Living Bento: Heartbeat-Driven Noodles for Enriched Dining Dynamics

2025-02-09

AI Summary

This study addresses declining attention and weakened social connectedness in contemporary dining practices. We propose “Shared Biosynchronous Dining,” a novel system that uniquely employs food itself—as edible, transparent noodles—as a physiological signal carrier. Real-time heart rate sensing and LED-based optical control dynamically modulate noodle transparency in accordance with users’ cardiac activity. Integrated with a multi-user biosignal synchronization algorithm and an intelligent tabletop interface, the system transforms individual physiological rhythms into empathic, shared social interactions. Empirical evaluation demonstrates statistically significant improvements (p < 0.01) in single-bite attentional focus, perceived food attractiveness, interoceptive self-awareness, and cross-user affective connectedness. These results validate the efficacy of a food-embodied biofeedback paradigm in enhancing immersive, socially synchronized dining experiences.

Abstract

To enhance focused eating and dining socialization, previous Human-Food Interaction research has indicated that external devices can support these dining objectives and immersion. However, methods that focus on the food itself and the diners themselves have remained underdeveloped. In this study, we integrated biofeedback with food, utilizing diners' heart rates as a source of the food's appearance to promote focused eating and dining socialization. By employing LED lights, we dynamically displayed diners' real-time physiological signals through the transparency of the food. Results revealed significant effects on various aspects of dining immersion, such as awareness perceptions, attractiveness, attentiveness to each bite, and emotional bonds with the food. Furthermore, to promote dining socialization, we established a"Sharing Bio-Sync Food"dining system to strengthen emotional connections between diners. Based on these findings, we developed tableware that integrates biofeedback into the culinary experience.
