Abstract
A book spread identification arrangement for a board book is provided, the arrangement comprising a plurality of conductive paths, contact means disposed adjacent at least part of at least one of the conductive paths and processing means connected to the conductive paths and configured for processing signals associated with the conductive paths. One selection end of each path is disposed adjacent the spine surface of the book. The contact means comprise one or more conductive surfaces and are arranged, upon opening of the book to a spread, to contact one of a plurality of combinations of one or more of the conductive paths. Each of the plurality of combinations is in a predetermined unique association with a respective single spread of the book. From the processed signals, the processing means are able to determine the particular combination of conductive paths contacted by the contact means and identify to which spread the book is open.
