Disclosed is an autonomic alarm that adapts to a specific user?s behavior and schedule for the purposes of optimizing wake-up time and other event notification. The system considers the underlying semantic context of calendar events, historical user behavior, future events (and the importance of the same), and environmental conditions to determine an optimal alarm time.

Adaptive Alarm

Alarm clocks are simple devices that are programmed in advance to alert, awaken, or otherwise signal an event at a predetermined time or condition. Most are static in the sense that they generate a sound at the designated time and can be silenced (i.e., "snooze" function) for a brief period of fixed time.

Some alarms are smarter by sounding a louder or more urgent alarm if the user is not awake as determined by a motion sensor, or optimizing the wake-up time by analyzing the user's sleep cycle as determined by the user's micro-movements.

These traditional and smart alarm clocks do not consider external factors such as the effect of weather on travel time, the relative importance of an event, or the need to make slight wake-time adjustments for future events.

This invention describes an autonomic alarm that adapts to a specific user's behavior and schedule for the purposes of optimizing wake-up time and other event notification (e.g., when to leave for a meeting at another location). This solution is more effective than traditional alarm clocks that are programmed to alert the user at a predetermined time or at a predetermined interval before an event by being easier to use through autonomic configuration and adapting to the user's behavior and environment.

Prior Art
• Adaptive Alarm System. [1] The drawback of this system is that it is limited to single purpose (wake-up alarm) and cannot perform motion analysis outside the range of the motion detector.

• Holistic Alarm Monitoring. [2] The drawback of this invention is that it is described in the context of computer monitoring and suggests consolidating the user interface could be used for "trend analysis", but does not describe how the system could be used for calendar management or how trend analysis could be used for adapting the calendar.

The disclosed invention proposes the following in calculating an optimal alert time:
• Calendar: Current and near-future events are analyzed to determine lead-time or required adjustments in sleep patterns. For instance, if the user has a 9:00 AM meeting with a banking client, they may need extra time to dress in a suit prior to the meeting.

• Location & Movement: The user's geolocation is considered along with the calendar to understand potential travel time when moving from one destination to another. Movement time might be calculated using typical routing tools or the user's prior history for a given route. Location can also determine lead-time. For instance, if the user is in a hotel, more time might be allotted for breakfast.

• Environmental: Weather affects lead-time through traffic (e.g., slower, riskier driving in the rain) and through preparation activities (e.g., extra time to scrape frost off windshield). Traffic analysis, independent of weather conditions, is also an environmental condition.
