Handheld display device having processor for rendering display output to provide real-time virtual transparency
First Claim
1. A handheld display device for interacting with printed content, said device comprising:
- an optical sensor for imaging an area of a printed substrate containing the printed content and generating image data;
an opaque touch-sensitive display screen for displaying display output to a user; and
a processor configured for;
monitoring the identity of the substrate and the position of the device relative to the substrate using the image data;
retrieving display data based on the position of the device relative to the substrate;
rendering the display output to the touch-sensitive display screen, said display output being at least partially based on the retrieved display data; and
interpreting user input captured via the touch-sensitive display screen;
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.

Abstract
A handheld display device for interacting with printed content. The device includes: an optical sensor for imaging an area of a printed substrate containing the printed content and generating image data; an opaque touch-sensitive display screen for displaying display output to a user; a processor configured for: monitoring the identity of the substrate and the position of the device relative to the substrate using the image data; retrieving display data; rendering the display output to the display screen; and interpreting user input captured via the display screen. 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.

8. An interactive application stored on a non-transitory computer-readable medium, said interaction application being configured 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:
-
monitoring the identity of the substrate and the position of the device relative to the substrate using the image data; retrieving display data based on the position of the device relative to the substrate; rendering the display output to the touch-sensitive display screen, said display output being at least partially based on the retrieved display data; and interpreting user input captured via the touch-sensitive display screen, wherein the interactive application is configured to operatively control the device such that 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. - View Dependent Claims (9, 10)

11. A method of interacting with printed content using a handheld display device, said method comprising the steps of:
-
imaging an area of a printed substrate and generating image data using an image sensor of the handheld display device, the imaged area of the printed substrate containing the printed content; monitoring the identity of the substrate and the position of the device relative to the substrate using the image data; retrieving display data based on the position of the device relative to the substrate; rendering display output to an opaque touch-sensitive display screen of the handheld display device, said display output being at least partially based on the retrieved display data; and interacting with said display output via the touch-sensitive display screen, 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. - View Dependent Claims (12, 13)
