Interaction design & prototyping
We can help you with the interaction design of a brand new product, or with improving the interaction on an existing product. (Interaction design is the design of how the user interface works, rather than just how it looks.)
The output is a clickable prototype (we like using Axure to make these). Prototypes help all stakeholders to agree on what they want from the interface, they can easily be usability-tested, and developers love using them as a base from which to build, in conjunction with a BRS.
