State of Prototyping Mobile Application User-Interfaces

Abstract

This chapter gives an introduction into the scientific discussion and practices of prototyping mobile application user interfaces. For this, it first takes a more general perspective on prototyping (Sect. 2.1), where the term prototyping is defined, its goals are displayed, and different prototyping paradigms are explained. Followed by that, in Sect. 2.2, a particularly relevant approach for this work is displayed in more detail: the approach of a paper-based prototyping. After that, in Sect. 2.3, the text concentrates on prototyping techniques for mobile app user interfaces. Here, especially mixed-fidelity prototypes and their development in different approaches are discussed, and an existing gap in the technological concepts and tools is identified. This motivates the research questions that build the objectives of my work, which are postulated in the Sect. 2.4 that concludes this chapter.
