VR Motion Platform Feedback Control for Motion Sickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience motion sickness due to the mismatch between the motion sensations and visual cues in virtual reality (VR) content, as motion platforms are often not considered during VR content creation, leading to unfamiliarity and dizziness.
Innovation Solution
A motion sickness reduction apparatus for VR motion platforms that receives content motion data, compares it with motion detection data, and generates final motion control data to minimize sickness by adjusting motion in sections where the motion detection data does not follow the control data, using algorithms to reduce the amplitude or apply filters to the motion control data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion platforms are used to generate motion sensations in VR content, then the sense of reality and immersion is improved, but motion sickness occurs due to mismatch between motion sensations and visual cues
Solution Approach 1:
The system uses sensing devices to detect actual motion state of the motion platform, compares it with intended motion control data, and uses this feedback information to identify motion sickness-causing sections and generate corrected motion control data that reduces the mismatch between visual and motion cues
Solution Approach 2:
The system modifies motion control parameters by generating final motion control data with adjusted amplitude and timing characteristics based on detected discrepancies, transforming the motion parameters to reduce motion sickness while preserving immersion
2Object-affected harmful factors
If motion control data is adjusted to reduce motion sickness, then user comfort is improved, but the fidelity of motion reproduction may be reduced
Solution Approach 1:
The system applies motion control adjustments selectively only in identified motion sickness-causing sections rather than uniformly across all content, preserving motion fidelity in non-problematic sections while correcting issues where they occur
Solution Approach 2:
The system generates final motion control data that partially adjusts motion parameters only when necessary to reduce motion sickness, rather than applying full correction throughout, thereby maintaining balance between comfort and fidelity

AI summary
Disclosed is a method comprising the steps of: receiving an input of content motion data included in VR content; transmitting, to a motion device, motion control data corresponding to the input content motion data to control movement of the motion device; receiving, from a predetermined sensing apparatus, motion detection data corresponding to a movement state of the motion device; selecting a motion sickness-causing section by using a difference between the motion control data and the motion detection data; generating final motion control data according to a preset algorithm such that the level of motion sickness in the selected motion sickness-causing section is minimized during a preset content reproduction section, and storing the generated final motion control data; and when 3D VR content is reproduced, transmitting, to the motion device, the final motion control data stored in the previous step so as to control the movement of the motion device.
