The design of a GUI paradigm based on tablets, two-hands, and transparency

AbstractAn experimental GUI paradigm is presented which is based on the design goals of maximizing the amount of screen used for application data, reducing the amount that the UI diverts visual attentions from the application data, and increasing the quality of input. In pursuit of these goals, we integrated the non-standard UI technologies of multi-sensor tablets, toolglass, transparent UI components, and marking menus. We describe a working prototype of our new paradigm, the rationale behind it and our experiences introducing it into an existing application. Finally, we presents some of the lessons learned: prototypes are useful to break the barriers imposed by conventional GUI design and some of their ideas can still be retrofitted seamlessly into products. Furthermore, the added functionality is not measured only in terms of user performance, but also by the quality of interaction, which allows artists to create new graphic vocabularies and graphic styles.
