VR Scene Transition via Headset Motion Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems rely on controller devices for scene transitions, which can be cumbersome and limit immersive interaction, as users must manually press buttons to switch between scenarios, lacking intuitive motion-based control.
Innovation Solution
A virtual reality system that uses a head-mount display device and processing device to detect motion displacements, comparing them to thresholds to seamlessly transition between virtual reality scenes based on user movements, such as jumping or squatting, allowing for dynamic and immersive scene changes without the need for manual button pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If controller devices with buttons are used for scene transitions, then scene switching can be achieved, but the operation becomes cumbersome and less immersive
Solution Approach 1:
The patent extracts the scene transition function from manual controller operations and relocates it to automatic motion-based triggering. The system monitors user motion states (running, jumping, squatting) and automatically triggers scene transitions when specific motion thresholds are met, eliminating the need for separate controller button presses for navigation.
Solution Approach 2:
The system enables self-service by allowing the user's natural body motions to directly control scene transitions without requiring manual controller manipulation. The motion detection system automatically interprets user movements and triggers appropriate scene changes, making the interface serve itself through the user's inherent actions rather than requiring learned controller operations.
2Adaptability or versatility
If manual button pressing is required for scene switching, then precise control is achieved, but the immersion and intuitiveness are reduced
Solution Approach 1:
The patent replaces the mechanical controller button-pressing system with a motion detection system that captures natural user movements. Instead of requiring users to press physical buttons on a controller, the system uses motion sensors to detect body movements and translates these into scene transition commands, substituting mechanical interaction with intuitive physical action.
Solution Approach 2:
The system introduces dynamics by making scene transitions responsive to real-time user motion states rather than static button presses. The scene switching becomes a dynamic process that adapts to the user's current movement state (running, jumping, squatting), creating a more versatile and intuitive interaction method that evolves with user behavior.
3Ease of operation
If motion displacement is used for scene transitions, then immersion is enhanced, but the system complexity increases
Solution Approach 1:
The motion detection system serves multiple functions: it not only triggers scene transitions but also potentially tracks user position, monitors activity levels, and provides feedback for other VR interactions. By making the motion detection capability universal, the patent justifies the added system complexity through multiple beneficial applications beyond just scene switching.

AI summary
A control method is utilized for switching virtual reality scenes in a virtual reality system. The virtual reality system includes a head-mount display device for displaying virtual reality visions. The control method includes operations of: providing a first virtual reality scene as the virtual reality visions to be displayed on the head-mount display device; obtaining a motion displacement of the head-mount display device; comparing the motion displacement with a threshold displacement; in response to the motion displacement being shorter than the threshold displacement, providing the first virtual reality scene in a first portion of the virtual reality visions and providing a second virtual reality scene in a second portion of the virtual reality visions according to the motion displacement; and, in response to the motion displacement exceeding the threshold displacement, providing the second virtual reality scene as the virtual reality visions to be displayed on the head-mount display device.
