臺灣博碩士論文加值系統

隨著數位單眼相機的普及化、以及分享照片的社群網站被廣泛使用，網路上累積了相當大量由使用者所提供的照片。現今數位相機所拍攝的照片檔案裡含有相機自動寫入的拍攝資訊，可代替傳統手寫紀錄的方式供使用者學習相關攝影知識；然而，現有的照片搜尋系統並沒有提供一個良好的使用者介面輔助使用者以拍攝資訊為條件搜尋照片。基於此，針對攝影初學者學習的需求，設計並建置一個基於相機操作的照片搜尋系統雛型是本研究的主要目的。
為了探索照片內含有的拍攝資訊(EXIF)在照片搜尋系統上的應用，本研究分為系統建置以及系統測試兩個階段。系統建置階段針對相機操作的學習需求，分別探討預覽場景、搜尋條件、控制項與版面設計，設計並建置一個照片搜尋系統的雛型，並且利用網路上現有的大量Flickr照片、以及照片內的EXIF資訊建置後端資料庫。系統測試階段則先選擇使用者對系統雛型操作，並進行了使用者的訪談、再於網站進行較大規模的線上使用者操作測試與問卷填寫；結果顯示，無論單眼相機使用資歷的使用者為何，系統使用性及互動滿意度方面皆得到正面評價。最後，本研究彙整問卷以及訪談結果，歸納出搜尋功能以及介面設計的相關建議。

With the popularity of Digital Single Lense Camera (DSLR) and the widespread establishment of various picture-sharing communities, the Internet has accumulated a huge amount of photos. Digital Photo files included photography information called EXIF（Exchangeable image file format） which digital cameras tagged automatically. The mechanism can replace the traditional way of photographic recording manually. However, the existing photo search system does not provide users with good auxiliary tools to search photos with queries employing the tagged photography information. Therefore, we explore the support for novice DSLR users by designing and developing a system prototype of photo search system with emulated camera controls.
In order to explore the application of digital photographic information embedded in digital photo files, this research synthesizes the demands of photographic skill and camera controls, implemented a system prototype for learning DSLR photography. This implementation and system testing comprises the two phases of this study. In system implementation phase, the scene of the preview, the conditions for searching queries, controlling operation and interface layout are investigated and scenario of interfaces for searching are elaborated. We also utilize the large amount of existing photos on Flickr and EXIF information to build the database for retrievable photos. The system testing phase includes the selective users testing and interviews, and online web users testing with questionnaire. Results from these testing show that the system usability and user interactive satisfaction are quite positive. Finally, this study derives recommendations for future exploration and implementation from the summarization of questionnaires and interviews.
