Abstract

A method of revealing hidden content associated with printed content using a handheld display device. The method includes the steps of: imaging an area of a printed substrate and generating image data using an image sensor; determining interaction data using the image data; retrieving display data using an identified page description, the display data including the hidden content associated with the printed content; displaying, on an opaque touch-sensitive display screen of the handheld display device, display information based on the display data and including the hidden content. The opaque display screen has real-time virtual transparency through the screen to the printed content from a user'"'"'s perspective to provide a virtual window to the printed content. The opaque display screen additionally displays the hidden content in real-time as if it were printed on the printed substrate.

Claims

a short-range wireless transceiver and a mobile phone transceiver.

17. The handheld display device of claim 13, wherein said interaction data identifies a position of the device relative to the printed substrate and said retrieved display data corresponds to a part of the substrate containing said position.

18. The handheld display device of claim 13, wherein said device comprises a memory for storing the retrieved display data.

19. The handheld display device of claim 13, wherein said printed content infers the presence of said hidden content.

20. An interactive application for execution on a handheld display device having an image sensor, a processor and an opaque touch-sensitive display screen, the interactive application being configured to operatively control the device so as to perform the steps of:

imaging an area of a printed substrate and generating image data using the image sensor of the handheld display device, the imaged area of the printed substrate containing printed content;

determining interaction data using said image data, said interaction data identifying a page description corresponding to at least part of the printed substrate;

retrieving display data using the page description, said display data including hidden content associated with the printed content;

displaying, on the opaque touch-sensitive display screen, display information at least partially based on said display data, said display information including the hidden content, wherein the opaque touch-sensitive display screen has real-time virtual transparency through the screen to the printed content from a user'"'"'s perspective to provide a virtual window to the printed content, and wherein the opaque display screen additionally displays the hidden content in real-time as if it were printed on the printed substrate.
