電腦繪圖表現方法對於傳達產品外觀效果之研究

在產品開發的過程中與遠距共事設計中，設計師的角色除了做好設計工作之外，還有一項重要的責任，就是將心中的構想忠實的表達出來，讓決策者在產品尚未生產前，了解產品的造型、色彩、質感與機能。而平面的表達方式不外是：三面精描、透視圖精描、動畫等。而本研究主要探討三面圖、透視圖、動畫、影像式虛擬實境等四種表現技法之中，何種技法能忠實地表達產品外觀造型，這些不同的表現技法特點何在，及不同教育背景族群間是否有判別認知的差異。本研究先以分群實驗法與多向度評量法，找出一般判別產品造型差異的準則，可分形狀、色彩、線條、質感為四類判別屬性。本研究再透過屬性配對實驗的方式，讓受測者將螢幕表現物與實物做成配對，藉以了解各個表現技法在各個屬性上的傳達效果，以找出一般判別產品造型屬性與技法間關係，分析上述四種視覺傳達技法之正確率及偏好性。本研究之結果將供設計師在產品開發中做為選用工具媒體的參考，以便減少不必要的誤解，提升產品開發效益與設計競爭力。

During the process of product development and collaborative design, designers often need to communicate their designs visually and accurately, among themselves, to target consumers, or to decision makers, about the various aspects, such as shape, color, texture, and functions, of the designs. To communicate their ideas, designers have learned to use three-orthogonal-view drawings, perspective drawings, as well as computer graphics. However, some graphical presentation methods might be easier to understand than others. The objective of this research is to determine the characteristics, and the relative strengths and weaknesses of the common presentation methods, including three-orthogonal-view drawings, perspective drawings, computer animation, and image-based virtual reality, with respect to viewers of different educational background. This research first determines the criteria by which viewers evaluate the appearance of a product through a series of surveys. Next, the effectiveness (or accuracy) and preference level of each presentation method is evaluated by conducting experiments, and analyzed by using ANOVA and multidimensional scaling analysis. Finally, the results are summarized as a reference for designers to choose one or more presentation schemes that can better communicate important aspects of their designs, thus reducing the possibility of misunderstandings.
