Sojeong presented two full papers at CHI `25

Sojeong presented her two full papers, “What If Smart Homes Could See Our Homes? Exploring DIY Smart Home Building Experiences with VLM-Based Camera Sensors” and “User Experience with LLM-powered Conversational Recommendation Systems: A Case of Music Recommendation,” at the CHI 2025 conference, Yokohama, Japan.

The first work conducted a three-week diary-based experience-prototyping study to explore users’ DIY smart-home-building experiences with VLM-based camera sensors. The study revealed three key findings: (1) participants’ expectations for VLM camera-based smart homes, (2) the impact of VLM camera-sensor characteristics on the DIY process, and (3) users’ concerns. Through the findings of this study, the paper proposed design implications to support the DIY smart-home-building process with VLM camera sensors and discussed living with intelligence.

The second work conducted a three-week diary study to explore the unique experiences that LLM-powered CRS can provide compared to traditional recommender systems (RS). The study revealed three key findings: LLM-powered CRS can (1) help users clarify implicit needs, (2) support unique exploration, and (3) facilitate a deeper understanding of musical preferences. Based on these findings, the paper discussed the new design space enabled by LLM-powered CRS and highlighted its potential to support more personalized, user-driven recommendation experiences.
