VR Platform Levitation Film Motion Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems limit natural movement, such as walking or running, to an optical representation and do not allow for free movement within the virtual environment.
Innovation Solution
A system comprising a stationary base, a movable platform levitated using actuators, and a surrounding film that moves to compensate for user movements, allowing for free movement within a virtual reality environment while maintaining the user's position on the platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a person moves freely on the platform, then natural movement in virtual reality is enabled, but the person's position on the platform changes which breaks immersion
Solution Approach 1:
Motion sensors detect the person's movements on the platform and provide feedback to the controller, which then actuates the film to compensate for the movements and maintain the person's position
Solution Approach 2:
The film acts as an intermediary between the person and the platform, moving in response to detected movements to compensate for position changes and maintain immersion
2Stability of the object's composition
If the platform is fixed on the base, then structural stability is achieved, but space is required for mechanical support structures
Solution Approach 1:
The mechanical support structure is replaced with a magnetic field-based levitation system using magnets on both the base and platform, eliminating the need for physical mechanical supports
Solution Approach 2:
The platform transitions from a fixed mechanical connection to a controllable magnetic field connection, allowing the stability parameter to be maintained while changing the spatial configuration

Implementation Method 1
The at least one levitation actuator is designed as an electromagnetic actuator which puts the platform into the desired levitation state with the aid of electromagnetic forces
Implementation Method 2
The at least one motion sensor can include a camera that optically captures the motion(s) of a person located on the platform
