Method and system for embedded device localization-based progressive indicators

1. A method, executed in a processor of a server computing device, of locating an embedded device, the method comprising:

receiving at the server computing device, from a locator device, a request for locating the embedded device hosted within a host asset device, the server computing device being communicatively coupled to the embedded device and the locator device;

localizing the embedded device, based on fingerprint data of a pedestrian area and data received from the embedded device, the embedded device comprising the fingerprint data, wherein localization comprises a confidence level determined by fusing probabilistic results of multiple concurrent location estimates of the embedded device;

providing, to the locator device, localization results for showing a trajectory traversed by a user in possession of the locator device relative to the host asset device and the embedded device within the pedestrian area;

determining a proximity of the locator device relative to the embedded device; and

providing an input to operate at least one user interface indicator based on the proximity and the confidence level.

2. The method of claim 1 wherein the embedded device is one of removably and fixedly hosted within the host asset device.

3. The method of claim 1 wherein determining the proximity includes determining at least one of a distance and a direction of the embedded device relative to the locator device.

4. The method of claim 3 wherein the at least one indicator comprises at least one of an audible and a visible indicator at the host asset device.

5. The method of claim 4 further comprising varyingly operating the at least one indicator as the locator device advances in proximity to the embedded device.

6. The method of claim 1 wherein the localizing comprises location coordinate information and floor number information for the embedded device within a multi-floor building.

7. The method of claim 1 wherein the localizing is based on at least one of a magnetic field strength and direction, a received wireless communication signal strength, a wireless connectivity indication and a barometric pressure in accordance with the fingerprint data of a multi-floor building.

8. The method of claim 7 wherein the fingerprint data includes time-stamps whereby the magnetic field strength and direction, the received wireless signal strength, the wireless connectivity indication and the barometric pressure are time-correlated based on the time-stamps.

9. The method of claim 1 wherein the localizing comprises a coordinate location associated with a probabilistic estimate expressed as the confidence level.

10. The method of claim 9 further comprising operating the at least one user interface indicator only if the confidence level exceeds 70 percent.

11. A server computing system for locating an embedded device, the server computing system comprising:

a processor; and

a memory including instructions executable in the processor to:

receive, from a locator device, a request for locating the embedded device hosted within a host asset device, the server computing device being communicatively coupled to the embedded device and a locator device;
