  • Publication number: 20240122554
    Abstract: The present invention relates to a method for generating an alarm pertaining to continuous biometric data and, more specifically, to an alarm generation method in which, if an alarm condition is satisfied, an alarm is output to a user while maintaining the alarm in an activated state during a set alarm period, and changing the alarm type selected by the user during the alarm period, thereby enabling the user to be prompted to input information or take an action in response to the alarm without ignoring the alarm, while not causing inconvenience to the user due to frequent alarms; and when the alarm condition is satisfied, an operating mode of a receiver is determined and the alarm type, which has been set in accordance with the alarm condition, is changed to an alarm type corresponding to the operating mode of the receiver, thereby making it possible to prevent an alarm from being generated against the user's wishes.
