本研究的目的在於開發一個應用程式以協助盲人或是因外在因素無法觀看智慧型手機螢幕的使用者，更容易使用智慧型手機的瀏覽器尋找資料。同時，附加了一些在日常生活中比較有用的小功能並加以改良。除了可報讀簡訊與電子郵件之外，本論文針對盲人上網的需求，實作出一個結合智慧型手機的免低頭應用程式，其中包含5個重要的功能: (1) 報讀網頁: 使用者可以利用Google搜尋引擎查詢資料，由程式自動唸出網頁內容。(2) 簡化網頁: 系統會自動過濾原始網頁上的廣告以及圖片，只呈現出文章中比較重要的文字內容，讓使用者可以快速地得知文章重點。(3)手勢偵測: 系統內的所有操作都使用手勢偵測以取代點選物件的功能。(4) 我的最愛清單: 應用程式可以儲存使用者有興趣的網頁，並根據使用者查看網頁的次數多寡自動進行清單的排版。 (5) 閱讀每日新聞: 使用者可以更方便的去聽讀每日新聞。我們並設計了特別的手勢以簡化操作選項。(6) 搜尋附近餐廳: 使用者可以搜尋附近餐廳，手機同時提供到達餐廳的大眾運輸轉乘及開車資訊。實作完成後，並請兩位盲人使用者測試，並運用單一受試法中的ABAB反向設計並與iPHONE的VoiceOver做比較。結果顯示本研究所開發之應用程式較VoiceOver為佳。

This study focuses on developing a head-down free smartphone application for blind people and those who may be inconvenient to watch the screen directly. In this paper, such an application program is implemented on an Android system to provide users with easy access to the web browser, and it also provides some utilities for blind users. Six features are proposed: (1) Read web pages: Web contents can be read out; (2) Simplify web contents: Advertisements and pictures in the original web pages are filtered out automatically, and only the article in text is left. Hence a user can find it easier to locate the text; (3) Gesture detection: six gestures were proposed instead of tapping to operate the application. These gestures are to replace the functions such as go to the next level, and select the icon, etc. (4) My favorite list: Store web links that users are most interested; (5) News: Daily news can be selected and read out easily; (6) Search nearby restaurants: Locate the nearby restaurants and provide public transportation information to those restaurants. Two blind persons and three students were invited to test out the proposed application. In this study, the proposed evaluation method is the single-object ABAB reversal design and we made a comparison between the proposed application and VoiceOver of iPhone. Results show that the test users feel that proposed application is better than VoiceOver.
