Touchscreen Image Rotation and Flipping via Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting video images on touch screen devices require complex operations, such as moving the device body, and only support rotation, limiting user interaction.
Innovation Solution
A method and device that detect finger gestures on a touch screen to determine image operations, allowing for dynamic rotation or flipping of images without moving the device body, supporting multiple image adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image adjustment is performed by moving the touch screen device body, then the image can be rotated, but the operation becomes complicated
Solution Approach 1:
The patent replaces the mechanical operation of moving the device body with a touch gesture-based control system. The processor detects touch gestures on the screen and translates them into image rotation operations, eliminating the need for physical device movement and simplifying the user interaction mechanism.
Solution Approach 2:
The patent introduces a gesture recognition system as an intermediary between the user and the image rotation function. Instead of directly moving the device, users perform gestures on the screen which are then interpreted and converted into rotation commands by the processor, providing a more convenient interface.
2Adaptability or versatility
If image adjustment supports only rotation operation, then the operation is simple, but the functionality is limited
Solution Approach 1:
The patent implements a universal gesture recognition system that can perform multiple image adjustment operations including rotation, flipping, and other transformations. Different gesture patterns (swipe directions, pinch gestures, etc.) are mapped to different image operations, allowing a single interface to provide diverse functionality while maintaining simplicity.

AI summary
A method and a computing device for adjusting the display of an image, where the method includes: obtaining, during a process of playing an image, a finger gesture for processing the image; determining whether the finger gesture is a finger gesture for adjusting the image, the adjusting including rotating or flipping; and adjusting the image according to the finger gesture if the finger gesture is a finger gesture for adjusting the image. After it is determined that a finger gesture for processing an image is a finger gesture for adjusting the image, the image is adjusted according to the finger gesture, and during this process, a touch screen device body does not need to be moved, which is a convenient implementing manner; moreover, the image can be rotated or flipped, supporting different operations on the image.
