Mood Meter: Large-Scale and Long-Term Smile Monitoring System

Los Angeles Convention Center, Concourse Foyer

Have you ever wondered whether it’s possible to quantitatively measure how friendly or welcoming a community is? Or imagined which parts of the community are happier than others?

Mood Meter is a computer-vision-based system that automatically encourages, recognizes, and counts smiles of a large environment or a community. The system was installed on a college campus during a 10-week festival to count smiles at four key locations. It collected and aggregated anonymous information, and then displayed the information in real time in various intuitive and interactive formats on a public web site, depicting the emotional footprint of the community as a function of smiles at any point in time.
