Posters, Demos and Lightning Talks - Call for Participation

Posters and demos are an opportunity to present late-breaking result, prototypes not yet validated through user studies, research in early phases, and other research best presented in this open format. They are an excellent opportunity to discuss and reflect your work with the conference attendees. Posters and demos will be displayed at a dedicated session in the conference when poster and demo authors will be available to discuss and demonstrate their work.

Posters depict research, experiences, methods, or conceptual prototypes that can trigger reflection and discussion among conference attendees. A poster submission might be based on work-in-progress, a small chunk of completed work, or synthesis of previously published work. We also highly encourage design fictions, creative pieces, think pieces, provocations, and other outside-the-box short works to be presented as posters.

Demos can be platforms, hands-on methods, or devices which allow participants to reflect and interact with them. Submissions can be about - but are not limited to - digital platforms that support collective action; hands-on methods aimed to design for collaboration that can be tried out at the conference; or interactive installations/artefacts that emphasize collaboration or collective making. Demos can be static or itinerant. Interactions can be visual, tactile, sound-based.

Lightning Talks consist of a 3 minutes talk or “elevator speech” in a session at the conference followed by a networking opportunity with peers and colleagues in the same session. This is an additional opportunity for presenting authors, especially students and other junior colleagues to stimulate discussion and debate, to introduce provocative ideas, concepts, approaches or to present late breaking results.

Conference topics for posters, demos and lightning talks (but not restricted to):

  • Theoretical, methodological, and/or conceptual contributions about key concepts relevant to CSCW and HCI, including critiqu.
  • Social, behavioral, and computational studies of collaboration and communication.
  • Technical architectures supporting collaboration.

Posters, Demos and Lightning Talks Submission Information
Submissions should include an extended abstract no longer than 4 pages including figures (references do not count against the page-limit), in the single-column ACM Master Article Submission Template (the past editions landscape format is now deprecated. For reasons why, please check:

Authors can use the following links to find the template file that fit their prefered environment:

In addition, demo authors should submit the requirements in a separate text (.doc) document. Please think of the following questions and any other relevant ones:

  • What do you need to run your demo?
  • What are the technical requirements?
  • What are the space/logistic requirements?
If your demo does not need any specific requirements, please let us know with the submission form.

The extended abstract should include author names and affiliations - these are not anonymous submissions. Upon acceptance, posters and demos authors will be asked to submit a Tabloid (A3 or 11 x 17 inches) sized placard to be displayed at the conference.Authors of accepted posters and demos have the choice to have their extended abstract published as part of the conference companion which will be available in the ACM Digital Library.

The final poster for display at the conference will be printed out by the participant in advance (standard A0, size 48 inches by 36 inches).

GROUP 2022 is using the Precision Conference System 2.0:

To submit, make a new submission to Society: "Group" > Conference/Journal: "Group 22" > Track: "Group 2022 Posters and Demos". Authors submitting papers for peer-review to ACM publications must comply with the SIGCHI Submission and Review Policy.

Posters, Demos and Lightning Talks selection process:
Contributions will be selected through single-blind peer review. Our review process will emphasize feasibility, quality, originality, and the capability to generate discussion (posters, lightning talks) and bring people together in a collective action (demos). We encourage submissions which will allow people to engage with the posters, demos and lightning talks during the conference in a collective manner.
