Mobile Terminal Barcode Identification via Display Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods require additional hardware and operations to access information from 2-D barcodes embedded within webpages, creating inconvenience for users as they cannot be identified directly on the mobile terminal's display interface.
Innovation Solution
A method and device that enable the identification of 2-D barcodes within a retrieved webpage by launching a browser, receiving user instructions, determining the availability of barcodes, obtaining and identifying the barcode images, and extracting associated information, either directly or indirectly through a remote server, using a processor with circuitry and memory units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user uses a built-in camera of a second mobile terminal to take a picture of the 2-D barcode image contained within the visited website, then the 2-D barcode image can be identified and information can be accessed, but additional hardware requirement and additional operations create inconvenience to user's experience
Solution Approach 1:
The mobile terminal uses its own display interface to present the 2-D barcode image, allowing the terminal itself to serve the function of barcode identification without requiring external hardware or manual operations. The system automatically detects and identifies barcodes from the display interface, eliminating the need for users to use additional cameras or perform manual scanning operations.
Solution Approach 2:
The display interface of the mobile terminal is made multi-functional by enabling it to not only display web content but also to serve as the interface for barcode identification. This allows the same hardware component (display interface) to perform multiple functions: displaying webpage content and providing the interface for automatic barcode detection and information access.
2Reliability
If a user takes a picture of the 2-D barcodes image using a built in camera on the mobile terminal, then the 2-D barcodes image can be sent to another website for identification, but the process requires additional operations and cannot directly access information from native 2-D barcodes within the webpage
Solution Approach 1:
The system performs preliminary detection and identification of 2-D barcodes directly from the display interface before the user needs to access the information. The barcode detection mechanism operates automatically in the background, pre-identifying barcodes so that when the user views the webpage, the information can be accessed immediately without requiring manual picture taking or additional processing steps.
Solution Approach 2:
The invention extracts the barcode identification function from the external camera-based system and integrates it directly into the display interface processing. By taking out the dependency on external camera operations and embedding the identification capability within the display interface, the system eliminates the time-consuming steps of manual picture capture and external processing.
3Ease of operation
If the mobile terminal uses its display interface to present the 2-D barcode image, then direct identification is enabled without additional hardware, but the system must determine barcode availability and obtain barcode images from the webpage
Solution Approach 1:
The system introduces an intermediary processing layer between the display interface and the barcode identification function. This intermediary mechanism automatically detects, extracts, and processes barcode images from the display interface, serving as a mediator that bridges the display functionality and the identification capability without requiring complex manual intervention or additional hardware.

AI summary
A method and device for identifying 2-dimensional (2-D) barcodes contained within a retrieved webpage are disclosed. The method includes the operations of: launching a browser to retrieve at least one webpage; receiving an instruction input by a user for identifying at least one 2-D barcode contained within the at least one retrieved webpage; determining according to the input instruction, whether the at least one 2-D barcode may be available within the at least one retrieved webpage; if the at least one 2-D barcode may be available within the at least one retrieved webpage, obtaining at least one 2-D barcode image; and identifying the least one 2-D barcode image, and obtaining 2-D barcode information associated with the identified least one 2-D barcode image. The disclosed method and device simplifies operations of 2-D barcodes identification within the retrieved webpage.
