This paper examines why people use LLMs for fortunetelling and how such interactions affect them. Through an analysis of 1,045 Chinese social media posts and interviews with 20 users, the study finds that LLM fortunetelling is used less for accurate prediction than for coping with uncertainty and seeking emotional support. Although it rarely changes users’ major beliefs or decisions, it can subtly shift their mindset and lead to small behavioral adjustments.

This paper asks a simple but important question: when do graphical explanations actually help people reason with LLMs? Through a 204-participant study, it finds that turning dense LLM rationales into interactive argument maps can improve trust calibration in some tasks, but hurt it in others. Strikingly, the explanation format users prefer is not always the one that helps them make better decisions, showing that effective AI explanations must be matched to the task.

This paper addresses a key limitation of free-hand robot teleoperation: human wrist motion cannot fully exploit robotic arm dexterity. Based on 60 demonstration videos, the authors identify three robotic motion capabilities that exceed human biomechanics and propose four VR-inspired interaction techniques to extend users’ control. Evaluations in VR and on a UR5 robot show that these techniques improve rotation, alignment, and orientation control while reducing operator workload.

When we describe our needs to LLMs, we often know what we want internally, but struggle to articulate our needs and intentions clearly and precisely through language. To address this challenge, we propose Adaptive Prompt Elicitation, which adaptively selects visual queries to help AI quickly refine human intent. This approach significantly improves human intention alignment while introducing no additional workload.

Expressing prior beliefs is a critical step in Bayesian analysis—but translating intuitive knowledge into statistical distributions is notoriously difficult. We introduce PriorWeaver, an interactive system that lets analysts visually construct datasets to express their assumptions. By turning intuitive beliefs into data and iteratively refining them through prior predictive checks, PriorWeaver helps analysts produce priors that better match their expectations.

Hate speech moderation often focuses on offenders and targets—but what about the silent majority watching the conversation? We build Civilbot, a counterspeech bot designed to intervene in online discussions, and study how it influences bystanders. Our results show that reason-based counterspeech delivered with a positive tone is most effective, revealing how well-designed bots can subtly mobilize bystanders and shape healthier online discourse.

Online discussions promise collective knowledge building—but many stall at shallow exchanges. We design an LLM-powered facilitation agent that strategically intervenes to help conversations dig deeper. Through a study with 60 participants across multiple discussions, we show that AI interventions can push discussions from surface-level sharing toward deeper reasoning and synthesis, revealing how AI can sustain more meaningful online discourse.

Traditional Medicine (TM) has long served as a cornerstone of healthcare, yet its integration with AI remains limited. Through interviews with 16 TM clinicians, we explore how AI-powered clinical systems are perceived and used in practice. Our findings reveal low adoption due to TM’s unique diagnostic logic and data challenges. We discuss these barriers and propose ways to better align AI innovations with the realities of traditional medicine.

What happens when you disagree with your AI collaborator during decision-making? We explore how to resolve such conflicts by leveraging the power of Retrieval-Augmented Generation. Acting as a communication bridge, a large language model enables deliberation between human decision-makers and domain-specific smaller models, significantly improving decision quality in the face of disagreement.

Can AI-generated digital humans serve as a form of digital legacy—allowing us to “live on” in this world? Our comprehensive qualitative analysis investigates the full lifecycle of the “AI afterlife,” shedding light on how society envisions—and grapples with—this future.

Co-designed with clinicians, our system uses dynamic graph-based conversation flows and context-aware scaffolding to adaptively guide interviews. It outperforms existing solutions in both data accuracy and user experience, offering a promising path for AI-assisted healthcare interactions.

We promote human-AI hybrid intelligence from the perspective of mutual understanding between humans and AI. This paper systematically introduces our previous work on enabling human-AI hybrid intelligence by enhancing human understanding of AI, AI’s understanding of humans, and humans’ self-understanding.

AI is often used as a recommender in decision-making, but this can reduce human analytical thinking and cause over-reliance on AI.
