Dynamic Screen Scaling for Single-Handed Mobile Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with touchscreens are difficult to operate single-handedly due to their large screen size, as existing scaling methods only allow for fixed proportion scaling, which does not accommodate the varying hand spans of users.
Innovation Solution
A method for dynamically scaling down the effective display area of a mobile terminal's screen based on user input, allowing continuous scaling according to a user's requirement, using a combination of single-finger operations and preset correspondences to determine scale-down or scale-up proportions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is made large, then the display area is improved, but the ease of single-handed operation deteriorates
Solution Approach 1:
The patent implements dynamic scaling of the display area through continuous touch operations. The display area can be continuously scaled down from the full screen to a smaller region, and scaled back up, allowing the system to adapt between large display mode and single-handed operation mode based on user needs
Solution Approach 2:
The patent changes the parameter of display area size through touch-based scaling operations. By detecting touch movements and calculating scale ratios, the system dynamically adjusts the effective display area parameter to accommodate different usage scenarios, transforming the fixed large screen into an adjustable display region
2Device complexity
If fixed proportion scaling is used, then the device complexity is reduced, but the adaptability to different user hand spans deteriorates
Solution Approach 1:
The patent replaces fixed proportion scaling with dynamic continuous scaling. The scaling ratio is determined by the user's touch movement distance and direction, allowing the display area to be scaled to any proportion within a range, thereby adapting to different user hand spans without increasing device complexity
Solution Approach 2:
The system provides visual feedback during scaling operations, showing the user the current display area and allowing continuous adjustment. This feedback mechanism enables users to intuitively adjust the display area to match their hand span requirements, achieving adaptability through user interaction rather than complex preset configurations

AI summary
Embodiments of the present invention disclose a method for scaling down an effective display area of a screen, and a mobile terminal, to continuously scale down an effective display area of a screen according to a user's requirement. The method in the embodiments of the present invention includes: displaying, by a mobile terminal, first content; when an obtained first operation satisfies a preset condition, sensing a second operation; determining, according to a preset correspondence, a scale-down proportion corresponding to the second operation; and continuously scaling down an effective display area of a screen of the mobile terminal according to the scale-down proportion, so that the first content is displayed on a scaled-down effective display area.
