Adaptive Orthoptic System for Binocular Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for alleviating stereo deficiency, such as orthoptics, primarily rely on eye-training exercises that may not effectively improve visual function by merely reducing suppression, and do not adequately address the need for enhanced depth perception in individuals with binocular vision disorders like strabismus and aniseikonia.
Innovation Solution
An orthoptic method and system that displays stereoscopic objects with both monocular and binocular depth cues, titrating the strength of monocular cues based on individual performance to reduce dependence on them and enhance binocular depth perception, using a user interface and processor to adjust cue strength and provide feedback on progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If monocular depth cues are used to assist depth perception tasks, then ease of operation is improved, but binocular depth perception improvement is hindered
Solution Approach 1:
The system dynamically adjusts the strength of monocular depth cues based on the individual's performance level. During training, monocular cues are initially strong to facilitate task completion, then gradually weakened as performance improves, forcing greater reliance on binocular cues. This dynamic adjustment resolves the contradiction by making the system adaptive rather than static.
Solution Approach 2:
The system changes the parameter of monocular cue strength during the training process. By systematically reducing the strength of monocular cues (such as motion parallax, relative size, and perspective) while maintaining binocular disparity cues, the system transitions the user from relying on monocular cues to developing genuine binocular depth perception, thus resolving the contradiction between ease of operation and reliability of improvement.
2Reliability
If suppression is reduced through dichoptic training, then binocular vision function is improved, but visual function improvement does not necessarily correlate
Solution Approach 1:
The system incorporates performance monitoring and feedback mechanisms that track the individual's depth perception accuracy. This feedback is used to adjust training parameters in real-time, ensuring that suppression reduction actually translates to functional improvement. The system can identify when suppression reduction is occurring without corresponding functional gain and adjust the training approach accordingly.
Solution Approach 2:
The training program is designed to automatically adapt to the individual's needs based on their performance, reducing the need for constant external adjustment. The system self-regulates the training intensity and cue strength based on measured performance, ensuring that suppression reduction is optimally converted into functional visual improvement.
3Reliability
If monocular depth cue strength is reduced during training, then binocular depth perception is enhanced, but task difficulty increases
Solution Approach 1:
The system dynamically balances task difficulty by adjusting monocular cue strength based on real-time performance monitoring. When performance drops below a threshold, the system increases monocular cue strength to maintain engagement and prevent frustration. When performance exceeds the threshold, it reduces monocular cue strength to continue enhancing binocular perception. This dynamic balancing resolves the contradiction between enhancing binocular perception and maintaining task accessibility.
