(Books can talk) This is a system dedicated to the readers who would like to find the most suitable book for them. At the end of each book of the system it is possible to find a blank card where the user could (hand)write his hown thoughts about this book. The card is not just a card, it hides more functions: writing on a special surface, the text will be converted directly from analog to digital, in this way the comment will be available for all the costumers of this bookshop. In the library you will find a big visualization made with undreds of cars, related to all the book in the library. On the card’s back there is a tag that, when passed on the reader, allows to see all the comment of this specific book.
