TokTok

A Gentle Doorstep Notification System for Shared Living Environments

TokTok is a subtle notification system designed for shared spaces like dormitories and share houses, where individual focus and interpersonal communication must co-exist. To prevent the sudden startle of a loud, unexpected knock, the device filters external interruptions into soft, ambient visual cues, allowing users to maintain a deep and stable state of flow. By translating the visitor’s button-pressing patterns into distinct visual expressions of intent, TokTok reduces thoughtless distractions while clearly conveying necessary messages. Ultimately, it fosters a respectful and harmonious culture that honors each individual’s personal boundaries.
