Solution Overview

Problem

Existing biometric feature enrollment methods in virtual and augmented reality systems are cumbersome, inefficient, and create a significant cognitive burden on users, leading to prolonged processes that waste energy and distract from the user experience.

Innovation Solution

Implement improved user interfaces and methods that provide intuitive feedback through visual and audio cues, using display generation components and cameras to enhance biometric enrollment by adjusting visual effects and prioritizing error corrections, thereby reducing user input and conserving energy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional biometric enrollment methods are used, then the process is completed, but the process is cumbersome and creates significant cognitive burden on users

Engineering Contradiction:

Improvebiometric enrollment processVSAvoidenrollment interface complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system provides real-time visual feedback by displaying a representation of the captured biometric feature view in the enrollment user interface. This allows users to see what the camera is capturing and understand whether they are positioning themselves correctly, reducing cognitive burden and making the enrollment process more intuitive.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary representation layer between the camera capture and the user. Instead of directly showing raw camera footage or technical data, the system creates a processed visual representation that mediates the interaction, making it easier for users to understand their enrollment progress and positioning.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If conventional biometric enrollment methods are used, then the enrollment is completed, but the process takes longer than necessary

Engineering Contradiction:

Improveenrollment speedVSAvoidenrollment duration

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The real-time visual feedback mechanism allows users to immediately see the impact of their positioning adjustments, enabling faster convergence to the correct enrollment position. Users don't need to guess or make multiple trial adjustments, thereby reducing the overall enrollment time.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary processing of the camera feed to create the visual representation before displaying it to the user. This pre-processing prepares the visual information in advance, allowing for faster response times and reducing the perceived delay during the enrollment process.

Inventive Principle:

Principle #10Preliminary action

3Use of energy by moving object

If conventional biometric enrollment methods are used, then the enrollment process continues, but energy of the computer system is wasted

Engineering Contradiction:

Improvesystem energy consumptionVSAvoidbattery power

Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

By providing visual feedback that clearly indicates enrollment progress and status, the system enables users to understand when the enrollment is complete or when adjustments are needed. This prevents prolonged enrollment sessions where the camera and processing systems continue to operate unnecessarily, thereby conserving energy.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The visual representation system allows users to self-monitor their enrollment progress without requiring additional system prompts or status checks. Users can independently determine when they are properly positioned and when enrollment is complete, reducing unnecessary processing cycles and energy consumption.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If conventional biometric enrollment methods are used, then the enrollment proceeds, but user experience is distracted and diminished

Engineering Contradiction:

Improveuser experience qualityVSAvoidcognitive burden

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The visual feedback provided through the enrollment user interface creates a more engaging and intuitive user experience. Users can visually confirm that the system is capturing the correct biometric data, which reduces frustration and cognitive load compared to conventional methods that provide little or no visual feedback.

Inventive Principle:

Principle #23Feedback
