Gesture Shortcut Recognition on Full-Screen Mobile Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional use of virtual keys in mobile terminals becomes limited with the rise of full-screen technologies, necessitating a new method for quickly accessing shortcut functions without being restricted to specific keys.
Innovation Solution
A method and apparatus that recognize and respond to gesture operations as touch inputs to call shortcut functions, allowing users to activate functions like screenshots, voice assistants, or screen-splitting by predefined gestures, such as tapping patterns, rather than relying solely on virtual keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual keys are used for shortcut functions, then the shortcut functions can be accessed, but the method becomes limited with full-screen technologies
Solution Approach 1:
Instead of using physical or virtual keys at the bottom of the screen to access shortcut functions, the patent inverts the approach by using gesture operations on the main display area. The system recognizes gestures (such as specific touch patterns, swipes, or taps) directly on the screen content area to trigger shortcut functions, thereby adapting to full-screen displays while maintaining ease of operation.
Solution Approach 2:
The patent transitions from one-dimensional key pressing (physical or virtual buttons) to two-dimensional gesture operations across the screen surface. By utilizing spatial coordinates, touch duration, and movement patterns in the display area, the system enables shortcut access without requiring dedicated key areas, thus supporting full-screen technology while preserving operational convenience.
2Adaptability or versatility
If traditional virtual keys are used, then shortcut functions are accessible, but the method is restricted to specific key locations
Solution Approach 1:
The patent makes the display area universal by enabling it to serve both as the main content display and as the input area for triggering shortcut functions. Any region of the screen can recognize gesture operations, eliminating the need for dedicated key locations and providing flexible access to shortcut functions across the entire display surface.
Solution Approach 2:
The system dynamically identifies and responds to various gesture operations (taps, swipes, long presses, circular motions) at different screen locations and times. By analyzing touch coordinates, duration, and movement patterns, the system adapts to user intentions in real-time, providing flexible shortcut access without requiring fixed key positions or complex input methods.

AI summary
A method for a device to call a shortcut function, includes: recognizing whether a touch operation is a gesture operation for calling the shortcut function when the touch operation is detected; and calling the shortcut function corresponding to the gesture operation in response to recognizing that the touch operation is the gesture operation for calling the shortcut function.
