Case Studies

The following case studies show you different aspects of interaction design, as carried out in practice – both in research and in industry. The first three are summarised in the book, but here we present a more detailed description. The other case studies are from previous editions of the book, and contain some broken links.

Each case study includes a downloadable PDF file, and a screen-readable version to be browsed online.
