Handheld Device Bar Code Decoding for Mobile Listing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for mobile publication of item listings lack efficient methods for users to access, decode, and utilize item information, such as bar codes, to generate and present listings on hand-held devices, limiting the user experience in buying and selling items.
Innovation Solution
A system and method that includes an item listing subsystem and an item investigation subsystem on hand-held devices, utilizing modules for image access, bar code decoding, item identification, and listing generation, enabling users to capture images, decode bar codes, and generate item listings for posting on a network-based marketplace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users post publication data via a home computer system, then the publication can be created, but the user experience on hand-held devices is limited
Solution Approach 1:
The hand-held device is designed to perform multiple functions: capturing images with the camera, decoding bar codes, accessing item information, generating listings, and communicating with the network-based marketplace. This multi-functionality eliminates the need for separate specialized devices and improves user experience by consolidating operations into a single portable device.
Solution Approach 2:
The system introduces intermediary components including a camera for image capture, a bar code decoder for information extraction, and a network module for communication. These intermediaries enable the hand-held device to interact with the marketplace system without requiring direct complex connections, simplifying the user interface while maintaining functionality.
2Productivity
If bar codes are decoded and item information is accessed on hand-held devices, then listing generation is enabled, but the device must handle multiple processing tasks
Solution Approach 1:
The processing tasks are segmented into distinct functional modules: image capture by the camera, bar code decoding by a dedicated decoder module, item information retrieval through a database or network interface, and listing generation by a software application. This segmentation allows each component to specialize in one task, improving overall efficiency while keeping individual module complexity manageable.
Solution Approach 2:
The system performs preliminary actions by pre-decoding bar codes and pre-fetching item information from databases before the user needs to create a listing. This reduces the processing load during listing generation and improves productivity by having information ready for immediate use.
3Measurement precision
If images are captured and bar codes are decoded to access item information, then accurate item identification is achieved, but the process requires multiple sequential operations
Solution Approach 1:
The system maintains continuous operation by running the bar code decoder and item information access processes concurrently with image capture rather than sequentially. The camera continuously captures images while the decoder processes bar codes and the database queries run in parallel, ensuring that item identification is both accurate and time-efficient.
Solution Approach 2:
The hand-held device performs self-service by automatically capturing images, decoding bar codes, retrieving item information, and generating listings without requiring manual intervention at each step. The system uses its own integrated resources (camera, decoder, database connections) to complete the entire workflow autonomously, reducing processing time while maintaining accuracy.
Data Source
AI summary
Methods and system for mobile publication are described. A captured image may be accessed. A bar code may be decoded from the captured image. An item associated with the bar code may be identified. An item listing of the item may be generated in accordance with the identifying of the item. The item listing may be utilized for posting with a listing manager. One or more item listings for the item may be identified. At least one item listing of the one or more item listings may be provided for presentation in accordance with the searching of the plurality of item listings.
