Disable camera view in ARToolKit while continuing to track marker positions

Hi, I am using ARToolKit to make a platformer and basically use markers held/worn by user as mouse pointers. So its not your typical AR game where you need to display something on top of a camera image.

I just need image for tracking position of markers and taking in-game decision based on xy coordinate of the marker on camera screen. The actual graphics window will be purely in unity 3D world with no element from camera being shown in the scene.

So how do I turn off the camera view while still continue to get the marker positions, if that is even possible?

 

did you solve the problem?
