Dear colleagues, We would like to draw your attention to the upcoming ECSCW conference in the summer. There are still opportunities to contribute by submitting a short contribution (2000 words max) to the Posters and Demos track until February 22. The European Conference on Computer-Supported Cooperative Work is an international venue on practice-centered computing and the design of cooperation technologies. It is a series of conferences on computer-supported cooperative work located in Europe that was established in 1989. The 19th edition of ECSCW will take place in Zurich, Switzerland, from 7th to 11th June 2021. The presentation of posters and demos is a key element of the ECSCW conference. For presenters as well as recipients, the poster & demo session provides a lively environment for getting in touch with late-breaking research, preliminary results, innovative ideas, and early-stage research and design explorations. At a special session during the conference, authors are given the opportunity to showcase their research to interested delegates, as well as to involve them in discussions about their work, exchanging ideas, providing feedback, and sharing work-in-progress relating to CSCW. Posters provide a great opportunity to present preliminary research results and disseminate novel ideas to conference visitors. Posters also offer the space to discuss potential collaborations and the emergent issues in CSCW in an informal manner with the larger ECSCW community. We particularly invite submissions that introduce speculative or provocative ideas that challenge existing epistemologies and methodologies. Demos may be submitted in various forms. These may be interactive research prototypes or products, but also low-fi prototypes, such as paper mock-ups etc. In addition, the demo session will provide space for exhibiting innovative materials that have been developed in the context of the deployment of (user-centered) research methods – for example, innovations in storyboards, personas, and other materials that foster creativity in the design process. How to apply? Both submission categories (posters and demos) require the submission of a short paper (2000 words maximum excl. references, figures, and a 150-word max. abstract) in the PDF format through the EasyChair platform<https://easychair.org/my/conference?conf=ecscw2021#>1#>. More details about the submission process (incl. templates) can be found at our website https://ecscw.eusset.eu/2021/posters-demos/ All accepted submissions will be published as short papers in the European Society for Embedded Technologies (EUSSET) digital library http://www.eusset.eu/digital-library Key dates Submission deadline: February, 22 2021, 23:59 AoE Notifications: March 31, 2021 Camera-ready submission: May 11, 2021 Conference: June 7-11, 2021 Attendance As of now, the conference is planned in Zurich, Switzerland from 7th until 11th of June 2021.
