We're using these interactive name tags called nTAGS. These are little computers that you were around your neck. The goal is to provide a technology that enhances, rather than disrupts, face to face communication. The devices have a pretty simple interface and function well. They are a little heavy, but that's the first generation. I wish they were more dynamic. They're meant to be that, but the information that the conference attendees provided was more multiple choice than free form, so they're a little less free form than I think they need to be. Still its a fun experiment and they're great conversation starters.
