Cool stuff!

I guess this could be used to replace the function of the vr920 yaw axis as well then?
I have a problem using the native yaw due to the building i'm in being very well isolated....so the magnetic north thing isn't working at all.

I won't get the 6DOF though, but it should be possible to set up the pitch and roll with the native functions, and the yaw being controlled via the wiimote right?

Nope, unfortunatly not.
The Wiimote doesn't detect Yaw, so you'll have to find a different way to replace the VR920's yaw :/

Aaaah! I just assumed it would be something similar to the way TrackIR is working

Hey fellas, nice work!  I haven't messed with the wii remote at all so my question might sound silly but what is the sensor bar connected to?  I have a wireless sensor bar as well as the one with the wii and the remotes..

Is the glovepie software needed for this to work with FPS games and racing.  Carl, you said that you can use many remotes? Give some examples if you can as for a setup.

Also Carl  contact me e-mail  at kuchelsea35@yahoo.com  I have some things needed if you got time and paypal

More on this tracking setup!!

How many sensor bars can be connected to the PC? Could a setup allow for 360 deg, sensor in front, left,right and back or would these be the wii remotes? To bad there couldnt be a sensor bar shaped like a halo and out on the head so the remotes can detect it from any positon. Very good for even walking forward alittle and strafe or duck and jump, just make sure you are safe for wandering off  LOL...  ltr

Hi,

With the recent release of the freetrack 2.2 http://www.free-track.net/english/ almost 5 days ago, one wiimote, freetrack program, one IR led and VR920 work great. Perfect combination for the 6 dof. If you have problems in yaw with the vr920, or you want vr920 as just a display device, make a cap with three IR leds as in the link below, in 180 degree, you have 6 dof. I've tried thsi concept and it works perfect.

Stickied. I have a weak spot in my heart for pictorial walkthroughs. Great work!

I was fortunate enough to have a NaturalPoint TrackIR3 with the Vector Kit.  It already had 6DoF.  I was PLEASANTLY surprised when I jumped into rFactor and both the tracking from the TrackIR AND the tracking from the VR920 were supported.

I don't know how tracking was prioritized (ie two tracking devices, which one would the app 'listen' to first), but it just worked.

- When I was facing forward (or near forward) the track IR took precidence.

- When I turned out of the TrackIR's range, the VR920 took precidence.

- When I faced forwad again, the TrackIR took over.

The only thing I tweaked (and that was before I launched the game for the first time) was the "Amplification" of the TrackIR's panning motion. I set it to 1:1 roughly.


Bam.  I could now zoom in an and out!

Just read a few posts in here and just to clear up some confusion!... The Wii sensorbar actually has no sensors in it at all, its just two infrared LED's. Inside the wiimote there's an infrared camera which uses the position of the infrared lights on the 'sensor' bar to gauge its postition in relation to the infrared light source(sensor bar) its this information that is relayed back to the computer via bluetooth. The sensor bar is completely passive so all the sensorbar needs is a 12v powersupply to get the led's to illuminate independenly of the wii (USB is 5.5v so thats not viable without replacing the LEDS for lower voltage ones or making your own bar). So there you go :-) the sensor bar doesnt need to use any communication with anything other than sit in front of you and your wiimote :-)
Additionally for the Wiimotes to be able to communicate with the pc they require a Bluetooth adapter on the PC (yup youe computer will detect them as an Human interface device). Then the PC needs some software to emulate the signals recieved from the wiimote as mouse movement/joystic input etc...thats what glovepie is used for. I have quite a few glovepie scripts written up to use the wiimote along with the VR920 and will hopefully post em as soon as I have a chance to test them properly although im using the wiimote as a rifle and the the vr920 as the head tracker. all going well I'll have the scripts and how-to's posted up on our new VR fansite at www.vrgamer.co.uk next week.

I had thought using a sensor bar and wiimote could work in conjunction with the VR920 in Glovepie for 6dof, but didn't think seriously about it until I saw this thread.  Thanks for the info and the script.  I got a wiimote and one of the wireless sensor bars on Amazon.  I chose an Intec sensor bar that is shorter than standard for only $10, but it briefly loses connection sometimes so maybe another brand would be better however I don't know because I don't have a wii. 

I got Stefan's script working with Glovepie 3.0 and Live For Speed but the Z axis didn't work until I changed the script to use wiimote.z.  After that worked, I went ahead and used wiimote.x and wiimote.y as well, which are okay except that the wiimote calibration doesn't seem to work.  I got around that however by adding offsets to x, y and z for the initial cockpit view since my monitor is raised kind of high on a desk mount and I've found that the FOV of the wiimote is small so the head tracking works better with the wiimote positioned over a meter away.  I've used a mic boom stand to hold the wiimote behind the monitor peering down at the sensor bar mounted on a baseball cap with rubber bands and paper clamps.  Here's the script I"m using for LFS:

FakeTrackIR.yaw = vr920.Yaw

FakeTrackIR.pitch = vr920.Pitch

FakeTrackIR.roll = -vr920.Roll

FakeTrackIR.x = (Wiimote.x*1.5)

FakeTrackIR.y = (-Wiimote.y*1.5)

FakeTrackIR.z = (Wiimote.z*1.5) + 2

I bought 3 IR LEDs and a resistor from RadioShack yesterday and intend to make a 3 point tracking system to clip on a cap.  Hopefully it will work with Glovepie or Freetrack.

Does anyone know how to manually calibrate the wiimote without a wii?
