Pseudo-volumetric Display for Collaborative Group Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual display systems fail to facilitate group interaction and collaboration among multiple simultaneous viewers, as they often immerse attention outwardly, preventing eye contact and shared focus.
Innovation Solution
A pseudo-volumetric display apparatus with an inwardly facing cylindrical image display surface and an upwardly facing planar image display surface, synchronized by generators and a controller, allowing simultaneous viewing and interaction from outside, enabling a shared, interactive visualization platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large flat screens or panoramic screens are used to display visual information to multiple viewers, then the visual information can be shared among multiple viewers, but the viewers' attention is directed outwardly and diffused, preventing group interaction and collaboration
Solution Approach 1:
The patent transitions from traditional 2D flat screens to a 3D volumetric display structure with multiple surfaces (front, back, top, bottom) that enclose a volume. This dimensional change allows viewers to gather around the display from multiple angles while maintaining eye contact with each other, solving the contradiction between serving multiple viewers and enabling group interaction.
Solution Approach 2:
Instead of having viewers face outward toward a large screen as in traditional systems, the patent inverts the arrangement by having viewers gather inward around a compact volumetric display. This inversion allows viewers to maintain eye contact with each other while still accessing the visual information displayed on the volumetric structure.
2Adaptability or versatility
If 360 degree LED video displays or ring projection screens are used to provide panoramic imagery, then visual information can be presented to multiple viewers, but the screen blocks eye contact between different viewers and directs attention away from other viewers
Solution Approach 1:
The patent divides the display into multiple segmented surfaces (front surface, back surface, top surface, bottom surface) that collectively form a volumetric structure. Each surface can display independent visual information, providing panoramic viewing capabilities while maintaining a compact form factor that doesn't block viewer interaction.
Solution Approach 2:
The patent creates a nested volumetric structure where multiple display surfaces are arranged concentrically to enclose a volume. Viewers gather around the exterior of this nested structure, allowing them to view panoramic content on different surfaces while maintaining eye contact with each other, unlike traditional 360 degree displays that require viewers to face outward.
3Illumination intensity
If large scale panoramic screens are used to immerse viewers in visual imagery, then viewers are immersed in the visual content, but the setup is expensive and time consuming
Solution Approach 1:
The patent achieves visual immersion not through a single large-scale screen but through a compact volumetric structure with multiple display surfaces. This dimensional approach concentrates the immersive experience into a smaller footprint, reducing setup complexity and cost while maintaining the immersion effect through multi-surface display.
Solution Approach 2:
The patent combines multiple display surfaces (front, back, top, bottom) into a single integrated volumetric display structure. This merging of multiple surfaces into one cohesive unit provides immersive panoramic viewing while simplifying the overall system setup compared to traditional large-scale panoramic screens.

AI summary
A pseudo-volumetric display apparatus includes a first inwardly facing image display surface having a continuous geometry, with an open upper end, for presenting an interior panoramic image, and a second upwardly facing image display surface, located at a lower end of the first image display surface, for presenting a second image. The images may be generated optically or electronically. The second image is correlated and synchronized to the first image, and the first image display surface is sized and positioned to facilitate simultaneous viewing of both images from outside of the first surface via the open upper end. The same or coupled information may be simultaneously presented as a continuous Cartesian representation on the first image display surface and as a polar representation on the second image display surface, and content of one representation may be synchronized in accordance with a selected position in the other representation.
