Information System for Estimating People's Mood at Sightseeing using Their Pulses Information

We can enjoy sightseeing more by communicating with friends. Communication with friends is about sightseeing spots. Recently, we can get information of sightseeing spots from a trip guide system through a smartphone or tablet. However, these systems provide information even in unnecessary situations, which may interfere with sightseeing. So, we proposed ways to estimate the mood of tourists using wearable devices. This paper describes the usefulness of information systems and systems developed based on that method. This information system detects an excitement degree of the party in a place through by using a pulse rate of all tourists which are collected by the Apple Watch. And it offers the information of spot for changing the mood of the party when they are not enjoying sightseeing. In the evaluation experiment of three group, this information system has been found to be useful. However, the experiment result shows that information service in this time to the members to shift their emotions to positive is not effective. In the future, it is necessary to consider how to provide and contents.
