Model, Methods, and Tools for Supporting Multi-fidelity Prototyping of Graphical User Interfaces

Mixed-fidelity prototyping consists of mixing simultaneously or not various fidelity levels within the same user interface prototype. Multi-fidelity prototpying incorporates mixed-fidelity prototyping in that it enables the designer to express any interaction object in multiple fidelity levels and to ensure a smooth and dynamic transition between these levels at design-time. The multi-fidelity approach allows integrating user interface elements delivered in one or many fidelity levels in order to build a user interface prototype which evolves as the interactive application development life cycle is progressing. This paper presents models underpinning multifidelity prototyping. Design methods relying on these modes are defined and various software tools supporting these methods will examplify their application.
