VR Ride Motion Exaggeration via Sensor Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality ride systems struggle to provide an exhilarating experience while minimizing the likelihood of motion sickness, as they often limit the magnitude of movement to match physical ride vehicle motion.
Innovation Solution
A virtual reality ride system that predicts the ride vehicle's movement profile using sensors and a prediction model, allowing it to generate and present movement-exaggerated virtual reality content by adjusting default content to incorporate a target perceived movement magnitude greater than the predicted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If virtual reality content is limited to match physical ride vehicle motion magnitude, then motion sickness is minimized, but ride excitement and exhilaration are reduced
Solution Approach 1:
The system changes the parameter of movement magnitude in virtual reality content relative to physical motion. By applying a movement exaggeration factor greater than 1.0, the virtual movement magnitude is increased while maintaining synchronization with physical motion timing, thereby enhancing excitement without causing motion sickness
Solution Approach 2:
The system continuously monitors actual ride vehicle motion through sensors (accelerometers, gyroscopes) and adjusts virtual reality content in real-time. This feedback loop ensures that virtual movement remains synchronized with physical motion while applying the exaggeration factor to enhance the riding experience
2Productivity
If movement magnitude in virtual reality is exaggerated beyond physical motion, then ride excitement is enhanced, but motion sickness likelihood increases
Solution Approach 1:
The system applies a controlled movement exaggeration factor (greater than 1.0) to scale up virtual movement magnitude while maintaining temporal synchronization with physical motion. This parameter adjustment enhances excitement without creating perceptual discrepancies that would cause motion sickness
Solution Approach 2:
The system dynamically adjusts virtual reality content based on real-time physical motion data. The movement exaggeration factor is applied adaptively throughout the ride, allowing the system to respond to varying motion intensities and maintain optimal balance between excitement and comfort
3Object-affected harmful factors
If virtual reality content is synchronized with physical motion timing, then motion sickness is reduced, but the ability to provide exhilarating experience is limited
Solution Approach 1:
The system maintains temporal synchronization with physical motion timing while changing the magnitude parameter through the movement exaggeration factor. This allows virtual events to occur at the same time as physical motion, preserving comfort while enhancing the exhilarating experience through amplified movement perception

AI summary
A virtual reality (VR) ride system comprising: a ride vehicle configured to support a rider and traverse a variable ride environment; an electronic display configured to present virtual reality, VR, image content to the rider carried through the variable ride environment by the ride vehicle; and one or more processors communicatively coupled to the electronic display and one or more sensors, wherein the one or more sensors are configured to record sensor data indicative of a movement profile of the ride vehicle in the variable ride environment, and wherein the one or more processors are configured to: receive the sensor data from the one or more sensors; determine a predicted ride vehicle trajectory of the ride vehicle within the variable ride environment based on the sensor data indicative of the movement profile of the ride vehicle and a ride vehicle movement prediction model, wherein the predicted ride vehicle trajectory corresponds to a predicted movement magnitude of the ride vehicle during a predicted movement duration; determine a target perceived movement magnitude that is greater than the predicted movement magnitude; and determine movement-exaggerated VR image content to be presented on the electronic display during the predicted movement duration by adjusting default image content to incorporate the target perceived movement magnitude.
