An improved formed lighting fixture having a frame, a light source, a cover layer coupled to the frame, and a fibrous layer coupled to the cover layer, in which the frame is formed by gathering a plurality of rods and profiled in a specific contour, the light source is configured to provide light from inside the frame and out through the cover layer onto the fibrous layer. A touch applied to a node of the panel changes a capacitive coupling between two electrodes of the touch panel. An algorithm suited for the diversity case and an algorithm suited for the non-diversity case are utilized.
