Abstract

A method (400, 500) of identifying a route traveled. The method can include, while traveling away from an initial location (115), detecting a unique identifier for each of a plurality of wireless communication devices (125) along the route. The method also can include presenting an indicator (210) that indicates a relative distance from at least one of the wireless communication devices while traveling toward the initial location. Detecting the unique identifier for each of the plurality of wireless communication devices can include detecting a media access control (MAC) identifier or an Internet protocol (IP) address for at least one of the communication devices.

Claims

1. A method of identifying a route traveled, comprising:

while traveling away from an initial location, via a processor, detecting a unique identifier for each of a plurality of wireless communication devices along the route, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting at least one of the unique identifiers from a wireless communication device within a parked vehicle passed while traveling away from the initial location; and

while traveling toward the initial location, via the processor, presenting an indicator that indicates a relative distance from at least one of the wireless communication devices.

2. The method of claim 1, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting a media access control (MAC) identifier for at least one of the communication devices.

3. The method of claim 1, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting an Internet protocol (IP) address for at least one of the communication devices.

4. The method of claim 1, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting at least one of the unique identifiers in accordance with a short range wireless communication protocol.

5. The method of claim 1, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting at least one of the unique identifiers from a wirelessly transmitted beacon.

6. The method of claim 1, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting at least one of the unique identifiers from a wireless communication device passed while traveling away from the initial location.

7. The method of claim 1, wherein presenting the indicator that indicates a relative distance from at least one of the wireless communication devices comprises presenting a plurality of the indicators, each of the indicators associated with a respective one of the wireless communication devices.

8. The method of claim 1, wherein presenting the indicator that indicates the relative distance comprises:

presenting the indicator in a first manner when the relative distance is decreasing; and

presenting the indicator in a second manner when the relative distance is increasing.

9. A method of identifying a route traveled, comprising:

while traveling away from an initial location, via a processor, detecting a unique identifier for each of a plurality of wireless communication devices along the route; and

while traveling toward the initial location, via the processor, presenting an indicator that indicates a relative distance from at least one of the wireless communication devices;

via the processor, associating each of the detected unique identifiers with a unique symbol; and

while traveling toward the initial location, via the processor, presenting a plurality of the unique symbols in an order that is reverse from the order in which the unique identifiers were detected;

wherein presenting the indicator that indicates the relative distance comprises presenting a plurality of such indicators and associating each of the presented indicators with a respective symbol.

10. A route identification device, comprising:

a receiver that, while traveling away from an initial location, detects a unique identifier for each of a plurality of wireless communication devices along the route, wherein the receiver detects the unique identifier from a wireless communication device within a parked vehicle passed while traveling away from the initial location; and

a user interface that, while traveling toward the initial location, presents an indicator that indicates a relative distance from at least one of the wireless communication devices.

11. The route identification device of claim 10, wherein the unique identifier detected by the receiver comprises a media access control (MAC) identifier for at least one of the communication devices.

12. The route identification device of claim 10, wherein the unique identifier detected by the receiver comprises an Internet protocol (IP) address for at least one of the communication devices.

13. The route identification device of claim 10, wherein the receiver detects the unique identifier in accordance with a short range wireless communication protocol.

14. The route identification device of claim 10, wherein the receiver detects the unique identifier from a wirelessly transmitted beacon.

15. The route identification device of claim 10, wherein the user interface presents a plurality of the indicators, each of the indicators associated with a respective one of the wireless communication devices.

16. The route identification device of claim 10, wherein the user interface presents the indicator in a first manner when the relative distance is decreasing, and presents the indicator in a second manner when the relative distance is increasing.

17. A route identification device, comprising:

a receiver that, while traveling away from an initial location, detects a unique identifier for each of a plurality of wireless communication devices along the route; and

a user interface that, while traveling toward the initial location, presents an indicator that indicates a relative distance from at least one of the wireless communication devices;

wherein;

the user interface associates each of the detected unique identifiers with a unique symbol;

while traveling toward the initial location, the user interface presents a plurality of the unique symbols in an order that is reverse from the order in which the unique identifiers were detected; and

the user interface presents a plurality of indicators that indicate relative distances from respective ones of the wireless communication devices, and associates each of the presented indicators with a respective symbol.

18. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for identifying a route traveled, said method steps comprising:

while traveling away from an initial location, detecting a unique identifier for each of a plurality of wireless communication devices along the route, wherein detecting the unique identifier for each of the plurality of wireless communication devices comprises detecting at least one of the unique identifiers from a wireless communication device within a parked vehicle passed while traveling away from the initial location; and

while traveling toward the initial location, presenting an indicator that indicates a relative distance from at least one of the wireless communication devices.
