A high-performance, compact, finger-operated pointing device comprises a body ( 34 ), a base ( 32 ), and return members ( 48 ). The body has integrated input elements ( 52 ). Finger-engaging elements ( 26 ) allow operating fingers to move the body and manipulate the integrated input elements simultaneously. Sensors ( 38 ) translate the body's movement to positional control signals to control positions of a computer controlled target. As an isometric device, the magnitude of the positional control signals is mapped to the moving speed of the target.
