OATs: AI version of Tamagotchi has arrived, everyday items instantly become virtual pets needing care

OATs system developed by Carnegie Mellon University student Jin Da Hua combines home items with virtual pet images, giving them emotional expression capabilities through electronic ink screens and sensors. The main module of the system costs about $20, virtual characters are generated by Gemini Nano Banana, and users can set trigger conditions through a web platform. Currently, OATs has a short battery life issue, with main application scenarios including item usage monitoring, status reminders, and habit tracking.
