With contributions from a wide range of international scholars, this handbook brings together research, theory, and practice from diverse perspectives on the impacts of communication, media, and digital technologies on our society with a particular emphasis on digital technologies and societal futures. The chapters address current discourses and debates on digital citizenship, information quality and news literacy, privacy and identity, as well as forward-looking discourses on emerging technologies (including artificial intelligence, virtual reality, and the metaverse) and their intersection with diversity, equity, and inclusion in areas such as health and well-being, work and play, or participation. In addition to its multidisciplinary focus, the handbook also brings together diverse methodological approaches, including both quantitative and qualitative perspectives, and policy analysis. This comprehensive, application-oriented, and futures-centered volume serves as an important reference for both scholarly and policy-driven interest in exploring ways to understand, evaluate, and shape current and future social challenges emerging in the digital world.
