Menu Highlight Generation Using Symmetry and Single Source Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for generating and displaying highlights on menu items in user interfaces require significant computational resources and memory, particularly due to the need for multiple source images and complex scaling computations, which can lead to inefficient processing and storage.
Innovation Solution
A display apparatus and method that determines the shape and size of a selected menu item, uses symmetry to select appropriate source images, and generates highlights by magnifying and rotating these images to match the menu item's dimensions, reducing the number of required images and computations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conventional nine-patch method uses separate source images to generate highlight configuration elements at each side of a menu item, then the highlight can be generated with adjustable size and shape, but the amount of computation and memory increases significantly
Solution Approach 1:
The patent applies universality by using a single source image for all four sides of the highlight instead of separate source images for each side. This single image is rotated and scaled to generate highlight configuration elements for different orientations (horizontal, vertical, and diagonal sides), making one image serve multiple functions that previously required four separate images.
Solution Approach 2:
The patent merges the functionality of multiple source images into a single source image. By combining the operations of scaling and rotating a single image, the system generates all necessary highlight configuration elements (for top, bottom, left, right, and diagonal sides) from one unified source, thereby reducing memory usage and computational overhead.
2Ease of operation
If the highlight size increases gradually to provide a smooth animation effect, then the user experience improves, but the time required to generate the highlight increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing rotation angles (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) and their corresponding cosine and sine values in lookup tables. This preprocessing allows the system to quickly retrieve pre-computed values during runtime without performing complex trigonometric calculations, thereby reducing highlight generation time while maintaining smooth animation effects.
3Manufacturing precision
If multiple source images are used to represent different sides of the highlight, then the highlight can be accurately represented for various orientations, but the memory usage increases
Solution Approach 1:
The patent makes a single source image universal by using it to generate all highlight configuration elements for all four sides of the menu item. The same image is rotated and scaled differently to create elements for horizontal sides, vertical sides, and diagonal sides, eliminating the need for separate source images for each orientation while maintaining accurate representation.
Solution Approach 2:
The patent uses copying by creating rotated and scaled versions of the single source image to generate different highlight configuration elements. Instead of storing multiple original source images, the system copies the single source image and applies transformation operations (rotation and scaling) to produce the required elements for different orientations, thereby reducing memory usage while preserving accuracy.
