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 system employs a multi-functional electronic device that integrates display, sensor array, speaker, and processor capabilities into a single platform. This universal device can perform vision testing while dynamically adjusting parameters based on real-time sensor feedback, thereby improving measurement precision without proportionally increasing overall system complexity.
Solution Approach 2:
The testing system implements dynamic parameter adjustment during the vision test by processing real-time sensor data and modifying test stimuli accordingly. This dynamic capability enhances measurement accuracy by adapting to user responses, while the integration within a single electronic device keeps the complexity manageable.
2Adaptability or versatility
If traditional vision testing methods are used, then the equipment is simple and accessible, but the testing environment is locked and home implementation is not possible
Solution Approach 1:
The system leverages a universal electronic device with integrated display, sensors, speaker, and processor that can function as a complete vision testing system. This multi-functional approach enables the system to operate in various environments including home settings, thereby improving adaptability while utilizing readily available household devices rather than requiring specialized equipment.
Solution Approach 2:
The system provides self-guided vision testing through audio instructions generated by the integrated speaker and processed through the device's processor. Users can independently complete vision tests without requiring professional operators or specialized facilities, enabling home implementation while the integrated nature of the electronic device keeps complexity requirements reasonable.
3Measurement precision
If dynamic parameter adjustment is implemented, then vision assessment accuracy is improved, but the system complexity increases
Solution Approach 1:
The system merges the display, sensor array, speaker, and processor into an integrated electronic device architecture. This consolidation allows dynamic parameter adjustment and real-time processing to occur within a unified system, improving vision test accuracy while avoiding the complexity increase that would result from separate interconnected components.
Solution Approach 2:
The system implements real-time feedback processing by continuously analyzing sensor data during vision testing and dynamically adjusting test parameters accordingly. This feedback mechanism enhances measurement precision through adaptive parameter modification, while the integrated processor within the electronic device handles the computational complexity efficiently without requiring external processing systems.
4Ease of operation
If voice-guided instructions are provided in real-time, then user guidance and testing accuracy are improved, but processing requirements and system complexity increase
Solution Approach 1:
The system combines audio output capabilities through the integrated speaker with real-time processor analysis of sensor data. This merging allows voice-guided instructions to be generated and delivered within the same electronic device that performs the vision testing, improving ease of operation through quality guidance while containing processing complexity within the device's integrated architecture.
Solution Approach 2:
The system provides continuous real-time processing and audio feedback throughout the vision testing process. The processor continuously analyzes sensor data and the speaker continuously provides guidance instructions, maintaining uninterrupted useful action that improves user guidance quality. The integrated electronic device handles this continuous processing efficiently, managing complexity through its unified design rather than requiring separate continuous processing systems.

AI summary
This application is directed to implementing a vision test based on real-time audio instructions in a virtual environment. An electronic device includes a display, one or more sensors, and a speaker. While presenting on the display a temporal sequence of visual stimuli, the electronic device obtains a stream of sensor data captured by the one or more sensors. Each respective visual stimulus corresponds to a subset of sensor data indicating a user's response to the respective visual stimulus. The electronic device generates a plurality of vision features based on the temporal sequence of visual stimuli and the stream of sensor data. A sequence of audio instructions is adaptively generated based on the plurality of vision features, and each respective audio instruction corresponds to a subset of respective vision features. The sequence of audio instructions is played successively by the speaker to guide the user in the virtual vision test.
