Cursor Shape Deformation for Edge Scrolling Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies lack intuitive and visually engaging methods for edge scrolling, making it difficult for users to navigate and recognize the end of a scrolling list on smart TVs and monitors.
Innovation Solution
The implementation of visual effects such as shape deformation of cursors and scrolling items based on scrolling distance, where the cursor changes shape when approaching the edge of the scrolling area, and items are deformed to indicate the end of the list, providing a more intuitive scrolling experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional scrolling display is used, then the display structure is simple, but users cannot intuitively recognize the end of scrolling list
Solution Approach 1:
The patent applies color changes to scrolling items at the end of the list, causing them to display in a different color (e.g., red) compared to normal items. This visual distinction allows users to intuitively recognize when they have reached the end of the scrolling content without adding complex hardware structures.
Solution Approach 2:
The patent deforms the shape of scrolling items at the end of the list, making them appear curved or distorted compared to the normal rectangular shape of other items. This shape transformation provides a clear visual indicator of the scrolling end while maintaining the same display hardware.
2Ease of operation
If no visual feedback is provided during scrolling, then the display is simple, but user interaction becomes less intuitive
Solution Approach 1:
The patent implements visual feedback mechanisms that provide real-time information to users during scrolling operations. When users scroll and approach or reach the end of the list, the system immediately displays visual cues (color changes, shape deformations) to confirm their position, making the interaction more intuitive and responsive.
Solution Approach 2:
The display changes the color of scrolling items based on their position in the list, particularly highlighting items at the end with distinct colors. This provides immediate visual feedback to users about their scrolling progress and current position without requiring additional hardware complexity.
3Loss of information
If cursor shape remains constant, then the display processing is simple, but users cannot sense their position relative to scrolling edge
Solution Approach 1:
The patent makes the cursor dynamic by changing its shape based on its position relative to the scrolling content. When the cursor approaches or reaches the end of the scrolling list, its shape transforms (e.g., becomes curved or distorted), providing users with real-time position awareness and spatial context during scrolling operations.
Solution Approach 2:
The cursor shape is transformed from a standard geometric form to a curved or distorted shape when it reaches specific positions during scrolling. This curvature effect provides visual feedback about the cursor's position relative to the scrolling content boundaries without requiring complex additional hardware.

AI summary
Provided are a display apparatus (100) and a display method. The display apparatus includes: a display (115) configured to display a cursor (310) based on an input of a control device (200); and a controller (180) configured to control the display to add visual effects to the cursor at an edge of a scrolling area (300) or to the scrolling area based on a scrolling distance of the control device in response to detecting a position of the cursor exiting the scrolling area at the edge of the scrolling area.
