Of course this would be good if you had video glasses. How about using 2 or 3 wii remotes pointed at you from different directions? This way when one LED drops out of the frame, it's just picked up by another camera? Or how about placing LEDs all the way around your head in a pattern FreeTrack will recognize. If an LED drops out the left side of the picture while a new LED appears out of nowhere from the right side of the image, then perhaps FreeTrack can assume that the head is continuing rotation beyond the angular range of the LED beam? Just some thoughts...

But this only makes sense if you use VR goggles. Look here for a multicam headtracker and here for a gyroscopic headtrack equiped vr goggle. (all commercial products, but just to show...) cya Edited by tristan68 on 13/02/2008 at 23h58.

I think it's fantastic to be able to track my head 360', too. but the problem of the 360deg-tracking is a sight of the cam. right? but think this, how about a cam on ceil or somewhere upper side of your head. and now there is no problem of sight of a cam to track your head. dissymmetric position of LEDs make 6DOF able ( I can't understand y-movement in this situation, but the FT can recognize z-movement ) I hope some developer will add this to Free Track later.

Class : Webmaster (admin) Posts : 930 Registered on : 09/07/2007 Off line Www	FreeTrack work on maximum 180° on all axis ! because in real life, if you move your head you can't do more than 90° on each axis ! It's not impossible to do 360° in freetrack (if you modify source code), but it's not interresting for gaming experience ... Edited by babasior on 26/03/2008 at 20h53. Babasior.

Class : Apprenti Posts : 2 Registered on : 26/03/2008 Off line	Right. I can't turn my head more than 90' on each axis " in front of computer to see moniter." . but someone have HMD(head mounted display) is interresting in 360' tracking for 1:1 movement. that's more realistic than now. and if Freetrack will be developted in these way, it is more useful in games and somewhere out of game.
