HeartSway: Exploring “Personal Data Traces” as Poetry in Public Space
HeartSway: Exploring Biodata as Poetic Traces in Public Space
HCI Today summarized the key points
- •This article introduces HeartSway, a system that turns biodata—such as heartbeats and body movement—into traces in public spaces.
- •In HeartSway, a public hammock stores a person’s heartbeat and body movement, and the next user experiences it through vibration and swaying.
- •A study with 10 users found that the device created comfort and curiosity, helping participants feel a quiet sense of connection even with strangers.
- •Participants said the experience felt less burdensome because it was anonymous and time-shifted, and they reported imagining others’ emotional states and acting with consideration.
- •The research suggests that biodata can create warm mutual understanding and a sense of community among strangers in public spaces.

Why Read This from an HCI Perspective
This article is especially meaningful for HCI/UX practitioners and researchers because it frames biodata not as numbers or health metrics, but as “experience material” that leaves traces of real people. In particular, it shows how, in public spaces, data from strangers can be communicated while balancing anonymity, emotional resonance, and room for interpretation. Even in AI-enhanced services, it prompts us to rethink trust, intervention, and privacy design.
CIT's Commentary
What’s interesting is that this work prioritizes “how it makes people feel” over “accurate measurement.” Instead of presenting heartbeats and subtle movements as-is, it transforms them into vibration and swaying—leaving behind a sense of a stranger’s presence. Although the translation sounds technically simple, the actual experience can vary dramatically depending on how safe and comfortable users feel, and how far they consider the signals to be understandable. The key is striking a balance: creating a sense of connection without compromising safety and privacy in public spaces. In the context of domestic services, “non-intrusive intervention” may matter more than “warmth.” If this were applied to services from Naver, Kakao, or local startups, then when experimenting with such mechanisms, you would need to design intervention pathways more clearly—such as state transparency, data retention practices, and exactly when and how users can disengage and exit.
Questions to Consider While Reading
- Q.When users use this experience for a long time, will they interpret the anonymous traces of others as a “warm connection,” or will repeated exposure dull them like background noise?
- Q.When handling biodata traces like this in public spaces, what is the minimum information that should be explained to users first?
- Q.If this kind of design were applied to domestic campuses, cafes, or subway waiting areas, how might cultural differences change interpretation and acceptance?
