As interactive technologies evolve and reach into every aspect of modern life, research practices in human-computer interaction (HCI) have changed. The methodological and epistemological foundations of the field are shifting to reflect the diversity of contexts in which rapidly changing digital technology is being used. Alongside these changes, new ethical challenges emerge for the HCI community, both in terms of research ethics and responsible research and innovation. Open dilemmas include issues such as the shifting meaning of informed consent, anonymisation or privacy in an always-online world. The SIGCHI Ethics Committee has been established to look into the processes, practices and structures at SIGCHI venues to deal with such ethical dilemmas and how they can be addressed in a transparent, consistent and open way. This town hall style panel will be an opportunity to prompt community discussion and collect input into how we can further address these challenges.
