Abstract
A controller including a first control member, a second control member that extends from a portion of the first control member, and a third control member that moves in conjunction with, and in opposition to, a degree of freedom of the second control member. The third control member is configured to be operated by one or more of the non-index fingers of the user's hand. A controller processor is operable to produce a rotational movement output signal in response to movement of the first control member, and a translational movement output signal in response to movement of the second control member relative to the first control member. In exemplary embodiments, the first control member may be gripped and moved using a single hand, and the second control member may be moved using the thumb of the single hand. The third control member is configured to be operated by one or more of the non-index fingers of the user's hand, thus permitting intuitive, single-handed control of multiple degrees of freedom, to and including, all six degrees of rotational and translational freedom without any inadvertent cross-coupling inputs.
