How to Limit Max Angle of trackIR to prevent flickering?

[CommandT]

Hey folks,

 

So I've spent a few days playing around with trackIR curves. I've watched every youtube tutorial (Spudknocker/ Jabbers/ Ralfi etc) and I have the actual head tracking set up to an acceptable level I think for how I want it except there is one slightly annoying issue I cannot seem to rectify.

 

Occasioanlly I raise my head to look up a little too much where one of the reflective strips gets blocked and trackIR looses signal (this is already after reaching the 180 deg tilt limit) but the annoying thing is that instead of trackIR simply freezing in it's last know position it flickers to another angle fairly quickly and it becomes both annoying to see and also slightly disorientating. Is there any way to prevent this without the obvious solution of not lifting your head so much? Problem is it's a bit too easy to tilt your head a bit more than needed especially when you are wanting to do a quick glance up.

 

P.S. I have the "limit" boxes ticked on the curves in trackIR software.

 

Cheers!

I am using the other clip-on sensor so I hope my experience will apply. First I have a couple of months ago radically increased the slopes to give more display movement per degree of head movement. So I don't need to move my head as much to get the display movement I want. This is in pitch and yaw axis. To make this a little easier to deal with I have a dead zone of about 7-8 degrees head movement before the display moves. This allows some inadvertent head movement to be absorbed before the display moves. Also I find the position of my headset (that the sensor is clipped to) is critical. I adjust it while in the TIR page before I start a flight. In pitch I can go a little more than 180 deg of display movement up and maybe 100-110 degrees of down movement. If the headset isn't placed on my head properly I lose some off the end of either up or down travel.

This is pitch.

Notice I have a lot more 'up' than 'down' curve.

Here is yaw. This shows 2 things.

1- Note on the chart at the right I show 7.2 deg of yaw head movement (raw) and just 0.2 deg of 'game' movement

2- You can see my yaw chart at the left. I use a couple of clicks on the green 'UP' arrow, move the little circles some and then do a couple of clicks on the down arrow to move it back down.

With this curve I can look a couple deg more than straight back, maybe 190 deg in both directions.

Finally here is roll. I found I apparently inadvertently lean my head sometimes so I have very little roll movement curve or the view goes crazy.

Edit to add. I don't have the 'limit' box checked and have never tried it.

Ah many thanks for this. I actually used a little idea from your pitch curve and it works well for my own set up. Cheers!! Is there an advantage to having the Track Clip Pro that attaches to the headset instead of using the standard set up on a baseball cap?
