Proximity based output selection for computing devices
In general, techniques are described for performing proximity-based output selection. A computing device comprising one or more network interfaces and processing circuitry may be configured to perform the techniques. The one or more network interfaces may communicate with one or more available outputs for playing content. The processing circuitry may determine a proximity to the computing device for each of the one or more available outputs, and determine, based on the proximity determined for each of the one or more available outputs relative to every other one of the one or more available outputs, a ranked list of available outputs. The processing circuitry may next interface, with a display, a graphical user interface that includes at least a portion of the ranked list of available outputs.
