Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersive video display technologies, such as VR headsets, cause discomfort and nausea due to the virtual reality illusion, and there is a need for a headset-free method to deliver three-dimensional imagery.
Innovation Solution
A multi-screen, panoramic projection system using a scrim and rear projection screen with strategically positioned projectors to create a three-dimensional image illusion, without the need for headsets, by projecting image portions from different angles onto a reflective scrim and rear screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VR headsets are used to deliver three-dimensional imagery, then immersion is improved, but user comfort deteriorates due to headaches, eye strain, dizziness, and nausea
Solution Approach 1:
The patent introduces a scrim (a semi-transparent screen) as an intermediary between the projection system and the audience. Multiple projectors project images onto the scrim from different angles and positions, creating a three-dimensional holographic effect without requiring headsets. This mediator allows the system to achieve immersion through optical illusions while avoiding the harmful effects of VR headsets.
Solution Approach 2:
The patent transitions from two-dimensional flat screens to three-dimensional holographic imaging by using multiple projectors positioned at different locations (front, rear, left, right) and angles. These projectors cast images onto the scrim from various dimensions, creating a volumetric visual experience that eliminates the need for headset-based virtual reality.
2Illumination intensity
If multiple projectors are used to create three-dimensional imagery on scrim, then image quality and immersion are improved, but system complexity increases
Solution Approach 1:
The patent divides the projection system into multiple independent projectors, each responsible for projecting specific portions of the three-dimensional image onto different areas of the scrim from different angles. This segmentation allows each projector to be optimized for its specific function while collectively creating the complete holographic image, managing complexity through modular design.
Solution Approach 2:
The scrim serves multiple functions simultaneously: it acts as a projection surface for multiple projectors, provides the reflective/transparent medium necessary for holographic imaging, and creates the visual illusion of three-dimensional space. This multi-functionality reduces the need for additional specialized components, managing system complexity while maintaining image quality.
3Shape
If projectors are positioned to project from different angles onto scrim, then three-dimensional effect is improved, but projector visibility to audience increases
Solution Approach 1:
The patent positions projectors in specific locations around the venue (front, rear, left, right) and angles them to project onto specific portions of the scrim. Each projector is strategically placed to contribute to the three-dimensional effect while remaining obscured from the audience's direct line of sight. The scrim's transparency and reflectivity properties are optimized for these specific projection angles, allowing the projectors to be hidden while maintaining image quality.

AI summary
The present invention provides a multi-media, multi-screen, and panoramic projection system (“Holotheater”) that presents three-dimensional, lifelike holographic imagery. The elements of the Holotheater are capable of being integrated into existing venues. The Holotheater comprises a scrim, a rear screen positioned behind the scrim, and an assortment of projectors. Each projector projects a portion of an immersive experience which, when displayed on the scrim and rear screen, appears three-dimensional to an audience without requiring headsets. In some embodiments, additional side screens may be used with corresponding projectors to create a vivid panoramic presentation.
