Virtual Reality Frame Rotation for Dizziness Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality, fast-moving frames often cause inconsistency between visual and body perceptions, leading to dizziness due to obscured line of sight and the need for joysticks or locators, which can exacerbate disorientation.
Innovation Solution
A method and apparatus that guide the user's line of sight to the direction of gravity before fast-moving frames are displayed, using a head-mounted display, locator, and computing device to synchronize visual and body acceleration by rotating the frames and coordinate system to match the gravity direction.

Engineering Contradiction Analysis
1Productivity
If fast-moving frames are displayed in virtual reality, then the visual experience and immersion in the virtual world is improved, but the user experiences dizziness due to inconsistency between visual perception and body perception
Solution Approach 1:
The system performs preliminary action by detecting when fast-moving frames are about to occur and proactively guiding the user's line of sight to the direction of gravity before the fast movement happens. This advance preparation allows the user's visual and body perceptions to remain consistent during the subsequent fast-moving frames, preventing dizziness while maintaining immersive visual experience
2Productivity
If the user's line of sight is obscured by wearing HMD, then the virtual reality immersion is improved, but the user cannot perceive the surroundings and experiences disorientation during fast movement
Solution Approach 1:
The system uses the direction of gravity as an intermediary reference that connects the user's visual perception in the virtual environment with their body perception in the real world. By guiding the line of sight to align with gravity direction during fast-moving frames, the gravity vector serves as a common reference that reconciles the conflicting visual and vestibular signals, reducing disorientation while maintaining immersion

AI summary
A method, a virtual reality apparatus and a recording medium for displaying fast moving frames of virtual reality are provided. The method is adapted to a virtual reality apparatus including a head-mounted display (HMD), a locator and a computing device. In the method, the computing device executes an application of virtual reality, and displays frames of the application on the HMD. When fast moving of the frames of the application is about to be occurred, the computing device prompts the fast moving to guide a user wearing the HMD to turn a line of sight to a direction of gravity, and then fast moves a field of view of the frames to the direction of gravity.
