Multi-Surface Projection Layout for Immersive 3D Theater Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection systems in theaters provide limited immersion due to the use of two-dimensional screens, which restricts the three-dimensional effect and viewer engagement, even with advanced 3D technologies like IMAX.
Innovation Solution
A multi-projection system with non-parallel projection surfaces on multiple sides, including front, left/right, and top/bottom, using projectors and display means like LED or LCD, to create immersive three-dimensional images by projecting images from various angles and surfaces, adjusting for surface types, colors, materials, and distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional screens are used for projection, then the system structure remains simple, but the degree of immersion and three-dimensional effect deteriorates
Solution Approach 1:
The patent transitions from traditional two-dimensional flat screens to three-dimensional spatial projection surfaces. Multiple projection surfaces are arranged in three-dimensional space at different positions and angles, creating a volumetric projection environment that enhances immersion while managing system complexity through structured spatial configuration.
Solution Approach 2:
The projection system is divided into multiple independent projection surfaces rather than using a single large screen. Each projection surface can be independently positioned and configured in three-dimensional space, allowing the system to achieve high immersion through spatial distribution while maintaining manageable complexity through modular segmentation.
2Adaptability or versatility
If multiple projection surfaces are arranged in three-dimensional space, then the degree of immersion improves, but the system complexity increases
Solution Approach 1:
The control device performs multiple functions: it generates projection images, corrects geometric distortions, adjusts for surface characteristics, and coordinates multiple projectors. This multi-functionality consolidates complexity into a single control unit, allowing multiple projection surfaces to work together seamlessly without proportionally increasing overall system complexity.
Solution Approach 2:
The system incorporates image correction mechanisms that account for the specific characteristics of each projection surface. The control device adjusts projection parameters based on surface geometry, material properties, and positioning, creating a feedback loop that optimizes the projection system's performance and manages complexity through adaptive control.
3Adaptability or versatility
If images are projected onto different types of surfaces, then the immersion effect improves, but the need for image correction increases complexity
Solution Approach 1:
The control device adjusts projection parameters such as geometric transformation, brightness, and color balance based on the specific characteristics of each projection surface. By dynamically changing these parameters, the system accommodates diverse surface types (screens, wall surfaces, transparent surfaces) without requiring separate correction systems for each surface type.
Solution Approach 2:
A single control device handles image correction for all types of projection surfaces through programmable algorithms. This universal correction capability manages the complexity of adapting to different surface types by consolidating correction functions into one adaptable system rather than requiring dedicated correction mechanisms for each surface type.

AI summary
A multi-projection system having a plurality of projection surfaces onto which images are projected is provided, where the plurality of projection surfaces are disposed on two or more sides not parallel to each other. The multi-projection system provides high three-dimensional images and a high degree of immersion in images and further provides multi-view images, thereby making theater customers feel like they really exist in the space described through the images.
