Call for Papers for the First Submission Round of  Full Papers and Technical Notes of EICS 2026: The 18th ACM SIGCHI Symposium on Engineering Interactive Computing Systems, 30 June - 3 July, 2026, Patras, Greece https://eics.acm.org/2026/ Submission deadline for the 1st Round of PACM EICS 2026 for Full Papers and Technical Notes: July 25, 2025 EICS 2026 is the eighteenth international ACM SIGCHI conference devoted to engineering interactive computing systems and their user interfaces, addressing one or more software quality factors, such as usability, user experience, reliability, security, etc. Work presented at EICS covers all stages of the engineering life-cycle of interactive systems - inception, requirements, design, specification, coding, data analytics, validation and verification, deployment and maintenance. EICS has the longest tradition of bringing together researchers who contribute to better ways of creating interactive computing systems, stemming from the conference on command languages in the seventies. The conference is best known for rigorously contributing and disseminating research results that hold the midst in between user interface design, software engineering and computational interaction. EICS focuses on models, languages, notations, methods, techniques and tools that support designing, developing, validating and verifying interactive systems. The conference brings together people who study or practice the engineering of interactive systems, drawing from design, HCI, software engineering, requirements engineering, software development, modeling, and programming. Submissions advance the state of the art of the engineering of interactive systems. Topics include, but are not limited to: *Modelling, specification and analysis of interaction and interactive systems *Requirements engineering for interactive systems *Methods, processes, principles and/or tools for building interactive systems (e.g., design, implementation, prototyping, evaluation, verification and validation, testing) *Software architectures for interactive systems *Formal methods within interactive systems engineering *Bridging the gap between engineering and design practices. *Engineering design and evaluation tools *Computational techniques for designing and evaluating interactive systems *Interactive data-driven systems *Explore and/or employ of diverse interaction techniques and devices (e.g., adaptive, context-aware, tangible, haptic, touch and multitouch input, voice, gestures, recognition of physiological signals, multimodal input, mobile and wearable systems, virtual, augmented, mixed and extended reality) *Engineering hardware or software integration in interactive systems (e.g., fabrication and maker processes, physical computing, cyber-physical systems) *Engineering interactive systems for diverse user groups (e.g., children, elderly, people with disabilities…) *Engineering collaborative multi-user interactive systems *Engineering interactive systems embedding AI-technologies *Engineering interaction-driven AI-technologies *Applying AI technologies in methods, processes and tools for building interactive systems in all stages of the engineering lifecycle A newcomer’s guide to EICS is available at https://dl.acm.org/doi/10.1145/3300960 ------------------------------------------------------------------------ FULL PAPERS and TECHNICAL NOTES SUBMISSIONS EICS Full Papers and Technical Notes are published as articles in the Journal Proceedings of the ACM on Human-Computer Interaction (PACM - EICS series). There are three submission deadlines per year, and authors can choose when to submit. Papers follow the traditional journal model of reviewing: papers may be accepted after submission and review, or may be recommended for revisions and re-submission to the next round to enable authors to refine papers based on reviewer recommendations. Submissions for the journal of this venue should present original and mature research work within the scope of the conference. Note that accepted journal papers can be either regular research papers, or technical notes. Technical Notes are shorter, more focused contributions, that focus specifically on system contributions and technical work. Elucidating technical details of complex interactive systems, preferably ensuring the work can be reproduced or put to practice, is a primary objective of a Technical Note. Tech Notes require an illustrative example of the system, and they can, but do not need to, be validated by formal user evaluations or user studies. Validation can also be done through e.g. simulation, feasibility, or comparisons. Tech Notes will be judged on their technical merits and relevance to interactive systems concerns. There are no length restrictions on Full Papers and Technical Notes, nor any limit to the number of references that may be included. We advise authors to ensure the length of their papers is in function of the contributions. Concise and clear is often to be preferred over lengthy and verbose. Full Papers and Technical Notes should be written in the ACM format, see https://www.acm.org/publications/authors/submissions Papers should comply with the ACM policy on Research Involving Human Participants and Subjects, see https://www.acm.org/publications/policies/research-involving-human-participa nts-and-subjects Submission deadline for the 1st Round of PACM EICS 2026 for Full Papers and Technical Notes: July 25, 2025 Papers are submitted using https://new.precisionconference.com PACM-EICS Full Papers and Technical Notes chairs for EICS 2026 Célia Martinie and Davide Spano
