上佔優勢。在本研究正式實驗中，圖示式模擬介面比起標籤式模擬介面雖然於受測者操作績效上並沒有顯著差異，但是在使用感受、互動性、視覺、架構表達形式、SUS使用性、QUIS滿意度之不同面相上，受測者主觀感受皆有顯著的差異存在。因此以圖像為主(文字為輔) 比起文字為主(圖像為輔)之選單呈現介面能給使用者留下較深刻之印象，亦有較高的評價。並且從本研究之受測者訪談了解，若首頁之功能選單能提供下一功能階層之預視，可以提升使用者在操作介面時之信心與信賴感。
(3) 年輕族群與中老年族群使用者對同一呈現方式之模擬介面在看法上並無顯著差異。意即能滿足單一族群卻讓另一族群困擾的介面設計在本研究之中並無觀察到其存在。模擬介面若在年輕族群中評價越高、在中老年族群中亦評價越高。

The aim of this study is to investigate the usability of the operating interface of MP3 players in terms of the user mental model and to propose new models based on the results of the pilot test.
This study first applied both the quantitative and qualitative approaches to analyze and compare users’ operating efficiency and feelings about MP3 players. Then, two novel, emulated MP3 player interfaces were developed according to results of the literature review and pilot test. A practical test, survey and interviews were conducted on these two interfaces to provide full-scaled research results as shown below.
(1) The effect between operating efficiency and user preferences is indefinite. In the pilot tests, the operating efficiency of the iPod samples is lower than that of Sony, but the former has better subjective ratings. Also in the practical test, instead of interfaces with higher operating efficiency, users prefer interfaces with pleasant feelings, interactions and better visual effects. As such, it is clear that designers seeking to enhance the operating efficiency of MP3 players without considering the subjective views of consumers will be unable to fulfill the consumer preferences. Observations of this study also indicate that visual effects play a decisive role in user preferences, particularly the dynamic effect, iconic display design and color scheme, which are the essentials of user preferences. Therefore, it is recommended that MP3 player designers should add suitable dynamic effects to their products in order to help users establish a correct mental model of product operations and to increase the pleasant feelings of product use.
(2) The effect of iconic interfaces is superior to tab interfaces. In the practical test, though the difference in operating efficiency between iconic and tab interfaces is insignificant, the difference is significant in the subject feelings of users between both types of interfaces in terms of user feelings, interaction, visual effect, structure expression, SUS usability and QUIS satisfaction. Therefore, menus presented in iconic interfaces (with text tips) impress users more than tab interfaces (with icon tips) and have better comments. Results of interviews indicate that if previews of items in the submenus are provided in the function menu in the first page, this can increase the confidence and trust of users in operating the interface.
(3) The difference in the same emulated interface between young and old users is insignificant. This suggests that the interface design satisfying one user group will not bring trouble to another group according to this study; i.e. emulated interfaces have better comments in the young user group also have the better comments in the old user group.
