How Much Can AI Understand? Toward AI-Assisted Sensemaking of Collaborative Discussion in Groups with Shared History

AI tools that support collaborative discussion typically treat the discussion as a standalone task, focusing only on its content and setting aside the social context of the group having it. But it is groups with a shared history, with their own norms, hierarchies, and relationships, where the most tangled and complex discussions tend to arise. These discussions cannot be understood apart from that context, and AI that overlooks it risks failing to convey what a discussion means, or even misrepresenting it. Drawing on two studies of how experienced Wikipedia editors read and make sense of discussions, we propose an AI-Assisted Sensemaking Model for Collaborative Discussions, which captures not only a discussion's arguments but also the norms and participants behind it, along with the context that gives each meaning. In this model, the system supports the early stages of the sensemaking process, and the degree to which it performs interpretive work can range from low to high. We argue that higher interpretive work reduces the burden on users but increases their reliance on the system's judgment. We then discuss the risks of an insufficiently intelligible system, what it would take to make one more intelligible, and the safeguards it still requires.

How Designers Envision Value-Oriented AI Design Concepts with Generative AI

As AI integrates into design practice, designers increasingly use generative AI tools to envision AI-enabled solutions, positioning AI as both design tool and design material. This dual role creates recursive value tensions distinct from traditional design work. We engaged 18 designers in a concept envisioning activity and interviews to understand how they navigate values and recognize potential harms in this context. Our analysis reveals that (i) designers engage in reciprocal reflection-in-action with AI; (ii) this process surfaces multi-level value tensions across tool, designer, and concept; (iii) designers demonstrate greater attunement to harm recognition as a primary design signal than to articulating positive value fulfillment; and (iv) designers exercise anticipatory judgment through meta-design reasoning about how tool assumptions risk propagating into designed concepts and future use contexts. We extend Schon's reflection-in-action framework and discuss implications for redesigning AI-mediated design tools, supporting harm-centered reasoning, and positioning design as foundational to AI development.

Developing an AI Concept Envisioning Toolkit to Support Reflective Juxtaposition of Values and Harms

Early-stage concept envisioning is a critical juncture in AI design, shaping how designers frame problems and the decisions that follow. Yet values and potential harms are often too abstract or addressed too late to meaningfully shape design. Using a Research-through-Design (RtD) approach, we developed the AI Concept Envisioning Toolkit, comprising an AI Capability Library, 24 Value--Harm Cards, and a Value--Tension Map, to support reasoning by juxtaposing values and harms within AI technical capabilities. Through a survey with 30 designers and in-depth interviews with 12 designers, we find that the toolkit is clear and perceived as valuable, and that it encourages value reflection, helps anticipate potential harms, and makes ethical considerations more transparent in early-stage design. We reflect on our design process and discuss design approaches for tools that promote reflection on values and potential harms, surface and navigate value tensions, and introduce productive friction throughout design workflows.

Popularity Without Legitimacy? Comparing Trust in Television Meteorologists and YouTube Weatherfluencers

During severe weather events, people must interpret rapidly evolving information to make time-sensitive safety decisions. Broadcast meteorologists have traditionally served as credentialed intermediaries within established media organizations, while independent "weatherfluencers" on YouTube have emerged as prominent real-time interpreters for large and growing audiences. This mixed-methods study provides one of the first empirical comparisons of how viewers evaluate broadcast meteorologists against YouTube weatherfluencers across credibility, legitimacy, objectivity, and practical utility. Broadcast meteorologists were consistently rated higher on credibility, legitimacy, and safety utility, while weatherfluencers achieved parity on objectivity. Yet weatherfluencer audiences continue to grow, revealing a critical decoupling between audience attention and official or professional authorization that existing crisis communication models do not fully account for. Qualitative findings illuminate the mechanisms underlying these judgments and their implications for emergency communication in hybrid information ecosystems.

Making Sense of the Weather, Together: Collaborative Sensemaking in Severe Weather Livestreams

This paper examines collaborative sensemaking during severe weather events through the emerging phenomenon of "weatherfluencers" or content creators who livestream meteorological interpretation on platforms like YouTube. Drawing from sensemaking theory, crisis informatics, and platform studies, we analyze how these creators navigate the sociotechnical dynamics of interpreting severe weather in real time with distributed audiences. Through critical incident analysis of 13 Particularly Dangerous Situation (PDS) storm warnings across three prominent weatherfluencers, we identify three key practices: multi-source information triangulation, temporal bridging techniques, and platform-specific adaptations that transform entertainment interfaces into safety-critical communication channels. Our analysis shows how these practices challenge existing models of crisis communication by integrating distributed expertise, collapsing temporal frames, and reconfiguring platform affordances. This research contributes to understanding how informal emergency communicators mediate between institutional alerting systems and public needs, and how visual, multimodal crisis communication differs from text-centered approaches.

A Framework for AI-Supported Mediation in Community-based Online Collaboration

Online spaces involve diverse communities engaging in various forms of collaboration, which naturally give rise to discussions, some of which inevitably escalate into conflict or disputes. To address such situations, AI has primarily been used for moderation. While moderation systems are important because they help maintain order, common moderation strategies of removing or suppressing content and users rarely address the underlying disagreements or the substantive content of disputes. Mediation, by contrast, fosters understanding, reduces emotional tension, and facilitates consensus through guided negotiation. Mediation not only enhances the quality of collaborative decisions but also strengthens relationships among group members. For this reason, we argue for shifting focus toward AI-supported mediation. In this work, we propose an information-focused framework for AI-supported mediation designed for community-based collaboration. Within this framework, we hypothesize that AI must acquire and reason over three key types of information: content, culture, and people.

Perception in Pixels: Effects of Avatar Representation in Video-Mediated Collaborative Interactions

Interactive collaborative video is now a common part of remote work. Despite its prevalence, traditional video conferencing can be challenging, sometimes causing social discomforts that undermine process and outcomes. Avatars on 2D displays offer a promising alternative for enhancing self-representation, bridging the gap between virtual reality (VR) and traditional non-immersive video. However, the use of such avatars in activity-oriented group settings remains underexplored. To address this gap, we conducted a mixed-methods, within-subject study investigating the impacts of avatar-mediated versus traditional video representations on collaboration satisfaction and self-esteem. 32 participants (8 groups of 4 with pre-established relationships) engaged in goal-directed activities, followed by group interviews. Results indicate that avatars significantly enhance self-esteem and collaboration satisfaction, while qualitative insights reveal the dynamic perceptions and experiences of avatars, including benefits, challenges, and factors influencing adoption likelihood. Our study contributes to understanding and implications of avatars as a camera-driven representation in video-mediated collaborative interactions.
