摘要

MP3 Player 所強調的是「體積小」、「便於攜帶」、「功能多樣」，在目前 MP3 Player 已經不僅僅是聽音樂而已，甚至包含 FM 收聽、語言學習 這些功能都需要使用者能夠清楚的從螢幕上獲取需要的資訊。因此使用者除了要能夠便於攜帶 MP3 Player 的需求外，也要能夠便於觀看螢幕。然而目前市面上一般用於攜帶 MP3 Player 的配件，其攜帶角度都為固定式不可調整，常會令使用者在瀏覽資訊的過程中造成頭部需要大幅度的轉動，甚至須要扭動手臂或是用手強制轉動 MP3 Player 才能達到瀏覽資訊的目的。本研究的目的即為，要使 MP3 Player 更便於攜帶且利於觀看。
本研究主要針對使用者對於 MP3 Player 的觀看角度及使用舒適度進行研究，實驗分成兩大階段，第一階段為「先期測試」，主要目的為能明確的了解 MP3 Player 使用者的「使用習性」。第二階段「後期測試」找來30位年齡介於16~45的受測者。針對手臂及腰部兩處攜帶位置做視覺角度的測試，其自變數為 MP3 Player 設備的垂直及水平兩個調整角度。最後得到30份測試數據，並利用「單因子隨機完全區集變異數分析」及 LSD 檢定，得到在手臂上最佳的瀏覽角度為75度、在腰部最佳的瀏覽角度為90度。且數據顯示水平調整角度的變化對於整體的瀏覽效率並無顯著差異。故本研究最後依照實驗出來的分析結論，提出兩種攜帶裝置的產品概念。

Current MP3 Player is gradually characterized by miniaturization, portability and multi-function. In addition to music function, MP3 Player even includes FM broadcast and language learning functions. In general, most functions of MP3 Player need to be manipulated by users through the screen. Therefore, MP3 Player should enhance users’ facilitation in browsing screen besides portability. However, users still have to substantially make use of their heads, arms or hands for browsing information on screen due to fixed cradle of MP3 Player in the market. This study aims to make MP3 Player more convenience in portability and browsing.
Mainly aiming at users, visional angles and comfortable usage toward MP3 Player, this study divided the experiments into two stages. The first stage is the pilot test which aims to positively investigate MP3 Player users, habits. The second stage is the post test collecting 30 subjects (whose age ranges from 16 to 45 years old) for visual angle testing on two portable positions - arms and waist, which taking vertical and horizontal adjustable angles of MP3 Player devices for independent variables. According to one way ANOVA with Randomized Complete Block Design and Least Significance Difference (LSD) test on the 30 test data, the optimum browsing angle on arms and waist was 75° and 90° respectively. Besides, the data showed there was no significant difference between the variation in horizontal adjusting angles and the whole browsing efficiency. Therefore, the study proposed two product concepts of the portable device according to the final analysis conclusion of the experiments.
