Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR technology isolates participants from the real environment, posing safety risks and limiting their experience, as they are unable to control their movements effectively within the virtual environment.
Innovation Solution
A multi-function VR human-computer interaction and external environment simulator that uses a base, hydraulic rods, and a controller to allow participants to move and interact within the virtual environment in a more immersive and controlled manner, simulating real-world movements and actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If participants interact directly with the virtual environment through sensing devices, then immersion and visual experience are improved, but safety risks increase and participants become isolated from the real environment
Solution Approach 1:
The patent introduces a motion simulator as an intermediary device between the participant and the virtual environment. The simulator includes a motion platform that can move in multiple degrees of freedom, providing physical motion feedback that corresponds to the virtual environment while maintaining a physical connection to the real world through the simulator structure itself
Solution Approach 2:
The system segments the interaction into two independent channels: visual input through VR headsets and tactile/motion feedback through the motion simulator. This segmentation allows each channel to be optimized independently - the VR headset provides immersive visuals while the motion simulator provides safe, controlled physical feedback with emergency stop capabilities
2Illumination intensity
If participants are isolated in the virtual environment, then visual immersion is improved, but real-world experience and control are limited
Solution Approach 1:
The motion simulator provides real-time tactile feedback to the participant based on their actions in the virtual environment. When the participant moves or interacts in VR, the motion platform responds with corresponding physical movements, creating a closed-loop feedback system that enhances both immersion and control. The controller detects participant inputs and translates them into both virtual actions and physical motion responses
Solution Approach 2:
The motion simulator serves multiple functions simultaneously: it acts as a safety mechanism with emergency stop capabilities, provides immersive motion feedback, enables realistic physical interaction, and maintains connection to the real environment. This multi-functionality resolves the contradiction by making the same system element beneficial for both immersion and control

AI summary
A VR human-computer interaction and external environment simulator and a simulation method. The simulator comprises a base (1), a bottom rotating base (2), an outer ring (3), an inner ring (4), a seat (5), and a controller. The inner ring (4) is rotatably fitted into the outer ring (3); the inner ring (4) is connected with an inner ring driving motor which is used for driving the inner ring (4) to rotate in an X-Z plane; the seat (5) is fixedly mounted inside the inner ring (4); the controller is separately connected with a bottom rotating motor (13), a hydraulic pump, an outer ring driving motor (14), and the inner ring driving motor, wherein an X axis and a Z axis form a horizontal plane; a Z axis is an axis which is perpendicular to the horizontal plane. The present invention has the following advantages: a participant can control himself/herself within the maximum range, and his/her perception in a real environment can be achieved by means of the motion trajectory of the simulator; practicability and safety are provided, and the real experience of the participant is also improved.
