Hi all,

I wonder if any of you have experienced interference between TrackIR and E-Dimensional wireless 3D glasses?

Basically when I have both turned on then the mouse cursor jumps and the shutter synchronisation is lost.

If I cover the trackIR unit with my hand then the glasses start working again (whether or not the LEDs are off), and if I turn the e-Dimensional glasses off then trackIR works perfectly.

In the hope that it was interference between the IR LEDs for trackIR and those used for e-dimensional I build an active IR source into a baseball cap. No Joy.

I'm at my wit's end!

can anyone help?

lo

All i can tell you is....I dont have the E-Dimensional wireless 3D glasses but i do have the Elsa Revelator wireless 3D glasses. I can use them with TIR with no problems using a normal reflective dot. My infra red emitter is stuck on top of the TIR unit and out of the TIR`s view and not anywhere in front so that you have two extra active dots! If i find any more info on your problem i shall let you know asap. GL!

Red,
I have the wired E-D glasses and Track IR; they both work perfectly together.
I would suggest that the IR signal from the E-D unit is confusing Track. I bought the wired versions exactly for this reason.
Have you tried looking in the advanced window of the Track interface to see what the Track unit is 'seeing' while the glasses are active.
This will show where you problems are. Quite how you get round it though......

Hello:

This sounds like a classic case of IR interference. Should be able to fix it by looking in the Advanced Settings window, as already wisely pointed out. I know that this must work in some sort of configuration as eDimesional sells a ton of our units bundled with the glasses, some must be the wireless version.

Thanks for your replies all - IR interference does seem to be the problem.

As I mentioned above, I have now tried turning off the IR LEDs and the filters. With my baseball cap IR LED the system is 100% reliable *until I switch the 3D goggles on*. Now, I have mounted the LED on top of the baseball cap peak so direct illumination of the receivers on the glasses by any LED involved in trackIR is impossible, and looking in the advanced screen I see a nice round clean signal.

The only diagnostic step I can't take is to look at the signal with the 3D IR LEDs transmitting, since I can only see the advanced settings view while at my desktop, not in game, and the desktop isn't rendered in 3D, so there is no output from the "widget".

If anyone who has one of these devices can tell me how I might be able to invoke the 3D LEDs at the desktop so I can get a view of what TrackIR sees when the system is operating I would be very grateful!

I realise that naturalpoint don't make the 3D glasses, but e-dimensional don't even have a support forum...

Thanks in advance for all your help guys.

Oh, there is one other thing, even with just trackIR running, my frame rate in IL2:Sturmovik drops from 80-90 (XP2200+ with Geforce4 Ti4600) to 8-10! I'm assuming I'll find a fix for that somewhere in here so I'll go look, but I just thought I'd let you know.

Well, I have both the track-IR and the wireless ED-glasses, and I have no problem whith it...

The only thing I can think of is if you have the IR transmitter for the glasses in a possition that makes it send an beam to the Track IR reciever (or if you have a mirror on the wall behind)... But that's just a theory, as I said, I have no problems like that at all...
