We can direct users through a building to the least crowded destination using cues that indicate the next step in a path; providing next-step directions to users is a well-known technique. Often, the path planning is static, occurring before users start off to their destinations. This project will direct users through the Media Lab to specific destinations using real-time status information in an ad hoc network. We can infer the crowd size at locations such as demo areas using sensors. The sensors forward on that crowd data to nodes in hallways and doorways whose displays direct users to the least-crowded destination. As crowd sizes change, the nodes adapt and redirect users to different areas without any centralized control.
