Despite all the attempts of modern information technology to supplant paper by sophisticated electronic devices, paper is still omnipresent in virtually any office environment. We have learned over the last decade that paper is an indispensable part of our daily work and that even the latest computers are not able to mimic its functionality. Today, paper and computer are coexisting side by side without interacting with each other, both having their specific advantages. This paper presents a concept for bridging the gap between computer and paper by combining the advantages of both electronic and paper world. The implementation described in this paper augments standard paper with features of modern information technology. Moreover, it allows interfacing computers using pen and paper.
