Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional vision testing 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
Solution Approach 1:
The patent implements dynamic adjustment of test parameters including visual stimulus characteristics (size, contrast, duration), inter-stimulus intervals, and test difficulty levels based on real-time user performance. This allows the system to adapt to each user's visual capabilities, improving measurement precision while using commercially available head-mounted display equipment.
Solution Approach 2:
The system changes multiple test parameters simultaneously including stimulus luminance, duration, spatial frequency, and temporal characteristics to optimize assessment accuracy. These parameter changes are controlled through software algorithms that analyze user responses and adjust subsequent test conditions to maximize diagnostic precision.
2Adaptability or versatility
If traditional vision testing methods are used, then the equipment required is minimal and accessible, but the ability to provide personalized and adaptive feedback is limited
Solution Approach 1:
The patent implements real-time feedback loops where user responses to visual stimuli are immediately analyzed and used to adjust subsequent test parameters. The system provides adaptive feedback through audio instructions and visual cues, personalizing the testing experience for each user while maintaining relatively simple equipment requirements through intelligent software control.
Solution Approach 2:
The system uses commercially available head-mounted display equipment that serves multiple functions: presenting visual stimuli, tracking user eye movements, providing audio feedback, and capturing user responses. This multi-functionality enables personalized adaptive feedback without requiring specialized dedicated equipment for each function.
3Ease of operation
If traditional vision testing methods are used, then the testing environment is fixed and controlled, but the accessibility for home use and remote testing is not possible
Solution Approach 1:
The patent uses a head-mounted display as an intermediary device that brings the controlled testing environment to the user's location. This portable platform delivers consistent visual stimuli and captures standardized user responses, enabling reliable vision assessment in home settings without requiring the user to visit a clinical facility.
Solution Approach 2:
The system performs preliminary calibration and setup procedures through the head-mounted display before beginning the actual vision test. This includes eye-tracking calibration, stimulus parameter verification, and user instruction provision, ensuring testing consistency is established before data collection begins in the home environment.

AI summary
This application is directed to implementing a vision test based on an avatar in a virtual environment. An electronic device includes a head-mounted display. The electronic device executes a user application configured to enable a virtual vision test, and generates a virtual reality (VR) user interface corresponding to a three-dimensional (3D) virtual environment. The electronic device obtains user information of a user associated with the electronic device, and concurrently displays an avatar and a sequence of visual stimuli on the VR user interface. While displaying each respective visual stimulus, the electronic device determines avatar characteristics based on the user information and the respective visual stimulus, and adjusts display of the avatar adaptively based on the avatar characteristics. The avatar characteristics includes a location of the avatar in the 3D virtual environment.
