CrowdBarometer — bar density, capacity and agitation index
Feels when a bar crowd shifts from happy to about-to-fight.
Plausible physics, early work — shown honestly as an experiment.
How it works
The headcount comes from how much the room stirs the signal — that part is already well proven. Mood lives in the rhythm: relaxed people sway and gesture slowly, while shoving pushes fast, sharp motion into many links at once. When the whole room's rhythm speeds up together, the agitation index rises.
In the physics: Occupancy scales multipath variance (count r=0.9 proven). Crowd mood shifts the aggregate Doppler spectrum: relaxed socializing concentrates energy below ~2Hz (sway, gestures), while shoving/fight precursors push a measurable fraction of energy into 4-15Hz fast-limb bands and raise spectral entropy across many links simultaneously.

This is real pipeline output for Hospitality, replayed. The exact reading depends on your room.

How the field becomes an answer
How we prove it
WiMANS multi-person for density; own staged-scenario nights in a partner bar (choreographed shove/rush drills vs normal service) scoring alarm lead time vs incident logs.
Who it is for
Door-count compliance plus a 90-seconds-early heads-up for security — sold to the venue operator and their liability insurer, no cameras over the dance floor.
