1. A force-sensing data input device for use with a visual display, comprising:

  • a rigid member including a flange portion, side walls extending from said flange portion and an arcuate transparent faceplate joined to said flange portion via said side walls and generally recessed from said flange portion;

    a rigid mounting frame having a central opening for receiving portions of said side walls and said recessed faceplate therethrough, such that said faceplate may closely follow the surface contour of said display and said flange portion confronts said rigid mounting frame;

    a plurality of force-sensing means, each being disposed at a respective predetermined location between said rigid member flange portion and said rigid mounting frame, said force-sensing means holding separated said flange portion and said rigid mounting frame;

    said force-sensing means being positioned in wells formed in a side of said rigid mounting frame facing said flange, in a manner such that at least interference-sensitive portions of the same are effectively shielded from stray electromagnetic radiation, said rigid mounting frame being formed of a conductive material; and

    spring means for urging said flange portion and said rigid mounting frame toward one another.
