First scale validation with 100+ simultaneous smartphones in a live setting. The
goal: confirm that the pipeline stays stable with larger groups.

Context of the event
During this live demo at Howest, Lumicrowd was tested in a larger hall setup
with broad audience participation. The setup used a pre-built pixel mapping in
MagicQ event software.
The setup
Lighting control via MagicQ
DMX pipeline: DMX -> Lumicrowd -> smartphones
Real-time distribution via SSE to mobile web clients
What worked well
Scale validation at 100+ users
This event confirmed that the system stays stable with larger groups, not only in small pilots.
Synchronisation quality
Differences between smartphones were minimal and visually acceptable at room level.
Fast adoption
Participants understood the flow quickly and could join the live show with little friction.
Challenges and insights
1) Network and device variation
A few devices visibly lagged behind, likely due to mobile data or device differences.
2) Sharper metrics logging
Exact active counts and peaks should be logged automatically per event.
Quote
"From 100+ users on, it really comes alive."
Conclusion and next steps
The core architecture stayed stable under load. The next priority is growing to
300-500 simultaneous participants, with stronger event logging and additional
network stress tests.
