Happiness Machine was the latest member of Aaron Marcus' collection of Machine apps. Together with Green Machine and Health Machine, Happiness Machine aimed to help people live a better life in an appealing way.
Given a one week session, we were asked to choose to work on the dashboard (Happy Wall) or journaling (Happy Journal). Journaling encouraged people to take notes about cheerful things happened everyday and is the key activity of the app.
So instead of making journaling an assignment, our concept tracked users through their voice, photos and social networks. We believed that users will notice details they ignored better by seeing their moods recorded when they were not paying attention. And this would empower people to discover "just another day" was actually more memorable than they realized.
