Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audiovisual presentation systems are limited in providing a realistic experience due to their two-dimensional rectangular screens and lack of manipulation capabilities for audiovisual media, which detract from the sense of realism and interaction.
Innovation Solution
An audiovisual presentation system featuring a transparent system enclosure with projectors outside, interfacing with the Internet, remote computers, and video recorders, generating and presenting panoramic 3D images, and allowing users to manipulate video and audio parameters, utilizing a dome or spherical enclosure for immersive telepresence interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat rectangular screen is used for audiovisual presentation, then the device structure is simple, but the sense of realism and immersion is reduced
Solution Approach 1:
The patent employs a transparent spherical enclosure instead of a flat rectangular screen. The spherical geometry provides a three-dimensional immersive environment that enhances realism and immersion. Multiple projectors positioned around the sphere project images onto the transparent spherical surface, creating a panoramic 360-degree viewing experience that surrounds the audience, thereby resolving the contradiction between structural simplicity and sense of realism.
Solution Approach 2:
The invention transitions from two-dimensional flat screen display to three-dimensional spherical display. By projecting images onto the spherical surface from multiple angles, the system creates a volumetric viewing experience that envelops the audience, adding spatial depth and immersion dimensions that a flat screen cannot provide, thus improving realism while maintaining manageable structural complexity.
2Device complexity
If conventional projectors and screens are used, then the system complexity is low, but the capacity to manipulate and experience audiovisual media is limited
Solution Approach 1:
The transparent spherical enclosure system serves multiple functions: it acts as a projection surface, a structural support, and an immersive environment creator. The system can display various types of content including panoramic images, 360-degree videos, and interactive media. Multiple projectors can be controlled independently or collectively, enabling diverse manipulation capabilities for different presentation needs, thus achieving high adaptability without excessive complexity.
Solution Approach 2:
The transparent spherical enclosure acts as an intermediary between the projectors and the audience. It allows light transmission while providing a curved projection surface, enabling the system to manipulate light paths and create immersive visual experiences. The transparency of the sphere allows audience members to view the projected content from multiple angles while maintaining interaction with the environment, enhancing manipulation capacity.
3Reliability
If a transparent spherical enclosure with multiple projectors is used, then the sense of realism and immersion is enhanced, but the device complexity increases
Solution Approach 1:
The patent combines multiple projectors, a transparent spherical enclosure, and support structures into an integrated system. The projectors are positioned around the sphere and coordinated to project seamless panoramic images. The spherical enclosure merges the functions of screen, structural support, and immersive environment creator into a single element. This consolidation achieves high realism and immersion while managing overall system complexity through functional integration.

AI summary
An audiovisual presentation system includes a transparent system enclosure and at least one projector outside the system enclosure and generally directed toward an exterior surface of the system enclosure. The system enclosure is formed in a dome shape, a hemispherical shape, a spherical shape, or any other reasonable shape. The system can include a plurality of projectors to present individual images or can be computer altered to present a continuous, panoramic image. The image can be of any quality or format, including high definition (HD) three-dimensional (3D), and others. A plurality of audiovisual input stations may be disposed about an interior of the enclosure. Each station may include a podium, a computer, a video recorder, an audio device, and a user control interface. The station enables the user to manipulate the video camera and/or the video image as desired.
