Touch Screen Object Rotation and Scaling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device touch screen systems cannot perform nonlinear rotations of objects with a single touch and fail to automatically scale objects to fit the screen size during rotation, limiting user interaction and usability.
Innovation Solution
A system comprising a touch screen interface, a single touch setting module, a single touch driving module, and an image processing module with an object rotating module and an object scaling module, allowing single touch activation of object rotation and scaling to fit the screen, with options for arbitrary rotation angles and directions, and automatic size adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary button is used for rotation, then rotation control is achieved, but nonlinear rotation and arbitrary angle rotation are not possible
Solution Approach 1:
The patent replaces the mechanical rotary button system with a touch-based software control system. The touch screen detects finger position and movement to generate rotation commands, eliminating the need for physical mechanical components while enabling nonlinear and arbitrary angle rotation through software algorithms.
Solution Approach 2:
The rotation system transitions from static rotary button positions to dynamic touch-based control. The rotation angle and speed are determined by the finger's position and movement on the touch screen, allowing continuous adjustment to any angle and enabling both linear and nonlinear rotation modes.
2Adaptability or versatility
If two-finger touch is used for rotation, then rotation is possible, but arbitrary angle rotation and automatic scaling are not achieved
Solution Approach 1:
The system performs automatic scaling and fitting of rotated objects without requiring additional user input. After rotation, the object is automatically scaled to fit the screen boundaries, and the system self-adjusts the view to center the object, eliminating the need for manual scaling operations.
Solution Approach 2:
The touch-based rotation system integrates multiple functions into a single operation: rotation to arbitrary angles, automatic scaling to fit screen, and automatic centering. This multi-functional approach replaces the need for separate controls for each operation.
3Measurement precision
If manual scaling is required during rotation, then precise control is possible, but operation efficiency decreases
Solution Approach 1:
The system automatically scales the rotated object to fit within the screen boundaries and centers it, performing what would traditionally require manual user adjustment. This self-service approach maintains precise fitting control while eliminating the need for additional manual scaling operations.

AI summary
A system for controlling a rotation of an object on a touch screen includes a touch screen interface, a single touch setting module for detecting a single touch action, a single touch driving module for receiving information from the single touch setting module and activating a rotating action on the object, and an image processing module including an object rotating module which rotates the object and an object scaling module which scales the object size to fit with the touch screen interface. A method for controlling a rotation of an object on a touch screen interface includes executing single touch, activating a rotating action, rotating the object, and stopping the rotating action of the object. There is a predetermined time between the activating the rotating action and the executing single touch. When the object executes the rotation action, the object size is scaled to fit with the touch screen interface.
