Call for Demos & Interactivity Prototypes

The MobileHCI 2021 Demo & Interactivity track provides a space for researchers and practitioners to bring hands-on experiences to conference attendees. We look forward to seeing and trying interesting:

  • Functional prototypes of devices and systems
  • Mobile and wearable applications and services
  • New interaction techniques
  • Innovative examples of mobile experiences
  • Toolkits and prototyping techniques for mobile and wearable interfaces

Important Dates

Submission of Poster and Demo papers May 21st, 2021 at 23:59 PDT (Friday)
Notification Jun 18, 2021 (Friday)
Camera-ready submission Jun 30, 2021 (Wednesday)

We welcome demonstrations & interactivity prototypes from students and researchers in all stages of their career. We particularly encourage undergraduate students and authors of accepted papers (details in the submission section) to contribute their demos. An appealing and innovative demonstration presents an opportunity to further display and disseminate your research and to attract the participation of attendees. Note that the demonstrations must be about research, not business. The demo forum is not an opportunity for marketing or sales presentations. Business-related visibility is only available for sponsors.


Submission Platform

  • All materials must be submitted electronically to PCS by the submission deadline.
  • In PCS, first click “Submissions” at the top of the page, from the dropdown menus select “SIGCHI”, “MobileHCI 2021” and “the track you want to submit to.

Submission Format

Preparing the Submission

The submission should include:

  1. Description: maximum of six-page description (including figures) of the demonstrated system, using the SIGCHI Extended Abstracts Format, max 4 MB. References do not count against paper length. If the system has been demonstrated before, describe if there are any changes to the proposed demo.
  2. Practical details (1-2 pages), including:
    • Contact information of the presenters.
    • Description of the resources that you will bring.
    • Specification of the general setup (tables, chairs, power), including any specific requirements (connectivity, lighting, sound, extra space etc.)
  3. Video: a brief video (2 minutes maximum) showcasing your demo.

Submission for authors of accepted papers

Accepted papers that include interactive experiences are granted a place in the demo session by default. We highly encourage all authors of demo-able papers to make use of this opportunity to showcase their work and connect with the attendees. For full paper authors, we provide a more light-weight demo submission process: to indicate that the accepted paper will be accompanied by a demo, authors only need to submit the practical details document, the specification of the infrastructure requirements. In addition, we ask authors to indicate the submission number of the paper accompanied by the demo. In case authors would like to have an additional extended abstract published, they can also decide to submit an up to six-page description in extended abstract format. Self-plagiarism must naturally be avoided.


Submissions do not need to be anonymous.

Selection process

The selection process for MobileHCI demos is curated, that is, selected by an esteemed committee, but not sent out to external reviewers. The curated demo content will be selected from demonstration submissions, accepted papers, as well as projects invited by the Demo & Interactivity chairs. Authors will not receive formal feedback on their submission other than the selection decision. Confidentiality of submissions will be maintained during the selection process. All rejected submissions will be kept confidential in perpetuity. All submitted materials for accepted submissions will be kept confidential until the start of the conference.


Accepted submissions will be included in the ACM Digital Library as part of the MobileHCI 2021 Adjunct Proceedings. ACM will send you a copyright form, which you have to complete. Once completed, ACM will provide you the copyright information to be put into your paper. You can then submit the camera-ready version (including the copyright notice) through the submission system.

Presentation Format

Upon acceptance, you have to present your demo at the conference. At least one author of a demo must register by the early registration deadline. Participants are expected to bring the necessary equipment to the conference site with them. By default, the conference will provide:

  • One table
  • One poster board
  • One power outlet
  • Wireless internet connectivity. If your demo heavily relies on Wi-Fi connectivity, we recommend you to bring your own Wi-Fi router. The chairs will do their best to accommodate requests for additional setup requirements. Please ask ahead of time!
