Nokia researcher Jan Chipchase investigates the ways we interact with technology — a quest that has led him from the villages of Uganda to the insides of our pockets. Along the way, he’s made some unexpected discoveries: about the ways illiterate people use their mobile phones, the new roles the mobile can play in global commerce, and the deep emotional bonds we share with our phones. And he’s got a surefire trick to keep you from misplacing your keys. (Recorded March 2007 in Monterey, California. Duration: 16:15.)
