Solution Overview

Problem

In virtual reality systems, accessories such as controllers and sensors often require manual setting to associate with specific body parts, which can be inconvenient, especially for accessories that need to be fixed in place.

Innovation Solution

A method and system for accessory pairing that detects the position of an accessory and a user body part using image recognition and identifying information, allowing the accessory to be automatically configured to pair with the correct body part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual setting is used to associate accessory with body part, then pairing accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvepairing accuracyVSAvoidease of operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The accessory automatically performs pairing by detecting its own position relative to body parts using sensors and image data, eliminating the need for manual configuration. The accessory independently determines which body part it should be associated with based on spatial detection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical pairing process is replaced with an automated optical and sensor-based detection system. The system uses image capture devices and position detection to automatically determine pairing relationships, substituting user manual operations with automated technological processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If accessory is fixed with wrist strap or devil felt, then reliability of pairing is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvereliability of pairingVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary position detection and pairing configuration before the accessory is physically fixed to the body part. By detecting position and establishing pairing relationships in advance, the system eliminates the need to manually reconfigure after physical attachment, thereby maintaining ease of operation while ensuring reliable pairing.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If automatic pairing is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The computing device performs multiple functions including position detection, image processing, and pairing configuration using a single integrated system. The image capture device serves both for visual feedback and for determining accessory-to-body-part relationships, reducing the need for separate specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)
