A sprint track triggers a giant LED wall
An interactive event installation measures visitor sprints using laser sensors and giant display screens.

The project
At the Xbox booth at Paris Games Week, an interactive installation timed visitors in a sprint challenge. The system required real-time synchronization between physical sensor signals and video broadcast. The team designed a photo registration kiosk, a running track, and two laser sensors. A ten-by-two-meter LED wall projected the dynamic race against virtual athletes. The installation compared lap times and instantly generated a results QR code for each runner.

The challenge
Having the public race in real time requires absolute precision. The slightest delay between physical action and broadcasting breaks the credibility of the duel. Our challenge: synchronize the track crossing sensors, video capture, and display on a ten-meter by two-meter screen live.
Our approach
The visitor starts at a podium kiosk: entering their nickname, legal confirmation, and webcam photo. Right from the start on the carpet, two laser and infrared sensors connected to a microcomputer measure the run live. On the LED wall, animations and the virtual race activate to compare strides. At the finish line, the interactive installation displays the score with a personalized QR code to take away their result, before returning to an idle video.
