Solution Overview

Problem

Users of mobile terminals face inconvenience in executing functions due to the need to navigate through multiple touch menus on narrow screens, making it difficult to input commands efficiently.

Innovation Solution

A method and apparatus that detect and recognize writing gestures on a touchscreen to execute functions by comparing the input gesture with preset gestures, allowing direct execution of target item functions without the need for extensive menu navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users navigate through multiple touch menus on a narrow touchscreen to execute functions, then the terminal provides comprehensive function access, but the operation complexity and time required increase significantly

Engineering Contradiction:
Improvefunction execution convenienceVSAvoidtime for menu navigation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by detecting and analyzing the writing gesture pattern before executing the target function. The gesture recognition system pre-processes the input by comparing the detected gesture trajectory against stored gesture templates, enabling direct function execution without requiring users to navigate through multiple menu levels. This preliminary gesture analysis replaces the traditional multi-step menu navigation sequence.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent substitutes the mechanical menu navigation system (sequential touching of menu items) with a gesture recognition system that interprets writing patterns. Instead of requiring physical navigation through hierarchical menus, the system uses software-based gesture pattern matching to directly map handwritten gestures to function execution commands, reducing operational steps and time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the touchscreen displays multiple touch menus for command input, then comprehensive control is available, but the narrow screen makes it difficult to display all options and increases input complexity

Engineering Contradiction:
Improvecommand input flexibilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The writing gesture recognition system provides universality by enabling a single input mechanism (writing gesture) to execute multiple different functions. Instead of requiring separate menu structures for different operations, the system uses a universal gesture-based interface where different gesture patterns (e.g., different strokes, directions, or shapes) map to different functions, reducing the number of displayed menus while maintaining comprehensive control capabilities.

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

Solution Approach 2:

The system extracts the essential control function from complex menu structures and implements it through simplified gesture recognition. By taking out the core command execution capability from the multi-layered menu system and representing it through direct gesture-to-function mapping, the interface complexity is reduced while preserving adaptability across multiple functions.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If traditional touch menu navigation is used, then precise function selection is achieved, but the number of required input commands increases

Engineering Contradiction:
Improvefunction selection accuracyVSAvoidcommand input efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary gesture pattern matching and recognition before function execution, ensuring precise function selection through automated gesture-template comparison. This preliminary recognition process eliminates the need for multiple confirmatory menu selections, maintaining measurement precision while reducing the number of required input commands from many menu taps to a single gesture input.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent substitutes the mechanical sequential selection process (multiple menu taps and confirmations) with an automated gesture recognition system. The system uses pattern matching algorithms to automatically identify the intended function from the gesture trajectory, replacing the manual step-by-step menu navigation with a single intuitive writing gesture that achieves the same precise function selection with higher productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Methods and apparatus are provided for executing a function of a mobile terminal by recognizing a writing gesture. The writing gesture that is inputted on a touchscreen of the mobile terminal is detected. At least one target item to which the writing gesture applies is determined. A preset writing gesture of the at least one target item is compared with the detected writing gesture to determine whether the preset writing gesture is at least similar to the detected writing gesture. An execution command corresponding to the preset writing gesture is extracted, when it is determined that the detected writing gesture is at least similar to the preset writing gesture. The function of the at least one target item is executed by the execution command.
