Connecting paper to the Internet.
Design, build and assembly of six paperclips that allow paper to connect to the Internet with conductive ink buttons.
Sales of traditional printed media are declining year on year; digital platforms are gaining more and more readers but not replacing revenues. Publishers are looking for new revenue streams and trying to attract younger readers.
The brief was to create a robust pre-production prototype to demonstrate to publishers an effective way of using paper electronics as a platform to bring in younger readers and increase revenues. Building on the thinking behind Postcard Player, we agreed that we would create a piece of hardware that the paper could dock into for connectivity, rather than integrating the conventional electronic components on to the printed substrate.
I worked collaboratively with a steering group from the University of Central Lancashire. We began with concept design and created user experience storyboards for ten different types of published content, from cookbooks to maps. We then selected three publishing ideas to develop, and identified leading national publishers in the UK to provide content and act as a sounding board for the development.
My first prototype was a paperweight that sat on top of printed media and used the weight of the object to make the connection with the ink. This was tested with a user group at the European Patent Office. Feedback suggested that the paperweight was too hard to keep in place, and as soon as a button was pressed the alignment between the object and the print was lost.
My next prototype was based on a paper clip or bookmark and used pogo pins to connect to the print. A bottom layer on the clip created an interference fit on the edge of the paper in order to apply gentle pressure against the pogo pins where it docked with the conductive ink. Built using Electric Imp as a connectivity solution, I wrote code that interfaced with a MPR121 sensor to detect capacitance changes when buttons were pressed on the ink. The software then sent a JSON post to a server which played an audio track on any connected device. An addressable RGB LED acted as a simple user feedback mechanism to show when a button was pressed.
I produced six working prototype devices and managed the production of the casings and the print. I was responsible for concept design, development, 3D design, and the hardware and software design throughout the project.
