Image Trigger Database for Printed Media Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing alternative media content to readers of printed articles often rely on publishers' control and require users to manually enter URLs or scan QR codes, limiting user access to supplementary content.
Innovation Solution
A computer-implemented method that uses image triggers extracted from captured images to identify and provide alternative media content by crawling the web, generating digital fingerprints, and displaying corresponding content on user devices via Augmented Reality functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If web links or QR codes are included in printed articles to provide alternative content, then publishers can control the alternative content delivery, but user access is limited and requires manual interaction
Solution Approach 1:
The system performs preliminary actions by crawling the web and generating image triggers from alternative content before the user reads the printed article. These triggers are stored in a database and automatically recognized when the user captures an image of the article, eliminating the need for manual URL entry or QR code scanning.
Solution Approach 2:
The system enables self-service by automatically recognizing printed content through image capture and retrieving corresponding alternative content from the database. The user simply needs to capture an image of the article, and the system autonomously identifies the content and provides the alternative media without requiring manual interaction.
2Reliability
If image recognition is performed at the network server, then centralized processing can be achieved, but network bandwidth and server load increase
Solution Approach 1:
The system segments the image recognition process into two parts: image capture and trigger identification are performed locally on the user device, while alternative content retrieval is performed on the server. This segmentation reduces network bandwidth consumption by only transmitting the captured image for processing rather than transmitting large amounts of alternative content data over the network.
3Adaptability or versatility
If alternative content is provided through publisher-controlled links, then content accuracy can be maintained, but user independence and access flexibility are reduced
Solution Approach 1:
The system introduces an intermediary mechanism - the image trigger database - that connects printed content to alternative media without requiring publisher-controlled links. The database stores pre-generated triggers from alternative content and matches them with captured printed content, enabling user-independent access while maintaining content accuracy through automated recognition.
Data Source
AI summary
A computer implemented method is for providing user devices with alternative content. The method includes: defining a plurality of search parameters; crawling the world wide web or selected parts thereof, or searching predefined web sites, to identify content matching one or more of said search parameters; generating image triggers by extracting the identified content or generating digital fingerprints indicative of the identified content; storing the image triggers in a database, together with respective alternative content or alternative content identifiers; receiving an image captured from a printed or displayed medium at an end user device; searching the captured image to identify a presence of at least one of the image triggers in the captured image; and causing alternative content corresponding to the at least one of the image triggers to be displayed or presented at the end user device, or a respective other device associated with the end user device.
