Abstract

An article is worn by a user. A plurality of indicating devices are coupled to the article. A processing unit is communicatively coupled to the plurality of indicating devices. The processing unit selectively actuates at least one indicating device of the plurality of indicating devices based on positional data.

Claims

1. A method for indicating a direction, said method comprising:

coupling a plurality of indicating devices to a user device, the user device configured to be worn by a user;

coupling a processor to the plurality of indicating devices;

configuring the processor to;

determine orientation data regarding an orientation of the user device;

transmit a signal including the orientation data to a control system that is remote from the user, the signal having a pre-defined signal signature configured for comparison to criteria stored in the control system, and the control system configured for identifying the user device as one or both of an active target and an active tracking device based on the pre-defined signal signature;

receive positional data from the control system if the user device is identified as the active tracking device, the positional data associated with a target location; and

selectively actuate at least one indicating device of the plurality of indicating devices based on the positional data, wherein the plurality of indicating devices are configured to provide non-visual feedback to the user when actuated.

2. A method in accordance with claim 1, further comprising configuring the processor to selectively actuate the at least one indicating device based on the remote control system identifying the user device as the active tracking device using at least the orientation data.

3. A method in accordance with claim 1, further comprising configuring the processor to actuate the at least one indicating device in a pattern to indicate an uncertainty of the target location.

4. A method in accordance with claim 3, further comprising configuring the processor to actuate the at least one indicating device to indicate uncertainty in three-dimensional space.

5. A method in accordance with claim 1, further comprising configuring the processor to selectively actuate the at least one indicating device more frequently as the at least one indicating device is moved closer to the target location.

6. A method in accordance with claim 1, further comprising configuring the processor to selectively actuate the at least one indicating device based on the user device orientation data.

7. A method in accordance with claim 1, further comprising configuring the processor to generate at least one of a tactile signal and an auditory signal using at least one of the plurality of indicating devices.

8. A method in accordance with claim 1, further comprising configuring the processor to selectively actuate the at least one indicating device in a predetermined pattern indicative of a line of bearing towards the target location.

9. The method in accordance with claim 1, wherein configuring the processor further comprises configuring the processor to transmit the signal to the control system configured to identify the user device based at least partially on the condition of the user device, the condition including an active state, a sleep state, a target state, a tracking device state, a standard state, or an emergency state.

10. A system for indicating direction, said system comprising:

a user device configured to be worn by a user;

a plurality of indicating devices coupled to said user device; and

a processor communicatively coupled to said plurality of indicating devices, wherein said processor is programmed to;

determine orientation data regarding an orientation of the user device;

transmit a signal including the orientation data to a control system that is remote from the user, the signal having a pre-defined signal signature configured for comparison to criteria stored in the control system, and the control system configured for identifying the user device as one or both of an active target and an active tracking device based on the pre-defined signal signature;

receive positional data from the control system if the user device is identified as the active tracking device, the positional data associated with a target location; and

selectively actuate at least one indicating device of said plurality of indicating devices based on the positional data, wherein the plurality of indicating devices are configured to provide non-visual feedback to the user when actuated.

11. A system in accordance with claim 10, wherein said processor is further programmed to selectively actuate the at least one indicating device based on the remote control system identifying said user device as an active tracking device using at least the orientation data.

12. A system in accordance with claim 10, wherein said processor is further programmed to selectively actuate the at least one indicating device by selectively actuating in a pattern to indicate an uncertainty of the target location.

13. A system in accordance with claim 12, wherein said processor is further programmed to selectively actuate in a pattern to indicate an uncertainty of a target location by actuating said at least one indicating device to indicate uncertainty in three-dimensional space.

14. A system in accordance with claim 10, wherein said processor is further programmed to selectively actuate the at least one indicating device by actuating more frequently as said at least one indicating device is moved closer to the target location.

15. A system in accordance with claim 10, wherein said processor is further programmed to selectively actuate the at least one indicating device based on the user device orientation data.

16. A system in accordance with claim 10, wherein said processor is further programmed to generate at least one of a tactile signal and an auditory signal using at least one of said plurality of indicating devices.

17. A system in accordance with claim 10, wherein said processor is further programmed to selectively actuate the at least one indicating device in a predetermined pattern indicative of a line of bearing towards the target location.

18. A system in accordance with claim 10 further comprising the control system configured to receive the signal from the processor.
