Electronic Device Handwritten Locus Display Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an increasing demand to easily view and store handwritten loci added as comments on the display screen of electronic devices, such as tablets and smartphones, which current technologies do not effectively address.
Innovation Solution
An electronic device with a touch screen display that records and manages handwritten strokes as time-series information, allowing users to input and display handwritten documents, and includes features for editing and managing note files with associated data like date, time, and tags, enabling intuitive interaction and organization of handwritten content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If handwritten loci are added to the display screen for commenting, then the information content and annotation capability are improved, but the readability and clarity of the original content deteriorate
Solution Approach 1:
The patent applies color changes by displaying the handwritten locus in a different color (red) than the original display content, allowing the annotation to be visually distinguished from the original content while maintaining readability of both elements
Solution Approach 2:
The patent resolves the contradiction by transitioning from a 2D plane conflict to a 3D layered structure, where the handwritten locus is displayed on a layer above the original content, enabling both elements to coexist without mutual interference
2Ease of operation
If the display content is magnified to make handwritten locus more visible, then the visibility of handwritten input is improved, but the overall screen layout and other displayed information are affected
Solution Approach 1:
The patent applies dimensionality change by creating a magnified 3D projection of the handwritten locus that extends above the original screen layout, allowing enhanced visibility without disrupting the underlying screen arrangement or requiring redesign of the overall layout
3Manufacturing precision
If the handwritten locus is displayed in the original gradation, then the fidelity of the handwritten content is maintained, but the visibility and contrast of the locus deteriorate
Solution Approach 1:
The patent applies color changes by rendering the handwritten locus in red color with enhanced brightness, which maintains the visual characteristics and fidelity of the handwritten content while significantly improving its visibility and contrast against the background

AI summary
According to an embodiment, an electronic device comprises a display control module and a drawing module. The display control module is able to display content by one of a first image with a first gradation and a second image with a second gradation lower than the first gradation. The content is displayed by an application. The drawing module is able to draw a locus input by handwriting on a screen. The display control module displays the content by the second image when the locus is drawn by the drawing module.
