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

VSEngineering 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

Engineering Contradiction:
Improvecollision preventionVSAvoidimmersive experience
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the warning area is set narrower to maintain immersion, then immersive experience is improved, but collision detection reliability deteriorates

Engineering Contradiction:
Improveimmersive experienceVSAvoidcollision detection
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a fixed self-area is used for simplicity, then device complexity is reduced, but adaptability to changing environments deteriorates

Engineering Contradiction:
Improveself-area managementVSAvoidenvironmental adaptation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #23Feedback
