Abstract

Claims (34)

1. A system, comprising:

a head worn display configured to display symbology of an operating environment;

a tracking camera;

a tracking processing unit communicatively coupled to the tracking camera configured to:

determine a position and orientation of the head worn display; and

transmit a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value; and

the controller communicatively coupled to the head worn display and the tracking camera comprising:

one or more processors; and

a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to:

display the symbology on the head worn display;

determine a quality-of-service value based on at least the signal quality value; and

modify, graphically, at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if based on the quality-of-service value changing from a high-quality value to a low-quality value.

2. The system of claim 1 , wherein the instructions further cause the one or more processors to:

receive a sensor signal from one or more sensors; and

use the sensor signal to determine the quality-of-service value.

3. The system of claim 1 , wherein the quality-of-service value comprises an accuracy characteristic.

4. The system of claim 1 , wherein the quality-of-service value comprises a precision characteristic.

5. The system of claim 1 , wherein the quality-of-service value comprises a signal strength characteristic.

6. The system of claim 1 , wherein the degraded symbol is configured as a removed symbol.

7. The system of claim 1 , wherein the degraded symbol is configured with a different color than the default symbol.

8. The system of claim 1 , wherein the degraded symbol is configured with a different line width than the default symbol.

9. The system of claim 1 , wherein the degraded symbol is configured with a different line type than the default symbol.

10. The system of claim 1 , wherein the controller is communicatively coupled to a vision system.

11. The system of claim 1 , further comprising an inertial sensor communicatively coupled to at least one of the head worn display or the tracking processing unit.

12. The system of claim 1 , wherein the at least one symbol represents a confidence line of a path.

13. The system of claim 12 , wherein the path is configured as a runway.

14. A method for modifying symbology displayed on a head worn display (HWD) based on a quality-of-service value comprising:

determining a position and orientation of the HWD;

transmitting a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value;

determining a quality-of-service value based on at least the signal quality value; and

displaying symbology on the HWD, wherein at least one symbol of the symbology is graphically modified from a default form to a degraded form based on the quality-of-service value.

15. The method of claim 14 , further including:

receiving a sensor signal from one or more sensors; and

using the sensor signal to determine the quality-of-service value.
