Handwritten Figure Overlap Resolution in Digital Notebooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens are not suitable for business environments due to difficulties in displaying and managing overlapping handwritten figures, making it hard to read and distinguish between characters and figures.
Innovation Solution
An electronic device with a recognition module, modification module, and display processor that recognizes figures from stroke data, modifies overlapping figures to a standard form, and displays them in a way that enhances visibility, using a digital notebook application program to manage and display handwritten documents effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If overlapping figures are displayed as handwritten on a touch screen, then the handwritten document can be stored and displayed digitally, but the figures become hard to see and distinguish
Solution Approach 1:
The patent segments overlapping figures by detecting their spatial relationships and separating them into distinct display layers. Each figure is individually identified and positioned, allowing the system to render them in a non-overlapping manner while preserving their original handwritten appearance and digital storage benefits.
Solution Approach 2:
The patent changes the spatial parameters of overlapping figures by calculating their relative positions and adjusting their display coordinates. This parameter transformation resolves the overlap issue while maintaining the digital representation, thereby improving visibility without sacrificing digital storage capability.
2Quantity of substance
If multiple stroke data items are stored to represent handwritten figures, then the handwritten document can be digitally preserved, but the figures become difficult to recognize and trace
Solution Approach 1:
The patent performs preliminary figure recognition and spatial relationship analysis on the stored stroke data before display. By pre-processing the stroke data items to identify figure boundaries and overlaps, the system prepares the information in a recognized and traceable format, improving measurement precision while maintaining comprehensive data storage.
Solution Approach 2:
The patent introduces an intermediary processing step that analyzes the relationship between multiple stroke data items and generates figure identification information. This intermediary layer transforms raw stroke data into recognized figure representations, enabling accurate figure tracing while preserving the complete stroke data for digital storage.
3Reliability
If handwritten figures are displayed in their original overlapping form, then the digital notebook can maintain fidelity to the original handwriting, but readability and usability are reduced
Solution Approach 1:
The patent applies local quality modification by selectively adjusting only the overlapping portions of figures while preserving the rest of the handwritten content. The separation and repositioning of overlapping figures is performed locally at the affected areas, maintaining overall handwriting fidelity while improving local readability and usability.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities that allow the display system to adaptively modify figure positions based on overlap detection. The system dynamically repositions figures to eliminate overlaps while preserving the original handwriting characteristics, thereby improving readability without sacrificing fidelity to the original document.

AI summary
According to one embodiment, an electronic device includes a recognition module, a modification module, and a display processor. The recognition module recognizes one or more figures from first stroke data corresponding to a plurality of strokes. The modification module modifies, if a plurality of a first kind of first figures are recognized from the first stroke data, second stroke data corresponding to the plurality of the first kind of the first figures to third stroke data corresponding to the first kind of a second figure. The display processor performs processing of displaying a locus corresponding to the third stroke data on a display.
