A Post-Bit is a prototype of a small ePaper device for handling multimedia content, combining interaction control and display into one package. Post-Bits are modeled after paper Post-Its™; the functions of each Post-Bit combine the affordances of physical tiny sticky memos and digital handling of information. Post-Bits enable us to arrange multimedia contents in our embodied physical spaces. Tangible properties of paper such as flipping, flexing, scattering and rubbing are mapped to controlling aspects of the content. In this paper, we introduce the integrated design and functionality of the Post-Bit system, including four main components: the ePaper sticky memo/player, with integrated sensors and connectors; a small container/binder that a few Post-Bits can fit into, for ordering and multiple connections; the data and power port that allows communication with the host com-puter; and finally the software and GUI interface that reside on the host PC and manage multimedia transfer.
