In this design project, I focused on promoting non-verbal interactions among passengers while envisioning the subway car as a human body system. I studied relationships between people in the subway car  and wanted to find out how to design a public space environment to make people be aware of one another. The goal is to promote the emergence of collective interconnections among people in a physically confined environment.

I imaged that a subway car is like a human body system -- it has the heart beat, the body temporatory, and can breath as well. Inspired by this idea, I designed an interactive subway car. When passengers were standing inside and holding the same pole together while travelling, the pole could collect their heard beats and body temporatures, and showed an average heard beat and body temporatore in a led display. Hence, passengers could see the result of their collective behaviors and feel that they are interconnected.
