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.
