Hey Spectra, thanks for checking in. I have plenty of room to play and can move freely about my green box in YSF.
I re-tuned the Kinect device and still have the same problem. What I have noticed is that the lower 1/4 of my shoes/feet disappear into the floor. I also noticed this when re-tuning the Kinect through the Xbox...My feet were the same bright yellow as the floor (as the Kinect sees me, not that I have bright yellow shoes and carpet), so perhaps that is the problem.
Maybe I should try putting down a black workout pad or something on my carpet to help it distinguish between my feet and floor??
I am experiencing the issue with my feet appearing to sink into the floor. It does not at all seem to effect the way the game works for me. In my case it just seems to be an odd visual quirk. The depth of my play space is barely acceptable - a tiny bit over the minimum stated for Kinect. Sometimes, for example with back lunges, I have to start at the very front edge of the play space to do the exercise. But the games still tracks my feet just fine.
