As I mentioned upthread, there are devices *today* that have all 6 degrees of freedom built into a one-handed controller (see 3dConnexion
). It's quite intuitive, I use one of their products for work every day. Just twist or push/pull harder or softer to control the rate of movement.
However, I was wondering if anyone knew what actual spacecraft, like the Space Shuttle or Soyuz, use for their control systems? I've been able to find pictures of their controls, but nothing that explains how they're used yet.
