Goobo: A Multimodal, Context-Aware Dialogue Platform for Personalized Embodied Character Interaction

In-public companionship is underexplored, especially for ACG (anime, comics, and games) users who carry character goods and seek shared presence with favorite characters in everyday public life. We present Goobo, a lightweight multimodal companion embedded in an ita-bag (a transparent display bag used by ACG fans) that “activates” carried character goods via real-time visual perception and persona-consistent expressive narration. Informed by a formative workshop, Goobo illustrates a portable, character-bound interaction paradigm and serves as a platform for upcoming field studies on how users engage with activated characters in public settings.
