HBL Sky Graffiti Wall — Real-Time Co-Created AR Livestream Trophy

BRIEFING

Unable to attend games in person during the pandemic, fans found a new way to cheer — filling the sky above Taipei Arena with support using real-time AR streaming. Anyone, anywhere could point their phone at the sky and draw a message of encouragement for their team; a 24-hour livestream from Taipei Arena showed everyone's graffiti appearing in real time, blurring the line between real and virtual into one shared, immersive moment. Built as a real-time interactive web page tied to the phone's gyroscope, fans aimed their phone at the sky to draw their wish. Once submitted, it jumped straight into a live YouTube stream showing the AR composite over Taipei Arena — each individual wish coming together to form one giant championship trophy in the sky.
