Split-Screen Barcode Scanner UI for Automatic Product Info Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile device users face inefficiencies when trying to quickly access and compare information for multiple products using barcodes, as they need to interact with multiple controls to switch between scanning different barcodes, hindering the retrieval of product information.
Innovation Solution
A split-screen user interface on mobile devices displays a camera image portion and a product information portion, where the product information automatically updates when a new barcode is captured, eliminating the need for users to select controls and allowing seamless switching between barcodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users interact with multiple controls to switch between scanning different barcodes, then the device can accurately capture and process barcode information, but the operation becomes complex and time-consuming
Solution Approach 1:
The system automatically detects when a new barcode is captured and retrieves the corresponding product information without requiring user intervention. The mobile device performs self-service by monitoring camera input, identifying barcode changes, and automatically updating the product information display, thereby eliminating manual control interactions and reducing time loss.
Solution Approach 2:
The system implements continuous feedback by monitoring the camera feed for barcode detection. When a barcode is detected, the system immediately retrieves and displays the associated product information, creating a real-time feedback loop between barcode capture and information display. This automatic feedback mechanism eliminates the need for users to manually trigger information retrieval.
2Productivity
If the system automatically updates product information when barcode changes, then the information retrieval speed is improved, but the system complexity increases
Solution Approach 1:
The mobile device leverages its existing multi-functional capabilities (camera for photography, web browser for information retrieval, display for output) to perform barcode scanning and product information retrieval. By making these existing components work together in a new integrated manner, the system achieves automatic information updates without requiring dedicated specialized hardware for each function, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system merges multiple functions into a single integrated workflow: the camera captures barcodes, the processor identifies and decodes them, the web browser automatically queries product information, and the display shows the results. This consolidation of functions into one automated process improves productivity while avoiding the complexity of separate independent systems for each function.
3Ease of operation
If users manually select controls to access product information, then the system maintains simple architecture, but the ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically monitoring the camera feed, detecting barcode changes, and retrieving product information without requiring users to navigate menus or press buttons. This eliminates the need for complex user interfaces and control selections, improving ease of operation while keeping the interface simple (essentially just displaying information as it becomes available).
Data Source
AI summary
A computer-implemented method includes receiving a request to scan a barcode and in response, displaying a split screen having a camera image portion and a product information portion. At least part of an image currently being captured by a camera and containing a barcode is displayed in the camera image portion. Product information for a product represented by the barcode is displayed in the product information portion.
