Gesture-Based Note Search System for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional text-based input methods for labeling note items in mobile terminals are inconvenient and lack privacy, as they can be easily guessed by others, making it difficult to search note items quickly and securely.
Innovation Solution
A method and system that utilize custom gestures as markers for note items, where the gesture is detected and saved, allowing for quick and secure searching by matching input gestures with corresponding note items, incorporating factors like handwritten speed, pressure, and pattern similarity for accurate matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional text input is used for labeling note items, then users can classify and search note items, but the operation requires multiple steps and privacy protection is insufficient
Solution Approach 1:
The patent replaces the mechanical text input system with a gesture-based input system. Users draw gestures on the touchscreen to label and search note items, eliminating the need for keyboard typing and multiple menu navigation steps. This substitution maintains the classification functionality while improving both operational ease and privacy protection.
Solution Approach 2:
The patent extracts the essential classification function from text input and implements it through gesture recognition. By separating the labeling function from text entry and using visual gestures instead, the system achieves faster operation and better privacy protection while maintaining the core note organization capability.
2Adaptability or versatility
If text labels are used for note items, then note items can be organized by category, but the labels can be easily guessed by others
Solution Approach 1:
The patent replaces predictable text labels with non-verbal gesture patterns. Users create unique gestures that are difficult to guess or intercept, while the system maintains the ability to classify and organize notes by these gesture-based labels. The gesture recognition system preserves adaptability for note organization while significantly improving privacy security.
3Productivity
If custom gestures are used as markers for note items, then searching becomes quick and secretive, but the system requires gesture detection and matching capabilities
Solution Approach 1:
The patent implements self-service through automatic gesture recognition and note retrieval. When a user draws a gesture, the system automatically detects the pattern, matches it with stored gestures, and retrieves the corresponding note without requiring manual selection or additional input. This automation achieves fast search productivity while managing system complexity through efficient pattern matching algorithms.
Solution Approach 2:
The patent creates a universal gesture recognition system that handles multiple functions: labeling new notes, searching existing notes, and organizing note categories. By using a single gesture-based interface for all these operations, the system achieves high productivity across different tasks while consolidating functionality rather than adding separate mechanisms for each function.

AI summary
A method and a system of searching note items by mobile terminals. The method includes the following steps: when marking a note item, detecting a gesture input from a touchscreen or choosing a gesture which has been input, and saving the gesture and the corresponding relation between the gesture and the note item into a memory; when a note item needs to be searched, detecting a gesture input from the touchscreen, and according to the input gesture, searching a matching gesture from the gestures saved in said memory, if the matching gesture is found, then displaying each note item corresponding to the matching gesture according to said corresponding relation. A custom gesture is created as a marker for a note item and the matching note item is displayed according to the input gesture when searching the note item.
