电脑技术的广泛运用,使人们在设计中过分依赖电脑,对写生和手绘草图的训练失去了应有的热情,最终导致设计者的造型能力和思维能力降低。本文主要是讨论写生和手绘草图的重要性,根据“眼、脑、手、图形”四位一体原则,分别从视觉,大脑,动手和图形表达这几个方面分析了它们的关系和相互作用,并强调它们在启发设计思维和创作灵感中的意义。并希望人们在熟练运用电脑的同时,重视手上功夫的训练,保持设计原创的灵感和热情。 Extensive use of computer technology, so that people rely too much on computers in the design, drawing and hand-sketched training lost the enthusiasm, and ultimately lead to the designer’s modeling ability and thinking ability to reduce. This paper mainly discusses the importance of sketching and hand-sketched sketches. According to the four principles of “eyes, brain, hand and figure”, this paper analyzes their relations and mutual relations from the aspects of vision, brain, Role, and emphasize their meaning in inspiring design thinking and creative inspiration. I hope people will pay more attention to the training of their hands while keeping abreast of computers and keep original design inspiration and enthusiasm.
