Android>FreeTrack/TrackIR>Elite Dangerous

[TheRealBix]

Hi everyone !

I'm trying to set up my Nexus 5 as a head track device.

I used to launch facetracknoir with the faceapi but the response is really low and it doesn't work in the dark. Anyway, it was working with both freetrack and trackIR protocols.

Now, I want to check if the sensors are ready for this kind of things so i've installed Wireless IMU and FreePIE IMU on the Nexus, and picked up here and there some parts of scripts :

As Wireless IMU doesn't seem to send readable data by FreePIE, I use FreePIE IMU.

Here both scripts for freetrack and trackir protocols.

Code: Select all

def update():
    global yaw
    yaw = android[0].yaw
    global pitch
    pitch = -android[0].roll
    global roll
    roll = android[0].pitch

if starting:
    centerYaw = 0
    centerPitch = 0
    centerRoll = 0
   
    yaw = 0
    pitch = 0
    roll = 0
    android[0].update += update

freeTrack.yaw  = yaw - centerYaw
freeTrack.pitch = pitch - centerPitch
freeTrack.roll = roll - centerRoll

if keyboard.getKeyDown(Key.LeftControl) and keyboard.getPressed(Key.C):
    centerYaw = yaw
    centerPitch = pitch
    centerRoll = roll
    
diagnostics.watch(freeTrack.yaw)
diagnostics.watch(freeTrack.pitch)
diagnostics.watch(freeTrack.roll)

Code: Select all

def update():
  global yaw
  yaw = filters.deadband(math.degrees(filters.continuousRotation(android[0].googleYaw)), deadband)
  global pitch
  pitch = filters.deadband(math.degrees(-android[0].googlePitch), deadband)
  global roll
  roll = filters.deadband(math.degrees(-android[0].googleRoll), deadband)

if starting:
  deadband = 0.01
  centerYaw = 0
  centerPitch = 0
  centerRoll = 0

  yaw = 0
  pitch = 0
  roll = 0
  android[0].update += update

trackIR.yaw = yaw - centerYaw
trackIR.pitch = pitch - centerPitch
trackIR.roll = roll - centerRoll

if keyboard.getKeyDown(Key.LeftControl) and keyboard.getPressed(Key.C):
  centerYaw = yaw
  centerPitch = pitch
  centerRoll = roll
  
diagnostics.watch(trackIR.yaw)
diagnostics.watch(trackIR.pitch)
diagnostics.watch(trackIR.roll)

Both options work, Freepie can read values.
The problem is that Elite doesn't recognize any of those..

May I have to use opentrack/facetracknoir in an "android>Freepie>opentrack>Elite" thing ?

Thanks for your future answers

It works with the real Freetrack but not with FreePIE?

[TheRealBix]

I confirm, it works with FTnoIR + faceAPI + Freetrack protocol + Freetrack interface.

edit : I've just checked the freetrack path in the registry and it's good, ProgramFiles/Freepie..

[CyberVillain]

Ok, we use the old Freetrack interface directly, we even use their dll
Can you try just the Freetrack interface and play the demo in the Freetrack client, does that work too?

[TheRealBix]

Sorry for the late answer (holidays )

So, no, it doesn't work.
In fact because of you i've searched if it was a known thing, but only with the original freetrack soft, and actually it is.

I don't really know why, but it works. Maybe it's related to the csv available here, I think you'll understand the weird thing better than me..

And thanks for your time

[TheRealBix]

Here is my final script if someone wanna take a look :

