At the end of April, I participated in a panel discussion of Gamification@Work at the CHI conference in Paris. The panel had a bunch of great folks--Mac Smith from Google, Janaki Kumar from SAP, Scott Schnars from Badgeville and Sebastien Deterding. There's a LinkedIn conversation with some of the questions and presentations here.
I noticed a lot of interest in anything related to game design or gamification at CHI this year. Our session was standing room only--the photo below was before we even started--it got more crowded into the actual session time. The questions were great and we even had a little debate about whether you could gamify something you cannot measure (I say no, but I also think there are plenty of things you can find a way to measure if you are determined to). It's encouraging to see so much interested in the area from Usability and Interaction Design professionals.
