Abstract

Systems and methods herein describe transmitting metadata to an augmented reality device using inaudible frequencies by receiving a first stream of inaudible sound waves in real-time, generating a first binary representation of the first stream of inaudible sound waves, generating a first set of metadata based on the first binary representation, generating a first plurality of augmented reality content items based on the first set of metadata, causing display of the first plurality of augmented reality content items on a display device coupled to the head-wearable apparatus as the first stream of inaudible sound waves is being received.
