Touchscreen Icon Layout Adaptation for Two-Hand Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices with large touchscreens face difficulties in accessing icons located far from their thumb's reach when operating with one hand, leading to potential device drops due to the need to use both hands without time to preset a user preference for two-hand mode.
Innovation Solution
A method and apparatus that detect the number and coordinates of finger contacts on a touchscreen to determine if the user intends to use two hands, automatically adjusting the icon display layout to facilitate access, including the option to set a two-hand mode dynamically based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates a portable electronic device with one hand, then the operation is convenient and quick, but the user cannot reach icons located far from the thumb location on the touchscreen
Solution Approach 1:
The system dynamically adjusts the touchscreen icon layout based on detected contact points. When multiple contact points are detected indicating two-hand use, the interface automatically reconfigures to display icons in a two-hand optimized arrangement, allowing users to access all icons comfortably with both hands without manual reconfiguration
2Adaptability or versatility
If a user sets a two-hand mode preference in advance, then the icon layout can be optimized for two-hand operation, but the user cannot adapt quickly when temporarily needing two hands without time to preset
Solution Approach 1:
The system automatically detects when a user is using two hands by monitoring contact points on the touchscreen and self-adjusts the icon layout accordingly. This eliminates the need for users to manually preset preferences, allowing immediate adaptation to two-hand operation when needed without any setup time
Solution Approach 2:
The system continuously monitors touchscreen contact points and uses this feedback to determine hand usage mode. Based on the detected contact pattern, the system automatically switches between one-hand and two-hand optimized layouts, enabling real-time adaptation to user needs
3Productivity
If a user uses one hand to hold the device, then quick operation is possible, but the device may be dropped when two hands are needed
Solution Approach 1:
The system provides dynamic layout adjustment that allows users to quickly switch between one-hand and two-hand operation modes. When two hands are detected, the interface automatically reconfigures to support stable two-hand holding and operation, eliminating the need to manually adjust settings and reducing the risk of dropping the device

AI summary
A method for setting a two hand mode to operate a touchscreen includes: receiving, via the touchscreen, at least one point of contact on the touchscreen generated by one or more fingers of a user, the touchscreen including a plurality of icons; detecting, by at least one processing device, a total number of the points of contact on the touchscreen and respective coordinates of the points of contact; determining, based on the total number of the points of contact and the respective coordinates of the points of contact, whether the user intends to use two hands to operate the touchscreen; and controlling the touchscreen to display the plurality of icons according to a result of the determining.
