A micro box links quiz play to campus screens
An event activation synchronised live smartphones and TV screens across campuses.
The project
For its university campus tour, Bouygues deployed an interactive multiplayer quiz on smartphones and a large display. The technical challenge lay in the live synchronization of 4G-connected phones with the display and a physical hardware unit. The studio engineered a web application using WebSockets, simultaneously connecting mobile players, the TV screen, and the control room. This contest ran across every tour date, capturing qualified contact information from students.

The challenge
The audience plays using their own mobile connection while a screen broadcasts the game. The system had to maintain immediate two-way synchronization between phones, the central display, and the physical trigger. The slightest latency on campus broke the competition and engagement in the contest.
Our approach
We developed a download-free web app, accessible via QR code. Participants join the game on their smartphones, and their answers appear instantly on the big screen via WebSockets. The host manages sessions from a dedicated console. During an instant-win moment, the server directly controls a physical unit on the booth. Behind the scenes, a back office centralizes game statistics, broadcasts the standby video, and exports the collected data.
