We present Visual Resonator (VR), an auditory interface that promises to provide an interactive realization of the Cocktail Party Phenomenon. The wearer of this interface can hear a voice or auditory information only from the direction in which he/she is facing, and can send his/her voice only in the direction towards which he/she is facing. In addition, individuals who are within sight of each other can have a conversation, even if they are not close enough to talk directly, since an infrared signal is used to transmit the auditory information.
