1. A method for use by a game system including a processor in communication with a visual recognition device, the method comprising: receiving, by the processor, data corresponding to a user selected content; generating, by the processor, a vision recognition reference from the data; associating, by the processor, a user selected game behavior descriptor with the vision recognition reference, wherein the game behavior descriptor corresponds to a game behavior instance; storing, by the processor, the vision recognition reference and the associated game behavior descriptor in a database, wherein the database includes a plurality of pre-defined vision recognition references, and wherein each of the plurality of pre-defined vision recognition references corresponds to at least one pre-defined game behavior descriptor; receiving, after the storing, an image captured by the visual recognition device corresponding to a displayed image presented by a user during playing a game; matching the image captured by the visual recognition device with the vision recognition reference; retrieving, in response to the matching, the associated game behavior descriptor associated with vision recognition reference from the database; and performing in the game, in response to the receiving of the image, the game behavior instance corresponding to the associated game behavior descriptor.
