A lot of people still rely on pen and paper for taking short notes. Post-Its® are still the most popular paper media for informal note taking. In this paper, we present the design and implementation of Move-It, a system that combines the affordances of note taking on paper with the capabilities of computer systems. Furthermore, we present how common Post-It® notes can be actuated by shape memory alloys, thus become interactive sticky notes giving active physical feedback. Keywords pen-and-paper, sticky notes, digital pen, informal note taking, shape memory alloys.
