A graphical user interface (GUI) is described. The GUI includes first GUIelements that provide a visual representation of the nodes of an audio/videodevice. In response to user input, a signal is caused to be routed betweennodes by manipulating circuitry within the audio/video device. Second GUIelements provide a visual representation of the signals being routed within theelectronic device between pairs of first GUI elements (e.g., between nodes). Asa result, the user can readily understand which nodes are connected to each other. Thus, for example, a user can easily visualize which source node is providing input to a target node and, by selecting the appropriate GUI elements,can just as easily switch from one source to another or from one target to another. |
