Viewpoint-Responsive Masking Screen for Selective Content Obscuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia content rating systems, such as the MPAA system, are insufficient in preventing exposure to objectionable content like violence, sexual relations, and alcohol use in movies rated as suitable for children, as a significant percentage of G and PG-rated films still contain violent or mature themes.
Innovation Solution
A computerized method and system that determines horizontal viewing angles for multiple viewers and projects a masking screen with specific spatial and size dimensions to obscure objectionable content from a protected viewer's view without blocking it for others, using a processor to calculate optimal masking screen dimensions and locations based on viewer positions and content analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a masking screen is projected to block objectionable content from a child viewer, then the child is protected from harmful content, but the viewing experience of other viewers may be obstructed
Solution Approach 1:
The masking screen is projected only within the specific viewing angle of the protected viewer (first viewer) rather than blocking the entire display. The system calculates precise spatial dimensions and location based on the viewer's position, ensuring that the masking effect is localized to only where needed for protection while leaving other viewing areas unaffected.
2Object-affected harmful factors
If the masking screen covers the entire display area, then all viewers are protected from objectionable content, but viewers who want to see the full content cannot do so
Solution Approach 1:
The masking screen's spatial dimensions and location are precisely calculated to cover only the portion of the display visible to the protected viewer. This localized approach ensures that other viewers whose viewing angles are not covered by the masking screen can see the complete content without obstruction.
3Adaptability or versatility
If content is rated G or PG, then it is considered suitable for children, but objectionable content like violence and sexual relations still appears
Solution Approach 1:
The masking screen acts as an intermediary device between the display content and the protected viewer. It selectively blocks objectionable content (violence, sexual relations, etc.) while allowing appropriate content to pass through, enabling children to view G or PG rated materials without exposure to harmful elements that remain visible to adult viewers.

AI summary
Aspects determine horizontal viewing angles for viewers of a display screen as a function of outer edge visual boundary lines projecting from outer edges of the display screen to different respective viewing locations of the viewers. The aspects determine locations of intersections of outer edge visual boundary lines defining the horizontal viewing angle of a first viewer with the outer edge visual boundary lines defining the horizontal viewing angles of the other viewers, and thereby a masking screen width dimension and spatial location for the first viewer as extending from an intersection location determined on one of the outer edge visual boundary lines defining the first viewer's viewing angle that is closest to the first viewer, to a point on another outer edge visual boundary line defining the first viewer's viewing angle that is outside of the viewing angles of the other viewers.
