Hospitality & Retail Shared-family mapped

CrowdCalm

CrowdBarometer — bar density, capacity and agitation index

Research concept for crowd-motion intensity; it cannot infer emotion, intent, or an imminent fight.

Readiness Shared-family mapped

Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.

Evidence Unvalidated concept

An early research proposal with no capability-specific product validation yet.

Runtime family Occupancy estimate

Coarse occupancy estimate from calibrated multi-link field activity.

When no ESP32 is connected

No compatible ESP32 stream is connected. Use the bundled Hospitality recording; it demonstrates the shared Occupancy estimate runtime, not independent proof of this capability.

Intended capability

Pilot this intended outcome through the shared Occupancy estimate family, then validate it against site-specific ground truth: Live venue occupancy against licensed capacity, zone-level crowding, and an early-warning 'agitation index' when aggregate crowd motion shifts from social to volatile.

This describes the intended outcome. Readiness is shared-family mapped, evidence is class C, and a catalog mapping or recording is not proof of this outcome at a real site.

Bundled recording

A related Hospitality scene

This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.

01 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.

02 Shared processing path

Occupancy regressor per zone -> aggregate micro-Doppler spectral-shape features (band ratios, entropy) -> adaptive PCA + MVE manifold with rolling per-night baseline so 'busy Saturday normal' doesn't alarm, but coordinated fast-motion deviation does.

This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.

03 Validation plan

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.

04 Commercial hypothesis

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.
