Multi-Finger Touch Hand Rotation GUI Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern computing devices with touchscreen capabilities face challenges in dynamically adjusting the graphical user interface (GUI) orientation and virtual keyboard placement based on user hand rotation during multi-finger touch interactions, limiting ergonomic interaction and usability.
Innovation Solution
A system that utilizes multi-finger touch interactions to determine the hand rotation angle and adjusts the GUI orientation and virtual keyboard placement accordingly, incorporating modules for finger touch detection, input gesture determination, hand orientation calculation, and GUI management to provide context-sensitive and ergonomic interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-finger touch interactions are used to detect hand rotation, then ergonomic interaction and usability are improved, but the system complexity increases due to additional gesture recognition requirements
Solution Approach 1:
The patent makes the existing touchscreen gesture recognition system perform multiple functions: it continues to recognize standard gestures (taps, swipes, pinches) while simultaneously detecting hand rotation angles for GUI orientation adjustment. This eliminates the need for separate hand rotation detection hardware or systems, resolving the contradiction by making the existing system multi-functional.
Solution Approach 2:
The system uses its own existing touchscreen input mechanism to detect hand rotation, rather than requiring external sensors or additional input devices. The touchscreen controller itself performs the hand rotation detection by analyzing multi-finger touch patterns, allowing the system to serve its own orientation detection needs without adding external complexity.
2Productivity
If GUI orientation is automatically adjusted based on hand rotation, then user interaction efficiency is improved, but the loss of manual control over display orientation increases
Solution Approach 1:
The patent implements dynamic GUI orientation adjustment that responds to real-time hand rotation detection during multi-finger touch interactions. The GUI orientation changes dynamically based on the detected hand angle, providing adaptive automation that improves efficiency while maintaining user control through the ability to initiate and override orientation changes through continued gesture input.

AI summary
Technologies for manipulating a graphical user interface (GUI) of a display of a computing device include a touch screen of the display capable of receiving user input via physical contact of the user's fingers. The computing device determines whether the user has initiated multi-finger input gesture from which and a hand rotation angle may be determined based on touch points corresponding to the physical contact between the user's fingers and the touch screen. Based on the hand rotation angle, the computing device may take an action on the GUI, such as rotate an orientation of the GUI and/or display a virtual keyboard on the GUI relative to the hand rotation angle and/or the touch points. Other embodiments are described herein and claimed.
