Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems fail to account for the viewer's vantage point, resulting in a flat and two-dimensional appearance and allowing unauthorized viewers to access authorized content, lacking security and privacy in metaverse interactions.
Innovation Solution
A predictive display system (PDS) that uses predictive artificial intelligence to display different images based on the viewer's vantage point and bio-authentication, encrypting content for secure access from designated vantage points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional image display systems are used, then the display is simple and easy to implement, but the image appears flat and two-dimensional, lacking depth and realism
Solution Approach 1:
The patent transitions from traditional 2D flat displays to volumetric 3D holographic displays by introducing a temporal dimension through frame sequencing. Multiple 2D frames are displayed in rapid succession at different angular positions around the display axis, creating the perception of a three-dimensional volumetric image through persistence of vision and angular multiplexing.
Solution Approach 2:
The system employs dynamic rotation of the display medium or viewer to present different angular perspectives of the volumetric image. The display rotates through multiple angular positions, presenting different 2D slices or perspectives that collectively form the 3D holographic image, making the display adaptive rather than static.
2Reliability
If images are displayed from a fixed vantage point, then the display system is simple, but unauthorized viewers can access authorized content and security and privacy are compromised
Solution Approach 1:
The patent implements view-dependent rendering where different portions of the volumetric image are selectively visible from different angular positions. Each angular slice or perspective of the 3D image is encoded to be visible only from specific viewing angles, creating localized visibility zones that prevent unauthorized access while maintaining overall image integrity.
Solution Approach 2:
The volumetric image is segmented into multiple angular slices or perspectives, each accessible from specific viewing angles. The display system presents different segments to different viewers based on their positional orientation, ensuring that only authorized viewers at designated angles can access specific content portions.
3Reliability
If different images are displayed for different vantage points, then security and privacy are enhanced, but the device complexity increases due to predictive AI and multiple image processing requirements
Solution Approach 1:
The system pre-computes and stores multiple angular slices or perspectives of the volumetric image before display. These pre-rendered angular segments are prepared in advance and stored in memory, allowing the display system to simply retrieve and present the appropriate pre-computed slice based on the current viewing angle, rather than performing complex real-time rendering.
Solution Approach 2:
The patent creates multiple copies of the base image data, each transformed into different angular perspectives or slices. These copied and transformed versions are stored separately, allowing the display system to switch between pre-prepared copies based on viewer position without requiring complex real-time processing of the original image data.
4Shape
If volumetric 3D holographic images are displayed, then image realism and depth perception are improved, but the energy consumption and computational requirements increase
Solution Approach 1:
The system displays a sequence of 2D frames in rapid periodic succession at different angular positions around the display axis. By refreshing the display at high frequency with periodically rotating angular slices, the system creates the persistence of vision effect that perceives a stable 3D volumetric image, avoiding the need for continuously powered volumetric projection.
Data Source
AI summary
A predictive display system that enables display of different image sets depending on the vantage point of the viewer. The image sets can range from slight variations of the image (e.g., a change in color or a change in viewing angle) to display of an image of a different object. The image sets may be pre-computed or computed on-the-fly based on vantage point data of the viewer in a current session and the viewer’s historical data from previous sessions. Predictive algorithms may be used to determine the viewer’s next likely vantage point(s) in the next milliseconds to seconds.
