I think that instead of projecting an image of the whole controller or keyboard, maybe if it just had an un-intrusive representation of one or a few of the buttons, enough for you to locate and get your hand on it without it interfering too much with the display, that might be helpful. The video says you can make your own 3d models, so this should be possible, hopefully without a graduate degree in 3d modeling. Also if you can turn it on and off, maybe with a voice command, so that it only shows when you need to find something, also good. Still not for me, and I have no plans to own any headset that is compatible with it anyway, but it will be fun to watch how this tech develops.
