1. A system for accessing mixed media reality document data structures, the system comprising: a mixed media processor for receiving, from a device, an image patch of a commercially printed document that includes a hotspot designation location, the image patch comprising at least a portion of an entire page of the commercially printed document that includes the hotspot designation location, for extracting features from the image patch including generating a histogram to discriminate between text and non-text, for determining a mixed media reality document data structure that corresponds to the image patch based on extracted features and the histogram, for capturing an x-y location of a hotspot in response to receiving a print command by identifying a begin mark designating a beginning point of the hotspot designation location and an end mark designating an ending point of the hotspot designation location, the begin mark and the end mark being represented by a visually imperceptible font, for instructing the device to highlight the hotspot based on the determining of the mixed media reality document data structure and for retrieving the mixed media reality document data structure, the mixed media reality document data structure comprising: a representation of the portion of the commercially printed document corresponding to the image patch; a supplemental media associated with the image patch; and the hotspot that is sent for display along with the representation, the hotspot comprising a pointer to the supplemental media, such that the supplemental media is sent in response to receipt of an indication that a user selected the hotspot.
