Development of More Concept Words Leads to the Generation of More Idea Sketches

Abstract

AbstractIn this study, we evaluated the performance of designers’ idea development using the IDEATOR app as the designers’ ideation tool and investigated whether there were differences in behavior linkages and idea sketches among designers from three design fields. The results were as follows: 1. According to our analysis of the video data recorded by designers using IDEATOR, their behaviors included nine behavioral codes separated into three behavior modes (GI, GA, TH) and an error action code; 2. The designers used IDEATOR for ideation and most frequently engaged in GI behavior, especially those in the fields of graphic and product design; 3. The designers who used IDEATOR for ideation had a tendency to frequently develop concept words. In particular, graphic designers were highly dependent on word-type data to perform the ideation process; and 4. The more input concept words on the interface of the IDEATOR mind map employed by the designers, the more idea sketches the designers drew. As they input additional concept words, the designers also produced sketches that fit into multiple lateral thinking categories.KeywordsDeveloping HCI expertise and capability worldwideDesign thinkingIdeation
