VR Theater Structure With Rotating Chairs for Wide-Angle Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional theater structures fail to provide a dynamic viewing experience for virtual reality, as they typically have fixed viewing angles and chair orientations, limiting the ability to view 2D or 3D images over a wide range of up to 360° horizontally and 120-360° vertically.
Innovation Solution
A virtual reality theater structure featuring a reflection screen with a 40-360° up-down and 120-360° left-right viewing angle, combined with a chair system that can rotate independently up to 360°, utilizing a projection system for polarized 3D images and buffering devices for smooth movement, allowing viewers to experience immersive virtual reality by rotating the chair up, down, left, and right.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed screen and fixed chair structure is used in a conventional theater, then the structure is simple and stable, but the viewing angle is limited and cannot provide immersive virtual reality experience
Solution Approach 1:
The patent applies dynamics by making the chair rotatable around a vertical axis to change viewing angles horizontally, and by making the screen adjustable in position and orientation. This allows the theater structure to adapt to different virtual reality viewing requirements while maintaining operational simplicity through controlled mechanical movements.
Solution Approach 2:
The theater structure is segmented into independent functional components: fixed projection equipment, adjustable screen, and rotatable chairs. This segmentation allows each component to be optimized independently - the projection system remains simple and stable while the screen and chairs provide the necessary adaptability for immersive viewing.
2Adaptability or versatility
If the chair is made rotatable to provide wide viewing angle, then the virtual reality experience is enhanced, but the structure and operation become more complex
Solution Approach 1:
The chair rotation system is designed to be easily operable by viewers themselves, allowing them to independently adjust their viewing angle without requiring complex control systems or assistance. This self-service approach maintains ease of operation while providing full rotational capability for immersive virtual reality experience.
3Adaptability or versatility
If the screen coverage is expanded to 360° horizontal and 120-360° vertical, then the virtual reality image quality is improved, but the device complexity increases
Solution Approach 1:
The projection system is designed with multi-functionality to handle various screen positions and orientations. The same projection equipment can project images onto the screen regardless of its adjusted position, and the screen can serve multiple viewing angles without requiring separate projection systems for each angle, thereby maintaining simplicity while achieving wide coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a fully immersive virtual reality experience by allowing viewers to see 2D or 3D images from all directions, enhancing the virtual reality effect by providing a wide range of motion for the chair and screen, thereby overcoming the limitations of fixed viewing angles in traditional theaters.
Implementation Method 1
a reflection screen which has a view angle of up down 40-360° and left right 120-360°, effective range for virtual reality, and has a reflection rate of 1.1 gain or more

AI summary
A virtual reality theater structure, including a reflection screen which has a view angle of up down 40-360° and left right 120-360°, an effective range for virtual reality, and has a reflection rate of 1.1 gain or more; a projection system for projecting the 2D or 3D image for left eye and the 2D or 3D image for right eye on the reflection screen; and a chair structure that is rotatable up and downward 40-120° and left and rightward 120-360° where each chair is rotated with area of independent range that is separated individually.
