This chapter discusses and reflects on an ideation methodology that can help imagine future mobile only visualizations through a human-centered design approach. The chapter starts by outlining the general approach of the methodology. Ideation activities of three different design groups are then described to illustrate how one can adapt and adjust the methodology to specific ideation scenarios; and four different ideation activity approaches are presented with example results. The chapter ends with a reflection on the methodology itself and how the flexibility of the methodology can encourage a wide range of ideas to emerge.
