Abstract
A viewer (100) is provided which senses machine-readable coded data (202), decodes the coded data (202), transmits the decoded data to a computer system, and receives in response from the computer system display data for display on a screen (102) and/or for playback via a speaker (106).
Claims17
A method for displaying on a screen of a viewer enhanced representations of segments of a printed substrate, wherein the viewer includes an optical sensor and wherein the printed substrate includes both coded data invisible to the human eye and data that is visible to the human eye, the method comprising the steps of:
- placing the viewer over a first segment of the printed substrate;
- sensing with the optical sensor first invisible coded data that is printed on the first segment of the printed substrate, wherein the first invisible coded data indicates both its own position on the printed substrate and an identity of the printed substrate;
- generating from the first invisible coded data a first visible image on the screen of the viewer, wherein the first visible image corresponds to the visible data printed on the first segment of the printed substrate that is beneath the viewer;
- moving the viewer over a second segment of the printed substrate;
- sensing with the optical sensor second invisible coded data that is printed on the second segment of the printed substrate, wherein the second invisible coded data indicates both its own position on the printed substrate and an identity of the printed substrate;
- and
- generating from the second invisible coded data a second visible image on the screen of the viewer, wherein the second visible image corresponds to the visible data printed on the second segment of the printed substrate that is beneath the viewer.
