Shooter Aim Detection and Warning System
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:
detecting a sound signature of a gunshot from said firearm;
sensing said shooter's aim direction of said firearm substantially at the time of detecting said sound signature of said gunshot;
setting a reference direction based, at least in part, on said aim direction;
sensing said shooter's current aim direction of said firearm;
comparing said current aim direction to said reference direction; and
initiating 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 detecting 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 said shooter's aim direction of said firearm; and
a processor or electronics to:
set a reference direction based, at least in part, on aim direction at a time when said sound of said gunshot is detected;
compare said shooter's current aim direction to said reference direction; and
initiate an alarm if 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 a shooter's 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 said shooter's current aim direction of said firearm;
compare said current aim direction to said reference direction; and
initiate an alarm if said current aim direction is beyond a threshold angle of displacement from said reference direction.
