Abstract

Aspects of the present invention relate to visual presentation techniques for mD signatures.

Claims

1. A method, comprising:

a. receiving a micro Doppler signature indicative of a projectile flight path;

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

c. 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.

2. The method of claim 1, further comprising:

a. confirming a distance from the head-worn computing system to a point in the environment associated with the beginning trace marker, wherein the confirmation is used to confirm the head-worn computing system is positioning the beginning trace marker with a correct environmental position.

3. The method of claim 1, wherein a micro Doppler system that produces the micro Doppler signature is located proximate the head-worn computing system.

4. The method of claim 1, wherein a micro Doppler system that produces the micro Doppler signature is located remotely from the head-worn computing system.

5. The method of claim 1, wherein the beginning trace marker represents a position of a known person.

6. The method of claim 5, wherein the known person is a friendly combatant.

7. The method of claim 5, wherein the known person is an unfriendly combatant.

8. The method of claim 1, wherein the beginning trace marker represents a position of an unknown person.

9. The method of claim 1, wherein the digital content representative of the projectile flight path is color-coded.

10. The method of claim 9, wherein the color-coding illustrates a type of combatant identified proximate the beginning trace marker.

11. The method of claim 9, wherein the color-coding illustrates a decreasing speed of a projectile.

12. The method of claim 1, wherein the digital content representative of the projectile flight path represents both a type of combatant and a speed of a projectile.
