Message from the Demonstrations Chairs

2018 represents the 50th anniversary of Douglas Engelbart’s “Mother of all Demos” in 1968, and we are not going to let this occasion pass unnoticed. We celebrate the anniversary by renaming the Interactivity track to “Demonstrations”, and by focusing the track onto a one-evening celebration at the Monday reception. This means for one night, Demonstrations are front and center at the conference: a high-visibility, high-impact forum of the Technical Program that allows you to present your hands-on prototypes and share novel interactive technologies with the entire audience. The Demonstrations  track promotes and provokes discussion of novel interactive technologies, and invites contributions from research, industry, startups, maker communities, the arts, and design communities. We encourage submissions from any area of human-computer interaction, games, entertainment, or design. Sharing hands-on experiences is often the best way to communicate your work: If you have an interesting prototype, device, system, exhibit or installation, we want to know about it!

Preparing and Submitting your Demonstrations Submission

Deadline: 25 January 2018: Extended Abstract, Video, Still Image, and Supplement

This year we will use one single late deadline of 25th of January 2018 to allow you to submit your most cutting-edge work. You will be required to submit an Extended Abstract detailing the work, a picture depicting the work, a video, and a supplementary document detailing the requirements for the exhibit. All submissions should be fully publication-ready at the moment of submission (i.e., not anonymized). The organizers will provide you with a standard table, WiFi, electrical outlets, and space for a poster. Additionally, presenters can request dimmed lighting conditions, a 24” LCD display, a 50” LCD Display, and speakers. Projectors and other equipment will need to be brought in or rented. Due to the expected crowd on Monday evening, we ask that your supplement includes a plan for dealing with line-ups. We ask that you detail how you are going to limit your presentation time to a maximum of 5 minutes per person by providing the “elevator pitch” in the supplement file (see below). This is especially important for wearables and AR/VR demonstrations.

Previously-published work will be accepted into the Demonstrations track, on the condition that the publication and presentation history is clearly outlined in the submission, and that the submission is novel in that it was not demonstrated before at a scientific conference. The Demonstrations track encourages authors of submitted CHI Papers to submit an extended abstract for Demonstrations, although there is no formal association between demonstrations and accepted papers.

Submissions must have the following components:

1. Extended Abstract

The extended abstract is a 4-page short paper in the Extended Abstracts Format, including references. 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 CHI conference community, as well as to the broader CHI community, emphasizing its novelty, uniqueness, and rationale.

2. Video

A video is a good way to communicate demonstrations to the reviewers and provides an archive of the work. You must submit a video in addition to your written documentation. The video must be no longer than 5 minutes and all uploaded content (PDF(s) + image + video) must be less than 100 MB. Please make sure that your video is playable on standard PC and Macintosh computers. We recommend that you encode your video as an MP4 using the H.264 codec. Submitted videos will be used for review purposes. The videos may also be displayed at the Demonstrations site and possibly on web sites previewing CHI content. Be sure to have permission for all content, and use rights-free music tracks.

3. Still Image

You are required to upload a still image of at least 1500 x 1200 px that represents your work. The image is required for publications and conference publicity.

4. Supplement

A supplement is mandatory for all Demonstrations 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 organise Demonstrations. Abstracts that do not provide a complete supplement using the template will not be accepted. 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 (etc.) requirements for the demonstration, exhibit, or installation, and to evaluate whether the authors have a plan on accommodating queues of viewers. The supplement should be no longer than 4 pages. Like all other materials, the supplement must be submitted through the PCS submission system and the total of PDF(s), still image, video, and supplement cannot exceed 100 MB.

Demonstrations Selection Process

Demonstrations will be curated and may include work that was invited or selected from other submissions. The selection process includes reviews by the Demonstrations program committee, and will take into account feasibility, available space at the conference, and other relevant information. Our intention is to ensure that the Demonstrations track is exciting, while representing a range of projects being undertaken across diverse CHI and related communities.

Submissions should not contain sensitive, private, or proprietary information that cannot be disclosed at publication time. Submissions should NOT be anonymous. However, confidentiality of submissions will be maintained during the selection process. All rejected submissions will be kept confidential in perpetuity.

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date may affect the deadline for any patent filings related to published work. (For those rare conferences whose proceedings are published in the ACM Digital Library after the conference is over, the official publication date remains the first day of the conference.)

Before the Conference

At the time of the final submission, authors will be asked to submit a 30-second video preview summarizing the paper. This is optional, but highly encouraged, as it will increase the visibility of publications before, at the conference, and in the ACM digital library in perpetuity. The deadline for submitting 30-second video previews  is March 3, 2018 (12pm (noon) PST / 3pm EST), so authors have additional time to work on them after the camera-ready deadline. Video previews count towards the total submission size of 100MB, so we recommend that the camera-ready submission does not exceed 80MB.

At the Conference

If accepted to Demonstrations, you will be assigned a space in the Demonstrations space. Support for building on-site and moving in/out of large/heavy exhibits is only provided before the conference start and after the conference. At CHI Demonstrations, you will have a space for your work, but you are responsible for bringing and setting up most of any other equipment that is required for presenting your work.

For accepted exhibits, we can provide help with plasma displays, etc. only when these are absolutely required to enable the demonstration. Please note that Demonstrations can only request limited equipment and that projectors must be brought or rented locally by the authors. Please provide all details using the supplement PDF. Note that although student volunteers will be present in the Demonstrations space at all times, CHI will not be able to provide anyone to run your demonstration.

After the Conference

Accepted Demonstrations Extended Abstracts and Videos are not considered “Archival Publications” but will be distributed in the CHI Conference Extended Abstracts and placed in the ACM Digital Library. Those Extended Abstracts that are associated to accepted CHI Papers will link to the associated archival publication.
