Eye Movement Biosensor for Vehicle Safety Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively address vertigo, motion sickness, and spatial disorientation in motion-provocative environments, leading to compromised human performance and potential loss of control in vehicles or equipment.
Innovation Solution
A physiologic biosensor system that monitors abnormal eye movements and physiological responses to trigger a controller response, altering vehicle or equipment operations to a safe mode and providing alarms to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physiologic biosensor system is implemented to monitor eye movements and physiological responses, then safety and accident prevention are improved, but device complexity increases
Solution Approach 1:
The system divides the monitoring function into separate modular components: eye movement sensors, physiological response sensors, processing units, and control interfaces. Each module performs a specific function, making the overall complex system manageable and maintainable while achieving comprehensive safety monitoring
Solution Approach 2:
The biosensor system is designed to monitor multiple physiological parameters (eye movements, heart rate, respiration, skin conductance) simultaneously using a single integrated platform, reducing the need for multiple separate systems and minimizing overall device complexity while maximizing safety coverage
2Reliability
If automatic controller response is implemented to alter vehicle operations, then loss of control is prevented, but ease of operation deteriorates
Solution Approach 1:
The system pre-programs safe mode operations and control responses in advance, so when physiological abnormalities are detected, the controller can immediately execute pre-planned corrective actions without requiring complex real-time decision-making, maintaining ease of operation while preventing loss of control
Solution Approach 2:
The system continuously monitors operator physiological state and provides feedback to the controller, which automatically adjusts vehicle operations in response. This closed-loop feedback mechanism enables automatic safety interventions while maintaining simple operator interaction through intuitive interfaces that require minimal input

AI summary
A head-mounted video-camera-based eye sensor system and method for measuring palpebral movement is disclosed. The system and method comprise a display that includes at least one display element responsive to palpebral movement information from the eye sensor. The system and method also comprise an electronic interface to a vehicle or powered equipment to transmit the palpebral movement information to the vehicle or powered equipment. The system and method can be used to alert the user, the vehicle, and/or the powered equipment to the fact that a person might be experiencing vertigo, motion sickness, motion intolerance, and/or spatial disorientation.
