I'm not really sure myself how they navigate a space walk, but I watched
Vance Brand and several other astronauts navigate a mockup of the
Teleoperator Retrieval System (you know, the one that was supposed to save
Skylab) about 4 years ago.  We programmed the worst case coning motion into
the Skylab, and those people could hit the docking ring without hesitating,
time after time. (The TRS was a rocket motor carrying a TV camera and a
docking ring, controlled from the Shuttle flight deck with two joysticks
for 6 degree-of-freedom control.) The champion at the time was the
astronaut who was pilot for the US-USSR docking - seems he spent a year
with the controls glued in his hand.  Since most TV games have two degrees
of freedom, I guess you can see the point.
