Relationship Between Difference of Motivation and Behavior Change Caused by Visualization

Abstract

This study aims to verify the hypothesis that altruism makes others change their behavior. We developed an original system and application which collect global positioning system (GPS) data add photos on the maps and share them between subjects. We prepared two maps which are intended to contribute information by different motivations. The first map aims to develop a recommended course for a walk, focusing on subjects’ desire for recognition as the selfish motivation. The second map is aimed at safety for children, focusing on subjects’ altruism. Subjects can take pictures and upload them with an icon that they designate as the category; they are then shared among the subjects. If a subject sympathizes with the posted pictures, he/she can express approval on the picture. The results show that the map of safety for children has more pictures with multiple approvals, and some pictures on the map of recommended course for a walk have no approval. This suggests that the difference in motivation makes subjects express more approvals. With statistical analysis, we try to show that some type of visualization of GPS data may become a nudge.
