psmove rotational and positional data to opentrack (its working)

[VerdeMsk]

Hi all. Registered just to share a script if somebody will be searching for a similar thing.
I was trying to make headtracking with a psmove controller.
Of course there are some apps which seems to be working in that way, but they are limited to positional data via light bulb and ps eye camera. And I needed rotational data.
Also Freepie has feature to convert data to freetrack, but for some reason not all apps I've seen reads it (driver4vr for example). Also it's hard to tune for a newbies and has no filters, etc.
So I was searching for a way to send it to opentrack instead.
First I asked chatgpt to write me a script, but it was only half working (still it's awesome - it helped me to understand code a little bit).
Then I've found a post on that forum by Me4huk who posted a script for trackir, I edited it a little bit, tested with opentrack's UDP over network and voila - it's working.
I don't have a ps eye camera, so psmove sends only rotational data, but looks like positional data will also work.
In opentrack it's possible to use fusion input, so it's available to mix it with aruco, neuralnet and other sources.
In order to use it you will need psmove service(or psmoveserviceEX) and psmovefreepiebridge running.
In opentrack choose UDP over network input (or fusion with same setting).
If some axis doesn't work upon starting push recenter button.

I hope it helps somebody

You're able to use a script that Me4huk posted on a forum for the TrackIR device, and then modified it to work with the PS Move controller and OpenTrack. This allowed you to send the PS Move's rotational data to OpenTrack via UDP over network input, and then use OpenTrack's fusion input feature to combine it with other sources such as ArUco or neural net data.
