Stereoscopic Game System for Binocular Dysfunction Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Binocular dysfunctions, such as convergence insufficiency, are inadequately addressed by traditional vision therapy methods, which often result in patient boredom and insufficient treatment due to lack of engagement and resource constraints, leading to unresolved visual symptoms in individuals, including double vision, eyestrain, and headaches.
Innovation Solution
A 3D game using a head-mounted display that controls eye movement through stereoscopic effects, optimizing vergence eye movements by rendering visual stimuli that stimulate disparity vergence while minimizing accommodative cues, and dynamically adjusting visual stimuli based on eye position and velocity to improve binocular coordination and reduce visual suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vision therapy methods are used to treat binocular dysfunctions, then treatment protocols can be established, but patient boredom and lack of compliance occur due to repetitive patterns
Solution Approach 1:
The patent applies dynamics by transforming static, repetitive vision therapy exercises into dynamic, game-based activities. The system uses real-time eye tracking to dynamically adjust game elements, targets, and challenges based on patient performance, making the therapy adaptive and engaging rather than monotonous and static.
Solution Approach 2:
The patent replaces traditional mechanical vision therapy apparatus with a computer-based system that uses software-rendered visual stimuli and eye tracking technology. This substitution enables more flexible, interactive, and visually appealing therapy protocols that can adapt to patient responses without physical constraints.
2Reliability
If extensive vision therapy sessions are provided to remediate vision symptoms, then treatment outcomes can be improved, but resource constraints and insurance coverage limitations arise
Solution Approach 1:
The patent enables self-service by allowing patients to perform vision therapy at home using the head-mounted display and eye tracking system. The automated eye tracking and adaptive game protocols eliminate the need for constant therapist supervision, enabling patients to complete therapy sessions independently and increasing overall treatment availability.
Solution Approach 2:
The patent creates a universal therapy platform that can address multiple binocular dysfunction types (convergence insufficiency, divergence insufficiency, strabismus) through a single system. The eye tracking data and adaptive algorithms can be configured to treat various conditions, making the system versatile and cost-effective for diverse patient needs.
3Reliability
If repetitive eye motion patterns are used in vision therapy, then binocular coordination can be improved, but patient engagement decreases leading to insufficient treatment
Solution Approach 1:
The patent implements periodic action through game-based therapy sessions that incorporate varying challenges, targets, and feedback intervals. The eye tracking system periodically assesses patient performance and adjusts difficulty levels, creating a rhythm of challenge and achievement that maintains engagement throughout the therapy session.
Solution Approach 2:
The patent incorporates real-time feedback through the eye tracking system, which continuously monitors eye position, convergence, and divergence. This feedback is immediately translated into game responses, target adjustments, and performance metrics, keeping patients informed and motivated throughout the therapy session.
