A photo booth extracts visitors in real time
An interactive in-store installation streams live video across two large vertical touchscreens.
The project
Two interactive photobooth kiosks equip OPPO retail spaces in two Parisian FNAC stores. The installation had to ensure live video background removal without relying on the store's network connection. Each kiosk combines a large-format touchscreen with local green-screen processing powered by Node.js. The system stores usage statistics offline and resets after 30 seconds of inactivity. The same team developed the software and deployed the installation across both sites.

The challenge
The installation had to run uninterrupted amid shopper traffic. Two critical issues threatened the operation: the latency of live background removal and the frequent instability of the in-store wireless network. The system had to remain fluid, perform keying instantly, and continue functioning even during extended connection outages.
Our approach
We designed an interactive installation built around vertical touchscreens and a smartphone-based mobile capture application. In front of the screen, an idle loop invites passersby. As soon as someone approaches, the application frames their portrait and triggers a countdown. A local server processes the chromakey cutout in real time, without relying on an external 3D engine, and then streams the video feed back to the kiosk. Once the photo is confirmed, the user retrieves it on a dedicated web platform. An administration dashboard centralizes the data and handles automated exports of usage statistics.
