YARA (Yet Another Re-Announcement)

About 1990, when I was teaching user interface to Commerce students, 
I did all the obvious stuff and then, as a circuit-breaker, told them 
about the games-helmets that enabled a (notional) rocket to be 
steered using 'brain-waves' - alpha or gamma was it, I can't remember.

That and line-of-sight and/or focus-based schemes were prototyped two 
decades ago for the immobile and the very busy (such as the pilots of 
interceptors), but I'm not sure to what extent such things have made 
it beyond warfare and games applications.
