Seulsoleil, Lighting Design


VISIBLE, a Slovenian creative technology company has completed an interactive lighting installation in Paris Expo Porte de Versailles. They worked with Seulsoleil, a lighting design agency based in Paris, who was responsible for lighting design.


The installation is positioned below a bridge on which the main Parisian ring road (Boulevard Périphérique) crosses Paris Expo. The traffic is monitored with 2 dedicated video cameras, which stream their video feeds to a LightAct media server. LightAct is continuously analysing the speed and density of the traffic and based on those it generates real-time patterns which are then mapped to the luminaires.


As part of the project, our studio developed a self-learning tracking algorithm that detects the type, position and velocity of vehicles on the road. This information is then used to generate real-time lighting patterns that were designed by Seulsoleil and VISIBLE. The project was completed on-time and on-budget which was only made possible by using LightAct, our own control system for interactive architecture.
