Cursor-Driven Item Property Adjustment in Display Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display apparatuses lack dynamic and intuitive methods to change the properties of items in a list based on their location relative to a cursor, such as size and opacity, which can enhance user interaction and content presentation.
Innovation Solution
An image display method and apparatus that gradually change the properties of items, such as size and opacity, based on the overlapping extent of virtual areas set for the cursor and the items, allowing for dynamic and interactive content presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If properties of items in an item list are changed based on location relative to cursor, then user interaction and content presentation are enhanced, but device complexity increases
Solution Approach 1:
The patent applies local quality by assigning different visual properties (size, opacity, brightness) to different items in the list based on their spatial relationship to the cursor. Items closer to the cursor position have enhanced properties while distant items have reduced properties, creating a gradient effect that guides user attention without requiring complex system-wide changes
Solution Approach 2:
The patent implements dynamics by continuously updating item properties as the cursor moves through the list. The visual characteristics of items dynamically change in response to cursor position, creating an interactive experience where the interface adapts to user movement in real-time
2Illumination intensity
If multiple properties of items are changed simultaneously, then content presentation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes parameter changes by modifying multiple visual parameters of list items simultaneously (size, opacity, brightness) based on a single controlling factor - the distance from the cursor. This coordinated parameter adjustment creates a unified visual effect while simplifying control logic

AI summary
An image display method includes displaying, on a display, an item list that includes items and a cursor that indicates a location of a user input on the display, detecting movement of the user input for moving the cursor; and moving the cursor in response to the detected movement and changing properties of an item among the items according to an overlapping extent of a first virtual area that is set with respect to the cursor and a second virtual area that is set with respect to the item.
