Editorial Introduction - GROUP 2022 Second Wave

For over a quarter century, GROUP has offered a premier yet intimate and welcoming venue for agenda-setting, diverse research. Although the traditional focus of the conference is on supporting group work, it has expanded to include research from computer-supported cooperative work, sociotechnical studies, practice-centered computing, human-computer interaction, computersupported collaborative learning, participatory technology design, and other related areas. The work presented in this issue embodies that interdisciplinary ethos. Papers in this issue cover a wide range topics, from human-AI collaboration, to collaboration in virtual reality, to perceptions of privacy and security, to the myriad impacts of the COVID-19 pandemic. The application domains are similarly wide ranging, from health data, to civic engagement, to educational settings, to government provision of social services. Similar to the 2021 issue, this issue also continues the tradition of design fiction at GROUP. This issue of PACM:HCI brings you papers from the planned 2022 ACMConference on Supporting Group Work (GROUP 2022). Typically, the GROUP conference occurs every two years. However, research developments do not necessarily follow conference deadline cycles. Thus, the GROUP conference offers authors the opportunity to submit to multiple waves. The first wave of papers for this conference were published in July 2021 in Volume 5 of PACM:HCI, and papers from this current issue were first submitted in May 2021. Both of these sets of papers published as part of the planned GROUP 2022 conference were authored and reviewed during the COVID-19 pandemic. These papers represent commendable volumes of hard work and resilience, not just from the authors, but also from the reviewers, the program committee, and the conference organizers. Additionally, the pandemic forced a major change to the conference at which these papers will be presented.
