An important public discussion is underway on the values and ethics of digital technologies as designers work to prevent misinformation campaigns, online harassment, exclusionary tools, and biased algorithms. Values and Ethics in Human-Computer Interaction reviews 30 years of research on theories and methods for surfacing values and ethics in technology design. It maps the history of values research, beginning with critique of design from related disciplines and responses in human-computer interaction (HCI) research. The review then explores ongoing controversies in values-oriented design, including disagreements around terms, expressions and indicators of values and ethics, and whose values to consider. Next, it describes frameworks that attempt to move values-oriented design into everyday design settings. These frameworks suggest open challenges and opportunities for the next 30 years of values in HCI research.
