In this study, we focused on the presented information that influences idea generation at the “idea generation stage,” and aimed to clarify the influence that differences in the quality of expression and amount of information in the presented information have on idea generation. The research methods included the creation of five experimental stimulus videos of varying quality and the operation of an online idea generation workshop for the purpose of evaluating the experimental stimuli. The data obtained was analyzed by evaluating ideas, evaluating impressions of videos, and text mining of speech data from interviews. We have shown as a guideline the influence that five types of presented information with different quality of expression have on idea generation in terms of amount of ideas, creative leaps, quality of ideas, satisfaction level, and concrete improvement. The following conclusions were obtained: “Kamishibai videos have the effect of stimulating ideas,” “Line drawing videos have the effect of improving the quality of ideas,” and “2D videos have the effect of increasing the desire to come up with new ideas.”
