To touch, experience and be present with a technology often tells us more than reading an article, or watching a presentation. Demos are one of the most exciting parts of ACM TVX as you can showcase your work to academics, industry and the wider community.

This year, demos are different. Though they will still be a part of the conference, and published in the adjunct proceedings, they will take place in the “Conference Bazaar”; a hands-on day of interactivity at the BBC.  This means that demos will be bigger, better and more extravagant than ever before.

Exhibiting your demo at TVX will allow academics and industry professionals to showcase their work, gain insightful feedback and for all conference delegates to get hands-on with the latest technological developments in the field. As in previous years, demos are intended to provide a forum for the informal presentation of interactive TV systems, VR broadcasting, media applications, prototypes, or proof-of-concepts. TVX demos are an excellent way to expose work and meet new people interested in you and your institution’s latest developments. Submissions are encouraged in all areas related to emerging media, interactive TV experiences, VR/AR experiences, as advertised in the conference call for papers.

Demo submissions take the form of 4-page papers (not including references) written in the Old SIGCHI Extended Abstracts Format. This must describe the research and what will be shown during the demonstration; all submissions will be peer-reviewed and selection will be based on the novelty of the research and interestingness of the demonstration.  

Demo submissions do not need to be anonymised. Please ensure that your submission answers the following questions:

  • What is the scientific or engineering concept behind the work?
  • What is the novelty of the work and how is the work different from existing systems or techniques?
  • What will be actually shown during the demo?

For the past couple of years we have encouraged authors to provide a video alongside their paper submission. This has proven invaluable – the video not only helps to support the submission, but will also be included in the digital version of the adjunct proceedings, and thus act as a lasting record of what was shown at the conference. The following video demonstrates what a submission video could look like, and gives some practical information on how to create one: instruction video on Vimeo.

After acceptance, the details the technical requirements of the demo should be provided. Please fill in these details in the Demo Rider document and send it to the demo chairs.

If you require any support in the preparation of your contribution due to accessibility reasons, please get in touch with our Inclusion and Accessibility Chairs (


Your submissions will be reviewed by chairs based on impact, and the quality of work. The review process will strive to recognize the potential of the submitted work for its future scientific, societal, economical or industrial impact.


Once accepted, demonstrators will be provided with a table, poster board, power outlet and wireless (shared) Internet. Demo presenters are expected to bring with themselves everything else needed for their demo, such as hardware, laptops, sensors, PCs, etc. However if you have special requests such as a larger space, special lighting conditions, additional networks, large displays and so on, we will do our best to arrange them, or to provide you with suitable rental services for free. At least one author must register to attend the conference to give the demo presentation.


Demos will be published in the conference proceedings (FigShare), not indexed in the ACM Digital Library.
