Dynamic Sub-Picture Transparency for Cursor Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices with picture-in-picture (PinP) functionality lack sufficient user operability, as users face difficulties in accessing objects behind superimposed sub-pictures, requiring redundant operations to change sub-picture position or size.
Innovation Solution
An image display device with a reproduction controller that adjusts the transparency and position of the sub-picture based on the distance between the sub-picture and the user's cursor, allowing the sub-picture to become transparent when the cursor is close, enhancing user access to underlying objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the sub-picture is superimposed on the main picture to display multiple images simultaneously, then the information display capability is improved, but the user's ability to access objects on the main picture is reduced
Solution Approach 1:
The sub-picture's transparency is dynamically adjusted based on cursor position. When the cursor approaches the sub-picture, the transparency increases automatically, allowing users to see and access objects on the main picture without manually repositioning the sub-picture. This dynamic adaptation resolves the contradiction by maintaining both multi-image display and object accessibility.
Solution Approach 2:
The transparency parameter of the sub-picture is changed in response to cursor position. By modifying this visual parameter dynamically, the system enables users to access main picture objects while the sub-picture remains visible, thus resolving the contradiction between displaying multiple images and maintaining ease of operation.
2Ease of operation
If the user manually changes the position or size of the sub-picture to access objects on the main picture, then the accessibility to main picture objects is improved, but the operational complexity increases
Solution Approach 1:
The sub-picture automatically adjusts its transparency based on cursor position without requiring user intervention. This self-service mechanism eliminates the need for users to manually reposition or resize the sub-picture, reducing operational complexity while maintaining accessibility to main picture objects.
Solution Approach 2:
The system dynamically adjusts sub-picture transparency in response to cursor movement, automatically providing access to main picture objects without requiring users to perform multiple manual operations. This dynamic behavior reduces the number of steps users must take while maintaining ease of operation.
3Ease of operation
If the sub-picture is made transparent when the cursor is close, then the accessibility to main picture objects is improved, but the visibility of the sub-picture is reduced
Solution Approach 1:
The transparency of the sub-picture is adjusted locally based on the cursor's proximity. Only the portion of the sub-picture near the cursor becomes more transparent, while other portions remain visible. This local quality adjustment allows users to access main picture objects when needed while preserving overall sub-picture visibility.
Solution Approach 2:
The sub-picture's transparency is dynamically adjusted based on real-time cursor position. When the cursor is far from the sub-picture, it remains fully visible; when the cursor approaches, the transparency increases locally to allow access to main picture objects. This dynamic adjustment resolves the contradiction between accessibility and visibility.
