Digital Design Sketch for Product

So far the effort of digitalizing product-styling tools for the early design development stage has mainly focused on using raster-type graphics S/Ws. However, it has become a new obstacle to concurrent engineering because resultants of these S/Ws are no more than images, which can be hardly converted to digital forms required by downstream process. For resolving this problem, this paper suggests the digital design sketch based on the observation and analysis of design-sketch elements and behaviors. The proposed method not only allows designers to perform their creative work sensually by adopting user-friendly interface based on their traditional design sketch, but also provides a digital connectivity with downstream process by handling strokes as vector-type data.
