Abstract :
More and more, people communicate via not one, but many messaging apps and social media platforms. In particular, couples, close friends and families use multiple apps to express caring in diverse ways throughout the day. I argue that we need a deeper understanding of how people communicate via ecosystems of communication apps. In this thesis, I show that the way people communicate in an app is not only influenced by its contacts and functionality but also by the contacts and functionality in their other apps. I also show how app-exclusive features prevent people from expressing themselves consistently across their apps. Moreover, I present novel designs, technologies and studies that explore how to better support ecosystems of communication apps by repurposing three mechanisms currently available in mobile operating systems: notifications, which users can overlay on top of any open app; gesture commands, which users could perform on any app that recognizes gestures; and soft keyboards, which appear in any app where users can type text.

MICRO VISUALIZATIONS: DESIGN AND ANALYSIS OF VISUALIZATIONS FOR SMALL DISPLAY SPACES
The topic of this habilitation is the study of very small data visualizations, micro visualizations, in display contexts that can only dedicate minimal rendering space for data representations. For several years, together with my collaborators, I have been studying human perception, interaction, and analysis with micro visualizations in multiple contexts. In this document I bring together three of my research streams related to micro visualizations: data glyphs, where my joint research focused on studying the perception of small-multiple micro visualizations, word-scale visualizations, where my joint research focused on small visualizations embedded in text-documents, and small mobile data visualizations for smartwatches or fitness trackers. I consider these types of small visualizations together under the umbrella term ``micro visualizations.'' Micro visualizations are useful in multiple visualization contexts and I have been working towards a better understanding of the complexities involved in designing and using micro visualizations. Here, I define the term micro visualization, summarize my own and other past research and design guidelines and outline several design spaces for different types of micro visualizations based on some of the work I was involved in since my PhD.
