Abstract
A system can use an on-screen digital character powered by an artificial intelligence framework to provide an interactive ambient display. The system may integrate a millimeter-wave radar sensor for camera-less presence detection and a far-field microphone array for acoustic event recognition of ambient household sounds. Based on data from these sensors, the digital character could, for example, acknowledge a user entering a room or react to specific sounds, such as music or a doorbell. This allows a display's idle screen on a computing device (e.g., a smart display, television, or tablet) to function as a dynamic, context-aware interface. The interface can proactively interact with its physical environment, potentially reducing a need for constant explicit commands or visual data capture.
