Abstract
The purpose of this research is to map and analyze impressions experienced by visitors to the zoo. So we focused on using color density. In the experiment, we used three color sticky notes, and had them write down the impressions experienced at the zoo. We attached the sticky note to the corresponding position on the zoo map and analyzed it from the color density. As a result, we found out that there is a difference depending on "the season " and "the number of times". By using this analysis method, we can expect to be able to analyze the impression of visitors diversely.
