摘　　要：草图是设计师进行产品设计创新活动的重要载体.草图设计是设计师的脑、眼和手三者互动,设计思维和草图表达相互推进的过程;草图设计过程可以抽象为创意拐点图.为了对草图设计过程提供有效的支持,本文提出了一种基于创意拐点的计算机辅助草图设计技术.建立了基于草图行为识别的创意拐点规则推理模型,基于该模型来识别草图设计过程中的创意拐点,并通过对规则进行粗粒化来解决模型的过拟合问题.在此基础上,生成作为草图设计过程记录的创意拐点图,以记录创意过程,辅助设计师草图设计.最后构建了基于创意拐点的计算机辅助草图设计原型系统CASCP,并通过实验初步验证了创意拐点识别方法的有效性,给出应用CASCP完成的草图设计实例.Sketch is an important creative tool for product design. In the sketching process design thinking and sketch expressing promote each other, involving the interaction between designer’s actions of brain, hand and eye. The sketching process can be described as a Creative Point graph. This paper proposes a computer-aided design method based on Creative Point to support sketching process. This method recognizes sketching behaviors, and distinguished Creative Points by constructing a Creative Point rule base, and refines the rule base to avoid overfitting. A Creative Point graph is also created to record the design process and support designers’ sketching. Finally, a computer-aided sketch system prototype CASCP is developed using the method, which proves effective in Creative Point recognition. A sketching case using CASCP is also presented.
