Multi-Fingered Grab Gesture Detection for Touch Panel Application Launch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch-controlled devices have limited manipulation variability due to mostly single-fingered or two-fingered gestures, which restricts usage efficiency.
Innovation Solution
A touch-controlled device and method that detects a multi-fingered grab gesture to generate an electronic signal, determining the gesture's position, and outputs a control signal to display an application container on the touch panel, allowing for quick launch of application and functional menus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single-fingered or two-fingered gestures are used for touch-controlled devices, then the device is easy to operate, but the manipulation variability is limited
Solution Approach 1:
The patent changes the parameters of the gesture by introducing multi-fingered grab gestures with varying numbers of fingers (three or more), different grab positions, and different grab orientations. This allows the system to distinguish between multiple types of gestures (e.g., grabbing from left side vs. right side vs. center) and map them to different application containers or functions, thereby increasing manipulation variability while maintaining ease of operation through natural touch interactions
2Adaptability or versatility
If multiple gesture types are introduced to increase manipulation variability, then the versatility improves, but the operation complexity increases
Solution Approach 1:
The patent segments the gesture recognition system into distinct components: detecting the number of fingers involved in the grab gesture, determining the grab position (left side, right side, center, etc.), identifying the grab orientation, and mapping these segmented parameters to specific application containers. This segmentation allows the system to handle multiple gesture types through a structured, modular approach rather than requiring complex holistic pattern recognition, thus improving versatility while controlling operation complexity

AI summary
A method for displaying applications of a touch-controlled device includes the steps of: generating an electronic signal according a gesture applied on a touch panel of the touch-controlled device; generating a detection result according to the electronic signal, wherein the detection result includes a first position of the gesture corresponding to the touch panel; when the detection result indicates that the detected gesture is a multi-fingered grab gesture, starting an application container; and outputting a control signal to the touch panel according to the application container, in order to display the application container at the first position.
