Welcome to this issue of the Proceedings of the ACM on Human-Computer Interaction, which brings together contributions from the Mobile Human-Computer Interaction (MHCI) community. This issue showcases innovations in research focused on mobile, wearable, and personal devices. Research in MHCI encompasses both technical innovations and social considerations. Mobile technologies accompany us throughout our daily lives: at home, at work, in traffic, and out in the wild. However, while mobile technologies provide the capacity for constant connectivity, they also pose risks of harm and unintended consequences. There has never been a more pressing time to debate and explore the meaning of digital culture, and to understand how mobile technologies can and should be used to connect us, our data, and mobile applications and services in meaningful ways - true to the conference theme of 'Connecting Cultures'.