Code: Select all

def update():
    global yaw
    yaw = filters.deadband(filters.simple(filters.continuousRotation(android[0].googleYaw), smooth), dead)
    global pitch
    pitch = filters.deadband(filters.simple(android[0].googlePitch, smooth), dead)
    global roll
    roll = filters.deadband(filters.simple(android[0].googleRoll, smooth), dead)

if starting:
    dead = 0			#Defaut = 0   : Censé diminuer le drift. Ne semble pas marcher pas chez moi, je laisse donc à zéro.
    smooth = 0.9 		#Defaut = 0.9 : Permet de lisser les mouvements de tête. Ajuster de 0 à 1 selon la sensibilité de votre estomac.
    centerYaw = 0
    centerPitch = 0
    centerRoll = 0

    yaw = 0
    pitch = 0
    roll = 0
    android[0].update += update

#Là dessous, c'est les données balancées au jeu avec pour chaque axe une petite équation représentant une courbe. Ajustez les selon votre convenance, celles-ci me paraissent assez bonnes.
#Attention aux torticolis !
freeTrack.yaw  = -1.5*(yaw - centerYaw) - 10*(yaw - centerYaw)**3
freeTrack.pitch = 2*(pitch - centerPitch) + 5*(pitch - centerPitch)**3
freeTrack.roll = -1.3*(roll - centerRoll) - 2*(pitch - centerRoll)**3


#Ici, vous pouvez modifier le raccourci pour l'ajustement du zéro. Home par défaut.
if keyboard.getPressed(Key.Home):
    centerYaw = yaw
    centerPitch = pitch
    centerRoll = roll


#Décommentez les lignes suivantes pour voir les données transmises par le smartphone et par FreePIE au jeu.

#diagnostics.watch(android[0].googleYaw)
#diagnostics.watch(android[0].googlePitch)
#diagnostics.watch(android[0].googleRoll)

#diagnostics.watch(freeTrack.yaw)
#diagnostics.watch(freeTrack.pitch)
#diagnostics.watch(freeTrack.roll)

Nice that you got it to work, what was wrong?

edit: Both Freetrack and Android uses absolute cordinate systems so I see no point in doing filters.continuousRotation or deadband

[TheRealBix]

It seems that Elite need to detect the tracker software before collecting track data. So I had to launch Opentrack or FTnoIR in order to "lock" the game then run the FreePie script. It's weird, but it works. Maybe future updates will correct this. (This is the only game I have to do this)

The deadband filter actually doesn't do anything on me. That's why I've disabled it (tests.. )

On the other side, the continuousrotation is required. Without it, the value jumps to negative and "teleport" the vision to the opposite. Maybe I did something wrong but that's what happen to me
When I turn my head, once -pi is reached, it jumps to +pi (which correspond to 20 degrees to the left for me)

[CyberVillain]

But running FreePIE should do the same? Hmm, there is one thing we do not do however, we do not have a fake freetrack.exe that runs, maybe they check for that.. Dumb check if you ask me

[TheRealBix]

No, it doesn't work with a freetrack.exe, at least I don't see it in the task manager.
In the interface settings of those softwares it seems that a NPClient.dll is required and used, maybe it's related ?

[CyberVillain]

NPClient.dll is for TrackIR, has nothing todo with Freetrack

Hi. i tryed also this. but...

diagnostics.watch(android[0].googleYaw)
diagnostics.watch(android[0].googlePitch)
diagnostics.watch(android[0].googleRoll)

Give nothing out!

only this works then setting the android app to raw data:

diagnostics.watch(android[0].yaw)
diagnostics.watch(android[0].pitch)
diagnostics.watch(android[0].roll)

any problems then using raw data?

Numbers of ra data counting up and deasnt stand still.... :/

[CyberVillain]

Have you ticked the Orientation checkbox on the Android app?
If you tick Debug do you see values?

[wax7]

Not Moving Handy.

Looks like the phone does not support orientation, that is a bit strange

[wax7]

The Phone is the Brand new "OnePlus One"

[wax7]

mmmh. no Orientation Sensors....

[CyberVillain]

Very strange, maybe call the support?

[wax7]

Tryed now my old Milestone Handy. But its like i have an Earthquake.... not usefull. need more Cell Phones for TEsting

I'm having to do this in DCS. I turn on OpenTrack's UDP tracker, turn on the FreePIE script, and then turn off OpenTrack's tracking.

Code: Select all

        public void Write()
        {
...
            local.CamWidth = 1920;
            local.CamHeight = 1080; 

The reason why it doesn't work is because FreePie doesn't set these two variables on FreeTrack protocol.

[CyberVillain]

aha, will check that out

[CyberVillain]

Does this version work?
