With several ideas for potential solutions on the table, we now need to find a way to evaluate them. For this, we use different kinds of prototypes for different purposes along our way: Low-resolution allow a quick depiction of an idea while high-resolution prototypes provide a realistic impression of functionality and appearance.
Nevertheless, irrespective of the resolution, prototyping is all about communicating. Each prototype makes ideas visible and tangible – and thus paves the ground for testing our ideas with users.
