以圖像關鍵字為基礎之兒童故事繪本搜尋系統

根據Nielsen Online研究報告指出，過去五年中兒童上網人數增長了18%。而故事繪本一直以來都是孩童閱讀書籍的主要來源。隨著數位內容與電腦科技的發展與進步，兒童在數位圖書館或網際網路上選擇合乎自身興趣的數位故事繪本也越來越重要。然而孩童在操作傳統關鍵字查詢系統進行找書活動時，往往因認知發展的不成熟而衍生出了許多問題。本研究希望透過建置故事繪本查詢系統，讓兒童以直覺的互動方式搭配可理解的圖像關鍵字組成操作介面，建構出適合兒童搜尋故事繪本的環境。本研究為調查以圖像關鍵字為基礎之兒童故事繪本搜尋系統之優使性，進行該系統之評估實驗，對象包含幼稚園大班20名、與國小二年級20名共40名孩童。評估實驗結果顯示，幼稚園大班孩童不論是找自己喜歡的書或是特徵找書，皆以故事繪本封面的角色為主要條件，而國小二年級孩童在想像力與觀察力方面，則呈現出更為細緻的搜尋條件建構。從找書任務與優使性問答來看，幼稚園大班的找書任務完成率與優性問答正確率皆比國小二年孩童之表現低。

With the advance of digital contents and computer technologies, how young children choose their interest digital storybooks in a digital library or on the Internet is becoming important. However, children often encounter difficulties in finding books with traditional keyword search interfaces due to the immaturity of cognitive development. Therefore, the purpose of this study is to develop an intuitive, iconic keyword search interface with which children compose comprehensible image keywords for their intended storybooks. This study also investigates the usability of the iconic keyword-based storybook search system for young children. The evaluation of the system involved 20 kindergarten and 20 second grade elementary children. The evaluation results showed that kindergarten children composed their search terms mainly based on characters on the book covers in both tasks of finding favorite storybooks and searching specific storybooks. However, the elementary children showing their imagination and observation demonstrated more detailed search terms by including elements of scenes of a book cover in the aforementioned tasks. For the usability aspect, elementary children showed higher rates of task completion and correctness of usability questions.
