Flight Profile problem

[Euripides]

I am using TrIR4 with Falcon 4.0 AF and OF with satisfactory results but for this:

Everything works nice and smoothly as long as I am looking to the front half of the cockpit [i.e. looking upwards up to the top middle of the canopy] If however I pass this point (head movement all way backwards) and I turn my head left, the x axis will turn right and vice versa. It is as if the axis becomes inverted as soon as I look backwards via a "head back all the way" move.

Any suggestions?

What version of the TrackIR software are you using?

[Euripides]

TR-IR 4 version 4.1 built 37

You understand the description:

When moving head all way backwards and then right (do it and you will end up looking back right) the software ends up as looking back right - it confuses the head turn if the turn is initiated after looking vertically up.

and you have the true-view option enabled?

[Euripides]

yes

uncheck the box

I did but the behaviour is exactly the same.

Looking at the "heads" movement and assuming that they are meant to represent actual head movement I think I know the basis of the problem. Looking at the heads it seems that the movement is (wrongly) modeled as if the axis of yaw is the front of the neck while the true axis of movement of a head should be the back of the neck - ie the spinal cord. The result is that when the look turns right the head is positioned in the left hemisfere looking right. This results in inversing the axis when yaw is applies when already pulled back

I will post a video on youtube to describe the behaviour graphically

Any ideas about a solution?
