Pulse Front

Relational Architecture 12

“Pulse Front” (Relational Architecture 12) was a matrix of light over Toronto's Harbourfront, made with lightbeams from twenty powerful robotic searchlights, entirely controlled by a network of sensors that measured the heart rate of passers-by. Ten metal sculptures detected the pulse of people who held them: the readings were immediately converted into light pulses by the computers and also determined the orientation of the beams. The resulting effect was a visualization of vital signs, arguably our most symbolic biometric, at an immense scale and in an urban setting. When no one was participating, the light matrix showed the heart rate recordings of the previous 10 participants.
