In a personal emergency response system (PERS), a subscriber wears a personal help button (PHB) () with a call button (). A speakerphone console () detects a signal transmitted by the PHB when the call button is pressed and establishes a telephone call with a PERS center (). The PHB, speakerphone console, or combination thereof also performs a check-in process including: detecting () a check-in time and outputting () a request to perform a check-in action and detecting () whether the check-in action is performed. The check-in action is logged () if it is detected. A remedial action () is performed if the check-in action is not detected. The check-in action may be a designated motion of the PHB detected by gesture recognition algorithm performed by the PHB that analyzes sensor data generated by a motion sensor () of the PHB.

Check-in service on a personal help button

In a personal emergency response system (PERS), a personal help button (PHB) () includes a call button (), a motion sensor (), and a transmitter or transceiver () for transmitting a wireless call signal responsive to pressing the call button. An electronic processor () performs a compliance monitoring process () at successive compliance check times, each including: acquiring motion sensor data over a compliance data acquisition time interval; determining whether the PHB has moved since the last compliance check time; and assessing compliance based at least in part on the determination of whether the PHB has moved. The determining may include determining an orientation change of the PHB since the last check time. Alternatively, compliance may be monitored by detecting and logging wake-up interrupt events that cause the motion sensor to switch from a low-power mode to an operational mode.
