Hi everybody,
I'm building a 3-point-cap to use freetrack with my Vr920 goggles (and get extra 3DOF) - i intend to use it for FPS games like "Crysis". My question is..how adaptable is freetrack to use with 3d Goggles? Will i be able to rotate at least 180º? The Vr920 uses magnetic sensors for Yaw..and in my experience the sensors are not very good - the image shakes a lot with games like "crysis"... I will aparently have to use a program called "Glovepie" for mouselook emulation - is this required? Any comments will be welcome. Thanks in advance.  |

Hello AlexandreSemed
No. The whole setting of freetrack is based on the fact you'll have to look at your screen while turning your head, so the hardware allows only 'small' head movements (usually a max of about 80° is good) and the software converts these 'small' real head movements in 'virtual' large head movements. A single webcam tracking is usually unsuited for large real head movements, unless you use a rather complicated tracking and dots setting take a look here for an example But as said , it's beyond the scope of the general purpose of freetrack. At now the best way to track a 1 to 1 (real head movements= virtual head movements) movement is to use gyroscopic tracking or accelerometer based tracking
 That means you're trying to use a headtracking device with crysis To my knowledge, crysis isn't compatible with headtracking (if i'm wrong , please correct me  )Thats means you use your headtracking prog as a mouse in your program, to move your character ??? IMO, that must provide weird results ..... The only FPS game which handles correctly headtracking at this time is ARMA
Depends of you VR920 driver software. I'm no glovepie user, so i can't answer about that. But i'm sure somebody will drop in and let you know. cya |

Hello AlexandreSemed
I took a look at the vid and noticed the following : - at 0:52 , the guy turns completely the visor (about 160° to the left) and the system continues tracking , alhtough it's obvious the wiimote can't see the leds anymore. - in the comments the guy says : 6DOF within wiimote sight, 3DOF otherwise. so IMO : This guy (really clever  ) has configured glovepie such as :- if glovepie gets infos from the wiimote, it uses the wiimote infos (6DOF) - if glovepie gets no infos from the wiimote (leds out of sighting range), it uses the gyroscopic infos from his visor - as long as the leds are in view, the wiimote info is used to recalibrate the gyroscopic system, so the 2 systems can work together. The best thing to do is to ask directly this guy because i don't know glovepie well enough, but its what it seems when looking at the vid.
Is it a "real" headtracking ??? that's : you can run in a direction while aiming in another direction while looking in a 3rd direction. If thats the case , it's a real ingame headtracking. If it's not the case (ie : headtracking moves your aiming point), then it's only something like a mouselook option. At this time , to my knowledge, only ARMA and the Insurgency mod for DOD:S allow real headtracking |

Those damn chickens..they have some sort of pentagon top secret gyroscope inside their heads!!!
