We present X-Ray Audio, a communication system for creating and navigating geo-located audio conferences. Users elect to participate in hail channels arranged by proximity and intention. As participants pass from one locale to another, they may chat with a changing milieu of users relative to their location and can choose to hear each-others voices emanating from their relative directions, modulated by orientation and distance. We envision this form of communication to be particularly relevant to automotive applications where it can both provide enhanced situational awareness and establish an up to now impossible social bond between drivers, all the while remaining vehicle operation safe. This paper will provide a technical brief of the system as currently implemented and propose use cases for its deployment in automobiles.
