Solution Overview

Problem

Existing text input methods on terminals are inefficient and inaccurate, requiring frequent switching between input methods, which leads to low text input efficiency and user inconvenience.

Innovation Solution

A text editing interface that supports multiple input methods (key, voice, and handwriting) simultaneously, allowing users to switch between them without changing interfaces, enhancing efficiency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single input method is supported on a text editing interface, then the interface design is simple and easy to implement, but text input efficiency is low and users experience inconvenience

Engineering Contradiction:
Improvetext input efficiencyVSAvoidinterface complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple input methods (26-key, nine-grid, voice, handwriting) into a single text editing interface, allowing users to switch between them without changing interfaces. This merging approach resolves the contradiction by maintaining interface simplicity while enabling efficient text input through multiple methods.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The text editing interface is designed to support multiple input methods simultaneously, making it a universal interface that can handle different input scenarios. This multi-functionality improves text input efficiency without requiring separate specialized interfaces for each input method.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If users switch between different input methods by changing text editing interfaces, then each interface can be optimized for its specific input method, but frequent switching reduces text input efficiency

Engineering Contradiction:
Improveinput method switching convenienceVSAvoidtext input efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent merges multiple input methods into one unified text editing interface, eliminating the need for users to switch between different interfaces. This allows convenient input method switching while maintaining high text input efficiency, as the unified interface remains consistent throughout the input process.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If different input methods are supported on the same text editing interface, then text input efficiency and user convenience are improved, but the interface design and implementation become more complex

Engineering Contradiction:
Improvetext input efficiencyVSAvoidinterface design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent designs a universal text editing interface that can accommodate multiple input methods through a unified architecture. This approach manages the complexity by creating a flexible framework that handles different input methods consistently, improving text input efficiency without overwhelming interface design complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A text input method and a terminal are provided. The method includes: displaying a text editing interface when a trigger operation for triggering text input is detected, where the text editing interface includes: input operation areas of at least two input methods and text display areas for displaying text input by using the input methods; and keeping displaying the input operation areas of the at least two input methods on the currently displayed text editing interface when a switching operation for switching from one of the currently used at least two input methods to another input method is detected on the currently displayed text editing interface.
