Love this idea. However 94% accuracy is not good enough. You need to be able to trust your action will lead to the desired result. 94% is like Siri getting your whole text message right, but getting the recipient wrong.
A lot depends on what happens the 6% of the time it fails. If failure just means that it fails to recognize that there was a gesture, then 94% is probably fine. It's not that big of a deal to have to gesture twice 6% of the time to turn off a light or skip to the next track.
Failures where the gesture is recognized as another gesture would be a lot more annoying.
