In a previous article, I discussed using POP to create sketch-based clickthrough prototypes in participatory design exercises. These prototypes capture well the flow and overall layout of early design alternatives.
The same piece briefly mentioned another category of clickthrough prototypes: widget-based mockups that are designed on the target device and that expand on sketches by introducing user interface (UI) details and increased visual fidelity. These prototypes can be used to pitch ideas to clients, document interactions and even test usability. In this article, I will teach you how to use the iPad app Blueprint to put together such prototypes in the form of concept demos, which help to manage a client’s expectations when you are aligning your visions of a product.
