Voodoosketch is a system that extends a graphical table top interface with physical palettes on which users can dynamically deploy controls as shortcut to application functionality. The system provides physical ‘plug and play’ controls as well as support for sketching of controls, and allows controls to be associated with application functions via handwritten labels. The system uses a special digital pen, which writes ‘real’ ink on the palettes and while functioning as a digital input device on the graphical work surface.
