Dynamic Display Scaling for One-Handed Mobile Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices with large display screens become cumbersome for single-handed operation, as users struggle to access edges of the screen due to the screen's size, leading to reduced usability and increased likelihood of inadvertent interactions.
Innovation Solution
Incorporating a mode change element adjacent to the display's edge, allowing users to scale down the display screen and reposition it for easier access, enabling the display to be operated with one hand by determining which edge the mode change element is adjacent to based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen size is increased, then the display area is enlarged, but the ease of operation deteriorates due to difficulty in accessing edges
Solution Approach 1:
The display screen size is made dynamically adjustable through a scale change element. When activated, the display screen is scaled down to a smaller size, transforming the static display into a dynamic one that adapts to one-handed operation requirements while maintaining the ability to switch between different display sizes based on user needs

3Adaptability or versatility
If the mode change element is placed at different edges, then the adaptability for different hand usage is improved, but the device complexity increases
Solution Approach 1:
The position of the mode change element is made dynamically configurable. The system can determine which edge of the display area the mode change element should be adjacent to based on user input, allowing the interface to adapt to different one-handed operation patterns without requiring multiple physical buttons or complex mechanical configurations
Solution Approach 2:
The system automatically determines the optimal edge position for the mode change element based on user input, eliminating the need for manual configuration by the user. The device self-adjusts its interface layout to match the user's preferred hand usage pattern

AI summary
A mobile electronic apparatus comprises a display including a display area having a first edge and a second edge, an input unit including a detector, and at least one processor. The display displays a display screen on the display area. The detector detects an operation performed on the display area. The at least one processor places a mode change element adjacent to the first edge or the second edge of the display area, scales down the display screen in response to detection of a first operation performed on the mode change element, and displays the display screen, which is scaled down, as a scaled-down screen on a part of the display area. The at least one processor determines, in response to a user's input to the input unit, which one of the first edge and the second edge is to be adjacent to the mode change element.
