Rafael Lozano-Hemmer, “Pulse Corniche,” 2015

"Pulse Corniche" was an interactive canopy of powerful light beams projected into to the sky by robotic searchlights whose brightness and orientation was controlled by the heart-rate of visitors to the Abu Dhabi’s Corniche. People were free to participate by holding a sensor placed in the centre of the plaza that converted the electrical activity of their heart into a unique lighting sequence. The intensity and direction of the lights visualized the different biometric rhythms of each participant, in an urban scale, transforming the public space into a fleeting architecture of light and movement. When no one was participating, the matrix of lights showed the heart beat recordings of the last 5 people who tried the interface.
