Vuzix is still not supported in 0.45
Kinect support seems very similar to the raw Kinect API. In other words, it mostly just seems like a bridge between the Kinect function calls and GlovePie variables - which is not necessarily a bad thing. It just means that there is a lot more scripting involved to turn body motions into commands. I'm not going to pretend I'm an expert on GlovePie scripting, but Carl does provide a few sample scripts that show how to turn simple motions into commands - stuff like moving your right arm out to turn right, crouching to crouch, etc..
He also makes mention that GlovePie may not remain free, and if so Kinect will be thrown out because of licensing. So maybe we should think about an open source alternative to GlovePie to include popular hardware that is being left out. I admire the guy and there is a crap-load of hard earned R&D in the product that would be hard to duplicate, but if he is not going to support the community then we might have to support ourselves.
(Unfortunately the OpenPie project looks pretty sad and lonely right now)
