Abstract

In one aspect, the invention includes a fader controller comprised of a longitudinally extending track having a portion thereof extending over an image area of an electronic display, and a fader cap joined to the track for longitudinal sliding translation therealong. A plurality of permanent magnets are spaced along the track, and the fader cap includes at least one electromagnet. Conductive rails extend longitudinally on the track, and the fader cap includes contacts that electrically engage the conductive rails. The electromagnets are actuated to translate the fader cap distally or proximally along the track. In another aspect, the invention provides a magnetic arrangement for removably joining one or more controller device to a flat panel electronic display, whereby controllers such as switches, knobs, and faders (slide controllers) may be superposed on the display.
