AR Overlay for Printed Document Revision Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of printed documents cannot access the latest contents or revisions without obtaining the updated version, as confidential information is obscured and updates are not reflected in previous printed copies.
Innovation Solution
An image processing apparatus and method that generates additional images showing differences between document revisions, which are registered with marker images, allowing a terminal device to overlay these images on photographed printed documents, enabling users to view the latest document contents through augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If confidential information is obscured in printed documents for security, then security is improved, but users cannot access the latest document contents
Solution Approach 1:
The patent transitions document information from a static 2D printed form to a dynamic multi-dimensional AR experience. By overlaying virtual images showing latest document contents onto the physical printed document, the system adds a temporal and informational dimension without altering the secure printed base layer.
Solution Approach 2:
The patent introduces an intermediary AR system that mediates between the secure printed document and the user's need for latest information. The AR overlay acts as a mediator, providing access to updated contents while leaving the original secure printed document unchanged.
2Loss of information
If users obtain updated document versions, then information currency is improved, but security risks increase
Solution Approach 1:
The patent segments document information into two distinct layers: the secure printed base layer and the dynamic AR overlay layer. This segmentation allows the information to be divided such that the printed portion maintains security while the AR portion provides currency, with each layer serving its specific function independently.
Solution Approach 2:
The patent applies different quality characteristics to different parts of the document system. The printed document maintains high security and stability, while the AR overlay provides dynamic, updated information. Each layer has optimized properties suitable for its specific purpose.
3Loss of information
If AR overlays are added to printed documents, then document update visibility is improved, but device complexity increases
Solution Approach 1:
The patent makes the terminal device universal by enabling it to perform multiple functions: photographing the printed document, recognizing marker images, retrieving AR overlay data, and displaying the composite view. This multi-functionality consolidates what could be separate complex systems into a single integrated device.
Solution Approach 2:
The patent uses copying by capturing an image of the printed document via photographing and then overlaying virtual AR images onto this captured image. This approach avoids the need for direct electronic access to the document, simplifying the system architecture while achieving the desired effect.
4Loss of information
If marker images are registered with multiple revision stages, then document revision tracking is improved, but data storage requirements increase
Solution Approach 1:
The patent performs preliminary action by pre-registering marker images with their associated revision stage information in a database before the AR display is needed. This advance preparation enables quick retrieval and overlay during actual use, avoiding the need for complex real-time analysis.
Data Source
AI summary
A processor of an MFP generates a first additional image based on an image in a designated region of a document. Furthermore, the processor of the MFP generates a second additional image showing a difference between the document and a document before revision of the document. Then, the processor of the MFP registers the first additional image and the second additional image on a server in association with a marker image showing the revised edition number of the document.
