It’s another project to come out of MIT’s Media Lab for a spring event this year by [Rob, Dan & Javier]. The facial tracking software was re-used from an older project, the MIT Mood Meter, which was a clever installation that had several zones on campus tracking the apparent “happiness” of the students walking by.

While the Happiness Hat seems to work for treating the outward symptoms of unhappiness, this is but an early step towards the droud.
