Touch Input Identification for Immediate Gesture Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld terminal devices with touch screens face challenges in quickly identifying user gesture operations, leading to delayed responses and incomplete execution of user inputs.
Innovation Solution
An input identification method and apparatus that analyze touch tracks to identify first and second partial tracks satisfying preset conditions, allowing for immediate execution of corresponding commands and continuous responses without waiting for gesture completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system waits for complete gesture recognition before executing commands, then gesture identification accuracy is improved, but response speed deteriorates
Solution Approach 1:
The system performs preliminary gesture recognition and identification during the gesture collection phase, rather than waiting for complete gesture execution. The controller continuously monitors touch track parameters and pre-identifies gesture patterns, enabling command preparation before the gesture fully completes, thus reducing response delay while maintaining accuracy
Solution Approach 2:
The gesture recognition process is segmented into multiple stages: touch track collection, partial gesture identification, command generation, and execution. By dividing the continuous gesture into segments and processing each segment progressively, the system can initiate command execution based on partial track information without waiting for the complete gesture, balancing accuracy and speed
2Reliability
If the system requires complete gesture completion before response, then operation reliability is improved, but user convenience deteriorates
Solution Approach 1:
The system provides continuous feedback during gesture execution by monitoring touch track parameters in real-time. The controller gives feedback signals when partial gestures are recognized, allowing users to know their input is being processed without waiting for complete gesture completion. This maintains reliability through continuous monitoring while improving convenience through immediate system response
Solution Approach 2:
The gesture recognition system dynamically adjusts its recognition threshold and processing speed based on the current touch track state. During active gesture collection, the system dynamically evaluates partial tracks against preset conditions and adjusts command generation timing accordingly, enabling flexible response that balances reliability and user convenience based on real-time gesture progress

AI summary
An input apparatus having a touch module and an input identification method applied to the apparatus are described. The method includes during the collection of a touch track on the touch module, when a first partial track of the touch track satisfies a first preset condition, a first command corresponding to the first partial track is obtained; the first command is executed; and during the collection of the touch track, when a second partial track following the first partial track satisfies a second preset condition, a second command corresponding to the second partial track is obtained; and the second command is executed. The method and apparatus can quickly identify a gesture operation of a user on the touch screen, and can continue to perform the corresponding operation after the identification of the gesture operation of the user and before the completion of the gesture operation.
