Recording Data during Firearm Operation
« on: October 18, 2018, 03:25:28 PM »
I have developed an Apple Watch app called WatchForce. I wanted to record the motion and forces an Apple Watch can detect via the accelerometer and gyroscopes.

I have used this app on thrill rides and roller coasters, AND I have used it while shooting pistols.

Here is the G-Forces recorded while shooting my CZ 85B.



Now I know that an Apple Watch and iPhone are not inexpensive, but hey, if you have them already you can use the app to discover some interesting information.

Here I select the data and I can see very precise values including their times.



Since this is done via the watch and not using sound, there is no interference from others at the range.

What other things might you want to measure?

Here I measure the recoil recovery time by selecting the point where the shot is clearly underway, the highest point, and the first point where the motion has settled down.



I find it interesting. Maybe if I could get a few hundred or even thousand data sets from users I could Machine Learn a very sophisticated shot analyzer. This is a starting place at least!

It was asked of me if the WatchForce can detect / record dry firing or drawing your handgun.


Let's start with dry firing.

I used my S&W 659, double action mode. All of my pistols are metal, hammer fired types.

Five dry fires



Using the filter slider I remove noise until it seems reasonable and then I tap to get some data.



I have no idea what might be recorded with a really smooth and soft trigger.

Now to the drawing of my handgun.

I was pleased to see the motion is easily recognized.



So, I select where I think the motion started and stopped and I get a time for the draw.



I did this several times and the motion pattern was very similar each time.

If you have an Apple Watch try it out. It is free for now.

I don?t have an Apple Watch but if I did then I would use this app for sure! Thanks for making it and sharing it!
