Ok I just watched all of your demo videos again. Like others have pointed out, this is for power users. The basic usage is complex enough, you have a TON of other features.

A good demo video of someone using an app in an everyday situation, clearly showing them holding the phone in one hand (not keeping it on a table), will really help showcase padkite's power.

You've clearly built some amazing tech, but you need to educate people on how to use it. You should seriously consider making a game which uses these gestures, so people learn the gestures while having fun.

The Wii primed people for the Kinect.
