We haven't distributed any game controller support in Chimera. Conrad
Huang in our lab recently tried head tracking with a Wii remote. We've
tried Wii remote control of Chimera using just mouse emulation. We've
tried a force feedback device called a Phantom (from Sensable) for
placing markers in density maps. That was distributed with Chimera on
Windows in the past but is not currently working, though I am just now
fixing it. Greg Couch in our lab has experimented with a game pad API
and a consumer device.
So we have some interest in alternative input devices but it is mostly
just in the tinkering stage.
