本研究的目的在於建立一設計流程。以數位相機為例，以多元尺度法分析各種數位相機造型的分佈與相似度。並將造型特徵轉化為基因編碼，配合遺傳演算中適者生存的特性，演化改良出適合手部握持的相機輪廓。
　　在設計師進行產品發展時，常採用的是傳統手繪技術繪製草圖後再進入CAD系統。此過程往往會消耗大量的時間，尤其是進行與手部操作相關性較大的產品如數位相機、滑鼠、PDA、手機或是一般手工具等。除了考慮產品造型，更需要考慮到操作握持時的穩定性和舒適度。目前的設計軟體功能雖然強大完整，但對於操作型態方面並沒有給予使用者完整的資訊。面對消費者對於產品操作感受需求日漸增加的時代，在設計的過程中導入產品操作性的考量是有其必要性。
　　本研究中運用了遺傳演算法，對於目前市面上的各種數位相機進行編碼，並在遺傳演化的過程中導入操作型態、體積變化、造型變化的評分考量，讓相機逐漸改良成適合於操作握持的型態。並將演算結果以特徵值的方式儲存，以節省資料空間。利用visual c++所建立 3D Shading 系統對於演化的過程進行立即的演算和呈現，讓操作者更容易瞭解相機造型的變化。

　　In this paper, we present a computer aided design process about digital camera form design by using multidimensional scaling method and genetic algorithms. In design process, designers need to consider not only the product form but also the comfort of handling objects, such as digital camera, PDA, mouse, mobile phone, joystick, game console, etc. It is necessary to consider the comfort factor of product handling in a form design software system in the generation of consumerism.
　　The relationships between the digital camera form and for image will first be quantified by using questionnaires and multidimensional scaling method. Then a CAD system is built using the genetic algorithm, based on the obtained data, for constructing 3-D model of a product by Visual C++. Then final results of the evolved digital camera can be acquired as a reference for the designer/consumer to design/select the prefer design/product.
