Hi everyone, We want to invite you to participate in our Theory of Mind in Human-CUI (Conversational User Interface) Interaction Workshop <https://tominhai-cui2025.github.io/>. This in-person workshop will be held in conjunction with ACM CUI 2025 <https://cui.acm.org/2025/>, July 8-10 in Waterloo, ON, Canada. We just extended our paper deadline to June 14th AoE and we are open to a variety of submissions, including "encore" of published work. Please see the detailed CFP below. Thank you! *CFP: ToMinHAI@CUI 2025 — Workshop on Theory of Mind in Human-CUI Interaction* *Submission Deadline:* June 2, 2025 *Extended! June 14, 2025, AoE* *Workshop Website:* https://tominhai-cui2025.github.io/ *Email Contact*: qiaosiw@andrew.cmu.edu Recent advancements in AI are enabling conversational user interfaces (CUIs) to communicate with humans at various social capacities, transforming the way humans interact with AI agents through natural conversations. To enhance these conversational interactions, many researchers are turning to a key cognitive-social capability that enables interpersonal communication–Theory of Mind (ToM), our capability of attributing mental states such as goals, emotions, and beliefs to ourselves and others. As part of the ToMinHAI workshop series, this ToMinHAI workshop at CUI aims to examine the current practices, challenges, and opportunities in designing, building, and evaluating ToM in human-CUI interactions. To support interdisciplinary discussions, we warmly invite academic and industry researchers and practitioners in disciplines including but not limited to cognitive science, AI, HCI, design, machine learning, robotics, psychology, communication studies, and more to submit work that will inform our understanding of ToM in human-CUI interaction. We aim to explore three broad topics to inspire workshop discussions: - Building and measuring a CUI’s ToM-like capabilities, - Understanding and shaping human's mental state attributions to CUIs, and - Exploring the design and consequences of Mutual Theory of Mind in human-CUI interactions We encourage academic and industry researchers from various disciplines to contribute position papers, short literature reviews, encore of published work, and in-progress empirical studies to shape the discourse around ToM in human-AI interaction. **We are especially interested in short position papers that make an argument for a viewpoint or perspective about what should be done in ToM in human-CUI interaction to advance the current research and industry landscape.* *Submissions are encouraged, but not limited to, the following topics: - Conceptual discussions of ToM in human-CUI interaction, including how to define and measure ToM in both human and CUIs during interactions - Design of CUIs ToM-like capabilities that could influence user perceptions of CUIs - Empirical evaluations of humans’ mental state attribution behaviors (e.g., beliefs, blame) to CUI - Technical approaches for operationalizing, building, and measuring CUI’s ToM-like capability - Critical examinations of the impact of MToM-enabled human-AI interactions Papers should be submitted via OpenReview and will be evaluated based on quality and relevance to ToM in human-CUI interaction. All papers will undergo a single-blind peer review (i.e. author names and affiliations should be listed). Upon acceptance, papers will be published on the workshop website (all accepted submissions will be non-archival). *Please submit your papers to OpenReview:* https://openreview.net/group?id=ACM.org/CUI/2025/Workshop/ToMinHAI *IMPORTANT DATES* Paper Submissions: June 2, 2025 Extended!
