The first annual ACM SIGCAS Conference on Computing and Sustainable Societies (COMPASS 2018) invites submissions of Full Papers and Notes for the conference to be hosted at Facebook (San Francisco, CA) from June 20th to June 22nd, 2018. ACM COMPASS is a re-creation of the ACM DEV conference, which was held annually between 2010 and 2016. The new conference expands the focus of the original conference to explicitly welcome work on underrepresented communities worldwide and to include work on sustainability. To ensure strong technical contributions, the conference will accept papers and notes based on tracks corresponding to the computing areas they draw upon. The tracks for the 2018 conference are Systems, Human-Computer Interaction (HCI), Data Science, and Applications.
