Call for Participation

AfriCHI 2021 welcomes the submission of posters and demos. Posters and demos present a valuable opportunity for longer, in-depth face-to-face discussions of the work, in a way that may not be possible with papers. We welcome posters and demos submissions where the work and authors will benefit from this interaction, such as those reporting late-breaking and cutting edge work, emergent new technologies, preliminary and on-going work, in any of the conference themes.


Poster submissions allow for the presentation of work in progress, where a level of maturity that makes it valuable to present to the AfriCHI community has been reached. Whilst the broader work may not be completed, the contents of the poster submission should still make a clear contribution to broader HCI knowledge, whether realized or while under development with promising initial steps.


Demonstrations are self-contained exhibits with logistically simple requirements. Demo submission invites interactive art and design installations, interface or system demonstrations, tangible prototypes and other interactive experiences that critically or creatively explore the conference themes and provoke discussions around novel technologies.

Submission Format

Submissions must have the following components:

Extended abstract

The extended abstract is a 4-to-6 page description (including references) in the Extended Abstracts Format. This requirement is for both posters and demos submissions.


It should be self-contained and clearly describe the novelty and distinguishing ideas of your work, even for readers who are not able to view the related poster or demo at the conference. It should also include a brief description of related research and a clear description of the work along with future work plans.


It should be self-contained and clearly describe the novelty and distinguishing ideas of your project, even for readers who are not able to view the related demonstration at the conference or associated videos. Your abstract should include:

  • A description of the system, installation or exhibit and the problem it addresses. Where relevant, discuss the broader context and questions that your work promotes reflection upon.
  • A description of the relevance of the work to the immediate conference community, as well as to the broader HCI community, emphasizing its novelty, uniqueness, and rationale.
Additional elements

Additionally, all authors are also required to submit an image and strongly encouraged to submit a video about their poster or demo. Demo authors are also required to submit a requirements supplement describing the technical set-up and space requirements for their demos.


Authors should also upload the poster or a schematic description of the demo as a still image with at least 1500 x 1200 px.


The video should summarize the content of the extended abstract. Submitting a video is optional, but highly encouraged, as it will increase the visibility of your demonstration before, at the conference, and in the ACM digital library in perpetuity. Please make sure that your video is playable on standard PC and Macintosh video players. We recommend that you encode your video as an MP4 using the H.264 codec. Be sure to have permission for all content, and use rights-free music tracks.

Requirements supplement

A requirements supplement is mandatory for demos submissions and describes technical set-up and space requirements. This supplement is useful for describing anything that does not fit or is not appropriate for the extended abstract and is used to determine how to organize demonstrations. Supplement materials are for the purpose of review and planning only and will not be published. This information is used to determine spatial, technical, lighting, power requirements, etc. The supplement should be no longer than 4 pages. All materials (extended abstract, image, eventual video, eventual requirements supplement) must be submitted through the submission system and the total size of the submission cannot exceed 100 MB. Submissions should not contain sensitive, private, or proprietary information that cannot be disclosed at publication time. Submissions should NOT be anonymous. However, the confidentiality of submissions will be maintained during the selection process. All rejected submissions will be kept confidential in perpetuity.

Selection process 

To ensure that we get as late-breaking work as possible, posters and demos constitute a highly selective juried track, so authors should not expect in-depth reviews. The demo selection process will take into account feasibility, available space at the conference, and other relevant information. Our intention is to ensure that the track is exciting while representing a range of projects being undertaken across diverse HCI and related communities. Authors of accepted submissions will receive instructions on how to prepare and submit the publication-ready version, and details on the demonstrations and installations presentation and scheduling at the conference.

Technical setup at the conference

Accepted posters & demos will be presented during the conference in the posters & demo area. The organizers will provide a poster stand able to hold an A1-sized poster in any orientation. For the demonstrations, the organizers will provide a standard table, WiFi, and electrical outlets. Additionally, presenters can request a screen and speakers. Demonstrations setup and removal by the end of the conference is handled by the authors. We aim to have the posters and demos visible on all days of the conference.  Poster and demo authors are expected to be present at their posters during dedicated poster sessions. Poster presenters need to print posters themselves, as well as attach it to the poster wall as instructed before the conference.


Extended abstracts will appear in the Proceedings of AfriCHI 2021, which will be published in the ACM Digital Library. Images will be published as source material in the ACM Digital Library. Authors of accepted posters must present at the AfriCHI 2021 Conference, and register for the conference.
