Abstract

A proximity based ad-hoc messaging, alerting, and tracking system can be employed to quickly and efficiently propagate alerts when a child or other individual becomes lost. Various types of alerts can be provided to facilitate locating a lost individual even in scenarios where a network connection or GPS is not available. The system can also be employed to track the presence of an individual after traveling in a vehicle to enable detecting when the individual has been separated from all guardians such as would be the case when the individual is left in the vehicle.

Claims

1. A method, performed by a user device, for implementing an alerting system, the method comprising:

monitoring for alerts that are transmitted using a short range wireless protocol;

receiving a first alert that includes an alert identifier that indicates that an individual is lost and an identifier of the lost individual;

generating and sending a second alert that includes an alert identifier that indicates that an individual is lost and the identifier of the lost individual; and

using the identifier of the lost individual to obtain and display information about the lost individual.

2. The method of claim 1, wherein the alert identifier included in the first alert indicates that the first alert was sent by an initiator user device and the alert identifier included in the second alert indicates that the second alert was not sent by the initiator user device.

3. The method of claim 1, wherein using the identifier of the lost individual to obtain information comprises sending the identifier of the lost individual to a server to obtain the information from the server.

4. The method of claim 1, wherein using the identifier of the lost individual to obtain information comprises identifying that the information was previously retrieved and stored on the user device.

5. The method of claim 1, further comprising:

storing the identifier of the lost individual in association with the alert identifier that indicates that an individual is lost.

6. The method of claim 5, further comprising:

receiving a third alert that includes an alert identifier that indicates that an individual is present within a proximity of the user device and an identifier of an individual;

comparing the identifier of the individual included in the third alert to the stored identifier of the lost individual; and

upon determining that the identifier of the individual included in the third alert matches the stored identifier of the lost individual, displaying an indication that the user device is within proximity of the lost individual.

7. The method of claim 6, wherein the indication includes an option to contact an initiator user device.

8. The method of claim 6, further comprising:

receiving a fourth alert that includes an alert identifier that indicates that a location is present within a proximity of the user device and an identifier of the location;

using the identifier of the location to obtain information about the location; and

displaying the information about the location in conjunction with the indication that the user device is within proximity of the lost individual.

9. The method of claim 8, wherein using the identifier of the location to obtain information about the location comprises one of:

sending the identifier of the location to a server to obtain the information about the location;

or

identifying that the information about the location was previously retrieved from the server and stored on the user device.

10. The method of claim 1, wherein the short range wireless protocol is Bluetooth Low Energy such that the alerts are in the form of Bluetooth Low Energy packets, and wherein the alert identifier that indicates that an individual is lost is stored in the proximity UUID field of an iBeacon packet contained within the Bluetooth Low Energy packet.

11. The method of claim 10, wherein the identifier of the lost individual is stored within the major and minor fields of the iBeacon packet.

12. The method of claim 1, further comprising:

receiving a third alert that includes an alert identifier that indicates that an individual is present within a proximity of the user device and an identifier of an individual;

comparing the identifier of the individual included in the third alert to the stored identifier of the lost individual; and

upon determining that the identifier of the individual included in the third alert does not match the stored identifier of the lost individual, storing the identifier of the individual included in the third alert in association with the alert identifier that indicates that an individual is present within a proximity of the user device.

13. One or more computer storage media storing computer-executable instructions which when executed on a user device implement a method comprising:

monitoring for alerts that are transmitted using a short range wireless protocol;

receiving a child lost alert that includes an identifier of a lost individual; and

generating and periodically sending a child lost forwarded alert that includes the identifier of the lost individual.

14. The computer storage media of claim 13, wherein the method further comprises:

receiving a child presence alert that includes an identifier of an individual; and

determining whether the identifier of the individual included in the child presence alert matches an identifier of a lost individual that was included in a previously received child lost alert.

15. The computer storage media of claim 14, wherein the child presence alert is received prior to the child lost alert, the method further comprising:

storing the identifier of the individual included in the child presence alert;

upon receiving the child lost alert, determining that the identifier of the lost individual matches the stored identifier of the individual; and

notifying a user of the user device that the user is within proximity of the lost individual.

16. The computer storage media of claim 14, wherein the child presence alert is received after the child lost alert, the method further comprising:

notifying a user of the user device that the user is within proximity of the lost individual.

17. A method, performed by a user device, for tracking an individual, the method comprising:

determining that the user device is traveling in a vehicle;

monitoring for presence alerts from other devices within proximity of the user device, each presence alert including an identifier of either a guardian or an individual for which the guardian is responsible;

in response to receiving presence alerts, compiling a list that includes the identifiers contained in the presence alerts, the list including an identifier of a child device and an identifier of another user device;

detecting that the user device is no longer traveling in the vehicle and, in response, sending the compiled list to a server;

continuing to monitor for presence alerts from the child device; and

upon ceasing to receive presence alerts from the child device, notifying the server that the user device is no longer receiving presence alerts from the child device.

18. The method of claim 17, further comprising:

receiving a notification from the server indicating that the other user device is also no longer receiving presence alerts from the child device.

19. The method of claim 17, further comprising:

commencing to again receive presence alerts from the child device; and

notifying the server that the user device is again receiving presence alerts from the child device.

20. The method of claim 17, wherein determining that the user device is traveling in a vehicle comprises:

receiving location alerts from a location device contained in the vehicle; and

receiving accelerometer data indicating that the user device is moving.
