Abstract

Sketching is viewed as an efficient way to design the user interface. However, there are few tools that help designers go from sketching the user interface to simulating its behavior with endusers during early evaluation. We have developed a pen-based tool called UISKEI, which goes beyond allowing designers to define simple navigation between user interface snapshots, into allowing them to define more complex interactive behavior with conditional changes in the state of the user interface. We have conducted two studies on how UISKEI compares to similar prototyping techniques: paper and pencil; widget-based (Balsamiq) and other sketch-based user interface prototyping tools (DENIM and SketchiXML). The studies revealed that UISKEI's sketch-based definition of the user interface behavior for later simulation is better than the analogous mechanisms provided by the other tools.
