Subject matter disclosed herein relates to an apparatus, device, or method for detecting aim or pointing direction of a firearm, the method comprising detecting a sound signature of a gunshot from the firearm; sensing an aim direction of the firearm substantially at the time of detecting the sound signature of the gunshot; setting a reference direction based, at least in part, on the aim direction; sensing a current aim direction of the firearm; comparing the current aim direction to the reference direction; and initiating an alarm if the current aim direction is beyond a threshold angle of displacement from the reference direction.

1. A method for detecting a shooter's aim or pointing direction of a firearm, the method comprising: using a sound detector to detect a sound signature of a gunshot from said firearm;using a 3D sensor to sense an aim direction of said firearm substantially at the time of detecting said sound signature of said gunshot;using electronics or a processor to set a reference direction based, at least in part, on said aim direction;sense a current aim direction of said firearm;compare said current aim direction to said reference direction; andinitiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction. 2. The method of claim 1, wherein an intensity of said alarm is based, at least in part, on an angle of displacement from said reference direction. 3. The method of claim 1, further comprising detecting a sound signature of a round being loaded into a chamber of said firearm. 4. The method of claim 3, wherein an intensity of said alarm is based, at least in part, on said detecting said sound signature of said round being loaded into said chamber of said firearm. 5. The method of claim 1, further comprising using a finger placement detector to detect if a finger of a user is on or near a trigger of said firearm. 6. The method of claim 5, wherein an intensity of said alarm is based, at least in part, on said detecting if said finger is on or near said trigger of said firearm. 7. The method of claim 1, further comprising receiving instructions from a user to set or reset said threshold angle of displacement. 8. The method of claim 1, further comprising recording history of aim violations. 9. The method of claim 1, further comprising updating said reference direction based, at least in part, on a subsequent gunshot. 10. The method of claim 1, further comprising defeating shooting capability of said firearm based, at least in part, on said angle of displacement from said reference direction. 11. A device for detecting a shooter's aim or pointing direction of a firearm, the device comprising: a sound detector to detect a sound of a gunshot from said firearm;a 3D sensor to sense an aim direction of said firearm; anda processor or electronics to: set a reference direction based, at least in part, said aim direction at a time when said sound of said gunshot is detected;compare a current aim direction to said reference direction; andinitiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction. 12. The device of claim 11, wherein said processor or electronics changes an intensity of said alarm based, at least in part, on an angle of displacement from said reference direction. 13. The device of claim 11, wherein said sound detector is further configured to detect a sound signature of a round being loaded into a chamber of said firearm. 14. The device of claim 13, wherein said processor or electronics are capable of learning said sound signature of said round being loaded into said chamber of said firearm. 15. The device of claim 11, further comprising a finger placement detector to detect if a finger of a user is on or near a trigger of said firearm. 16. The device of claim 11, further comprising a rest pad for a finger of a user, wherein said processor or electronics is configured to detect if said finger is contacting a rest pad. 17. The device of claim 11, wherein said processor or electronics are capable of updating said reference direction based, at least in part, on a subsequent gunshot. 18. The device of claim 11, wherein said processor or electronics are capable of uploading histories stored in a memory to an electronic device, wherein said histories comprise a history of gunshots and/or a history of aim violations. 19. The device of claim 11, wherein said processor or electronics are capable of defeating shooting capability of said firearm based, at least in part, on said angle of displacement from said reference direction. 20. A non-transitory storage medium comprising machine-readable instructions stored thereon that are executable by a special purpose computing device to: identify a sound signature of a gunshot from said firearm;determine an aim direction of said firearm substantially at the time of identifying said sound signature of said gunshot;set a reference direction based, at least in part, on said aim direction;determine a current aim direction of said firearm;compare said current aim direction to said reference direction; andinitiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction.
