The HCII2020 Design Café provides a venue for the discussion and rethinking of important HCI topics in the domain of "Human-Environment Interactions". Inspired by the World Café method, the HCII2020 Design Café aims to provide a small-group forum for productive, critical discussions in a moderated face-to-face group situation and to identify innovative approaches for transfering ideas into practice.

The topics to be discussed are informed by the findings of the article “Seven HCI Grand Challenges”, which arise in the current and emerging landscape of rapid technological evolution towards more intelligent interactive technologies, coupled with increased and widened societal needs, as well as individual and collective expectations that HCI, as a discipline, is called upon to address. The article presents the results of the collective effort of a group of 32 experts involved in the community of the Human Computer Interaction International (HCII) Conference series. In particular, the HCII2020 Design Café will specifically address the Grand Challenge of Human-Environment Interactions. The findings and results of the HCII2020 Design Café will be published.
