The proposed research will develop the first techniques for recognizing sketches of Euler diagrams drawn by users. The proposal is for Dr Plimmer to travel to the UK team for 1 month as a Visiting Researcher and for Dr Stapleton to travel to New Zealand for one week. The research visits will facilitate the exchange of knowledge between experts in automated Euler diagram drawing (the UK team) and sketch recognition (Dr Plimmer, Auckland, NZ). This will allow an important exchange of information about relevant drawing and sketching techniques and result in further, significant, collaboration.A natural creation method for Euler diagrams is using a pen but no intelligent tool support exists for this mode of entry. Euler diagrams are a popular and frequently used visualization technique; in part, this popularity serves to motivate our selection of them for the proposed research, since the results are likely to have significant impact. Moreover, Euler diagrams form the basis of more expressive notations, built by augmenting them with graphs or arrows (or both), for instance. Example notations include spider diagrams, Euler/Venn diagrams, Venn-II diagrams, constraint diagrams, and ontology diagrams. The research results of the project provide a basis for developing sketch recognition tools for these more expressive notations. Extending the research results to these notations will be the subject of the future collaborations, between Dr Plimmer and the UK team, that will build on this project.
