Smart Badges Track Human Behavior

TechReview has posted recently on 'Smart Badges Track Human Behavior' which discusses how MIT researchers used conference badges to collect data on people's interactions to help visualize their social network:

New research from MIT's Media Lab has shown that a sensor-laden conference badge might be able to help people venture out, form new connections, and gain insight into how they interact with others at such events.

Ben Waber, an MIT researcher who worked on the project (and blogged about it here), gave souped-up badges to 70 participants at a Media Lab event. These badges use an infrared sensor to gather data about face-to-face interactions, a wireless radio to collect data regarding proximity to other badges and send it to a central computer, an accelerometer to track motion of the participant, and a microphone to monitor speech patterns. At the event, the data from the infrared sensors was wirelessly transmitted to a computer that crunched the numbers, producing a real-time visualization of the event's social graph.
