Solution Overview

Problem

The dense arrangement of text on touchscreen devices makes it inconvenient for users to accurately view and select text, leading to difficulties in operation and user experience.

Innovation Solution

A method and apparatus that enlarge and display text in a first preset area while reducing and displaying text in a second preset area, maintaining the text's initial state by keeping characters in their original row or column positions, allowing for precise user interaction without altering the text's original arrangement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If text is densely arranged on the touchscreen to fit more content, then the information density increases, but the user's ability to accurately view and select text deteriorates

Engineering Contradiction:
Improveinformation densityVSAvoidtext selection accuracy
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent divides the touchscreen display into multiple regions with different magnification levels. The display is segmented into a first region showing enlarged text and a second region showing reduced text, allowing users to view detailed text in the first region while maintaining context from the second region. This segmentation resolves the contradiction by enabling both high information density and accurate text selection through regional differentiation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different display qualities to different regions of the screen. The first preset area displays text with enlarged font size and spacing for precise viewing and selection, while the second preset area displays text with reduced size to maintain overall context. This local quality differentiation allows the system to optimize for both information density and selection accuracy in appropriate regions.

Inventive Principle:
Principle #3Local quality

2Weight of moving object

If the touchscreen size is kept small for portability, then the device portability is improved, but the text viewing and editing convenience deteriorates

Engineering Contradiction:
Improvedevice portabilityVSAvoidtext editing convenience
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a magnification dimension to the two-dimensional touchscreen display. By creating multiple display regions with different magnification levels (enlarged first region and reduced second region), the system effectively adds a third dimension of information presentation. This allows small-screen devices to provide large-text viewing experience without increasing physical device size, resolving the contradiction between portability and text editing convenience.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If text is enlarged in a specific area for better viewing, then the text viewing clarity is improved, but the overall text arrangement and layout are altered

Engineering Contradiction:
Improvetext viewing clarityVSAvoidtext layout stability
Core Design Contradiction:
Measurement precisionVSStability of the object's composition

Solution Approach 1:

The patent implements a dynamic display system where the magnification level and region positioning can be adjusted based on user interaction. The first preset area can be dynamically positioned and sized while the second preset area adapts accordingly. This dynamic adjustment allows the system to maintain flexible layout stability, providing clear text viewing in the enlarged region while preserving the overall text structure through the reduced region.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a copy of the text display in different magnification levels. The first preset area presents an enlarged copy of the text for detailed viewing, while the second preset area maintains a reduced copy showing the overall layout. This copying approach allows users to view text with high clarity in the first region without permanently altering the original text arrangement, as the second region preserves the conventional layout structure.

Inventive Principle:
Principle #26Copying

AI summary

Embodiments of the present invention provide a text processing method, where the method includes: displaying text; acquiring an input of a user; and enlarging and displaying text in a first preset area according to the input, and at the same time, reducing and displaying text in a second preset area, to enable display of the text to stay in an initial state, where to enable display of the text to stay in an initial state means to enable a character in the text to stay displayed at a location in a row and/or a column in which the character in the text is displayed before the enlarging and displaying text in a first preset area and at the same time reducing and displaying text in a second preset area is executed, to resolve a technical problem in the prior art that it is inconvenient for a user to view and select text due to a dense arrangement of the text, thereby bringing beneficial effects of facilitating user viewing and selection, improving operation efficiency of the user, and improving user experience.
