Information retrieval using decoded machine-readable optical codes

摘要

A method is disclosed for reading a machine-readable optical code encoding information formed in an image that is presented to a user. The method includes using a processor to receive the image with the machine-readable optical code; using a graphic user interface to visually present the received image on a display; using the graphic user interface to receive a user selection of the machine-readable optical code; using a processor to decode the selected machine-readable optical code; and using the graphic user interface to present information referenced by the decoded information on the display.

主权项

1. A method comprising:
parsing, using a processing system, an electronic document to find an image element; analyzing, using the processing system, the found image element to determine if the found image element contains machine-readable optical code; presenting, on a graphical interface, an option to select the machine-readable optical code if the found image element contains the machine-readable optical code; decoding, using the processor, the selected machine-readable optical code; and presenting information referenced by the decoded information on the graphical interface.
