Abstract

Aspects of the present disclosure relate to visual presentation techniques for micro-Doppler signatures. A method may include receiving a micro Doppler signature indicative of a projectile flight path, identifying a beginning trace marker and a termination trace marker, and presenting in a head-worn computing system field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn computing system such that the digital content appears to remain referenced to the environment independent of a position of the head-worn computing system.

Claims

1. A method, comprising:

receiving data indicative of a projectile flight path;

identifying a beginning trace marker and a termination trace marker;

presenting in a head-worn computing system field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn computing system such that the digital content appears to remain referenced to the environment independent of a position of the head-worn computing system; and

identifying a source of the projectile flight path as either friendly fire or enemy fire.

2. The method of claim 1, wherein the digital content has a color based on the source of the projectile flight path.

3. The method of claim 1, wherein the source is identified at least in part based on the location of the beginning trace marker.

4. The method of claim 2, wherein an aspect of the color changes as a velocity of the projectile changes.

5. A method, comprising:

receiving data indicative of a projectile flight path;

identifying a beginning trace marker and a termination trace marker; and

presenting in a head-worn computing system field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn computing system such that the digital content appears to remain referenced to the environment independent of a position of the head-worn computing system;

wherein the step of presenting the digital content representative of the projectile flight path further comprises presenting digital content indicative of a location of a non-enemy combatant.

6. A head-worn apparatus, comprising:

a communication system adapted to receive a micro Doppler signature indicative of a projectile flight path; and

a processor adapted to identify a beginning trace marker and a termination trace marker, the processor further adapted to present in the head-worn apparatus field of view digital content representative of the projectile flight path, wherein the beginning trace marker and termination trace marker provide a world-lock perspective for a wearer of the head-worn apparatus such that the digital content appears to remain referenced to an environment independent of a position of the head-worn apparatus.

7. The head-worn apparatus of claim 6, wherein the processor is further adapted to identify a source of the projectile flight path as either friendly fire or enemy fire.

8. The head-worn apparatus of claim 7, wherein the digital content has a color based on the source of the projectile flight path.

9. The head-worn apparatus of claim 7, wherein the source is identified at least in part based on the location of the beginning trace marker.

10. The head-worn apparatus of claim 8, wherein an aspect of the color changes as a velocity of the projectile changes.

11. The head-worn apparatus of claim 6, wherein the digital content representative of the projectile flight path further comprises digital content indicative of a location of a non-enemy combatant.
