Gesture-Based User Relationship Setting in Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current social network service methods for setting user relationships in mobile environments are complex and hindered by limitations in input/output interfaces, making it difficult to establish connections intuitively.
Innovation Solution
A method and system that utilize gesture information, such as touch-and-drag gestures, recognized at multiple terminals to determine user relationships based on geographical location, time, and direction, allowing for accurate relationship setting even in environments where terminal motion is uncertain, like in a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input methods (ID entry, search) are used to set user relationships, then relationship setting can be achieved, but the procedure becomes complex and usability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical input methods (keyboard typing, menu selection) with gesture-based interaction. Users perform physical gestures (e.g., drawing shapes, waving patterns) that are directly captured by the device's motion sensors, eliminating the need for complex input sequences and significantly improving ease of operation while reducing procedural complexity
Solution Approach 2:
The system automatically captures and processes gesture data without requiring users to manually input identifiers or navigate complex menus. The gesture recognition system self-service by directly interpreting physical movements as relationship-setting commands, thereby simplifying the user experience and reducing operational complexity
2Measurement precision
If motion sensors are used to detect terminal movement for relationship setting, then gesture recognition is possible, but accuracy deteriorates in environments with uncertain terminal motion (e.g., driving vehicles)
Solution Approach 1:
The patent introduces an intermediary reference frame system that separates user intent from device motion. By establishing a virtual reference frame that accounts for terminal movement, the system mediates between the noisy motion sensor data and the intended gesture, allowing accurate gesture recognition even when the terminal itself is moving unpredictably during driving
Solution Approach 2:
The system performs preliminary calibration and baseline establishment before gesture recognition. It pre-establishes the relationship between sensor readings and actual user movements under various terminal motion conditions, enabling accurate gesture detection even when the terminal is moving during the actual gesture execution

AI summary
A method for setting a relationship between users of a plurality of mobile terminals includes receiving, from a plurality of mobile terminals, information on gestures made on, and recognized at, the plurality of mobile terminals, respectively, with respect to a single user gesture; determining a gesture correlation between the recognized gestures and the single user gesture based on information on the recognized gestures; and determining whether to set a relationship between users of the plurality of mobile terminals based on the gesture correlation.
