Multi-Axis Motion-Controlled VR Chair to Reduce Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems fail to provide an immersive experience and often cause motion sickness due to the lack of multi-axis motion control, with complex component placement and cabling issues complicating system installation.
Innovation Solution
A self-contained VR system featuring a multi-axis motion-controlled chair integrated with a VR headset, where the chair's motion is synchronized with virtual reality content using defined motion profiles, incorporating pitch and yaw rotations, and optional user control, along with haptic feedback and directional audio, to create immersive sensations without actual physical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-axis motion control is added to VR systems to enhance immersion, then user immersion is improved, but device complexity increases
Solution Approach 1:
The patent combines the motion control system, VR display system, and computational processing equipment into a single integrated chair unit. This merging eliminates the need for separate component placements and complex cabling between multiple devices, thereby reducing overall system complexity while maintaining multi-axis motion control capability for enhanced immersion.
Solution Approach 2:
The chair is designed to perform multiple functions: it serves as both the seating structure and the motion control platform, while also housing the VR display and processing equipment. This multi-functionality reduces the number of separate components needed, simplifying the system architecture while providing complex motion control for improved user immersion.
2Adaptability or versatility
If complex component placement and cabling are used to achieve multi-axis motion control, then motion control capability is improved, but ease of installation deteriorates
Solution Approach 1:
By integrating all motion control components, VR display, and processing equipment into a single chair unit, the patent eliminates the need for complex inter-component cabling and placement. The slip ring mechanism provides a simplified power and signal transfer solution, making installation straightforward while maintaining full motion control capability.
3Device complexity
If traditional VR systems are used without multi-axis motion control, then device complexity is reduced, but motion sickness increases
Solution Approach 1:
The integrated chair system provides coordinated multi-axis motion control that synchronizes physical movement with visual content, reducing the sensory conflict that causes motion sickness. The slip ring enables this motion control while maintaining a relatively simple overall system architecture through component integration.

AI summary
An improved virtual reality system comprises a chair 110 integrated with a pedestal 120, which contains a motion platform 150 and base 160. The chair 110 can be rotated continuously in the yaw axis by a stepper motor 230 and substantially in the pitch axis by an additional stepper motor 240 in coordination with the content of the VR display as directed by a chair controller located on the motion platform 150.
