Abstract

Methods, systems, and computer program products are disclosed for indicating a return route in a mobile device. A location identifier representing an intermediate point along a route is received and is independent of global positioning system information. A direction of travel is associated with the location identifier. Directional instructions indicating a return route passing through the intermediate point are determined. The directional instructions are determined based on the location identifier and the associated direction of travel without reference to a mapping database and independent of global positioning system information. The directional instructions are then presented.

Claims

1. A method for indicating a return route in a mobile device, the method comprising:

at a mobile device;

receiving a location identifier representing an intermediate point along a route, wherein the location identifier is independent of global positioning system information;

associating a direction of travel with the location identifier;

determining directional instructions indicating a return route passing through the intermediate point, the directional instructions being determined based on the location identifier and the associated direction of travel without reference to a mapping database and independent of global positioning system information; and

presenting the directional instructions.

2. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes reading a radio frequency identification tag.

3. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes:

receiving at least one short-range radio frequency signal; and

associating the at least one short-range radio frequency signal with the intermediate point.

4. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes reading a bar code.

receiving a digital image from a camera; and

associating the digital image with the intermediate point.

6. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes:

receiving an audio signal from an audio input; and

associating the audio signal with the intermediate point.

7. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes:

receiving text input via a user interface; and

associating the text input with the intermediate point.

8. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes:

receiving distance traveled information from a pedometer device; and

associating the distance traveled information with the intermediate point.

9. The method of claim 1 wherein receiving a location identifier representing an intermediate point along a route includes information from at least one of an anemometer, a clinometer, a barometer, and a clock.

10. The method of claim 1 wherein associating a direction of travel with the location identifier includes receiving text input via a user interface of the mobile device.

11. The method of claim 1 wherein associating a direction of travel with the location identifier includes receiving an audio signal from an audio input.

12. The method of claim 1 wherein associating a direction of travel with the location identifier includes receiving a compass signal indicating a direction of travel.

13. The method of claim 1 wherein determining directional instructions indicating a return route passing through the intermediate point includes generating a text string that includes directional instructions for reversing the direction of travel at the intermediate point.

14. The method of claim 1 wherein determining directional instructions indicating a return route passing through the intermediate point includes generating an audio file that includes directional instructions for reversing the direction of travel at the intermediate point.

15. The method of claim 1 wherein determining directional instructions indicating a return route passing through the intermediate point includes associating a digital image representing the intermediate point with directional instructions for reversing the direction of travel at the intermediate point.

16. The method of claim 1 wherein presenting the directional instructions comprises:

receiving a request to present directional instructions from a user via a user interface of the mobile device; and

presenting the directional instructions via the user interface.

17. The method of claim 1 wherein presenting the directional instructions includes displaying the directional instructions on a display of the mobile device.

18. The method of claim 1 wherein presenting the directional instructions includes playing an audio file representing the directional instructions on a speaker of the mobile device.

19. A computer program product comprising computer executable instructions embodied in a computer-readable medium for performing steps comprising:

receiving a location identifier representing an intermediate point along a route, wherein the location identifier is independent of global positioning system information;

associating a direction of travel with the location identifier;

determining directional instructions indicating a return route passing through the intermediate point, the directional instructions being based on the location identifier and the associated direction of travel without reference to a mapping database and independent of global positioning system information; and

presenting the directional instructions.

20. A system for indicating a return route in a mobile device, the system comprising:

means for receiving a location identifier representing an intermediate point along a route, wherein the location identifier is independent of global positioning system information;

means for associating a direction of travel with the location identifier;

means for determining directional instructions indicating a return route passing through the intermediate point, the directional instructions being based on the location identifier and the associated direction of travel without reference to a mapping database and independent of global positioning system information; and

means for presenting the directional instructions.

21. A system for indicating a return route in a mobile device, the system comprising:
