Designed an emotionally responsive IoT product that reinterprets a traditional Japanese object through contemporary technology. RIND. is an IoT-enabled wind chime that transforms the routine act of ventilation into a calming sensory experience. Inspired by lifestyle changes during the COVID-19 pandemic, the project explores how opening a window, often perceived as an inconvenient necessity, can become an emotionally rewarding ritual. Rather than using technology solely for functionality, RIND integrates environmental sensing with the cultural and emotional qualities of the traditional Japanese wind chime, creating an ambient experience that responds to natural wind conditions. I originated the concept and led the product design, focusing on balancing technological innovation with cultural heritage and emotional experience.
