That sounds like a fun puzzle. First, you’d need a low‑latency AR system that can track each model in real time, so the digital overlays stay aligned even when they’re moving fast down the catwalk. Using lightweight body‑sized motion capture suits or markerless computer vision would keep the setup clean. For the glow, I’d layer subtle LED strips or flexible OLED panels into the outfits. Those can change color or pulse in sync with the music, giving a physical glow that the AR app can augment with extra light effects or holographic textures. The AR app could project moving patterns over the models—think dynamic patterns that ripple as they walk, or even let the audience use their phones to choose which pattern to apply, so the crowd feels part of the show. To keep people hooked, incorporate real‑time data from the crowd’s phones—like a simple voting system or a touch‑based game where the audience can influence the light intensity or trigger a short visual flourish. That interactivity keeps the energy high and makes the experience feel personalized. The trick is to keep the tech invisible; any lag or glitch breaks immersion, so you’ll need a robust server pipeline and fail‑safe fallback visuals. Also, test on a real runway before the event—nothing like a rehearsal with actual models to iron out the physics of motion and lighting. I’d say the best AR runway is one that feels like a living, breathing canvas, not a gimmick.
