Cursor-Driven Item Property Adjustment in List Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display apparatuses lack the ability to dynamically change the properties of items in an item list based on their spatial relationship with a cursor, leading to inefficient user interaction and potential cognitive fatigue.
Innovation Solution
An image display method and apparatus that continuously change properties such as size, width, height, image, opacity, and location of items in an item list based on their spatial relationship with a cursor, using a controller to detect user input and adjust these properties accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If properties of items in an item list are changed dynamically based on spatial relationship with cursor, then user interaction intuitiveness and selection accuracy are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies local quality by differentiating the visual properties of items based on their spatial relationship with the cursor. Items closer to the cursor position are rendered with different properties (e.g., larger size, higher brightness, different color) compared to items farther away. This creates a gradient of visual emphasis that naturally guides user attention to the intended selection target, improving interaction intuitiveness without requiring complex global changes to the interface.
Solution Approach 2:
The patent implements dynamics by continuously updating item properties as the cursor moves across the display. The visual characteristics of items (size, opacity, position, color) are dynamically adjusted in real-time based on the cursor's current position. This creates a responsive visual feedback system where the interface adapts to user input, making the selection process more intuitive and reducing cognitive load.
2Measurement precision
If multiple item properties (size, width, height, opacity, location) are continuously changed based on cursor position, then visual cues and selection accuracy are improved, but rendering performance and energy consumption increase
Solution Approach 1:
The patent employs parameter changes by systematically modifying multiple visual parameters of items based on their distance from the cursor. Key parameters such as size, opacity, position, and color are adjusted in proportion to the spatial relationship between the item and cursor. This creates a smooth visual transition that enhances selection precision while maintaining a manageable number of parameter adjustments.
Solution Approach 2:
The patent applies partial action by selectively modifying only those item properties that most effectively convey spatial relationship and selection intent. Rather than changing all possible parameters, the system focuses on key visual attributes (such as size and opacity) that provide the most significant visual feedback. This selective approach reduces rendering overhead while maintaining high selection accuracy.
3Loss of information
If cursor movement triggers continuous property changes of adjacent items, then user feedback and interaction quality are improved, but system response time and computational load increase
Solution Approach 1:
The patent implements feedback by continuously updating the visual properties of items in response to cursor movement. As the cursor approaches or moves away from items, the items' visual characteristics change to provide immediate feedback about the spatial relationship. This creates a responsive interaction loop where the system constantly communicates the current state to the user, enhancing feedback clarity and reducing ambiguity in the selection process.
Solution Approach 2:
The patent applies preliminary action by pre-calculating and preparing visual property adjustments for items based on anticipated cursor movement. The system proactively modifies item properties before the user completes the selection action, creating a smooth and responsive visual transition. This reduces the perception of processing delay by having visual updates ready in advance.
