One-Handed Display Interface Control via Dynamic Cursor Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large touch-sensitive displays on electronic devices are difficult to control with one hand, leading to inefficiencies in user operations.
Innovation Solution
An interface control method and system that utilizes detection and response modules to define a one-handed operation area on the display, allowing users to perform control actions through predefined gestures and movements, with adjustable cursors and display areas that accommodate user needs, including zoom-in/zoom-out modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the touch-sensitive display size is increased to provide better visual experience, then the display area and visual quality are improved, but the ease of operation with one hand deteriorates
Solution Approach 1:
The display area is segmented into a full display region and a one-handed operation area. The one-handed operation area is further divided into sub-regions for different functions (e.g., navigation, controls). This segmentation allows the interface to provide both large display area and accessible control areas by separating display functions from interaction functions.
Solution Approach 2:
The interface introduces a virtual dimension through software-based cursor positioning and projected control areas. Instead of physically reducing display size, the system creates a virtual reachable area that can be positioned anywhere on the display through software control, effectively adding a spatial dimension to one-handed operation capability.
2Area of stationary object
If the display size is made larger, then visual experience is improved, but the device complexity increases to accommodate one-handed operation features
Solution Approach 1:
The cursor serves multiple functions: it indicates the current focus area, acts as a virtual pointer for selection, and defines the boundaries of the one-handed operation area. The same software module handles both full-display operations and one-handed mode operations, reducing overall system complexity through multi-functionality.
Solution Approach 2:
The system automatically detects whether the user is operating with one hand or two hands and adjusts the interface configuration accordingly. The cursor position and one-handed operation area are automatically adjusted based on user behavior patterns, eliminating the need for manual configuration and reducing operational complexity.
3Ease of operation
If a one-handed operation area is projected, then ease of operation is improved, but the loss of information increases as some display area is dedicated to controls
Solution Approach 1:
The one-handed operation area and cursor position are dynamic rather than static. The system continuously adjusts the position and size of the one-handed operation area based on the displayed content, ensuring that important information remains visible while maintaining accessible controls. The interface adapts in real-time to balance information display and operational accessibility.
Solution Approach 2:
The system pre-positions the cursor and one-handed operation area in optimal locations before user interaction begins. Frequently used controls are pre-placed within the one-handed operation area, and the cursor is initially positioned to maximize visibility of important display content, reducing the need for users to search or navigate extensively.

AI summary
A method for controlling an interface in an electronic device includes a touch-sensitive display. A first predefined user action is detected, together with a second user action, and the electronic device defines and positions a cursor on the display screen. A first display area which contains soft buttons from a certain part of the display screen (depending on cursor position) is projected within or around the portion of the display within reach of a user's thumb, for one-handed operation. The soft buttons in such first display area can be shrunk or enlarged in size as user requires.
