Abstract

A viewport lens displays registered information registered using embedded data. An image capture device captures an image from the substrate that includes embedded data. The embedded data in the captured image is decoded to create information regarding the substrate, such as location, orientation, or a label. Based on the information regarding the substrate, information is generated that is registered with the substrate. In one embodiment, the information is registered with the substrate by optically combining the generated information with substrate information in a viewport lens.

Claims

1. An apparatus for displaying registered information using embedded data, comprising:

an image capture device for capturing a first image of a substrate having first visible data and embedded data embodied thereon;

a decoder for decoding the embedded data to develop registration information;

a device for retrieving second information from a storage location identified by the registration information; and

a display for displaying a second image including second visible data representing the second information;

the second image being positioned relative to the first image based on the registration information such that an observer, by using the display, sees the first visible data of the first image and the second visible data of the second image spatially related to the first visible data of the first image wherein the display includes an optical device positioned relative to the substrate to enable the observer to view the first image on the substrate through the optical device;

the display displaying the second image in the optical device in order to spatially relate the second visible data in the second image to the first visible data in the first image.

2. The apparatus of claim 1, wherein the registration information includes a location on the substrate.

3. The apparatus of claim 1, wherein the registration information includes an orientation of the substrate.

4. The apparatus of claim 1 wherein the optical device is a lens.

5. The apparatus of claim 1 wherein the optical device is a semitransparent mirror.

6. The method of claim 1 wherein the second image is the same size as the first image.

7. The method of claim 1 wherein the second image is larger than the first image.

8. A method for displaying registered information using embedded data, comprising:

capturing a first image of a substrate having first visible data and embedded data embodied thereon;

decoding the embedded data to develop registration information;

retrieving second information from a storage location identified by the registration information; and

displaying, on a display, a second image including second visible data representing the second information; and

second image being positioned relative to the first image based on the registration information such that an observer sees the second visible data of the second image spatially related to the first visible data of the first image;

wherein the display includes an optical device positioned relative to the substrate to enable the observer to view the first image on the substrate through the optical device;

the display displaying the second image in the optical device in order to spatially relate the second visible data in the second image to the first visible data in the first image.

9. The method of claim 8, wherein the decoding step further comprises decoding the embedded data to identify a location on the substrate.

10. The method of claim 8, wherein the decoding step further comprises decoding the embedded data to identify a location on the substrate.

11. An apparatus for displaying registered information using embedded data, comprising:

an image capture device for capturing a first image of a substrate having first visible data and embedded data embodied thereon;

a decoder for decoding the embedded data to develop registration information;

a device for retrieving second information from a storage location identified by the registration information; and

a display for displaying a second image including second visible data representing the second information;

the second image being positioned relative to the first image based on the registration information such that an observer, by using the display, seed the first visible data of the first image and the second visible data of the second image spatially related to the first visible data of the first image wherein the first image having first visible data and the second image including second visible data are projected onto a projection surface such than an observer sees a composite image of the first and second visible data formed by the second image overlaid and registered with the first image.

12. A method for displaying registered information using embedded data, comprising:

capturing a first image of a substrate having first visible data and embedded data embodied thereon;

decoding the embedded data to develop registration information; and

displaying a second image including second visible data;

the second image being positioned relative to the first image based on the registration information such that an observer, by using a display, sees the first visible data of the first image and the second visible data of the second image spatially related to the first visible data of the first image;

wherein the display includes an optical device positioned relative to the substrate to enable the observer to view the first image on the substrate through the optical device;

the display displaying the second image in the optical device in order to spatially relate the second visible data in the second image to the first visible data in the first image.
