Split-Screen Barcode Scanning Interface for Continuous List Updating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for using portable computing devices to scan items and create lists are inefficient due to the need for separate hardware and frequent switching between camera and list views, which increases computing resource usage and power consumption.
Innovation Solution
A portable computing device with a split screen view that simultaneously displays a camera view for scanning and a list view, allowing continuous scanning and updating of the list without frequent view switching, thereby reducing computing resource usage and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate hardware scanning device is used, then scanning capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the camera functionality and item scanning capability into a single integrated system. The portable computing device uses its built-in camera to capture images of items, processes these images to detect computer-readable indicia, and automatically updates the list view without requiring separate hardware scanning devices. This merging eliminates the need for additional scanning hardware while maintaining reliable scanning capability.
Solution Approach 2:
The portable computing device performs multiple functions: it displays the camera view for visual guidance, processes images to detect indicia, updates the list of items, and provides user interaction interfaces. This multi-functional approach eliminates the need for separate dedicated scanning hardware, reducing overall device complexity while maintaining scanning reliability.
2Ease of operation
If switching between camera view and list view is used, then list management is improved, but time loss and operational efficiency deteriorate
Solution Approach 1:
The display is segmented into multiple simultaneous view areas: a camera view area for capturing images and a list view area for displaying managed items. This segmentation allows both functions to operate concurrently without requiring switching between views, eliminating time loss while maintaining effective list management through the divided display layout.
Solution Approach 2:
The patent transitions from sequential view switching (temporal dimension) to simultaneous parallel display (spatial dimension). By arranging camera view and list view side-by-side on the display, the system enables concurrent operation of both functions, eliminating the time required for switching while preserving list management capabilities.
3Productivity
If frequent view switching is used, then list updating is improved, but power consumption and computing resource usage increase
Solution Approach 1:
The system maintains continuous scanning operation within the camera view while simultaneously updating the list view. The camera continuously captures images and the system continuously processes them to detect indicia and update the item list, eliminating interruptions caused by view switching. This continuous operation reduces power consumption and computing resource usage compared to repeated switching cycles.
4Device complexity
If integrated camera scanning is used, then device complexity is reduced, but scanning precision and reliability may deteriorate
Solution Approach 1:
The patent replaces traditional optical scanning mechanisms with image processing-based detection. Instead of using dedicated optical scanners, the system uses the camera to capture images and then employs computational algorithms to detect and interpret computer-readable indicia. This substitution maintains scanning precision while significantly reducing device complexity by eliminating separate scanning hardware.
