The method includes associating an alarm device with the user's body by securing a wearable device to the user's wrist, placing the device in a pocket, integrating the device into the user's clothing such as a belt, or otherwise placing the device in contact with or adjacent to the user. The device includes one or more sensors for detecting physiological and/or environmental parameters such as heart, respiration, or pulse rate, body movements, eye movements, ambient light, and the like. If the user is asleep, the alarm is actuated in a typical manner. If the user is awake, the alarm is suppressed. If the user is neither asleep nor fully awake, the alarm is adjusted to provide an appropriate level of stimulation. ## Claims ### Claim 1 A method of controlling an alarm feature of a wearable device based on the sleep state of a user, the method comprising: sensing a physiological parameter of the user through a sensor associated with said wearable device; determining the sleep state of the user based on said physiological parameter; and actuating said alarm in accordance with said sleep state. ### Claim 2 (depends on 1) The method of claim 1, further comprising securing said device to the user's wrist using a wrist band. ### Claim 3 (depends on 1) The method of claim 1, wherein determining comprises monitoring physiological data associated with the user's sleep state. ### Claim 4 (depends on 3) The method of claim 3, wherein said physiological data comprises user limb movements. ### Claim 5 (depends on 3) The method of claim 3, wherein said physiological data comprises at least one of: galvanic skin response; pulse oxymetry data; heart rate; and respiration. ### Claim 6 (depends on 1) The method of claim 1, wherein actuating comprises actuating an alarm which is connected to and on-board said device. ### Claim 7 (depends on 1) The method of claim 1, wherein actuating comprises actuating an alarm which is remote from and off-board said device. ### Claim 8 (depends on 1) The method of claim 1, wherein sensing comprises recognizing a pattern associated with the user's eyes. ### Claim 9 (depends on 1) The method of claim 1, wherein said actuating is repeated at an increasing level of stimulation if the user remains asleep after an initial actuation. ### Claim 10 (depends on 8) The method of claim 8, wherein determining comprises determining whether the user's eyelids are closed. ### Claim 11 (depends on 1) The method of claim 1, wherein sensing comprises detecting nodding of the user's head. ### Claim 12 (depends on 3) The method of claim 3, wherein sensing comprises detecting the user's skin temperature. ### Claim 13 (depends on 1) The method of claim 1, wherein said alerting comprises at least one of: audible alarm; vibration; blinking LEDs; and displayed text. ### Claim 14 A method of controlling an alarm associated with a wearable device, the method comprising: monitoring a physiological parameter using a sensor associated with said device; detecting, using said sensor, the sleep state of the user; actuating said alarm if the user is asleep; dismissing said alarm if the user is awake; and modifying said alarm if the user is neither asleep nor fully awake. ### Claim 15 A wearable device for providing an alert to a user, the device comprising: a controller; a user interface coupled to said controller, wherein said user interface facilitates scheduling said alert for a user-selected point in time; a sensor coupled to said controller, wherein said sensor detects a sleep state of the user; wherein said controller is configured to: cause said alert to be provided to the user if the user is asleep at said point in time; and suppress said alert if the user is awake at said point in time. ### Claim 16 (depends on 15) The device of claim 15, wherein said sensor is configured to monitor a physiological parameter of the user associated with the user's sleep state. ### Claim 17 (depends on 15) The device of claim 15, wherein said sensor is configured to detect body movements. ### Claim 18 (depends on 16) The device of claim 16, wherein said sensor is an accelerometer. ### Claim 19 (depends on 18) The device of claim 18, wherein said accelerometer is configured to detect rhythmic bodily movements associated with heart rate. ### Claim 20 (depends on 18) The device of claim 18, wherein said accelerometer is configured to detect rhythmic bodily movements associated with respiration.
