在這科技發達的時代裡，行動裝置的使用是越來越普遍。儘管如此，行動裝置仍有一些限制，譬如礙於攜帶方便，需要使用比桌上型電腦小型的螢幕，因此當使用者透過已往的瀏覽器觀賞網頁時，在網頁沒經過裁剪的狀況下，使用者必須不斷移動頁面或多次點擊連結才可以看到完整的網站內容。此外行動裝置上必須藉由有限的網路頻寬來取得網站的資訊。若要將一般瀏覽器中所有資訊都呈現在行動裝置上，會造成速度嚴重延遲。這些種種原因，都會影響使用者是否喜歡使用此應用程式或行動裝置。為了解決這些問題，本論文針對行動裝置上瀏覽網站，首先從相關的文獻中收集有用的原則，並依此條件實作出具親和的網站內容介面。接著，本應用系統再依據各種行動裝置的格式作轉換。而轉換方式包含兩種，其中一種是專門針對Android裝置設計，可將網站轉譯成Android裝置上可呈現的使用者介面元件；另一種是將網站轉譯成一般行動裝置皆可瀏覽的樣式。本論文是透過一個行動裝置上的新聞網站應用程式來驗證我們所設計的原則和轉換機制。 The usage of mobile devices to access various services becomes more and more popular in our daily life. However, mobile devices have their essential limitations such as smaller screen sizes than desktop ones in order to carry with ease. Without any tailoring to represent Web content on mobile devices, mobile device users have to scroll Web pages or click links in a tedious manner to view complete content of websites that are originally designed for desktop users. Besides, mobile devices have limited network bandwidth to retrieve remote Web content. If the whole Web content dedicated to the display on general browsers is transmitted to mobile devices, it will cause an unpredicted delay when showing the content on mobile devices. Due to these limitations, users usually are not willing to use browsers of mobile devices to view Web content. In order to solve the problems, this thesis first collects several useful guidelines from literature to design friendly user interfaces for mobile devices. Then, we also devise rules to transform original Web content into the ones that are customized for various mobile device platforms. Currently two kinds of transformations are proposed: 1) transcoding websites into Android components for Android-based mobile devices; 2) transcoding websites into web pages for general mobile devices. Finally, a news application on mobile devices is developed to demonstrate our design guidelines and transformation approaches.
