Original Idea¶
Video-based monitoring of lab technicians to enforce hand-washing between instrument pickups. Real-time alarm on violation. Video evidence for escalation.
Reframe Accepted¶
- Instrument pickup detection → RFID/NFC tags on instruments
- Hand-wash detection → soap dispenser or sink flow sensor
- Video feed → passive recorder; clipped and attached to violation alerts only
Assumptions at Premise Stage¶
| Assumption | Status | Why |
|---|---|---|
| RFID can reliably detect instrument pickup in lab environment | Solid (reframe) | Passive UHF RFID at bench-level is well-proven; on-metal tags resolve metal body interference |
| Sink/soap sensor can reliably detect hand-wash events | Solid (reframe) | Binary sensor on soap pump or flow sensor on tap; near-100% reliability |
| Protocol rule maps to a state machine | Solid | pick-up A → must wash → pick-up B is a deterministic sequence |
| Real-time alerting is feasible | Solid (reframe) | Sensor events are near-instantaneous; no heavy CV inference in the critical path |
| Multi-person attribution is manageable | Questionable | Requires person-ID (badge RFID, wristband, or camera-based face ID) to distinguish which technician picked up which instrument |
