Handwritten Data File Coupling via Page Region Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handwritten data drawing/input devices face issues where handwritten data on the same page is inadvertently recorded in multiple files due to stand-by mode transitions, and pages of a paper medium do not have a one-to-one correspondence with files, leading to misunderstandings about the number of pages written on.
Innovation Solution
An information processing device and method that associate pages of a paper medium with files for accumulating handwritten data in a one-to-one correspondence by determining whether to couple files based on identification results of written and unwritten regions on each page, ensuring that data from the same page is not split across multiple files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the position detection device enters stand-by mode to save power, then power consumption is reduced, but handwritten data on the same page is recorded in multiple files
Solution Approach 1:
The system performs preliminary actions by creating a temporary file before entering stand-by mode and then coupling it with the subsequent file after waking up, if they belong to the same page. This preliminary preparation ensures that data integrity is maintained without requiring continuous operation.
Solution Approach 2:
The system uses feedback by analyzing the relationship between handwriting regions in consecutive files to determine whether they belong to the same page. This feedback mechanism allows the system to intelligently decide whether to couple files, preventing data loss while enabling power-saving mode.
2Loss of time
If the file is closed and reopened after stand-by mode, then power is saved during non-operation, but the coordinate data is accumulated in a new file causing page-file correspondence loss
Solution Approach 1:
Before entering stand-by mode, the system creates a temporary file and stores it. After waking up, it checks whether this temporary file and the new file correspond to the same page using handwriting region analysis. If they do, the files are coupled, restoring the one-to-one correspondence between pages and files.
Solution Approach 2:
The temporary file acts as an intermediary that bridges the gap between the file before stand-by mode and the file after stand-by mode. By analyzing the handwriting regions in this intermediary file, the system can determine whether to couple files, thus maintaining reliable page-file correspondence.
3Ease of operation
If the operation button is not pressed to switch files, then operation is simpler, but handwritten data on multiple pages is accumulated in one file
Solution Approach 1:
The system performs self-service by automatically analyzing handwriting regions in consecutive files and coupling them if they belong to the same page. This eliminates the need for manual button pressing while maintaining accurate page separation, as the system autonomously determines whether files should be merged.
Solution Approach 2:
The system uses feedback by continuously analyzing the spatial relationship between handwriting regions in adjacent files. This feedback enables automatic, accurate page separation without requiring user intervention, thus improving ease of operation while maintaining precision.

AI summary
An information processing device includes a storage storing handwritten data generated according to handwritten input to a sheet-like recording medium, in a first file corresponding to a first page and a second file corresponding to a second page, and a controller which determines whether or not to couple (combine) the first and second files based on a first identification result identifying a region of the first page in which the handwritten data has been written or a region of the first page in which the handwritten data has not been written and a second identification result identifying a region of the second page in which the handwritten data has been written or a region of the second page in which the handwritten data has not been written. In response to a determination to couple the first and second files, the controller controls coupling of the first and second files.
