Adaptive wearable device for controlling an alarm based on user sleep state

A method comprising:

• determining, at a user-selected point in time and based on at least one physiological parameter detected by a sensor coupled to a wearable device, a sleep state of a user of the wearable device;
• responsive to determining, based on the sleep state, that the user is currently asleep:
• actuating the alarm;
• and
• responsive to determining that the user has not acknowledged the alarm within a predetermined time period, outputting two or more alerts in which each respective successive alert of the two or more alerts has at least one of a greater amplitude, frequency, or duration than each respective prior alert of the two or more alerts, wherein the two or more alerts are output until the user has acknowledged at least one of the two or more alerts;
• and
• responsive to determining, based on the sleep state, that the user is currently awake, suppressing actuation of the alarm.

A device comprising:

• a controller;
• a sensor coupled to the controller, wherein the sensor detects at least one physiological parameter of a user;
• wherein the controller is configured to:
• determine, at a user-selected point in time and based on the at least one physiological parameter of the user, the sleep state of the user;
• and
• responsive to determining, based on the sleep state, that the user is currently asleep:
• actuate the alarm;
• and
• responsive to determining that the user has not acknowledged the alarm within a predetermined time period, output two or more alerts in which each respective successive alert of the two or more alerts has at least one of a greater amplitude, frequency, or duration than each respective prior alert of the two or more alerts, wherein the two or more alerts are output until the user has acknowledged at least one of the two or more alerts.
