The project
For Meetic at Printemps Haussmann, an interactive booth connects singles through voice messages and photographic portraits. The system had to operate continuously within the department store without relying on internet network stability. The installation combines two synchronized screens, controlled dynamic lighting, and a local database ensuring offline functionality. Each participant records up to twenty seconds of audio and unlocks the photos only after listening to the messages in full. Successfully validated during the opening night, the booth continued its autonomous operation on the retail floor.

The challenge
The setup had to keep up with the pace of a crowded launch party, then operate autonomously in-store for weeks. The slightest network outage threatened to interrupt recordings. It was necessary to capture voice, take portraits, and synchronize profiles without blocking access or relying on a permanent connection.
Our approach
We designed the booth as an autonomous airlock. Inside, a touchscreen guides the visitor: a 20-second voice recording and photo shoot. To preserve the sense of discovery, the portrait remains blurred until the voice message has been listened to. Outside, a second synchronized screen broadcasts the experience to passersby while the lighting adjusts in real time. Under the hood, we built a resilient local architecture: the kiosk stores everything locally before asynchronously syncing streams to the cloud, ensuring continuous operation even offline.
Results
The system passed its trial by fire during the Meetic launch event without any incidents. The installation then transitioned to continuous autonomous operation within the Printemps Haussmann retail space, validating the booth's technical resilience in front of the public.
