Information Display Device With Movement-Based VR Warning Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR headsets struggle with setting appropriate boundaries for warnings, leading to either unnecessary interruptions or missed collision alerts, which disrupt the immersive experience.
Innovation Solution
An information processing apparatus that adjusts a self-area based on user movement, using external cameras and sensors to detect obstacles and dynamically set safe movement boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warning area is set wider to ensure safety, then collision prevention is improved, but unnecessary warnings increase and immersive experience deteriorates
Solution Approach 1:
The self-area is dynamically adjusted based on user movement state. When the user is stationary, a larger self-area is used for safety. When the user is moving, the self-area is reduced or shifted to match the movement direction, preventing unnecessary warnings while maintaining safety for actual obstacles.
Solution Approach 2:
The system changes the parameters of the self-area (position, size, shape) based on detected movement parameters. The processor adjusts the self-area configuration in real-time according to the user's movement state, optimizing the balance between safety and immersion.
2Ease of operation
If the warning area is set narrower to maintain immersion, then immersive experience is improved, but collision detection reliability deteriorates
Solution Approach 1:
The self-area dynamically expands or contracts based on movement. When stationary, the full self-area provides comprehensive safety coverage. When moving, the self-area adjusts to focus on relevant obstacles in the movement path, maintaining detection reliability without excessive warnings.
3Device complexity
If a fixed self-area is used for simplicity, then device complexity is reduced, but adaptability to changing environments deteriorates
Solution Approach 1:
The system automatically detects user movement and adjusts the self-area without user intervention. The processor monitors movement state and autonomously reconfigures the self-area, providing environmental adaptability while keeping the user interface simple.
Solution Approach 2:
The system uses feedback from movement detection sensors to continuously adjust the self-area. The detected movement state feeds back to the processor, which then modifies the self-area configuration accordingly, creating a closed-loop adaptive system.
