Handwriting Ratio Adjustment for Screen Orientation Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to maintain the accuracy, readability, and aesthetic quality of handwriting inputs when switching from portrait to landscape mode, as they uniformly adjust the ratio of all inputs without considering their type or importance.
Innovation Solution
The electronic device employs an AI model to identify and maintain the width-to-height ratio of specific handwriting input types while adjusting others based on a new ratio, ensuring accurate and readable display even when the screen orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device uniformly adjusts the ratio of all handwriting inputs when switching screen orientation, then the screen ratio change is achieved, but the accuracy and readability of handwriting inputs deteriorate
Solution Approach 1:
The patent segments handwriting inputs into different types (e.g., text-based and drawing-based) and applies different ratio adjustment strategies to each type. Text-based handwriting inputs maintain their original ratio while drawing-based inputs are adjusted to the new screen ratio, resolving the contradiction between achieving screen orientation adaptation and maintaining handwriting accuracy.
Solution Approach 2:
The patent applies local quality by differentiating the treatment of different handwriting input types. Instead of uniform adjustment, the system maintains specific properties (ratio, aspect ratio) for certain input types while allowing changes for others, thereby preserving accuracy and readability for critical inputs while achieving overall screen adaptation.
2Measurement precision
If the electronic device maintains the original ratio of all handwriting inputs during screen orientation change, then the handwriting accuracy is preserved, but the aesthetic quality and adaptability to new screen ratio deteriorate
Solution Approach 1:
The system segments handwriting inputs into categories and applies selective ratio adjustment. Drawing-based inputs that benefit from the new screen ratio are adjusted, while text-based inputs maintain their original ratio to preserve accuracy. This segmented approach allows the system to adapt to new screen ratios without compromising the integrity of critical handwriting data.
Solution Approach 2:
The patent implements local quality by applying different transformation rules to different parts of the handwriting input. Certain input types undergo ratio adjustment to match the new screen orientation, while other input types maintain their original proportions, achieving a balance between adaptability and preservation of input quality.
3Adaptability or versatility
If the electronic device adjusts the ratio of handwriting inputs without considering input type, then the screen orientation change is achieved, but the readability and aesthetic quality of handwriting inputs deteriorate
Solution Approach 1:
The patent segments handwriting inputs into distinct types (text-based and drawing-based) and applies appropriate transformation rules to each. This segmentation ensures that text-based inputs remain readable and drawing-based inputs adapt to the new screen orientation, thereby maintaining ease of operation while achieving screen orientation change.
Solution Approach 2:
The system applies local quality by differentiating the treatment of different input types. Text-based handwriting inputs maintain their original ratio and properties to ensure readability, while drawing-based inputs are adjusted to the new screen ratio. This differentiated approach preserves the quality and readability of handwriting inputs during screen orientation transitions.

AI summary
An electronic device is provided. The electronic device includes a display, at least one processor, and memory storing instructions, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to display, on the display, a first screen in which a height-to-width ratio corresponds to a first ratio, wherein the first screen includes at least one handwriting input of a first type and at least one handwriting input of a second type, identify a command for changing the height-to-width ratio of the first screen from the first ratio to a second ratio, and based on the command, display a second screen obtained by changing the width-to-height ratio of the first screen to the second ratio, wherein the width-to-height ratio of the at least one handwriting input of the first type included in the second screen is maintained such that the width-to-height ratio of the at least one handwriting input of the first type included in the second screen is same as the width-to-height ratio of the at least one handwriting input of the first type included in the first screen, and the width-to-height ratio of the at least one handwriting input of the second type included in the second screen is changed based on the second ratio.
