Morphing Touch Screen Layout for Input Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small touch screens on mobile devices pose difficulties in input accuracy due to closely arranged keys and varying user interaction methods, leading to incorrect selections and user frustration.
Innovation Solution
A system that reconfigures the touch screen layout by detecting user interaction and calculating touch areas to resize, reshape, and relocate display elements, allowing for a customized layout based on individual user preferences and interaction patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the touch screen size is reduced to fit mobile devices, then the device portability is improved, but the key size and spacing are reduced making manipulation difficult
Solution Approach 1:
The patent applies dynamics by making the display element layout changeable rather than fixed. The system dynamically reconfigures the positions, sizes, and arrangements of display elements based on user interaction patterns detected over time. This allows the interface to adapt its characteristics to improve ease of operation while maintaining the small device form factor.
Solution Approach 2:
The patent changes multiple parameters of the display elements including their positions, sizes, shapes, and spacing arrangements. By varying these parameters based on detected user interaction data, the system optimizes the interface for individual user preferences and behaviors, resolving the contradiction between small screen size and ease of manipulation.
2Quantity of substance
If keys are arranged in close proximity to maximize screen utilization, then the information density is improved, but the selection accuracy deteriorates due to accidental selections
Solution Approach 1:
The patent applies local quality by creating non-uniform spacing and sizing of display elements based on local user interaction patterns. Frequently touched elements or elements prone to accidental selection are given larger sizes or more spacing around them, while less critical elements maintain compact arrangements. This localized optimization maintains high information density while improving selection accuracy where needed.
Solution Approach 2:
The system performs preliminary action by pre-configuring display element layouts based on anticipated user needs and common interaction patterns. The layout is proactively optimized before users experience selection errors, using detected interaction data to prevent future accidental selections rather than reacting after errors occur.
3Device complexity
If the touch screen layout is fixed to simplify the interface, then the device complexity is reduced, but the adaptability to different user preferences deteriorates
Solution Approach 1:
The patent implements self-service by enabling the interface to automatically reconfigure itself based on detected user interaction patterns. The system monitors how users naturally interact with the device and autonomously adjusts display element layouts without requiring manual user configuration. This maintains interface simplicity while achieving high adaptability to individual user preferences.
Solution Approach 2:
The system uses feedback from detected user interactions to continuously refine and adapt the display layout. By monitoring touch patterns, selection accuracy, and usage behaviors, the system receives feedback that drives automatic reconfiguration of the interface, balancing simplicity with personalization.
Data Source
AI summary
A device displays one or more display elements on a touch screen associated with the device, and detects interaction of a finger, associated with a user of the device, with the touch screen. The device also calculates one or more touch areas associated with the finger based on the detected interaction, and resizes, reshapes, and/or relocates the one or more display elements based on the calculated one or more touch areas.
