Claim 15:
16. A method, comprising:
generating image data by a camera of a first mobile device;
providing image metadata in a coordinate system for first mobile device for the image data by one or more sensors of the first mobile device;
transmitting the image data and the image metadata from the first mobile device to one or more servers;
transmitting a request for graphics to be displayed by the first mobile device over a view of a venue from the first mobile device to one or more servers;
receiving at the first mobile device from the one or more servers a transformation between a coordinate system the first mobile device and a real world coordinate system;
receiving at the first mobile device from the one or more servers the requested graphics;
converting by the first mobile device of the requested graphics into the first mobile device's coordinate system based on the transformation between the first mobile device's coordinate system and a real world coordinate system;
presenting the requested graphics over the view of the venue by the first mobile device;
determining by the first mobile device of whether the transformation between the first mobile device's coordinate system and the real world coordinate system has an accuracy within a threshold value; and
in response to determining that the accuracy of the update of the transformation is not within a threshold value, issuing by the first mobile device of a request to the one or more servers for an updated transformation from the first mobile device's coordinate system to the real world coordinate system.
