“Experience design, especially interface design, is perhaps one of the most fertile fields for the idea of scientific design. (…) In this article, we discuss three examples of solid scientific knowledge that are often applied to interface design. In our view, the translation of scientific findings into design practices is not always as straight-forward as we wish it would be. The concept of scientific knowledge refers to convictions about the world that have been reached through controlled processes of inquiry and investigation and that, in principle, are not influenced by arbitrary conventions, personal preferences, or individual interests. Scientific knowledge is derived from systematic observation that gradually leads to an understanding of reality that must be valid for everyone.”
