| Summary: | 碩士 === 國立交通大學 === 電機資訊國際學位學程 === 99 === Electronic-book, e-book, is a fast growing service for mobile Internet. A user reads e-books through an e-book reader, e-reader, which can be a dedicated reading device or an application on a smart-phone. A key criterion for e-reader design is to provide good user experience, which means rich features and fast access time. This thesis presents an evaluation method of e-readers regarding the user experience. This method includes a feature and functionality analysis and a detailed performance evaluation of tested e-readers. Moreover, surveys are conducted among NCTU students to collect their opinions and feedback about their e-reading experience. One of the main findings is that the loading time is a critical issue especially for Digital Right Management (DRM) protected e-books. To reduce the waiting time, we propose a preloading mechanism that preloads a small number of chapters into the buffer. The mechanism can improve the user experience and still assure the required protection level for the e-book.
