Solution Overview

Problem

In development and design activities involving virtual reality systems, existing technologies face challenges in allowing multiple users to share the same virtual perspective without causing nausea due to differing head movements, which can lead to discomfort and disorientation.

Innovation Solution

A method and system that allows virtual reality glasses to detect head positions and orientations, enabling one user to set the perspective for others, with adaptive display adjustments to maintain synchronization while minimizing nausea-inducing discrepancies in head movements, such as dividing the display area into sections showing the same perspective and the user's own perspective, and adjusting these based on movement differences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple users wear virtual reality glasses and each views the virtual environment from their own perspective based on their head movements, then each user experiences accurate spatial orientation, but multiple users cannot collaborate effectively as they see different views of the same virtual object

Engineering Contradiction:
Improvecollaboration capabilityVSAvoidperspective synchronization
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent segments the display area of the virtual reality glasses into multiple independent display regions, each showing the virtual environment from a different user's perspective. This allows multiple users to view their respective perspectives simultaneously within the same device without interfering with each other's spatial orientation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The virtual reality glasses are designed to serve multiple functions: they can operate in individual mode where each user sees their own perspective, and in collaborative mode where multiple users can view the same virtual environment from different perspectives simultaneously, enabling effective collaboration while maintaining spatial accuracy for each user.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the virtual environment is displayed from the same perspective for all users to enable collaboration, then users can see the same virtual object from a unified view, but users experience nausea and discomfort due to discrepancies between their actual head movements and the displayed perspective

Engineering Contradiction:
Improvecollaboration capabilityVSAvoiduser discomfort
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The display area is segmented into multiple regions, with each region dedicated to a specific user's perspective. This segmentation allows the system to provide a unified collaborative view while simultaneously maintaining accurate individual perspective tracking, preventing the sensory conflict that causes nausea.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the display have different quality characteristics tailored to each user's needs. The display dynamically adjusts the content and perspective in each local region based on the corresponding user's head movements and position, ensuring that each user receives the appropriate visual information for their spatial orientation while enabling collaboration.

Inventive Principle:
Principle #3Local quality

3Loss of information

If the display area is completely used to show the virtual environment from one perspective, then maximum visual information is provided to the primary user, but additional users cannot simultaneously view their own perspectives

Engineering Contradiction:
Improvevisual information completenessVSAvoidmulti-user support
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The display area is divided into multiple segments or regions, each capable of displaying the virtual environment from a different user's perspective. This segmentation enables the system to provide complete visual information to multiple users simultaneously without compromising the visual completeness for any individual user.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes the dimensional space of the display area more efficiently by arranging multiple perspective views in different spatial regions of the same display surface. This allows the system to maintain full visual information for each user while supporting multiple users concurrently, effectively adding a multi-user dimension to the display capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
