Systems, methods, and devices are disclosed for operating a user communication device (12) having a mute function. The systems, methods, and devices allow for the mute function to be controlled in accordance with a facial orientation of the user. In one exemplary embodiment, a controller (28) is operably associated with a camera (18) and a user communication device (12). The controller (28) may be internal to the user communication device (12) or may be external in an ancillary device (20). The controller (28) is configured to obtain a visual representation that includes a facial image of a face of a user captured with the camera (18). To determine facial orientation data that indicates a facial orientation of the face from the facial image, the controller (28) implements an image processing function on the visual representation. The controller (28) controls the mute function of the user communication device (12) based on the facial orientation data extracted from the visual representation. |
