ACM IUI 2021

This year's conference will be completely virtual using Whova. Find out more by clicking here

The original page lengths were based on the old 2-column format. We have switched to the new single column format and the page lengths are now 14 and 6 for long and short papers.

The paper format should be single column. Specific templates are listed lower on this page.

ACM IUI 2021 is the 26th annual premier international forum for reporting outstanding research and development on intelligent user interfaces.

ACM IUI is where the Human-Computer Interaction (HCI) and Artificial Intelligence (AI) communities meet, with contributions from related fields such as psychology, behavioral science, cognitive science, computer graphics, design, the arts, and more. Our focus is on improving the interaction between humans and digital technology, by leveraging both HCI approaches and state-of-the art AI techniques from machine learning, natural language processing, data mining, knowledge representation and reasoning.

Why you should submit to ACM IUI

While other conferences focus on either the AI or HCI side of this research, we address the complex interaction between the two. We strongly encourage submissions that simultaneously discuss research from both HCI and AI. We also welcome works that focus more on one side or the other, but still highlight the connections between the two. We value papers that contribute methodology or theory for the evaluation of intelligent user interfaces. We do not require evaluations with users, but we do expect papers to include an appropriate evaluation for their stated contributions.

ACM IUI welcomes contributions from all relevant arenas—academia, industry, government, and non-profit organizations—and gives its participants the opportunity to present and see cutting-edge IUI work in a focused and interactive setting. The conference is large enough to be diverse and lively, but small enough to allow for extensive interaction among attendees and easy attendance to the events that the conference offers, ranging from oral paper presentations, poster sessions, workshops, panels and a doctoral consortium for graduate students.


We invite original paper submissions that describe novel user interfaces, applications, interactive and intelligent technologies, empirical studies, or design techniques. We do not require evaluations with users, but we do expect papers to include an appropriate evaluation for their stated contribution.

Accepted papers will appear in the ACM Digital Library and citation indices. A selected set of accepted top quality full papers will be invited to submit their extended versions for publication in an ACM Transactions on Interactive Intelligent Systems (TiiS, special issue titled "Highlights of IUI 2021".


IUI topics of interest include, but are not limited to:

Application areas

  • Internet of Things (IoT)
  • Education and learning-related technologies
  • Health and intelligent health technologies
  • Assistive technologies
  • Social media and other Web technologies
  • Mobile applications
  • Artificial personal assistants
  • Information retrieval, search, and recommendation system

Interface types

  • Affective and aesthetic interfaces
  • Collaborative interfaces
  • Speech-based interfaces
  • AR/VR interfaces
  • Intelligent wearable and mobile interfaces
  • Ubiquitous smart environments


  • Agent based interfaces (e.g., embodied agents, virtual assistants)
  • Multi-modal interfaces (speech, gestures, eye gaze, face, physiological information, etc.)
  • Conversational interfaces
  • Tangible interfaces
  • Intelligent visualization

Methods and approaches

  • Methods for explanations (e.g., transparency, control, and trust)
  • Persuasive technologies in IUI
  • Privacy and security of IUI
  • Planning and plan recognition for IUI
  • Knowledge-based approaches to user interface design and generation
  • User Modelling for Intelligent Interfaces
  • User-Adaptive interaction and personalization
  • Crowd computing and human computation
  • Human-in-the loop machine learning

Evaluations of intelligent user interfaces

  • User experiments
  • User studies
  • Reproducibility (including benchmarks, datasets, and challenges)
  • Meta-analysis
  • Mixed-methods evaluations

Submission Guidelines

For accepted papers, at least one author must attend the conference virtually to present the work.

We accept two forms of paper contributions:

Full papers (anonymized 14 pages, references do not count toward the page limit) should make substantial, novel, relevant, and appropriately evaluated contributions to the field. Note that rejected full papers will not be considered for acceptance as short papers.

Short papers (anonymized 6 pages, references do not count toward the page limit) make a much more focused and succinct contribution to the field. Short papers are not expected to include a discussion of related work that is as broad and complete as that of Full papers. Short papers are not preliminary work; such work should be submitted to the Demos and Posters track. Short papers are expected to have an evaluation that is appropriate for the contribution.


ACM IUI uses a double-blind review process. All submissions must be appropriately anonymized according to the following guidelines:

  • 1. Author’s names and affiliations are not visible anywhere in the paper.
  • 2. Acknowledgements should be anonymized or removed during the review process.
  • 3. Self-citations should be included where necessary, but must use the third person. For example, "... as shown in our previous user study [2] ... " is not allowed, whereas "... as shown in Smith et al. [2] " is acceptable (because in this case the citation [2] will NOT be perceived as self-citation).

Failure to follow these guidelines may result in submissions being rejected without review.

Authors should also be aware of the SIGCHI Policy for Submission and Review at SIGCHI Conferences.

Paper Template

Submissions should follow the ACM Master Article Templates in a single column format. The paper should be anonymized and have line numbers on the left side of each page for review.

Authors are required to include a proper classification for the paper according to the ACM Classification System (CCS). Additional information on how to use it is available at:


Accepted full papers will be invited for oral presentation. Accepted short papers will be invited either as oral or poster presentation, depending on the nature and quality of the paper, and also on the suitability of the paper for presentation. Presenters will be asked to submit their presentation materials in advance of the conference, so that they can be checked for accessibility.
