Solution Overview

Problem

Current virtual reality (VR) systems lack efficient and convenient methods for user identity authentication, which is crucial for secure operations such as in-application purchases and parental control, often relying on cumbersome password entry or insecure biometric methods.

Innovation Solution

The implementation of eye physiological characteristic-based authentication using VR devices, where user interactions initiate a service, and eye sensors collect and compare iris or eye print data with pre-stored samples for secure and fast authentication, communicating with a server to verify user identity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional password entry or basic biometric methods are used for user authentication in VR systems, then implementation simplicity is maintained, but authentication security and user convenience deteriorate

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system is segmented into multiple independent components: eye tracking module, iris recognition module, and authentication decision module. Each component performs a specific function, allowing the system to achieve high security through multi-factor authentication while maintaining manageable complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by capturing and storing user eye physiological characteristics during the initial setup phase. This pre-captured biometric data is then used for rapid authentication during subsequent login operations, eliminating the need for complex real-time verification processes and improving both security and convenience.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If complex authentication procedures are implemented to enhance security, then authentication security improves, but user convenience and authentication speed deteriorate

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system replaces mechanical authentication methods (password typing, card insertion) with optical-based eye tracking and iris recognition. This substitution enables contactless, rapid authentication that is both highly secure and convenient, reducing authentication time while maintaining strong security credentials.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The authentication system leverages the user's own eye physiological characteristics as the authentication credential. The user's unique biometric features serve as both the authentication method and the credential, eliminating the need for external authentication devices or complex verification procedures, thereby reducing authentication time while ensuring security.

Inventive Principle:

Principle #25Self-service

3Device complexity

If basic authentication methods are used to maintain system simplicity, then device complexity is reduced, but authentication security and immersive experience deteriorate

Engineering Contradiction:

Improveauthentication system complexityVSAvoidauthentication security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The eye tracking system serves multiple functions: it tracks user gaze for natural interaction control, captures iris patterns for biometric authentication, and monitors eye movements for security verification. This multi-functionality allows the system to achieve high authentication security while avoiding the need for separate dedicated authentication hardware, thus managing complexity effectively.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If traditional authentication interfaces are used in VR, then ease of implementation is maintained, but user convenience and immersive experience deteriorate

Engineering Contradiction:

Improveuser convenienceVSAvoidauthentication interface complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system introduces an intermediary layer that translates complex authentication processes into natural eye movement-based interactions. The eye tracking technology acts as a mediator between the user's natural gaze and the authentication system, allowing users to authenticate through intuitive eye movements without dealing with complex interfaces, thereby improving convenience while managing implementation complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

In an implementation, one or more user interactions from a virtual reality (VR) device user for initiating a service in a VR scenario of a VR application are detected. One or more eye physiological characteristics of the VR device user are obtained for user identity authentication. The obtained one or more eye physiological characteristics are compared with one or more pre-stored eye physiological characteristics samples. The VR device user is authenticated if the one or more eye physiological characteristics match at least a portion of the one or more pre-stored eye physiological characteristics samples, and a server that provides and performs the service is communicated with.
