Abstract

According to one embodiment of the present invention, a method for identifying the occurrence of an event from sensor data streams may be provided. The method may include accessing a plurality of sensor data streams generated by a plurality of sensor sets. Each sensor set may comprise one or more sensors. A sensor data stream may be associated with a user. The user may be co-located with a sensor set that generates the sensor data stream. A relationship between two or more sensor data streams of the plurality of sensor data streams may be identified. The method may further include determining, according to the relationship, that the plurality of sensor data streams corresponds to an event. A notification of an occurrence of the event may be sent.

Claims

1. A method comprising:

receiving a plurality of sensor data streams generated by a plurality of sensor sets, each sensor set comprising one or more sensors, a sensor data stream associated with a user co-located with a sensor set that generates the sensor data stream;

identifying a relationship between two or more sensor data streams of the plurality of sensor data streams;

determining, according to the relationship, that the plurality of sensor data streams correspond to an occurrence of an event; and

sending a notification of the occurrence of the event.

2. The method of claim 1, the determining, according to the relationship, that the plurality of sensor data streams correspond to an occurrence of an event further comprising:

accessing a collection of events, each event associated with one or more sensor value ranges; and

identifying the event from the collection of events according to a second relationship between one or more sensor data streams of the plurality of sensor data streams and the one or more sensor value ranges associated with the event.

3. The method of claim 1, the determining, according to the relationship, that the plurality of sensor data streams correspond to an occurrence of an event further comprising:

accessing metadata that describes a sensor data stream of the plurality of sensor data streams; and

identifying the event according to the metadata.

4. The method of claim 1, further comprising:

accessing metadata that describes a sensor data stream of the plurality of sensor data streams; and

updating a collection of events according to the metadata and the sensor data stream.

5. The method of claim 1, further comprising:

receiving a response indicating whether the event accurately describes one or more sensor data streams of the plurality of sensor data streams; and

updating a collection of events according to the response.

6. The method of claim 1, the plurality of sensor data streams communicating a location of a user.

7. The method of claim 1, the plurality of sensor data streams communicating biometric data of a user.

8. The method of claim 1, the plurality of sensor data streams communicating environmental data associated with a user.

9. The method of claim 1, the plurality of sensor data streams communicating a behavior of a user.

10. One or more tangible non-transitory computer-readable media having computer-executable code, when executed by a computer operable to:
