Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Intended capability
Evaluate the sensing evidence for “Caregiver Presence & Interaction Verification” in a consented study using staged events and independent reference observations. This is not a care decision, fall prediction, emergency response, or proof of resident safety.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class A, and a catalog mapping or recording is not proof of this outcome at a real site.
Solution blueprint
See the environment before installing it.
This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording
A related Elderly scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Two bodies create separable RTI attenuation blobs and additive Doppler energy; occupancy counting at r=0.9 is proven. Assisted-transfer events (two tracks converging at bed/chair followed by a coordinated vertical-velocity chirp) have a distinct joint micro-Doppler signature versus two people in separate rooms.
02 Shared processing path
Occupancy count time series -> RTI multi-blob tracking for co-location distance -> joint micro-Doppler transfer-event detector -> per-visit interaction summary; MVE flags visits that deviate from the care-plan template.
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
Occupancy r=0.9 proven; WiMANS multi-person dataset for two-person separation; own pilot against agency electronic-visit-verification (EVV) logs in 15 homes.
04 Commercial hypothesis
For home-care agency owners and payers: 'EVV that can't be gamed from the driveway — physics-verified visit duration and actual hands-on interaction, no clock-in app.'
