An alert is used to inform a user that their blood glucose level has dropped below a threshold (e.g., the user is hypoglycemic) or has increased above a threshold (e.g., the user is hyperglycemic). There is a hierarchy of alerts from lowest priority to highest priority. The alert is communicated by a user device (e.g., a mobile device), which is, for example, a smartphone, smart watch, home automation device, or the like. The alert is modified in order to increase the likelihood that the user receives or acknowledges the alert within a minimal amount of time. An intensity level (e.g., a volume) of an alert is modified based on, for example, whether the user has acknowledged a previous alert. A modality or a sensory channel of an alert is changed if an initial alert does fails to elicit a response from the user.

A user terminal (10) according to one embodiment includes: a notification unit (11) configured to perform a notification for the user using at least one of a sound or a vibration; and a control unit (14) configured to control operations of the notification unit (11). The control unit (14) causes the notification unit (11) to execute a dummy notification not including details of which the user is to be notified at a predetermined notification timing separately from a regular notification including details of which the user is to be notified. The notification unit (11) sets a sound level or a vibration intensity of the dummy notification to be lower than a sound level or a vibration intensity of the regular notification.

Embodiments of the present invention relate to a wireless emergency bell and a method for controlling a wireless emergency bell installed in a school and a school zone, the method comprising the steps of: receiving an input signal generated by pressing a provided button by a reporter when an emergency situation occurs; generating an emergency bell signal, repeatedly transmitting the generated emergency bell signal to at least one pager and a receiver during a predetermined configuration time, and outputting a prestored alarm sound to the outside through a provided speaker; generating an emergency bell voice signal and transmitting the generated emergency bell voice signal to the at least one pager and the receiver; generating an emergency bell voice transmission completion signal indicating that the emergency bell voice signal has been completely transmitted, and transmitting the generated emergency bell voice transmission completion signal to the at least one pager and the receiver; converting an operation of the wireless emergency bell into a reception mode in which data can be automatically received from at least one pager after a configured time; receiving a pager voice signal from the at least one pager; determining whether the received pager voice signal exists, and outputting the received pager voice signal to the outside through the speaker when the received pager voice signal exists; and determining whether a mode conversion command signal is received from the at least one pager when the received pager voice signal does not exist, and converting the operation of the wireless emergency bell into a transmission mode in which data can b e transmitted to the at least one pager and the receiver when there is the received mode conversion command signal.
