Idea generation support system GUNGEN DX II beyond papers

Abstract

We have developed a new idea generation support system, GUNGEN DX II. GUNGEN DX II supports the KJ method. GUNGEN DX II has two functions for handling a large number of ideas. The draft islands generating function supports the idea-grouping step of the KJ method. The function supports the grouping of many ideas intuitively by dropping an idea from the top of a window. The sentence convert function supports the sentence-writing step of the KJ method. The function generates a sentence using island titles semi-automatically. We carried out the KJ method using 544, 287 and 58 ideas. The results of the experiments are shown below. (1)Students could perform all the steps of the KJ method using over 500 ideas in one day. (2)If there are draft islands, students may be able to group more than 500 ideas. (3)More time was required for writing a sentence using 544 ideas.
