An important part of the Communities & Technologies 2021 program is the live demonstrations and posters. This track allows researchers, practitioners, and professionals to share their research or work-in-progress, and demonstrate early implementations or prototypes, which are related to the main topics presented in the call for participation. All accepted submissions are showcased during the conference, where the presenters can interact with the conference attendees to exchange ideas and get feedback.
