Have a gaze interaction technique to share? Want to show off how your new eye tracking method works? Or want to discuss your study setup with other eye tracking researchers? At ETRA 2021, we will have a Demo & Video session, during which researchers give demonstrations of their research or show videos of their work. We encourage new and exciting ideas that may not yet be fully tested. To take part in this session, we request an extended abstract (4 pages + 1 additional page for references) to be submitted.

If submitting a video presentation, a video with audio is required. For demos, we also require that a video with audio is submitted for review. See below on how to submit.

To submit to the Demo & Video Track, you need to prepare

• an extended abstract (4 pages + 1 additional page for references), and
• a video submission.

Note: for demos we also require a video showing the demonstration. This video will be used for reviewing purposes. Only submissions of type video will be played at the conference. However, demo submissions might be accepted as a video in case they lack demonstrability.

Detailed instructions are available below.

The extended abstract will be part of the ETRA 2021 proceedings. Copyright of the work will be held by the authors.

Different to last year, we require that authors of submitted long and short papers submit a separate extended abstract (4 pages + 1 additional page for references).

A good extended abstract should:

1. Fall under the topics mentioned for the ETRA 2021 conference.
2. Motivate the use cases of the work.
3. Describe the novelty of the tool/method and how it relates to other work.
4. Describe any inner workings of the tool/method as necessary.
5. Describe experiences gained in developing the tool/method.

Submissions to the Demo & Video Track will be juried by the Demo & Video chairs. We follow the CHI Selection Process of juried content (https://chi2021.acm.org/for-authors/selection-processes), which means a less rigorous process and light feedback.

Abstracts should be 4 pages + 1 additional page for references in length and should follow preparation instructions found at: http://www.siggraph.org/learn/instructions-authors. To prepare the content of the PDF file, SIGGRAPH encourages authors to use LaTeX.

When generating the PDF file, please make sure that the fonts are embedded in the PDF file. This will ensure that reviewers can view the paper without problems. The title of the paper should be preceded by “Video” or “Demo” to highlight the type of paper. The submitted abstracts should not be anonymized for peer review. In addition to the extended abstract, you will be asked to submit a video.

The video should depict your technology in action and we encourage researchers to explain in the video a) the motivation for their work, b) the specific problem being addressed, and c) the demonstrated solution to the problem. Note that the video should be self-explaining, no in-person explanation of the videos should be necessary at the conference. We highly encourage videos to either include an audio track and discourage the use of background audio or music. If you feel uncomfortable recording your own voice, check the web for a text-to-speech tool to generate your audio commentary. The video should include a title slide with the title of the work, authors, affiliations, etc. at the start of the video. A submitted video should have a maximum length of 5 minutes and should not be larger than 100 MB. We recommend using MP4 format with H.264 codec and a resolution of 1280 x 720 px, at 24 to 30 frames/s. Most video production systems can encode in this format and most video applications are able to play it. If you use a different codec, you risk that reviewers might not be able to view the video clip and you will need to re-encode the video clip for the conference proceeding USB. The video should play in the VLC media player version 3.0 (freely available at https://www.videolan.org/vlc) without additional software, codecs or settings.
