博士 === 國立成功大學 === 工業設計學系碩博士班 === 92 === This study develops curtain selection and spatial arrangement models based on the image compositing approach to assist consumers, designers and furnishing professionals in optimizing curtain form and spatial arrangement. First, this study evaluates the realistic effect of image compositing in assisting decision makers in curtain selection, and explores the influences on the realistic effect of curtain image compositing. Second, this study examines the effects of different texture color on realistic effect of curtain image compositing and compares furnishing professionals and general consumers in evaluating the realistic effect. Third, this study develops a decision supporting model by integrating the image compositing approach with the Taguchi method to assist decision makers in optimizing the curtain form for various aesthetic feelings. Finally, this study constructs a decision making model by combining the fuzzy analytic hierarchy process (FAHP) approach with the image compositing technique to help decision makers optimize the spatial arrangement. The analytical results show that grayscale contrast, texture pattern and texture opacity are significant factors influencing the realistic effect of image compositing. Furthermore, the optimum overall realistic effect reaches 0.95 with the combination of 60% grayscale contrast with small texture pattern and 60% texture opacity, indicating that the image compositing approach can effectively be applied in the furnishing related industries. Regarding the evaluation of different texture color to overall realistic effect, light colored textures (golden yellow, orange and light green) were significantly greater than dark colored textures (dark blue, brick red, dark green). Additionally, no significant disparity in assessments existed between furnishing industry professionals and consumers. This phenomenon indicates that consumers should consider the suggestions of furnishing professionals, and obtain immediate verification through virtual images on computer monitors. The four form factors, curtain body, valance, sheer and cascade, influence curtain aesthetics. Based on the S/N ratio with respect to the response graphs, the optimum curtain form can be determined for various aesthetic feelings. Additionally, the relative importance of the form factors affecting curtain aesthetic feelings can be obtained via conjoint analysis. The curtain body is a significant form factor for elegant, practical and harmonious feelings, sheer is a significant form factor for modern feelings, and cascade is a significant form factor for romantic and luxurious feelings. Furthermore, this study applies the fuzzy analytic hierarchy process (FAHP) approach to a multiple criteria decision-making process comprising rational and emotional choices. The process involves setting evaluation criteria, constructing a fuzzy judgment matrix and weight vector, and then ranking candidate alternatives by a fuzzy number in the fuzzy sequencing vector. This FAHP approach can allow decision makers to determine the optimum spatial arrangement. Also, creation of an artificial spatial arrangement image by the image compositing technique enables decision makers to see the future completed work before starting renovations, and enables emotional judgment of the spatial image. The approaches proposed in this study can be extended to furnishing related industries to improve curtain selection and spatial arrangement efficiency, minimize communication time with consumers, promote sales, and improve the degree of satisfaction for consumers, designers and manufacturers.
