Call for Posters and Demos

ACM HotMobile’27 continues the series of highly selective, interactive workshops focused on mobile applications, systems, and environments, as well as their underlying state-of-the-art technologies. HotMobile’s small workshop format makes it ideal for presenting and discussing new directions or controversial approaches. HotMobile seeks proposals for posters and live demonstrations describing novel work on mobile systems, applications, and services. Posters and demonstrations will be presented during a reception at the workshop.

The poster/demo session is meant to introduce new or ongoing work and provide opportunities for authors to interact directly with workshop attendees. Posters are well suited to controversial work that can generate discussion or promising new ideas that have not been thoroughly evaluated. Live demos provide an opportunity to demonstrate the feasibility and usefulness of your research.

This year’s poster/demo session will feature a Best Poster/Demo award.

Important Dates

  • Submission Deadline: January 11, 2027 AoE
  • Notification of Acceptance: January 15, 2027
  • Camera Ready Deadline: January 20, 2027 AoE

Submission Guidelines

Submissions must include an extended abstract no longer than one 8.5x11-inch page, including all figures and references. The poster/demo should be uploaded to: https://hotmobile27-posterdemo.hotcrp.com/.

Please note the distinction between the poster submission and the presentation poster. The initial submission is a one-page text description subject to rigorous peer review. Upon acceptance, authors are required to design, print, and bring their own physical posters to the venue. Detailed size and formatting specifications will be announced soon.

More Details on the Submission Process

Please set up your page to be US letter size, 8.5x11 inches, two columns, using 10-pt font size for the text body, with at least one-inch margin on all sides. Submissions must be in Adobe PDF format. Please include the title of the poster/demo and the author list, including affiliations in the PDF file. Prefix your title with “Poster:” for a poster submission and “Demo:” for a demo submission. Please do not anonymize your submissions.

For demo submissions, we encourage the submission of an optional companion video that illustrates the demo. The companion video should highlight the technical contributions of the demo and should be no more than one minute in length. Include the YouTube URL of the companion video in the extended abstract.

Call for Papers

The 28th Annual International Workshop on Mobile Computing Systems and Applications
(ACM HotMobile 2027)

Sponsored by ACM SIGMOBILE
Tucson, AZ, USA

Submission site: https://hotmobile27.hotcrp.com/

ACM HotMobile 2027, the Twenty-eighth International Workshop on Mobile Computing Systems and Applications continues the series of highly selective, interactive workshops focused on mobile applications, systems, and environments, as well as their underlying state-of-the-art technologies. HotMobile's small workshop format makes it ideal for presenting and discussing new directions or controversial approaches.

We solicit submissions of papers that (1) focus primarily on systems and applications and (2) propose new directions of research, advocate non-traditional approaches to old (or new) ideas, or generate controversy and discussion. We especially encourage papers that identify fundamental open questions, advocate a new approach, offer a constructive critique of the state-of-the-art, debunk existing assumptions, report unexpected early results, report on promising but unproven ideas, or propose new evaluation methods. Novel ideas need not be supported by full evaluations; well-reasoned arguments or preliminary evaluations suffice. The program committee will explicitly favor early work and papers likely to stimulate reflection and discussion over a “6-pages conference paper.”

We take a broad view of Mobile Systems research. This includes:

  • Novel applications, environments, and devices supporting mobility.
  • Operating system and distributed system support for mobile computing.
  • Wearable computing, internet of things, edge computing, sensing, and context-awareness.
  • HCI issues related to mobile computing.
  • Security and privacy of mobile computing.
  • Management, configuration, and deployment of systems supporting mobility.
  • Wireless technology, as it pertains to mobile systems and applications.
  • Social issues related to mobile computing.
  • System and application support for the use of ML, foundation models, and agents on mobile platforms.
  • Improving efficiency of mobile platforms, including durability, energy considerations, and e-waste considerations.

Important dates:

  • Deadline for submissions: Friday October 9th, 2026, 11:59pm AoE
  • Acceptance notification: December 16th, 2026

Presenting at HotMobile is a good way to get early feedback on research ideas at least one year away from a full-fledged conference submission to ACM MobiSys or other high-quality conferences. A full-length paper on the same topic submitted to a conference in less than a year is unlikely to include sufficient new material and mature ideas to warrant publication.

As is customary, papers must not have been published elsewhere and may not be simultaneously under submission at another venue. Papers accompanied by nondisclosure agreement forms are not acceptable and will be returned to the author(s) unread. As customary with the scientific peer review process, submissions will be handled as confidential material during the review.

Submissions should contain 6 or fewer U.S. letter pages in PDF format, including all references, figures and tables. The submissions should not be anonymous. The submissions must meet the following formatting requirements:

  • Font size no smaller than 10pt.
  • Font size of the bibliography no smaller than 9pt.
  • Double column format with each column having dimensions 9.25 inches x 3.33 inches, a space of 0.33 inches between the two columns, and with no more than 55 lines of text per column.
  • Fit properly on US letter-sized paper (8.5 inches x 11 inches).

We recommend the use of the "sigconf" ACM proceedings template, available at: http://www.acm.org/, with the font size of the main body amended to 10pt. An example Tex document can be found here. For more submission guidelines, please visit the conference website. Please note that it is the responsibility of the authors to ensure that the submissions are meeting all formatting requirements.

The papers accepted to HotMobile 2027 will be publicly available from the workshop's website for a limited time window, as per ACM's Digital Library's Policy.

Important update on ACMs open access publishing model for 2027 ACM Conferences!

All ACM publications, including those from ACM-sponsored conferences, are 100% Open Access. Authors have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With ~3,000 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 76%).

Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial or discretionary waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the APC Waivers and Discounts Policy. Please keep in mind that waivers are rare and are granted based on specific criteria set by ACM.

To support authors and institutions as they continue to adapt to ACM’s Open Access publishing model, the ACM Council has approved subsidized APC rates for calendar year 2027 allowing more time for institutions to join ACM Open. The subsidy will offer:

  • $500 APC for ACM/SIG members
  • $750 for non-members

This represents a 29% discount off current APC list pricing, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period.

This temporary subsidized pricing will apply to all conferences scheduled for 2027.
