SoundOff is a passive sensing system developed at Georgia Tech that uses small, precisely shaped stainless steel tags to emit ultrasonic signatures when physically struck, enabling smart home interaction tracking without cameras, batteries, or machine learning. The system addresses privacy and infrastructure concerns by relying on physics-based acoustic design rather than electronic sensors or recording devices.
