Today I got my TrackIR3Pro, but didn't manage to set it up correctly until now. I am still studying the manual so maybe I will get it right with time.
However I have the impression that the reflective dot I use, interferes with my glasses which are also reflective of course (anyway it are reading glasses and not non-reflective) and gives erratic results.
Is there a solution for that ? ( I assume that TrackIR should also be usable for wearers of glasses )
Also: Do you have any suggestions where to place the reflective dot ? I use a headphone, but without a microphone attached
and I don't like to wear a cap while playing, nor to stick the dot on my forehead. I tried already to stick a little piece of plastic on top of the headphone band and the dot on that, but that seems not to work very well, probably because my hair masks the dot partially.

I use it while wearing glases and no problems.

The top of your head is a bad place as the dot hardly moves when you turn your head. It needs to be mounted forward somewhere. I clip on the front of your spectacles frame or the front of one of the arms, a pen mounted to the top of your headset and projecting forward, the peak of a cap, something like that.

I will testify that TOAD's method works great! And cheap, too! With a little imagination and velcro/tape/glue, one can improve on the flat dot. I guess the new Expanded Vector 6D contraption is NP's effort to do just that.

Hi,
I wear glasses for playing IL2 and have got it working fine now. I wear a baseball cap with one of my daughters toys sticky taped to the peak http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif The toy looks exactly like one of them kiddies lollipops i.e. 1" diameter ball stuck on the end of a 3"stick. I use one of the square larger patches. It works very well, the curved shape of the ball giving constant tracking when moving my head. Also because it's probably 6-7" away from my head it registers good movement. The shine from my glasses doesn't seem to effect it at all! I just look stupid! http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

I hate wearing a cap too, so i have a reflective ball attatched to a biro that is in turn taped to the top of my headaet.Works a treat,although my wife thinks i look a touch 'eccentric' when flying http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

All you need to do is stick one of the larger rectangular reflector patches to the centre of the brim of a baseball cap. I did that on day one and never had a problem.

I just turned my baseball cap backwards and stuck 5 close dots (flower-style) on the band. no problems. But obviously, give yourself a couple of weeks to adapt; it takes a little training with the head.

You soon learn to place your lights/curtains etc to reduce the reflections of your lenses.

Placing the dot as far forward as possible, as the others have said, is essential with glasses.

But biggest trick is to tune the detection filter to pick up your dot size, set the 'window' to match the smallest and largest sizes your dot presents (the closer the dot is the less the difference http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif) by turning your head through the extremes you will use.
That way it will ignore the odd errant flash of your specs.

I too wear glasses - I use a baseball cap to get the dot closer.

I don't have an IR3.... yet, just the IR2. I got the Tracker hat free when I purchased my Tracker a year ago. I also wear reading glasses and no problems with them and reflectiveness.

One thing I have found is lighting will cause it to go haywire once in awhile. I use a flourescent swingarm lamp on the top of the shelves on my desk, but adjust the light so it isn't picked up by the Tracker. Tracker is mounted on the top of my LCD screen. I found that to get the full range of movement, even with the hat I need to sit no further away than 18"s from the screen. Maybe with the IR3 Pro you can sit further away.

Excuse the mess. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

How exactly do you do that ? I read the manual and I think it has to be done in the Tracking Screen, but I can't figure it out. Could you explain this a little further ?

And: I got it set in a way that I can fly now, using a profile I was linked to in another thread. Of course I have to get used to using TrackIR, but is it normal in the beginning that your view moves rather erratically and that you have to get used to controlling your head movement in a certain way ?

I'll try to, as I have a lowly ver 1 and 2 not the Pro 3 http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif.

What I was describing has now been replaced by:

(available under 'Tracking' click the settings button:

'Preferred Object Size
This slider bar determines the preferred size (in pixels) of the reflective target for the TrackIR to track. The larger your dot, the greater the setting needs to be set to.'

Online manual reference is here:

Experiment with an increased dead zone. We naturally move our heads in anticipation of the screen view, It takes a while for this to be 'trained out' so the usual trick is to use a greater dead zone. After a while, once 'trained' http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif it is possible to reduce the dead zone.

