1. An interactive information display employing capacitative proximity sensing means in order to respond in a specific manner to a viewer in proximity to the display (the “

  • proximate viewer”

    ) wherein the display includes (a) visible indicia laid down upon a substrate (herein called “

    a poster”

    ), (b) a replaceable non-conductive substrate (herein called a “

    customized sensor-bearing substrate”

    ) bearing a layout of at least two conductors;

    (c) each conductor terminating in one of at least one pair of areally enlarged, closely apposed yet separated conductors (herein called “

    electrodes”

    ) that serve to spatially localise a proximity-sensitive field, the at least one electrode pair being located within at least one selected area in relation to the overlaid poster when the customized sensor-bearing substrate and the poster are mounted together and providing, when in use, a localised proximity-sensitive function capable of being identified with a localised part of the poster selected by the proximate user, (d) at least one disconnectable connection means capable of connecting the customized sensor-bearing substrate to at least one non-replaceable charge transfer controller, capable of using the at least one electrode pair as a localised proximity sensing means, which controller in turn is connected to (e) at least one non-replaceable output device capable of selecting and sending a communication, based on the content of the selected area of the poster to the proximate viewer.
