Abstract
In this paper, we propose a method for quantitative prediction of the effect of Shikake. In the current Shikake case study, designers design shikakes based on empirical knowledge and rules of thumb and analyze the effects from the feedback. In this study, we focused on a type of Shikake that encourages thinking bias by presenting keywords. The proposed method compares a participant’s answer for a keyword and the content of text data that can be collected from the web.