Also experiment with the acceleration curve, slow (low) in centre and rising towards the extremes.

You have just embarked on a journey that will enhance your 'real' appreciation of a fine sim http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Thanks B16Enk, I think I am beginning to understand it now. But one more question:
So with TrackIR3, because you can't set a window, it would be best to set the slider to about the smallest pixel size (of the reflective dot) that it detects when turning my head to all the edges of the screen ?

I also wear glasses .
I got "disturbing" reflections from my glasses ONLY when I was looking STRAIGHT at the TrackIR unit , in other words , when I looked a little upwards .
Not when looking down , or looking high up .

So I had to find find a way of avoiding looking straight at the unit . The trick was to put the TrackIR unit 20 to 25 cm higher above the edge of my screen .
I did this by means of a small structure in wood .

The unit has to be higher then the highest point you look at while flying .

In this way , the Infra-red beam which is emitted by the unit will bounce off your glasses ,but without reflecting back to the unit , it will reflect downwards .

I used this for about 1,5 years , with trackIR 1 .

I now have TrackIR3 pro since a few months , and still use this system .

I recently installed the latest software , and took the opportunity to do some testing without the "elevated" position of the unit , in order to try to eliminate the wooden structure .

And guess what ? , the "disturbing" reflections started again , not always , but sometimes it goes bezurk .

I tried using the software settings , but in my case , it didn't work.
So went I back to the "elevated" position of the trackIR unit .

One more thing : in the beginning , when you're learning to get used to the TrackIR , I found it very helpfull to fly in aircraft with a metal framework-canopy , which acts as a positional reference .
It helps you to be better aware of the position of your virtual head in the virtual cockpit , it's easier to "know" where your virtual head is looking at .
Otherwise , you can easily get dis-orientated if you have no reference points or reference lines inside the virtual cockpit .

In other words , avoid flying in a "bubble" canopy in the beginning , and practice in something like a Zero , a Hurricane etc .

Not a P51 .

Later on , as you get more used to it , you can switch to bubble canopy's .

Have fun with trackIR , it rocks !

I have TrackIR2. I wear glasses...I put the Dot on the part that rests on the bridge of my nose.
I sit with that dot probably 20-22 inches from the screen. Daytime I close window blinds 80% as the window is behind me, off at my 5 O'Clock position.
TrackIR2 works pefectly for me.

My glasses are, however, very simple Reading Glasses(magnification only, cheap drugstore $9.00 per pair glasses). Perhaps more complex prescription glasses Would be more likley to cause some sorts of reflective 'bending/refraction of the TIR "beam-return"...Dunno bout dat.

Thanks again for all the input.
But SergeVE, your solution sounds great, but how about the centering of the tracking in the tracker screen ? I suppose you don't get the image of the dot centered that way, that is in the vertical axis ?

With the latest drivers you go to Tracking/Settings/then check the box for Light Filtering. Then adjust slider so all it picks up is your reflective Ball, on the tracking screen. Mine is 130 but I don't wear glasses.

Rijnton1944 ,

Start up the trackIr software , and open the "tracking" screen .
Sit in front of the screen as you would normaly do to fly .

Hold your head in a relaxed "center" position .

Adjust the BODY of the TrackIR-unit so that the dot is in the middle of the tracking screen .
( the bracket holding the body of the unit is a bit stiff , but the body can be twisted in 2 axes )

To keep the unit it its correct position , I have screwed the TrackIR-unit firmly to my home-build wooden fixture which elevates the unit .

I fly in a "locked" chair , so the position of my head in relation to the unit is always exactly the same , every day .
I think it is important to always sit at the same distance to the unit each time you fly .
Otherwise , the response will be somewhat different .

What do you mean by "locked" chair , I hear you think .

Well , the chair is mounted on 4 wheels ,and guided by 2 telescopic sliding bars normally used for kitchen drawers .
So , to get into my cockpit , I slide the chair backwards , sit down , slide the chair forward again , and lock it with a pin .

I don't like "climbing" into the cockpit you see - let alone climbing out of it , heavily wounded by flak-schrapnell .

I have always used a dot on my forehead , and now I'm experimenting with a extended cap , to enhance the precision .

Cheers ,
