1. A hand-controlled mechanism for producing signals to move the position of a cursor in a computer display, the mechanism comprising:

  • shaft means having an elongated axis;

    a plurality of conductor means wrapped about said shaft means;

    drive means for applying an energizing signal to a sequence of said conductor means;

    cylindrical means mounted on said shaft means and moveable about and along said shaft means in both rotational and translational directions, said cylindrical means provided with conductive plate means which overlap a plurality of said conductor means, said conductive plate means acting to couple an energizing signal applied to a conductor means to other conductor means overlapped by said conductive plate means; and

    decoder means for sensing said coupled energizing signals and providing an output indicative of the position of said cylindrical means to accordingly control said cursor position.
