I have noticed the limited space with Kinect (or even two kinects), when using iPiSoft for motion capture, although iPiSoft supported backwards facing, just buggy. However, some sort of body tracking to compensate for the WMR limitations would still be nice, even if it’s front facing only.
I’m not sure if this is asking for too much, but how about using the WMR orientation to determine if you are facing backwards? Just tossing ideas.
Either way, I’m glad you are going to support WMR. I can’t wait to see what you can come up with. People like you are making the full VR market accessible to more people, and that’s a great thing.
