SketchGraph: Gestural data input for mobile tablet devices

Abstract

As tablets become ever more powerful and popular, people want to use them broadly, including for business applications like spreadsheet data graphing. Tablets are better suited to informal exploration through sketching, however, than to inputting data into a spreadsheet. It would be much more appealing, and suitable to the medium, to sketch a graph as if you were drawing on a napkin. We describe an early prototype to support a gestural, graphical interface for inputting and updating graph data that is as easy as drawing a few strokes. With it, users can focus on exploring their domain, rather than on the mechanics of data entry. © 2012 ACM.
