Abstract
We explore possibilities for applying wireless sensor networks (WSN) in interactive art. One Million Heartbeats, our interactive artwork, uses a ZigBee wireless sensor network, bio-feedback sensors, video projection, sculpture, and a weblog. It depicts the struggle between twin fetuses in the "world" of a mother's womb, and many people interpret it as commentary on political or social events. We will collect one million "heartbeats" from participants - the behaviors of our participants determine the characteristics of the fetuses and the experience of the mother. Participant comments become part of the piece. This artwork explores collective social behavior. We believe that this piece shows a new medium for interactive art: ubiquitous wireless sensor networks.
