The 2026 ACM SIGIR Conference on Human Information Interaction and Retrieval (CHIIR – pronounced “cheer”) will take place in Seattle, WA, USA, between 22 and 26 March 2026.

ACM SIGIR CHIIR 2026 invites submissions focused on user-centered approaches to designing and evaluating systems for information access, seeking, retrieval, and use. Contributions may explore improvements to existing systems and interfaces; propose novel theories, models, and systems; or focus on understanding individual and group interactions with information and information systems.

CHIIR is a multi-disciplinary research meeting. In addition to studies of interactive systems, information interaction, and retrieval, we encourage submissions on related topics, including human-human information interaction, novel interaction paradigms, new evaluation methods, and related research in a range of communities such as sociology, education, ethnography, psychology, human-computer interaction, and other relevant disciplines.

CHIIR 2026 will be held in person to enhance community building and foster meaningful discussions.

Collaborative information seeking and social search, including social utility and network analysis for information interaction
Insights and analyses related to human experiences and usage trends with recommendation technologies
Information interaction and seeking with mobile devices and services
Studies of the usage of generative AI for information interaction and retrieval
Information interaction and retrieval in the context of Digital Humanities
Ethical and societal aspects of information access
Gamification in interactive information retrieval


CHIIR 2026 will accept submissions of the following types: full papers, short papers, resource papers, perspective papers, demonstration papers, tutorials, workshops, doctoral consortium papers.

We will use the TAPS-based ACM workflow. Overall instructions are at this link. Specific requirements for each submission type are provided on their respective pages.

You can submit papers that you have posted to archival platforms (e.g. arXiv), or plan to post in the future, after submission. However, your paper must conform to the specifications outlined here.
