近年來受到網際網路普及和電腦科技的發展,「數位閱讀」一詞開始在學界與實務界廣泛討論,並且逐漸影響人們的閱讀習慣。數位閱讀無論是內容的呈現或者閱讀行為上都與傳統紙本閱讀有很大的差異。本研究整理國內外有關數位閱讀的文獻作為研究基礎,並且將數位閱讀的範圍聚焦於兼有出版紙本形式的數位內容,例如電子書、電子期刊、電子雜誌等,以探討當前數位閱讀行為與紙本書籍閱讀行為二者間的差異。並且對於平板電腦、電子書閱讀器等新興載具對於閱讀行為產生的影響做進一步的探討。本研究分為兩個階段,第一階段透過問卷調查方式收集資料以探討分析數位閱讀市場的現況,了解臺灣地區數位閱讀市場中,主要族群的相關行為與習慣。第二階段則針對使用者在不同載具上的數位閱讀行為進行研究,了解不同載具上使用者的閱讀績效之差異。從調查結果可歸納出臺灣地區的數位閱讀主要族群為20至30歲,此族群普遍有數位閱讀習慣,且閱讀頻率相當高。以此為依據所進行的第二階段的閱讀實驗結果則發現平板電腦上的閱讀績效明顯優於其他載具,甚至於較使用者所習慣的筆記型電腦更佳。可見在數位閱讀的推廣上,除了可針對數位閱讀的主要族群進行設計外,亦可將載具因素納入考量。此外根據研究結果可推論平板電腦在深度閱讀以及學習上有較佳的表現,可做為未來數位學習平台的選擇。With the popularity of the Internet and the development of computer technology, digital reading has raised many researcher and practitioners more attentions and affected the human reading style. In essence, digital reading habit is different from the conventional reading in the contents or reading behaviors. In this thesis, drawing on the related literature, the aims of this thesis primarily focus on investigating the differences in reading behaviors between the digital reading and paper form reading, and also further exploring the impact of the feathers of the Tablet PC and eBook on the reading habits.The study included two stages. In the first stage, this thesis used questionnaire survey with an aim to explore the reading habits in Taiwan. In the second stage, this thesis employed the experimental method to understand the difference in the reading behavior between different devices.The survey result showed that the group in the age range from 20 to 30 years old primarily relied on digital reading. The persons in this group almost developed digital reading habits, and the frequency of digital reading in this group was higher. The experimental results in the second stage showed that the reading performance on the Tablet PC is superior to on other devices. Therefore, to develop the digital reading, producing the design for the groups of digital reading is important for researcher and practitioners. In addition, the device factors should be taken into consideration while developing the digital reading. The results suggested that compared with using other digital reading devices, the person using a Tablet PC in depth reading and learning exhibited better performance. In conclusion, Tablet PC should be the most appropriate device for digital learning platform in the future.
