Touch Screen Magnifier Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen magnification methods require frequent clicking on a magnifier icon and fixed shape magnifiers, leading to inconvenient user operations and poor user experience.
Innovation Solution
A method that determines a sliding track on a touch screen and judges whether it satisfies a preset pattern, invoking a magnifier corresponding to the pattern, allowing users to sketch patterns to invoke magnifiers of various shapes for zooming images with special shapes, thereby simplifying the magnification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mouse is used to click a magnifier function icon to magnify an image, then the magnifier function can be invoked, but user operation becomes inconvenient due to frequent clicking
Solution Approach 1:
The system pre-recognizes gesture patterns (such as circular motions or specific swipe patterns) that users can perform to directly invoke magnifiers. Instead of requiring users to click through menus and icons, the gesture recognition system is prepared in advance to detect and respond to these preliminary gestures, directly triggering the magnifier function without intermediate steps.
Solution Approach 2:
The patent replaces the mechanical clicking action (mouse clicks on icons) with a gesture-based touch interface. Users draw gestures directly on the screen, and the system recognizes these gestures to invoke magnifiers. This substitution eliminates the need for physical clicking while maintaining the magnification function, improving ease of operation and reducing time loss.
2Adaptability or versatility
If a fixed shape magnifier is used, then the magnifier function is simple to implement, but user experience deteriorates due to inability to zoom images with special shapes
Solution Approach 1:
The magnifier system transitions from static fixed shapes to dynamic gesture-based shapes. Users can draw arbitrary gestures on the screen, and the system dynamically creates magnifiers that adapt to the drawn gesture shapes. This allows the magnifier to take any shape the user needs, improving adaptability while the system handles the complexity of shape recognition and generation automatically.
Solution Approach 2:
The system changes the parameters of the magnifier from fixed geometric properties to variable properties determined by user gestures. The shape, size, and position of the magnifier are no longer fixed but are parameters that can be changed based on the gesture recognition results, enabling the magnifier to adapt to different image shapes and user needs.
