Driver Tunnel Vision Detection and Attention Redirection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicle drivers often develop tunnel vision in dangerous situations, leading to a high probability of collision due to a fixed gaze that prevents perception of avoidance lanes or paths.
Innovation Solution
A method and device that detect the driver's viewing direction, compare it with previous directions to identify a lack of change or angular range, and stimulate the driver with visual or other sensory cues to avoid tunnel vision, potentially aided by predictive safety systems to suggest collision-free paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver focuses intensely on the immediate danger area, then the driver's attention is concentrated on the threat, but the driver's field of vision narrows to the point of missing alternative escape paths
Solution Approach 1:
The system transitions the driver's attention from a two-dimensional focal point (the immediate danger) to a three-dimensional spatial awareness by projecting visual cues along alternative escape paths and stimulating peripheral vision, thereby expanding the effective field of vision while maintaining focus on the threat
Solution Approach 2:
The system introduces intermediary visual cues and stimulation devices that act as mediators between the driver's focused attention and the peripheral escape paths, guiding attention expansion without disrupting the concentration on the immediate danger
2Reliability
If the driver maintains a fixed gaze on the danger, then the driver's reaction is focused, but the driver fails to perceive avoidance lanes or paths
Solution Approach 1:
The system implements periodic scanning of the driver's eye movements and alternating stimulation patterns that rhythmically guide attention between the central danger focus and peripheral escape paths, ensuring continuous perception of avoidance options while maintaining reaction focus
Solution Approach 2:
The system uses real-time feedback from eye tracking cameras and driver monitoring to dynamically adjust stimulation patterns, providing corrective feedback when tunnel vision is detected and guiding the driver's gaze toward alternative paths while preserving the focused reaction to the threat
3Reliability
If visual stimulation is used to interrupt tunnel vision, then the driver's sensory organs are directly addressed, but additional system complexity is introduced
Solution Approach 1:
The system integrates multiple functions into existing vehicle components - the head-up display serves both navigation and tunnel vision interruption, the camera system performs both driver monitoring and gaze tracking, and the audio system provides both entertainment and emergency alerts, thereby reducing overall system complexity while maintaining high reliability

AI summary
A method for avoiding a tunnel vision of a motor vehicle driver includes detecting an instantaneous viewing direction of the driver; comparing the instantaneous viewing direction with at least one previous viewing direction; detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached; and stimulating the motor vehicle driver to avoid the tunnel vision. A device for avoiding a tunnel vision of the driver includes a camera for detecting an instantaneous viewing direction of the motor vehicle driver; a control unit for comparing the instantaneous viewing direction with at least one previous viewing direction and for detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached, and a device for stimulating the motor vehicle driver to avoid the tunnel vision.
