Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional vision test methods are used, then the testing process is simple and can be performed with basic equipment, but the assessment accuracy is reduced and dynamic adjustment of test parameters is not possible

Engineering Contradiction:

Solution Approach 1:

The patent implements dynamic adjustment of visual stimulus parameters (size, position, depth) based on real-time head orientation tracking and user responses. The test adapts its difficulty and configuration during execution, allowing precise measurement of depth perception and visual acuity while maintaining user engagement and accurate assessment through continuous parameter optimization

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system continuously monitors user responses and head orientation, then uses this feedback to dynamically adjust subsequent stimulus presentation. This closed-loop feedback mechanism enables the system to optimize test parameters in real-time, improving measurement precision by adapting to individual user capabilities while maintaining manageable complexity through automated control

Inventive Principle:

Principle #23Feedback

2Ease of operation

If traditional vision tests are used, then the equipment required is simple and accessible, but the tests cannot be properly implemented for home use and lack controlled testing conditions

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent utilizes a head-mounted display device that serves multiple functions: displaying visual stimuli, tracking head orientation, and presenting test results. This multi-functional device enables reliable controlled testing conditions to be achieved in home environments, as the single device provides both the stimulus presentation and the necessary tracking capabilities without requiring separate specialized equipment

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically tracks head orientation and adjusts stimulus parameters without requiring external operator intervention. This self-service capability allows the test to maintain reliable controlled conditions while being easily operable at home, as the device autonomously manages test configuration and adaptation throughout the assessment process

Inventive Principle:

Principle #25Self-service

AI summary

A vision test can be performed for evaluating eye depth perception in a virtual environment. An electronic device, such as a head-mounted display, can execute a visual assessment application, including generating a user interface corresponding to a three-dimensional (3D) virtual environment. The electronic device may display a first visual stimulus at a first depth in the user interface, and the first depth can be measured on a first line of sight. The electronic device may display the first visual stimulus at a second depth in the user interface, and the second depth can be distinct from the first depth and measured on the first line of sight. The electronic device may obtain one or more user responses to displaying of the first visual stimulus. Based on the one or more user responses, the electronic device may determine a depth perception level for a user associated with the electronic device.
