碩士 === 國立交通大學 === 應用藝術所 === 88 === Design, which was generated by people with complex mental behavior, is a well-thought and deliberate activity, including more rational and logical thought. In the design process, the key of design thinking is the knowledge within and/or between shape recognition and transformation. Recently, there are many researches, which study designers’ activities during sketching stage of design process, by cognitive experiment. On the other hand, in the area of visual cognitive behavior simulated by computer, symbolic systems can’t simulate how people recognize the shapes and associate from one shape to another. However, neural networks can manipulate this kind of simulations. Moreover, neural network also can recognize incomplete shapes and retrieve some attributions of shapes from long-term memory (LTM). In the first part of this thesis, the objective is to study how designers generate one-element product in terms of shape associations and evaluations. Moreover, simulating this activity, which occurred during idea generation stage, by neural networks evaluates that can computers think as well as designers. Therefore, computer systems not only simulate the visual behavior of designers, but also generate new ideas which can be sued in the design. The objective of second part is to investigate how designers generate ideas of multi-component product, and to simulate this phenomenon by neural networks. At the same time, this part tries to inspect the design cognitive behavior of the idea-generating stage, and to explore the designers’ cognitive phenomenon.
