Headtracking with VR920
I got to try out the headtracking with a VR920 and it was not jittering a lot when using CarlCenners program.
My question is, wheter we made something wrong.
If it's common maybe add a bar for some small delay depending on the game and the performance of the machine. If you would wait 0,1sec and make the middle value it should cancel out some of the jittering.
Does anyone know more about that?
Maybe you, Carl?

Made something wrong with what? I don't understand.

No I think it was with Vizuix original driver some time ago...
And it was going left and right all the time, even when my head was still.
Maybe I used the wrong word:
- tremor
- shiver
- jitter
- quiver
- waggle
Well it moves more than the head and if some latency was added - maybe with a scroll bar from 1 to 1000ms - it could reduce the movement. And everyone can choose a latency depending on game and personal opinion.

I heard GlovePIE can be used for the translation of head movement to mouse movement of the VR920 and that software supports filtering out small movements (like the constant left<->right shaking, which happens because that axis is taken with a compass).
Still waiting for mine to arive, so I couldn't try it out yet.
And I have no clue what CarlKenner's programm is, but if it is software to translate head movement to other movement, then it should support an input treshold because compasses will always shake a bit to the left and right.
I hope I understood the problem and was of some help...

You can do almost anything imaginable with glovepie. I highly recommend you to read the documentation (the 'preliminary documentation').
I don't understand very well your explanation, but it looks like you may want to smooth out the values. You should use:
'x' is the value you want to smooth out. As you can see, you can tell how many frames (glovepie iterations, not game frames) you want to use for the average calculation (but more frames increases lag, of course) and you can also set a dead band. Handy for noisy inputs.
A basic use would be:
If you want to change glovepie's frame rate you can use the PIE object like this:
You may want to create a separated script for each game to account for each game's peculiarities. It's common procedure for me.
I don't understand very well your explanation, but it looks like you may want to smooth out the values. You should use:
Code: Select all
Smooth(x, [ExtraFrames, [DeadbandDistance]])
A basic use would be:
Code: Select all
mouse.x=Smooth(vr920.Yaw)
Code: Select all
PIE.FrameRate=50Hz

GlovePIE is one of my programs. I also added head-tracking to Assault-Cube (and support for every stereoscopic format EXCEPT iZ3D, because iZ3D won't release their algorithm, and the reverse engineers have been slacking off). In Assault-Cube I used much fancier filtering, with different amounts of filtering based on how fast you are turning, so for fast turning there is no lag. I haven't made an easy way of doing that in GlovePIE yet. The problem is that in addition to high frequency noise, there is also a slow sway from side to side, even when the VR920 is sitting on a table, but I managed to filter that out with tons of filtering (like 200 frames) when you are not turning. I also added some very poor quality head-tracking to some other open source games.

Oh cool. I haven't worked on it for months, so I didn't notice.
Please send it to me at: carl.kenner@gmail.com

Thanks for all the explanations. I think it's what I was looking for. Unfortunatly I can't try it out myself, because I don't have a VR920 (or other headtracker) to try it out.
So you have to change some .ini or .config file and it's not in the menue, right?
Maybe it's a good Idea to share profiles for special games - if they are difficult to make. Or maybe include them as standard into the file to make it more easy for noobs to enjoy the prog
Thanks for all the Help
Exactly that is/was the problem I noticed. I'm not shure, whether it was high or low frequency 'swaying'. Well at least it was very anoying and deliverd nearly instant headache or at least discomfort - for not trained user.The problem is that in addition to high frequency noise, there is also a slow sway from side to side, even when the VR920 is sitting on a table, but I managed to filter that out with tons of filtering (like 200 frames) when you are not turning.

Try putting it inside a RAR file. Gmail is allergic to ZIP and EXE files.
