3D Display Illumination Adjustment for Cursor Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In three-dimensional display systems, a cross-mode phenomenon often occurs between the cursor and objects, causing partial overlap and visual frustration due to the display of a three-dimensional cursor model, which hinders effective human-computer interaction.
Innovation Solution
A display method and device that adjust illumination information within a target area based on the position of a mouse and three-dimensional object display areas, including brightness, contrast, and shadow sharpness, to highlight the target position without incorporating cursor data into the three-dimensional object display areas, thereby preventing overlap and enhancing visual clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a three-dimensional cursor model is displayed in the three-dimensional scene, then the user can identify the indicated position, but the cross-mode phenomenon occurs between the cursor and objects causing visual frustration
Solution Approach 1:
The patent extracts the cursor from the three-dimensional object display area by using illumination information to indicate the cursor position. Instead of displaying a three-dimensional cursor model within the 3D scene, the system uses lighting changes in the display area to represent the cursor, thereby removing the harmful cross-mode phenomenon while preserving position indication functionality.
Solution Approach 2:
The patent introduces illumination information as an intermediary between the cursor position and the display. Rather than directly rendering a three-dimensional cursor model, the system uses illumination changes (brightness, contrast, shadow sharpness) as a mediator to convey cursor position information, avoiding direct overlap with three-dimensional objects.
2Loss of information
If illumination information is adjusted within a target area, then the target position is highlighted and visual clarity is improved, but the complexity of the display system increases
Solution Approach 1:
The patent applies local quality by adjusting illumination information specifically within a target area centered on the cursor position. Instead of uniformly changing the entire display, the system locally modifies brightness, contrast, and shadow sharpness only in the relevant area, achieving position highlighting with minimal additional complexity.
Solution Approach 2:
The patent uses partial action by adjusting illumination only within a preset range area (target area) rather than the entire display. This localized approach achieves the highlighting effect with reduced computational complexity compared to processing the whole display area.
