Euler diagrams form the basis of various visual languages but tool support for creating them is generally limited to generic diagram editing software using mouse and keyboard interaction.  ...  This paper presents SketchSet, the first sketch tool for Euler diagrams whose curves can be circles, ellipses, or arbitrary shapes.  ...  EULER DIAGRAM CREATION AND EDITING SketchSet allows the user to create Euler diagrams in two ways: via a sketching interface using a stylus or via a formal diagram interface using more traditional point  ...

Combining Sketching and Traditional Diagram Editing Tools

Gem Stapleton, Beryl Plimmer, Aidan Delaney, Peter Rodgers
2015 ACM Transactions on Intelligent Systems and Technology  
Yet there is also a need for more formal visualizations, that is diagrams created using both traditional keyboard and mouse interaction.  ...  The least cognitively demanding way to create a diagram is to draw it with a pen.  ...  Vertices are added by tapping while the pen barrel is button down or holding the pen down for an operating system defined time. Edges are created by dragging the pen along the edge path.  ...

Structure Editing of Handwritten Mathematics

2014 Proceedings of the Ninth ACM International Conference on Interactive Tabletops and Surfaces - ITS '14  
The editor is made available in the form of a C# class library which can be easily used to extend existing tools.  ...  We describe some of its most important features, including the use of gestures to manipulate algebraic formulae, the structured selection of expressions, definition and redefinition of operators in runtime  ...  associated with them; and SketchSet [23] , a sketch tool for Euler diagrams whose curves can be arbitrary shapes.  ...
