I heard an interview over the weekend on the use of robots in war. A fascinating bit from that story was that as modern warfare moves to soldiers manipulating robots from afar, the military leveraged the existing research and development of game companies in the design of hand held controllers (at 13:43 in the streaming interview).
So the predator drone remote control probably looks very similar to your PS3 or Xbox controller! It makes sense as both tasks are nearly identical (as far as I can tell).
It was also interesting that the 19-year old Army specialist who trains remote operators honed his skill by playing video games (at around 14:30 in the interview).
Related, the Designing for Humans blog has a great, multi-part series on the ergonomics for interaction designers. Part 3 is very relevant to hand held controller design.
