Mobile Input Method with Barcode Decoding and OCR Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile applications with barcode-scanning and OCR functions are inconvenient to use, as users must switch between application windows to convert barcode or character patterns into strings for input into other applications.
Innovation Solution
A mobile device with integrated barcode-scanning and OCR functions that allows direct input of captured content into an input field, using a camera module, barcode-decoding module, and control module to activate a trigger element, switching between default and custom input methods, and displaying a preview pane for real-time preview and decoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If barcode-scanning and OCR functions are implemented as separate applications, then the functions can be provided, but user convenience deteriorates due to the need to switch between application windows
Solution Approach 1:
The patent combines barcode-scanning and OCR functions with the system default input method into a unified input method application. This merging allows users to access both barcode recognition and character recognition capabilities within a single interface, eliminating the need to switch between separate application windows while maintaining full functionality of both features
2Adaptability or versatility
If the input method interface includes both virtual keyboard and preview pane, then input options are diversified, but the interface complexity increases
Solution Approach 1:
The patent introduces a preview pane that displays captured barcode or character patterns in a separate dimensional space alongside the virtual keyboard. This spatial arrangement allows the interface to present multiple input options (virtual keyboard for manual typing, preview pane for captured content recognition) without creating a cluttered or complex layout, as each component occupies its own functional zone

AI summary
A mobile device and a switching method of input method thereof are provided. The mobile device includes a general camera module, a specific camera module, a barcode-decoding module, a touch display module, and a control module. The touch display module is configured to display a display frame which has an input field. The control module is configured to activate a trigger element of an image conversion input method in response to an input trigger event of the input field. The control module is configured to control the touch display module to display the input field and a first overlapping window which has a virtual keyboard of a system default input method on the display frame at the same time. The control module is configured to control the touch display module to switch the first overlapping window to a second overlapping window in response to a first trigger event.
