This book was first published in Swedish in 1998 (Design av informationsteknik, Studentlitteratur, Lund). It is an attempt to explore the consequences of looking at the design of digital technology as a design discipline, related to fields such as architecture or industrial design. Erik and I introduce a set of concepts that can be used for thinking about the design process, the designer’s skills and ways of extending them, design methods and techniques, and digital products and their use qualities.

It's now available as an ebook on the MIT press portal http://mitpress-ebooks.mit.edu/product/thoughtful-interaction-design
