An apparatus, device, or method may detect aim or pointing direction of a firearm, and may display aim directions of the firearm for gunshots fired at a target. Sequence of bullet strikes by multiple gunshots may be determined. A method may comprise detecting gunshots of the firearm discharging live ammunition, measuring aim directions of the firearm substantially at times of detecting the gunshots, recording the times of the gunshots and/or sequence order of the gunshots, and generating output for displaying an image that includes bullet strike icons that represent bullet strikes on the target. Locations of the bullet strike icons in the image may be based, at least in part, on the measured aim directions of the gunshots.

1. A method comprising: using a detector or a sensor to detect a gunshot of a firearm;using a 3D sensor to sense an aim direction of the firearm substantially at the time of detecting the gunshot;using electronics or a processor to set a reference direction based, at least in part, on the aim direct
1. A method comprising: using a detector or a sensor to detect a gunshot of a firearm;using a 3D sensor to sense an aim direction of the firearm substantially at the time of detecting the gunshot;using electronics or a processor to set a reference direction based, at least in part, on the aim direction;using the 3D sensor to sense subsequent aim directions of the firearm after the time of detecting the gunshot; andusing the electronics or the processor to: compare any of the subsequent aim directions to the reference direction;measure recoil of the firearm, wherein the measuring is based, at least in part, on the comparing; anddisplay and/or record the measured recoil of the firearm. 2. The method of claim 1, wherein measuring recoil of the firearm generates one or more recoil measurements that include an angle of any of the subsequent aim directions with respect to the reference direction. 3. The method of claim 2, further comprising: using the electronics or the processor to decompose the angle into a first axis that is substantially parallel with the reference direction and a second axis that is perpendicular to the first axis. 4. The method of claim 1, wherein measuring recoil of the firearm generates one or more recoil measurements that include a maximum angle of the subsequent aim directions with respect to the reference direction. 5. The method of claim 1, further comprising: using the detector or the sensor to detect a second gunshot of the firearm;using the 3D sensor to sense a second aim direction of the firearm substantially at the time of detecting the second gunshot;using the 3D sensor to sense a second set of subsequent aim directions of the firearm after the time of detecting the second gunshot; andusing the electronics or the processor to: compare any of the second subsequent aim directions to the reference direction; andgenerate one or more recoil measurements based, at least in part, on the comparing. 6. The method of claim 1, wherein displaying and/or recording the measured recoil comprises producing an audible signal or alarm. 7. The method of claim 1, further comprising: using the electronics or the processor to record the measured recoil in a memory to record a history of recoil measurements. 8. The method of claim 1, further comprising: using the electronics or the processor to update the reference direction based, at least in part, on a subsequent gunshot. 9. The method of claim 1, wherein displaying and/or recording the measured recoil comprises displaying the measured recoil on a display that is remote from the firearm. 10. The method of claim 1, further comprising generating a plot of the measured recoil as a function of time and displaying the plot on a display. 11. The method of claim 1, further comprising: using the electronics or the processor to calculate respective speeds of translation and/or rotation based, at least in part, on the measured recoil. 12. A device comprising: one or more detectors to detect discharge of a firearm;a 3D sensor to sense (i) an aim direction of the firearm substantially at the time of detecting the discharge, and (ii) subsequent aim directions of the firearm after the time of detecting the discharge; anda processor or electronics to: set a reference direction based, at least in part, on the aim direction of the firearm substantially at the time of detecting the discharge;compare any of the subsequent aim directions to the reference direction;calculate recoil of the firearm based, at least in part, on the comparing; andtransmit the calculated recoil to at least one of a display, a memory, or a remote device. 13. The device of claim 12, wherein the calculated recoil of the firearm includes one or more recoil measurements that each include an angle of any of the subsequent aim directions with respect to the reference direction. 14. The device of claim 12, wherein the one or more detectors and the 3D sensor are located on at least a portion of the firearm and the processor or electronics are located remotely from the firearm and wherein the one or more detectors and the processor or electronics are enabled to wirelessly communicate with one another. 15. The device of claim 12, further comprising the display enabled to display a plot of recoil as a function of time. 16. The device of claim 12, wherein the processor or electronics are capable of updating the reference direction based, at least in part, on a subsequent discharge of the firearm.
