Vehicle Content Display Eye-Gaze Timer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle camera systems allow drivers to view monitored content at all times, leading to potential distraction and increased accident risk, as they are not restricted to specific activation conditions like rear view cameras.
Innovation Solution
A safety system that monitors a driver's eye-gaze to control the timing of vehicle monitored content display, starting a timer when the driver looks at the content and resetting it when they focus on the road, preventing excessive distraction by disabling the content if the driver looks at it for too long without re-focusing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle monitored content is made available at all times, then driver awareness is improved, but driver distraction increases
Solution Approach 1:
The system dynamically adjusts the availability of vehicle monitored content based on real-time driver behavior. A timer mechanism monitors how long the driver has been viewing the content, and when the driver looks away from the display (indicating return to road focus), the timer resets. This dynamic control allows the system to adapt content availability to the driver's current attention state, preventing excessive distraction while maintaining awareness benefits.
2Loss of information
If driver can continuously view vehicle monitored content, then situational awareness is improved, but road focus deteriorates
Solution Approach 1:
The system implements a feedback mechanism where the driver's viewing behavior directly controls content availability. When the driver looks away from the display, the timer resets, providing immediate feedback that encourages return to road focus. This feedback loop creates a self-regulating system that balances information consumption with safe driving practices, ensuring the driver maintains adequate road focus while still accessing situational awareness information.

AI summary
In one embodiment, a safety system for playing vehicle monitored content in a vehicle while minimizing driver distraction is provided. When the driver selects a camera, such as a rear view camera, vehicle monitored content stream from the camera is displayed on a display in the vehicle. While the driver drives the vehicle, the eye-gaze of the driver is monitored. When the eye-gaze of the driver shows that the driver is looking at the display, a timer is started. The timer runs when the driver looks at the display. When the eye-gaze of the driver shows that the driver has looked at the road continuously for more than a threshold amount of time, the time associated with the vehicle monitored content is reset back to its initial value. If the timer runs out, indicating that the driver has been watching the vehicle monitored content too much without also looking at the road, the vehicle monitored content is stopped and the driver is prevented from watching the vehicle monitored content for some period of time.
