One-Hand Touch Operation for Portable Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-size touch screens on portable electronic devices make it difficult for users to access certain regions with one hand, leading to inconvenient operation.
Innovation Solution
A portable electronic device that detects a touch operation to trigger a one-hand operation mode, defining a dynamic one-hand mode interface display region based on the touch start point position, and displays the operation interface screen scaled down or shifted within this region to enhance usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-size touch screen is used, then the display area is increased, but the ease of operation with one hand deteriorates
Solution Approach 1:
The patent implements a dynamic display region adjustment mechanism that automatically adapts the operable display area based on the detected one-hand operation state. When one-hand operation is detected, the system dynamically modifies the display region to focus on areas accessible by the thumb, making the large touch screen effectively adaptable to different usage scenarios and resolving the contradiction between large display area and one-hand operability
Solution Approach 2:
The patent applies local quality enhancement by identifying and emphasizing specific regions of the touch screen that are most accessible during one-hand operation. Instead of treating the entire large screen uniformly, the system highlights and optimizes the thumb-reachable areas, thereby improving ease of operation in the critical local region while maintaining the overall large display area
2Area of stationary object
If a large-size touch screen is used, then the display area is increased, but the accessibility to certain regions deteriorates
Solution Approach 1:
The system dynamically adjusts the effective display region based on real-time detection of one-hand operation states. By modifying which portions of the large screen are active and responsive during one-hand use, the system ensures that accessible regions remain functional and adaptable, resolving the contradiction between maintaining large display area and ensuring accessibility to necessary regions
3Loss of information
If the operation interface screen is displayed at full size, then the information display capacity is increased, but the ease of operation with one hand deteriorates
Solution Approach 1:
The patent segments the operation interface screen into distinct functional regions: a thumb-operable display region that maintains full information capacity for one-hand use, and other regions that may be adjusted or deactivated. This segmentation allows the system to preserve information display capacity while isolating the one-hand operable portion, thereby resolving the contradiction between information capacity and ease of one-hand operation
Solution Approach 2:
The system dynamically adjusts the display configuration based on the detected operation mode. When one-hand operation is detected, the interface automatically reconfigures to optimize the thumb-reachable region while preserving essential information, thus maintaining information display capacity while improving ease of operation
Data Source
AI summary
A portable electronic device and a one-hand touch operation method thereof are disclosed. A touch operation performed on a touch screen is detected through the touch screen. A touch operation for triggering a one-hand operation mode on the touch screen is detected. A one-hand mode interface display region is defined on the touch screen according to a touch start point position of the touch operation. An operation interface screen that is scaled down or shifted is displayed within the one-hand mode interface display region.
