At a 50,000-seat stadium, you have roughly 15 minutes between gates opening and kick-off to get a significant fraction of the crowd connected to a display system. That's not much time. Every extra step in the onboarding flow, every redirect, every permission request, every moment of confusion, drops a percentage point off your participation rate. The design of the fan-facing interface is not a secondary concern. It determines whether the effect you spent hours building actually fires across a full house.
No app download is the single biggest design decision
Requiring fans to download an app is a participation killer. The friction is compounded at events: people are in a social context, distracted, often unfamiliar with the venue's WiFi, and not in the mindset to install software. Browser-based systems sidestep this entirely. A fan visits a URL (printed on the ticket, displayed on the scoreboard, announced over PA) and the interface loads immediately. No install, no account creation, no permission hoops beyond what the browser already handles.
Seatwave's architecture is built on this principle. The entire fan experience lives in the browser. WebSocket connections handle the real-time communication. There is nothing to download.
Seat number entry is the critical UX moment
After loading the URL, fans enter their seat number. This is the highest-friction moment in the flow. Seat numbers come in many formats (A12, 15B, S1-A12, Block 7 Row C Seat 21), and the input needs to accept them all without making fans guess which format to use. The system should surface the format on the ticket QR code or via a simple example so fans know exactly what to type. Auto-formatting and liberal matching (ignoring spaces, accepting upper and lower case) reduce entry errors significantly.
Browser permissions: keeping them minimal
The phone screen requires no special browser permissions. The flashlight requires camera access, a permission prompt that some users decline or dismiss. The onboarding flow should present this permission request with clear, plain-language context: "To turn on your phone torch for the light show, tap Allow." Done correctly, permission acceptance rates are high. Done poorly (a bare browser prompt with no explanation), they're not.
The design principle here is consent with context. The fan knows what they're agreeing to and why. That transparency also reflects well on the event brand.
The confirmation moment matters
Once a fan has joined and their seat appears on the admin dashboard's live 2D map, the fan-facing interface should confirm it visually. A brief colour flash or a "You're in!" message tells the fan the system is working. This is important because the next effect may not fire for several minutes. Without confirmation, fans who successfully joined will sometimes assume it didn't work and disengage. A confident confirmation state keeps them in the experience.
What the admin sees in real time
From the operator side, the admin dashboard shows a live 2D seat map updating as fans join. Each connected seat is marked. This lets operators see coverage patterns before an effect fires, useful for deciding whether to hold a trigger until coverage in a specific section improves. The real-time map also catches configuration errors early: if a section shows no connections when the area is clearly occupied, there's likely a seat map or URL issue to resolve before the show starts.
Fan participation is not guaranteed by having good technology. It's earned by removing every unnecessary barrier between a fan and the light show. The onboarding flow is where that work happens, and every second it saves pays back in fuller, more impressive effects across the stadium.
