Abstract

A point of aim shows where a weapon is aimed on a target. An electronic device determines an impact location on the target of a projectile fired from the weapon, determines a distance from the point of aim to the impact location, and moves the point of aim in order to sight the weapon to the target.

First claim

What is claimed is:

1. A method comprising:
displaying, on a display of a wearable electronic device (WED) worn on a head of a user with a rifle, a point of aim (POA) of the rifle that is sighted for targets at a first distance;
receiving, at the WED worn on the head of the user and from an electronic scope mounted to the rifle, a second distance from the rifle to a target;
automatically moving, by the WED and in response to a difference between the first distance and the second distance, a location where the POA is displayed on the display of the WED to sight the rifle to the second distance; and
moving where the POA is displayed on the display of the WED in real-time with movements of the rifle so the POA displayed on the WED shows a point of impact (POI) of a bullet fired from the rifle.

2. The method of claim 1 , wherein the POA moves on the display of the WED to compensate for bullet drop due to the difference between the first distance and the second distance.

3. The method of claim 1 further comprising:
receiving, from a camera mounted to the rifle, an image or a video of an impact location that shows where the bullet fired from the rifle impacted the target;
analyzing, by the WED, the image or the video to determine a difference between the impact location and the POA when the bullet was fired; and
automatically moving, by the WED, where the POA is displayed on the display of the WED to compensate for the difference between the impact location and the POA when the bullet was fired.

4. The method of claim 1 further comprising:
obtaining, by the WED, a wind speed and a wind direction at a location of the WED; and
automatically moving, by the WED, where the POA is displayed on the display of the WED to compensate for the wind speed and the wind direction at the location of the WED.

5. The method of claim 1 further comprising:
determining, by the WED and from information captured with the electronic scope, a speed of the target; and
automatically moving, by the WED, where the POA is displayed on the display of the WED to compensate for the speed of the target.

6. The method of claim 1 further comprising:
determining, by the WED and from one or more images or video captured with the electronic scope, a pattern of multiple impact locations of bullets that struck the target; and
improving sighting of the rifle by automatically moving, by the WED, where the POA is displayed on the display of the WED to compensate for the pattern of the multiple impact locations of the bullets that struck the target.

7. The method of claim 1 further comprising:
receiving, by the WED and from the electronic scope, a compass direction that the rifle is pointed; and
automatically moving, by the WED, where the POA is displayed on the display of the WED to compensate for wind speed and wind direction with respect to the compass direction.

8. The method of claim 1 further comprising:
tracking, with the WED, an orientation of the rifle; and
deactivating a weapon targeting system (WTS) that the WED executes when the orientation of the rifle points to ground.

9. A non-transitory computer readable storage medium storing instructions that cause one or more processors to execute a method, comprising:
displaying, on a display of a wearable electronic device (WED) worn on a head of a user with a rifle, a point of aim (POA) of the rifle;
receiving, at the WED worn on the head of the user and from an electronic device mounted to the rifle, a distance from the rifle to a target;
moving, by the WED, a location where the POA is displayed on the display of the WED so the rifle is sighted to the distance; and
moving where the POA is displayed on the display of the WED in real-time with movements of the rifle so the POA displayed on the WED shows a point of impact (POI) of a bullet fired from the rifle.

10. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
tracking, with the WED, an orientation of the rifle; and
activating a weapon targeting system (WTS) that the WED executes when the orientation of the rifle points to the target.

11. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
determining, from one or more images of the target captured with the electronic device mounted to the rifle, a difference between the POA when the bullet was fired from the rifle and an impact location where the bullet struck the target; and
moving, based on the difference, where the POA is displayed on the display of the WED to improve sighting of the rifle.

12. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
determining, from video captured with the electronic device mounted to the rifle, where bullets fired from the rifle impact the target or miss the target; and
moving, based on where the bullets fired from the rifle impact the target or miss the target, where the POA is displayed on the display of the WED to improve sighting of the rifle.

13. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
calculating a speed of the target moving; and
adjusting where the POA is displayed on the display of the WED so the user does not have to lead the target that is moving but instead places the POA on the target to hit the target with the bullet fired from the rifle.

14. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
retrieving, over a wireless network and by the WED, shooting conditions that include a wind speed and a wind direction; and
moving, by the WED, where the POA is displayed on the display of the WED the POA to compensate for the shooting conditions.

15. The non-transitory computer readable storage medium storing instructions of claim 9 in which the method further comprises:
moving, by the WED, where the POA is displayed on the display of the WED the POA to compensate for bore temperature of the rifle.

16. Wearable electronic glasses (WEG) worn on a head of a user with a rifle, the WEG comprising:
a wireless receiver that receives, from an electronic scope mounted to the rifle, a distance to a target at which the rifle is aimed;
a display that displays a point of aim (POA) of the rifle and that moves the POA in real-time with movements of the rifle; and
a processor that executes code to sight the rifle to the target by moving, based on the distance to the target, a location where the POA is displayed on the display and to move where the POA is displayed on the display of the WEG in real-time with movements of the rifle so the POA displayed on the WEG shows a point of impact (POI) of a bullet fired from the rifle.

17. The WEG of claim 16 further comprising:
one or more sensors that sense an orientation of the rifle, wherein the processor executes the code to activate and to deactivate a weapon targeting system (WTS) based on the orientation of the rifle.

18. The WEG of claim 16 , wherein the processor executes the code to move the location where the POA is displayed on the display based on a bore temperature of the rifle.

19. The WEG of claim 16 , wherein the processor executes the code to move the location where the POA is displayed on the display to compensate for bullet drop when the distance to the target changes.
