Prototyping and testing throughout all the design process as a methodology for developing interaction design projects

Abstract

Based on the experience of developing a mobile app, this paper discusses the prototyping and testing cycles not as final steps of a design process, but as a methodology to be used from the beginning to the end of a project. On the project described in this paper, prototyping was not a tool used only to test the final product, but it was present throughout the design process.
