Touch Screen Object Size Adjustment via Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face limitations in screen object size flexibility, as most touch screens only support a single display size, lacking the ability for users to adjust sizes according to their needs, which restricts customization and usability.
Innovation Solution
A method and apparatus that allow screen objects on a touch screen to be adjusted in size by detecting specific touch gestures, such as pinch-in and pinch-out motions, to change the object size based on the relative moving direction and display direction of the touches, enabling users to enlarge or reduce the size of screen objects dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a touch screen is applied to save keyboard area and reduce device size, then the device achieves lightness, slimness, and compactness, but the screen objects lack size adjustment flexibility
Solution Approach 1:
The patent implements dynamic size adjustment of screen objects through touch gestures. The object display module randomly selects display directions for screen objects, and the object size adjusting module enables users to change object sizes dynamically by detecting pinch-in and pinch-out gestures, transforming static display into adaptive, user-controlled sizing.
Solution Approach 2:
The patent changes the size parameter of screen objects based on touch gesture detection. When users perform pinch-in or pinch-out motions, the object size adjusting module modifies the display size parameter accordingly, allowing flexible adjustment from small to large sizes while maintaining the compact device form factor.
2Device complexity
If screen objects support only a single display size, then the display system is simple, but the homescreen lacks flexibility and customization capability
Solution Approach 1:
The system transitions from static single-size display to dynamic multi-size display. The object display module randomly selects display directions and the object size adjusting module enables dynamic size changes through touch gestures, allowing screen objects to adapt their size based on user needs while maintaining relatively simple display hardware.
Solution Approach 2:
The touch screen serves multiple functions: it displays screen objects, detects user touch gestures, and controls object size adjustment. This multi-functional approach allows a single display system to provide both simple display and flexible customization capabilities without requiring separate control mechanisms.

AI summary
A method, an apparatus and a computer-readable medium for adjusting size of screen object adapted to a mobile device having a touch screen are provided. In the method, a display direction is randomly selected for each of at least one screen object to display each screen object on the touch screen, where each screen object has at least one object size capable of being adjusted. Then, the touch screen is used to detect a first touch and a second touch performed on one of the at least one screen object. The object size of the screen object being touched is adjusted according to the display direction thereof and a relative moving direction of the first touch and the second touch.
