Workshop: Fostering Historical Research in CSCW&HCI (CSCW'19, Austin, TX, USA) This day-long workshop aims to support and grow the community of CSCW and HCI scholars that investigate the past to inform the design, critique and conceptualization of technology. At this workshop, we will learn from examples of historically-based CSCW and HCI work, explore issues in historical method that come up in such work, share methods and techniques, provide feedback and support to ongoing investigations; and define a shared agenda for future research on this topic. The workshop will also highlight research and methods that focus on non-Western contexts and that give voice to historically marginalized groups. Based on the workshop, we will develop a white paper and a website that will collect resources to support CSCW based historical investigations. To apply, please send a 4-page position paper to cscwhistory@gmail.com by September 21st 2019. Position papers should be the ACM Extended Abstract format and take one of the following forms: 1) description of an ongoing historical research project which seeks to make contributions to CSCW and/or HCI; 2) engagement with questions of how one or more historical methods can be carried out in our field, including discussion of validity and evaluation of historical research; 3) discussion of specific contributions that historical research can make to CSCW and HCI. The workshop will take place as part of the 22nd ACM Conference on Computer-Supported Cooperative Work and Social Computing in Austin, Texas during November 2019. More information about the conference is here: http://cscw.acm.org/2019/. At least one author of each accepted position paper will be required to register for the workshop and at least one day of the conference.
