PAX Mood Tracker

Mood Tracking PAX is a subdivision of the PAX app. This Android application is designed to study and compare various mood measures and interactive designs. It compares classical, chatbot, and graphical interfaces against various mood measures from the literature.

Although we designed this app for a scientific study, users have continued to use it by choice beyond the study duration. The study was announced to be for a maximum of two weeks. The app is still active, attracted more than 1000 users, and has users who have been using it for more than a year.

Interesting results emerged from this study. Beyond finding the best approach for mood tracking, we were able to come up with a short, new measure for mood tracking. Using collected data, we also investigated an adaptive measure that adapts its questions based on its prediction of the user’s mood.
