Abstract
A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, and a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The directional sound emitter may emit ultrasonic waves configured to frequency convert to produce the audio. The communication interface may be configured to identify an entity of interest with which the user wishes to interact based on gestures and/or vocal emissions by the user and may automatically communicatively couple the user to the entity of interest. The hands-free intercom may determine whether remote entities requesting to communicatively couple with the user should be allowed to couple. The hands-free intercom may detect eavesdroppers and warn the user of the detected eavesdroppers.
