I think eye tracking will be needed to make any of this work in any way that is really acceptable to the vast majority of end users - look up at a menu bar, it highlights the "tabs" you are looking at, look for a second or two and it selects that drop-down, you scroll down with your eyes and make a selection the same way. Good for answering or rejecting an incoming call, opening a book or video app, etc..
Wireless connection to a keyboard and mouse would further extend its capabilities.
