Display Control Device for Overlapping Windows Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to easily recognize windows displayed on a rear surface when multiple windows overlap on a screen, as the visibility of rear windows is obscured by those on the front surface.
Innovation Solution
A display control device and method that adjusts the two-dimensional location and transparency of overlapping objects based on the user's viewing direction, allowing for clearer distinction between foreground and background windows by changing the horizontal and orthogonal positions of objects and adjusting their transparency levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple windows are displayed overlapping each other on a display screen, then the display space is efficiently utilized, but the visibility of rear windows is obscured by front windows
Solution Approach 1:
The patent applies local quality by adjusting the transparency of specific windows based on their depth position. Front windows maintain higher opacity while rear windows have increased transparency, allowing selective modification of visual properties in different spatial zones to resolve the visibility conflict
Solution Approach 2:
The patent introduces depth information as an additional dimension for organizing overlapping windows. By detecting the viewing direction and calculating depth values for each window, the system creates a three-dimensional spatial arrangement that projects onto the two-dimensional display, enabling rear windows to be visually distinguished through transparency variations
2Loss of information
If windows are displayed with different transparency levels, then rear windows become more visible, but it becomes difficult to distinguish which window is in the front
Solution Approach 1:
The patent implements feedback by detecting the user's viewing direction and using this information to dynamically adjust window transparency. The system continuously monitors which windows are in the front or rear based on the viewing angle and modifies transparency levels accordingly, creating an adaptive display that responds to user interaction
Solution Approach 2:
The patent changes the transparency parameter of windows based on their calculated depth position and the detected viewing direction. By dynamically adjusting this visual parameter according to spatial relationships, the system maintains both rear window visibility and front window identification
3Loss of information
If the two-dimensional location of objects is changed according to viewing direction, then depth information is better represented, but the display layout becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-calculating the depth values for each window based on their position in the overlapping arrangement. This preparation step allows the subsequent transparency adjustment to be performed efficiently without complex real-time calculations during display rendering
