Mood Estimation Method in a Group Using Smartwatches to Support Positive Tourism Experiences

This paper proposes a method of estimating a group’s mood based on the number of synchronicities of heart rate peaks in the group as a means to support positive tourism experiences. This study constructed a prototype system with a smartwatch and a smartphone and conducted a field experiment for 12 groups at nine points of interest in Kyoto City, Japan. The results of the investigation showed that the proposed method could estimate a group’s mood from the relationships between the psychometric evaluation of groups and their synchronized heart rate peaks.
