摘要

在攝影和電影運鏡中，人們較容易遺忘光影的重要性，但在電影中，光線卻是畫面的核心要素之一，也是一種能為作品帶來不同感受的元素。因此本研究針對光影模擬，開發了以行動裝置為主要平台的教學輔助工具「Capturing Light」，主要研究目的為：(1)以3D模型建構虛擬室內外場景(2)利用模擬的方式，呈現光影的各種特性 (3)結合電影運鏡，觀察運鏡中的光影變化。本研究使用科技接受模型探討使用性，依55位參與者之問卷結果進行分析，並綜合使用信度分析、敘述性統計分析、相關性分析以及迴歸分析等，驗證各構面之間的相關性。研究結果發現以下四點：(1)使用者對此教學輔助工具保持著滿意的態度 (2)三構面之間皆有中度正向相關性 (3) 認知易用性與行為意圖之間不顯著(4) 認知易用性與認知有用性和認知有用性與行為意圖之間有極顯著的正向影響關係。依此結果，初步推論以APP的形式可以有效輔助攝影和電影運鏡的學習，並且可透過行動裝置模擬各種光影的特性，達到行動學習環境，有效提升學習成效。

In camera movement of cinematography, people often neglect the importance of light. Yet in cinematography, the light is one of the core elements of the screen. It also played a key role in presenting the different feelings for the film. This study aims at the simulation of light. We developed a prototype for mobile devices as the main platform of CAI(Computer Assisted Instruction). The main purposes of the study are: (1) Constructing Virtual Indoor and Outdoor Scene with 3D Model. (2) Using simulation as the way of showing the various characteristics of light and shadow. (3) Providing users with the simulated camera movement for user manipulation and observation the changes in light. This study uses TAM (Technology Acceptance Model) to explore usability to analyze the results from the questionnaire of 55 participants. The reliability analysis, descriptive statistical analysis, correlation analysis and regression analysis were used. The results of the study are summarized in the following: (1) Users are satisfied with the teaching aids in general. (2) There are moderate positive correlations between the three facets. (3) There is no significant difference between perceived ease of use and behavioral intention to use. (4) There are significant positive correlations between perceived ease of use and perceived usefulness, perceived usefulness and behavioral intention to use. Through these results, we could envision the potential of developing CAI in APP form can effectively assist in learning cinematography and can simulate the characteristics of various light and shadow through the mobile device. This approach demonstrates a way to achieve a ubiquitous learning environment for effectively improving learning outcomes.
