A printed article (2) and electronic device (3) are acoustically coupled. The printed article is able to receive user input by touching an area or areas (4) of the printed article with their finger and output an acoustic signal (5) which is detected, decoded and processed by the electronic device. Thus, the printed article can be used to provide remote user input and/or data, such as a universal resource identifier (URI), to the electronic device. |
