Sketching and evaluation of UI-scenarios using multitouch interaction with gestures.

Abstract

User interface designers are more important to the system development processnow than before. Thus it is more important for them to have a good tool fordesigning the user interfaces. Most professional designers start the rough sketchingand brainstorming on paper or on white board, as this gives them a lot ofcreative freedom. The downside to sketching on paper is that there is no goodmethod for displaying functionality is the sketches, and they are hard to save.This report tells you about some electronic sketching tools that already exists,and explains some different multi-touch technology.I will develop a prototype of an interactive multi-touch sketching tool for UIscenariosand use an xGOMS model to evaluate the UI s. The UI sketching toolwill be implemented on Samsung Galaxy Tab with Android 2.2 (Froyo) and thexGOMS will be implemented in Prolog.
