Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current immersive audiovisual content reproduction technologies are limited in providing 180° to 360° visual coverage for personal or group use without requiring additional devices, and existing solutions are either expensive or restrictive, such as dome systems or VR glasses that isolate users.
Innovation Solution
A compact, all-in-one reproducing-projecting system that projects immersive and non-immersive content using standard formats, adaptable to indoor spaces, allowing for interactive and customizable experiences through Internet connectivity, domotics control, and gesture-based navigation without the need for headgear or separate projectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dome projection systems are used to achieve 360° visual coverage, then immersive content reproduction is improved, but system cost and complexity increase significantly
Solution Approach 1:
The system divides the projection task into multiple standard projectors arranged in specific configurations (e.g., three projectors for 360° coverage or two projectors for 180° coverage). Each projector handles a specific angular sector, and their projections are merged to create the complete immersive environment. This segmentation allows achieving dome-like coverage without requiring a single complex dome system.
Solution Approach 2:
The system uses standard, commercially available projectors that can be used for both traditional 2D projection and immersive 360° content projection. These projectors are configured to project onto flexible screens or specific geometric arrangements, allowing the same hardware to serve multiple purposes. The system adapts to different content types (immersive and non-immersive) using the same physical infrastructure.
2Adaptability or versatility
If VR glasses are used for immersive content reproduction, then user immersion is improved, but user isolation from real environment and device complexity increase
Solution Approach 1:
The system extracts the immersive experience from the confines of VR headsets and projects it directly into the physical environment. By projecting 360° content onto surrounding surfaces, the system makes the immersive experience visible and accessible to all users in the space without requiring them to wear head-mounted displays. This extracts the immersion capability from the user's personal device and makes it an environmental feature.
Solution Approach 2:
The system introduces flexible projection screens and carefully positioned projectors as intermediaries between the content source and the users. These intermediaries create an immersive environment that naturally engages users without requiring them to don additional devices. The projection surfaces act as a mediator that delivers the immersive experience passively to all users simultaneously.
3Adaptability or versatility
If multiple projectors are deployed for 360° projection, then visual coverage is improved, but synchronization and system complexity increase
Solution Approach 1:
The system implements synchronization mechanisms where projectors are coordinated through centralized control that monitors and adjusts timing, brightness, and content distribution across multiple projectors. This feedback-based approach ensures that all projectors work in unison to create a seamless immersive experience, with automatic adjustment for any variations in projection timing or intensity.
Solution Approach 2:
The system performs preliminary configuration and calibration of multiple projectors before operation. During setup, the system pre-synchronizes the projectors, pre-positiones the flexible screens, and pre-configures the content mapping for each projector. This preliminary action reduces the complexity during actual operation, as the synchronization parameters are already established and optimized.
4Manufacturing precision
If specialized immersive content production software is used, then content quality is improved, but production cost and accessibility decrease
Solution Approach 1:
The system uses software that can process and adapt standard video formats into immersive 360° projections without requiring specialized production software. The system copies and transforms existing content through automated equirectangular projection and geometric correction algorithms, making high-quality immersive content production accessible without expensive specialized tools. This copying approach allows standard content to be repurposed for immersive displays.
Solution Approach 2:
The system employs software that automatically adjusts projection parameters (such as equirectangular to fisheye conversion, geometric distortion correction, and brightness normalization) to optimize content for the projection environment. These automated parameter changes enable high-quality immersive output from standard input content, eliminating the need for manual adjustment by specialists and making the process accessible to general users.
