Have you noticed the rise of decentralized social media like Mastodon? 🌐
In our #CSCW2025 paper, we studied how people perceive and manage their feeds on Mastodon — and what it means for designing tools in future decentralized social platforms.

🎤How do you use home/local/federated timelines on Mastodon? We're researchers from Princeton University, and we're conducting a study about how people use Mastdon’s feeds.

We built StopGap, a prototype that explains jargon in videos in various knowledge representation formats (definitions, metaphors, lists, and images), and tested it out through a design probe study (N=24)

Findings? 📈
- StopGap provides real-time support and improves understanding without raising cognitive load.
- No "one-size-fits-all" knowledge representation formats: user preference depends on the context, the word, and their own habits and backgrounds.
- Participants want a balance between user-initiated and automated support, along with personalization and just-in-time assistance.
Replying to
We map out a design space for real-time LLM knowledge support systems, and discuss design implications for 1) balancing automation vs user control, 2) building trust in AI-generated info, 3) personalizing knowledge support, and 4) generalizing jargon explanation to other knowledge support

This work was done when I was a summer intern at Accenture Labs, together with my awesome collaborators Aadit Shah, Jordan Ackerman, and Manaswi Saha.
Sadly, none of us will be in Japan — but we'll present online at the "Narratives and AI Support" session (https://programs.sigchi.org/chi/2025/program/session/197232) on Thursday, May 1, 9AM!
