Force feedback control wheels and knobs

摘要

A knob controller device comprises:
a knob coupled to a grounded surface, said knob rotatable in a rotary degree of freedom about an axis extending through said knob, said knob also moveable in one or more of:-
• a transverse direction approximately perpendicular to said axis;
• a linear degree of freedom approximately parallel to said axis;

a rotational sensor that detects a position of said knob in said rotary degree of freedom;
one or more of:-
• a transverse sensor operative to detect a position of said knob in said transverse direction;
• a linear sensor operative to detect a position of said knob in said linear degree of freedom;

and
an actuator coupled to said knob and operative to output a force in said rotary degree of freedom about said axis.
