Methods and Systems for Determining Recoil Dynamics and Firearm Motion During Gunshot Event

Abstract

An apparatus, device, or method may be used for, among other things, shooting performance training. An apparatus or device performing the method may receive from a motion sensor electronic signals representative of motion of a firearm; detect a shot of the firearm; track, based at least in part on the electronic signals, the motion of the firearm before and/or after detecting the shot to generate tracking data; retrieve, from an electronic memory, a reference target direction that is based at least in part on a voice command; and based at least in part on the tracking data and the reference target direction, generate data, regarding the motion of the firearm, for a display of a user interface. The voice command indicates the reference target direction, which is the orientation of the firearm when the voice command is received.

What is claimed is: 
     
         1 . A method for shooting performance training, the method comprising:
 receiving from a motion sensor electronic signals representative of motion of a firearm;   detecting a shot of the firearm;   tracking, based at least in part on the electronic signals, the motion of the firearm before detecting the shot to generate tracking data;   retrieving, from an electronic memory, a reference target direction that is based at least in part on a voice command; and   based at least in part on the tracking data and the reference target direction, generating data, regarding the motion of the firearm, for a display of a user interface.   
     
     
         2 . The method of  claim 1 , further comprising, before detecting the shot:
 receiving from the motion sensor electronic signals representative of orientation of the firearm; and   receiving the voice command, which indicates the reference target direction, wherein the reference target direction is the orientation of the firearm when the voice command is received.   
     
     
         3 . The method of  claim 1 , further comprising tracking, based at least in part on the electronic signals, the motion of the firearm after detecting the shot to generate the tracking data. 
     
     
         4 . The method of  claim 1 , further comprising tracking, based at least in part on the electronic signals, the motion of the firearm during a trigger pull that results in the shot. 
     
     
         5 . The method of  claim 1 , further comprising wirelessly transmitting the data to a user interface, wherein the user interface is on a smartphone or other wireless device. 
     
     
         6 . The method of  claim 1 , wherein generating the data for the display of the user interface comprises: generating data for displaying a plot in the display, wherein the plot represents the tracked motion of the firearm before, substantially during, or after the shot. 
     
     
         7 . The method of  claim 6 , wherein the plot further represents the tracked motion of the firearm with respect to the reference target direction. 
     
     
         8 . The method of  claim 1 , further comprising providing to a user real-time audio or visual feedback that indicates deviation of an aim direction of the firearm from the reference target direction. 
     
     
         9 . A device comprising:
 electronic memory;   one or more motion sensors; and   a processor or electronics configured to: 
 receive, from the one or more motion sensors, electronic signals representative of motion of a firearm; 
 detect a shot of the firearm; 
 track, based at least in part on the electronic signals, the motion of the firearm before detecting the shot to generate tracking data; 
 retrieve, from the electronic memory, a reference target direction based at least in part on a voice command; and 
 based at least in part on the tracking data and the reference target direction, generating data, regarding the motion of the firearm, for a display of a user interface. 
   
     
     
         10 . The device of  claim 9 , wherein the processor or electronics are further configured to, before detecting the shot:
 receive from the one or more motion sensors electronic signals representative of orientation of the firearm; and   receive the voice command, which indicates the reference target direction, wherein the reference target direction is the orientation of the firearm when the voice command is received.   
     
     
         11 . The device of  claim 9 , wherein the processor or electronics are further configured to track, based at least in part on the electronic signals, the motion of the firearm after detecting the shot to generate the tracking data. 
     
     
         12 . The device of  claim 9 , wherein the processor or electronics are further configured to track, based at least in part on the electronic signals, the motion of the firearm during a trigger pull that results in the shot. 
     
     
         13 . The device of  claim 9 , wherein generating the data for the display of the user interface comprises: generating data for displaying a plot in the display, wherein the plot represents the tracked motion of the firearm. 
     
     
         14 . The device of  claim 13 , wherein the plot further represents the tracked motion of the firearm with respect to the reference target direction. 
     
     
         15 . The device of  claim 9 , further comprising a trigger sensor configured to measure rate of trigger pull, wherein the processor or electronics are further configured to:
 generate a history of rates of trigger pull; and   determine trigger pull consistencies and/or irregularities of a shooter based on the history.   
     
     
         16 . The device of  claim 9 , further comprising a trigger sensor configured to indicate whether a user’s finger is touching a trigger of the firearm. 
     
     
         17 . A method for measuring motion of a firearm, the method comprising:
 receiving from a motion sensor electronic signals representative of the motion of the firearm and the orientation of the firearm;   receiving a voice command to indicate a reference target direction, wherein the reference target direction is the orientation of the firearm when the voice command is received;   detecting a shot of the firearm;   tracking, based at least in part on the electronic signals, the motion of the firearm before detecting the shot to generate tracking data; and   based at least in part on the tracking data and the reference target direction, generating data, regarding the motion of the firearm, for a display of a user interface.   
     
     
         18 . The method of  claim 17 , further comprising tracking, based at least in part on the electronic signals, the motion of the firearm after detecting the shot to generate the tracking data.
