Solution Overview
Problem
Current vision training methods lack the ability to dynamically adjust flicker rates to effectively improve visual perception and response to objects and images in both central and peripheral fields of vision, which is crucial for various fields such as sports and occupational tasks like surgery.
Innovation Solution
A vision training system that utilizes a display device with a flicker generator to adjust the flicker rate between 3 Hz and 40 Hz, controlled by a display driver, and includes switchable lenses with zones that can be electrically adjusted to obscure or clear vision, allowing for dynamic visual content presentation and adjustable difficulty levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed flicker rate is used in vision training, then the training method is simple to implement, but it cannot dynamically adapt to different vision training needs and difficulty levels
Solution Approach 1:
The patent implements a flicker generator that can dynamically adjust the flicker rate between 3 Hz and 30 Hz based on training requirements. The system transitions from static fixed-frequency operation to dynamic variable-frequency operation, allowing the flicker rate to be modified during vision training sessions to match different difficulty levels and training objectives.
Solution Approach 2:
The system changes the key parameter of flicker rate from a fixed value to a variable parameter that can be adjusted within a specific range (3-30 Hz). This parameter change enables the vision training device to adapt to different training needs by modifying the flicker frequency, thereby resolving the contradiction between adaptability and complexity.
2Reliability
If the flicker rate is adjusted dynamically, then vision training effectiveness is improved, but the control system becomes more complex
Solution Approach 1:
The patent employs periodic flickering action at controlled frequencies to train vision. The flicker generator creates periodic presentation and non-presentation states of visual content, with the period (frequency) being adjustable between 3-30 Hz. This periodic action with variable frequency enhances training effectiveness while the control architecture manages the associated complexity.
Solution Approach 2:
The system incorporates a receiver that receives indications for adjusting the flicker rate, creating a feedback mechanism. This feedback loop allows the system to respond to training requirements and adjust the flicker rate accordingly, improving vision training effectiveness while the structured feedback system helps manage control complexity.
3Adaptability or versatility
If multiple display areas with different flicker rates are used, then comprehensive vision training is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the display into multiple display areas that can operate with different flicker rates. This segmentation allows different regions of the display to provide different visual training stimuli simultaneously, enabling comprehensive vision training that addresses various visual capabilities. The segmentation principle manages complexity by allowing independent control of each segment's flicker characteristics.
Solution Approach 2:
The display device achieves multi-functionality by enabling different display areas to operate at different flicker rates, allowing a single device to provide multiple types of vision training. This universality enables the system to train various visual functions (central vision, peripheral vision, motion detection) simultaneously, enhancing adaptability while sharing common hardware resources.
