Just completed our 7th joint talk at CHI — a precious collaboration that started during our undergraduate years, exploring Human-AI interaction for human communication. We would like to thank ACES, Inc., a Japanese startup, for offering us an interesting field for a case study.

Very inspiring talk!. User simulators can be a powerful tool for evaluating systems. I'm curious to see how the applications will expand.

I was honored to give the closing keynote at the Everyday AR through AI-in-the-Loop workshop at #chi2025 yesterday on simulated users. In a nutshell: training user models directly in simulators enables tackling more realistic problems and opens up new applications.

In our new #IMWUT paper, we present PrISM-Q&A, an approach to augmenting voice assistants with sensed activity context for procedural tasks like cooking, latte-making, skin care, etc. The assistant can answer spontaneous questions like "What's next?" with only a smartwatch ⌚️🤖

#UIST2024 vision talks are so inspiring, making us think about the relationship between intelligence from both interface and social perspectives. Open questions ahead on how to design and implement mixed-intiative systems over time. (must cite for my future PrISM projects💪)

At UIST, we'll present PrISM-Observer, a proactive intervention agent based on the sensed context (e.g., reminder). How can we design timely interventions based on imperfect sensing with a smartwatch alone? (2/5). paper: video:
