Dynamic Screen Size Adjustment for One-Handed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in controlling large display regions on electronic devices with touch screens, as the increased size makes it inconvenient to manage information with one hand, especially when a separate input device like a keypad is integrated into the display area.
Innovation Solution
The electronic device adjusts its screen size based on touch input in a designated reference region, allowing users to convert into a screen adjustment mode where the screen size is changed according to the movement distance and direction of the touch input, and sets scale factors corresponding to hand size, enabling easier control of displayed information with one hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display region size is increased to enhance space utilization, then the display area is enlarged, but the ease of operation deteriorates as users have difficulty controlling all information with one hand
Solution Approach 1:
The patent applies dynamics by making the display region size adjustable rather than fixed. The display region can be dynamically enlarged or reduced based on user input, allowing the system to adapt between full-screen mode for maximum display area and reduced mode for easier one-handed control. This resolves the contradiction by enabling the display area to change state according to operational needs.
Solution Approach 2:
The patent changes the parameter of display region size from a static value to a variable that can be adjusted. By receiving user input and modifying the display region size parameter, the system can switch between different display modes (full-screen and reduced), thereby resolving the contradiction between having a large display area and maintaining ease of operation.
2Ease of operation
If the screen size is reduced to improve ease of operation with one hand, then controllability is enhanced, but the area of stationary object deteriorates
Solution Approach 1:
The display region is made dynamic and adjustable. When ease of operation is prioritized, the display region can be reduced to a size suitable for one-handed control. When display area is prioritized, the full-screen mode can be activated. This dynamic adjustment resolves the contradiction by allowing the system to adapt to different operational requirements.
Solution Approach 2:
The display system serves multiple functions: it can operate in full-screen mode to maximize display area and in reduced mode to maximize ease of operation. By making the display region adjustable, the system becomes universal, capable of adapting to both scenarios where large display area is needed and where ease of one-handed control is prioritized.

AI summary
Various embodiments of the present invention relate to an apparatus and method for adjusting a screen size in an electronic device. The electronic device comprises a touch screen and a processor, wherein the processor may perform control so as to: detect a touch input from a reference area set in at least a partial area of the touch screen; when it is detected that the touch input moves, activate a screen adjustment mode on the basis of a movement range of the touch input; when the touch input is maintained, adjust a screen size of the touch screen on the basis of the movement distance of the touch input; and when the touch input is released, set, as a screen size in the screen adjustment mode, the screen size at the time when the touch input is released. Other embodiments may also be possible.
