I like your benchmarks. Your 2x2s compare various products in many different markets that still relate to your idea.
I wish your gesture recognition idea considered Xbox Kinect sensors. They are fairly inexpensive and I found in my benchmark research that Cornell students used them for their robot.
What if your gesture control was paired with your dome idea? A user could control the experience on the dome with gestures, avoiding possible misplacement of a remote in/under the bed.
