1. An apparatus for processing printed material comprising:
- a pre-processing module for optically scanning printed text and generating pre-processed patterns for sub-regions of the printed text, each pre-processed pattern including a unique signature;
an input module for pointing to a designated location in the printed text and generating a designated localized sub-image including a pattern with a unique signature corresponding to the designated location;
a comparison module for comparing the pattern of the designated localized sub-image to the pre-processed patterns for sub-regions of the printed text to locate the designated localized sub-image in the pre-processed patterns for sub-regions; and
an output module for associating the located designated localized sub-image with a predetermined external action.

Abstract
Apparatus and methods are disclosed for processing printed material to provide an index of locations within the printed material that can be associated with external actions such as displaying a graphical image, providing an audio or video output, or providing a multimedia output. The associations are stored in a database. Apparatus and methods are also disclosed that allow a user to image the printed material and by indicating a desired location within the printed material can cause one of the associated actions to be executed.
