Touch Screen Icon Rearrangement for One-Handed Thumb Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screen portable devices face difficulties in user interface object selection, particularly when the device is held with one hand, as icons located far from the thumb are hard to reach due to the limited reach of the thumb.
Innovation Solution
The method and apparatus automatically rearrange icons on a touch screen to a lopsided display when the device is tilted, facilitating easier selection by shifting icons towards the user's thumb side, utilizing an inclination sensor and controller to detect and respond to device tilt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If icons are arranged in a symmetrical, evenly distributed arrangement on the touch screen, then the display appears balanced and aesthetically pleasing, but icons located across the entire screen furthest from the thumb position become difficult to select when holding the device with one hand
Solution Approach 1:
The icon arrangement transitions from a static symmetrical layout to a dynamic lopsided layout that automatically adapts based on device tilt detection. The system monitors device orientation and reconfigures icon positions in real-time, making the interface flexible and responsive to user interaction context rather than fixed
Solution Approach 2:
The patent applies asymmetry by deliberately creating a lopsided icon arrangement where icons are concentrated on one side of the screen rather than evenly distributed. This asymmetric layout positions icons within the natural reach zone of a thumb, improving accessibility for single-handed operation
2Ease of operation
If the device is tilted from its normal viewing position, then the device can be positioned for better ergonomics or viewing comfort, but the icon arrangement becomes difficult to access with a thumb
Solution Approach 1:
The system performs self-adjustment by automatically detecting device tilt through the sensor and reconfiguring icon positions without requiring manual user input. The interface monitors its own state and adapts autonomously, eliminating the need for users to manually adjust settings
Solution Approach 2:
The patent replaces manual icon rearrangement operations with an automated sensor-based system. Instead of requiring users to physically adjust icon positions or configure settings, the system uses tilt sensors and controllers to automatically detect and respond to device orientation changes
3Adaptability or versatility
If a tilt sensor and automatic rearrangement system are implemented, then icon accessibility is improved when the device is tilted, but the device complexity increases
Solution Approach 1:
The tilt sensor serves multiple functions: it detects device orientation, determines the appropriate icon arrangement mode, and triggers the rearrangement process. This multi-functional approach consolidates several operations into a single sensor mechanism, reducing overall system complexity

AI summary
A method of rearranging a display of at least one icon on a touch screen of a portable electronic device is provided. The method detects if the device has entered a tilted state, and automatically rearranges the display of the at least one icon according to the tilted state. In some implementations, icons are rearranged to be displayed in a lopsided manner when entering the tilted state, thereby facilitating user touch selection of the icons.
