Abstract
In general, techniques and systems for retrieving supplemental information associated with visual media are described. In one example, a method includes obtaining, by a computing device, position information from a position device using near-field communication (NFC), wherein the position information identifies a position of the position device in relation to a portion of visual media associated with the position device. The method may also include receiving, by the computing device, supplemental information that is provided by a networked device based at least in part on the position information, wherein the supplemental information comprises additional information related to the portion of the visual media. In some examples, the position device is included within an array of position devices mounted behind the visual media.
