A system is provided for establishing a compliance zone and monitoring interactions therewith. The system includes a compliance zone designator and a wearable device. The compliance zone designator transmits an ultrasound signal to establish the compliance zone. The ultrasound signal may be encoded with information on the compliance zone. The compliance zone designator is configured for placement at a location in which the compliance zone is desired. The wearable device is separate from the compliance zone designator. The wearable device includes a compliance zone recognition component configured to recognize the compliance zone and identify one or more pre-defined interaction criteria for the compliance zone. When the wearable device is within the compliance zone, the compliance zone recognition component recognizes the compliance zone and identifies the interaction criteria of the compliance zone. Based on the interaction criteria the wearable device determines and records compliance with the interaction criteria. The recorded data is optionally used to set off real-time alerts. The recorded data is also optionally used in subsequent analysis and documentation of compliance with protocols.
