Structural Model of Sketching Skills in Product Design

Abstract

In this paper we clarified the relationship between sketching skills and idea generation in the process of product design and proposed a structural model of sketching skills. Specifically, we discussed the acquisition process of sketching skills as observed in a sketching class and evaluated sketches drawn by its students. By analyzing the evaluation results we identified eight elements that constitute sketching skills and proposed a structural model explaining the relationship among those elements.
