John Havens, founder of the H(app)athon Project, warms up the SB '13 crowd with a lively bit of blues harmonica before diving into his talk. H(app)athon is a project Havens created to “Give big data a direction and help people leverage the mobile sensors in their smartphones to identify what brings them meaning in their lives.” The ambitious project is preparing a smartphone app called “Personal Happiness Indicator,” which will aggregate survey responses and personal data and attempt to identify activities and organizations that might help people optimize their personal well being.
