1. A mobile electronic device for a headset including a holder configured to releasably retain the mobile electronic device in a defined pose relative to the headset, the mobile electronic device comprising:
a camera configured to output digital pictures and arranged by the holder to view a portion of the headset;
a display device arranged by the holder to display information for viewing by a user wearing the headset;
a processor operationally connected to the camera and to the display device; and
a memory storing program code that is executed by the processor to perform operations comprising:
processing a digital picture from the camera to identify a pose relative to the camera of an optically identifiable feature of the headset within the digital picture that was captured by the camera while the mobile electronic device is retained by the holder; and
controlling where graphical objects are rendered on the display device based on the identified pose relative to the camera of the optically identifiable feature within the digital picture.
