Arc Menu Index Layout for Touchscreen Thumb Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal menu systems, particularly on touch-screen devices, are inconvenient for users as they require thumb movements that do not align with human engineering, leading to inaccurate operations due to the need for vertical or horizontal gestures.
Innovation Solution
A method and apparatus for displaying an arc menu index, where index characters are arranged along an arc border line, allowing users to operate with their thumb-index finger webspace as the circle center and radius, improving positioning accuracy and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a vertical or horizontal bar menu is used on a touch-screen mobile terminal, then the menu distribution is intuitive and clear, but the user operation convenience deteriorates because the thumb cannot flexibly move and easily clicks a non-target character
Solution Approach 1:
The patent transforms the traditional linear menu structure into a circular arc menu layout. The menu items are arranged along a circular arc path, allowing the user's thumb to naturally follow the curved trajectory during operation. This curvature adaptation matches the natural movement pattern of the thumb, significantly improving operation convenience while maintaining menu item distinguishability and selection accuracy
2Loss of information
If a vertical or horizontal bar menu is used on a touch-screen mobile terminal, then the menu distribution is intuitive and clear, but the positioning accuracy deteriorates due to the need for vertical or horizontal gestures that do not satisfy human engineering
Solution Approach 1:
The circular arc menu layout enables the thumb to move along a curved path that better matches natural finger movement patterns. This curved trajectory provides more precise control and positioning accuracy compared to linear vertical or horizontal gestures, as the thumb can more easily distinguish and target specific menu items along the arc without the limitations of straight-line movement constraints
