This study proposes a new brainstorming method, Text Montage . The term montage refers to the famous experiment in film editing by Lev Kuleshov , who demonstrated the effect when people try to interpret the meaning from a pair of images subliminally. In the case of Text Montage people can make leaps of imagination with neologisms (new phrases) generated in a pair of words To verify the validity and usefulne ss of th e method, we designed a novel brain storming groupware KOTOBA JAM. In the usual brainstorming methods , participants find it difficult to come up ideas that are outside the box. KOTOBA JAM originally a chat bot system, generates completely unexpected neologism s by combining keyword s of the discussed subject with randomly picked modifiers from various designed modifier selections The system keep s mumbling phrases as an additional participant in brainstorming session s In this study, we focused on the effect of the neologisms , which created in the method of Text on the activity of idea creati on . T o increase the probability of inspiration, we designed the neologism generation system with a linguistic approach . We created a designed modifier database , which con sists of several types of modifiers based on Onomatopoeia, c artoon expression and the theory of inventive problem solving in engineering TRIZ . W e performed a u sability testing to observe users’ reactions to each neologism generated by KOTOBA JAM Then w e attempted to discover which types of modifiers increase the possibility of new ideas for products or services. During the usability testing , we discovered tendencies to create new ideas 1.The modifier s based on TRIZ functioned effectively as a trigger of new ideas for both designers and general users (non designers)designers). 2. Designers can be inspired even by a randomly selected modifier from a language dictionary. 3.Onomatopoeia was helpful for general users who ha d limited brainstorming experiences
