Sketching is an important activity for understanding, designing, and communicating. Often, sketches start on paper or whiteboards, are revised, and may evolve into a digital version. Users may then print a revised sketch, change it on paper, and digitize it again. Existing tools like EverNote and OneNote focus on a paperless workflow, i.e., archiving analog documents, not on integrating digital versions into the analog-focused workflow that many users follow. In this paper, we present the conceptual design and a prototype of LivelySketches, a tool that supports the "round-trip" of sketches from analog to digital and back. The proposed workflow includes capturing both analog and digital sketches as well as relevant context information. In addition, users can link sketches to other related sketches or documents. They can access the linked artifacts and captured information using digital as well as augmented analog versions of the sketches. We further present results from a formative user study with four students and outline possible directions for future work.
