Method and system for presence detection
Techniques for detecting and presenting rewards for presence are disclosed. Presence of a mobile device within a building is detected based on a plurality of triggers including a degradation of a first signal and a concurrent improvement of a second signal. The triggers are identified by a client-side application of the mobile device or a corresponding server-side processor with which the client-side application is in communication and from which the client-side application is configured to automatically receive available rewards. In response to detecting presence within the building, the server-side processor determines that a user of the mobile device is eligible for a reward, and the reward is provided to the user via the client-side application at the mobile device.
1. A method, comprising:
detecting presence of a mobile device within a building based on a plurality of triggers including a degradation of a first signal and a concurrent improvement of a second signal, wherein the triggers are identified by at least one of a client-side application of the mobile device and a corresponding server-side processor with which the client-side application is in communication;
determining at the server-side processor that a user of the mobile device is eligible for a reward for presence within the building; and
providing the reward to the user via the client-side application at the mobile device, wherein the client-side application at the mobile device is configured to automatically receive available rewards from the server-side processor.
2. The method of claim 1 , wherein the client-side application comprises a rewards service.
3. The method of claim 1 , wherein the plurality of triggers includes last known location data of the mobile device indicating proximity to the building.
4. The method of claim 1 , wherein the first signal indicates location data accuracy.
5. The method of claim 1 , wherein the first signal comprises a global positioning system (GPS) signal.
6. The method of claim 1 , wherein the second signal comprises at least one of a signal transmitted by a transmitter in the building and a beacon in the building.
7. The method of claim 1 , wherein the second signal encodes an identifier used for presence detection.
8. The method of claim 1 , wherein the second signal comprises a sound signal.
9. The method of claim 1 , wherein the second signal comprises a WiFi signal.
10. The method of claim 1 , wherein the second signal comprises a Bluetooth signal.
11. The method of claim 1 , wherein the second signal comprises a cellular signal.
12. The method of claim 1 , wherein the second signal comprises a radio frequency (RF) signal.
13. The method of claim 1 , wherein the second signal comprises a magnetic field signal.
14. The method of claim 1 , wherein the second signal comprises at least one of a LAN (local area network) and PAN (personal area network) signal.
15. The method of claim 1 , wherein the plurality of triggers includes detecting a change in acoustic properties.
16. The method of claim 1 , wherein the plurality of triggers includes detecting a barcode.
17. The method of claim 1 , wherein the plurality of triggers includes recognition of an identifier of the mobile device.
18. The method of claim 1 , wherein the plurality of triggers includes signals from at least one of an accelerometer of the mobile device and a compass of the mobile device.
19. A system, comprising:
a server-side processor configured to:
detect presence of a mobile device within a building based on a plurality of triggers including a degradation of a first signal and a concurrent improvement of a second signal, wherein the triggers are identified by at least one of a client-side application of the mobile device and the server-side processor with which the client-side application is in communication;
determine that a user of the mobile device is eligible for a reward for presence within the building; and
provide the reward to the user via the client-side application at the mobile device, wherein the client-side application at the mobile device is configured to automatically receive available rewards from the server-side processor; and a memory coupled to the server-side processor and configured to provide instructions to the server-side processor.
20. A computer program product embodied in a non-transitory computer usable storage medium and comprising computer instructions for:
detecting presence of a mobile device within a building based on a plurality of triggers including a degradation of a first signal and a concurrent improvement of a second signal, wherein the triggers are identified by at least one of a client-side application of the mobile device and a corresponding server-side processor with which the client-side application is in communication;
determining at the server-side processor that a user of the mobile device is eligible for a reward for presence within the building; and
providing the reward to the user via the client-side application at the mobile device, wherein the client-side application at the mobile device is configured to automatically receive available rewards from the server-side processor.
