Elderly Care Shared-family mapped

Who really came in

Front-Door Visitor Evidence Ledger

Opt-in doorway-event photo concept; schedule matching cannot identify or verify a caregiver.

Open demo room Design this solution See how it works

Readiness Shared-family mapped

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

Evidence Supported hypothesis

Published physics or adjacent results support the hypothesis; capability-specific product and site validation are still required.

Runtime family Presence

Calibrated motion and presence score from CSI variance and change statistics.

When no ESP32 is connected

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

Intended capability

Evaluate the sensing evidence for “Front-Door Visitor Evidence Ledger” 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 B, and a catalog mapping or recording is not proof of this outcome at a real site.

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

CSI link perturbation detects the door approach (proven presence physics); the XIAO Sense camera wakes only on that trigger, runs TFLite-Micro person detection on a QVGA frame, and commits a single bounded capture to local storage. No streaming representation exists in the blueprint language, so continuous video is structurally impossible, not merely disabled.

02 Shared processing path

CSI door-zone motion gate -> camera wake -> on-device person detect (TFLite-Micro) -> single bounded capture + timestamp -> local ledger reconciled against the scheduled-visit calendar

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

Door-mounted pilot: trigger precision/recall against a manual door log; person-detect false accepts (pets, packages); approach-to-stored-frame latency; storage audit proving zero frames exist outside trigger events.

04 Commercial hypothesis

'Who really came in' — for families and guardians verifying home-care visits at the door without ever putting a camera inside the home.
