Vehicle Traffic Resumption Alert Using Driver Gaze Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often become distracted while stopped at traffic lights or in stop-and-go traffic, leading to delayed reaction times when the traffic resumes, which can cause stress and safety concerns for both the distracted driver and following vehicles.
Innovation Solution
A vehicle system incorporating a collision detection unit and a traffic monitor that uses a camera to track the driver's gaze, providing alerts via audio, visual, and haptic feedback when the driver is not looking forward and traffic in front of the vehicle begins to move.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers check mobile devices or data screens while stopped at traffic lights, then they can access information, but their attention is diverted from the road and reaction time is delayed
Solution Approach 1:
The system continuously monitors driver gaze direction using a camera and provides real-time feedback through alerts when the driver is looking away from the road during stopped traffic conditions. This feedback loop ensures the driver remains attentive without completely preventing information access.
Solution Approach 2:
The system activates gaze tracking and alert mechanisms before the driver potentially becomes distracted, monitoring eye position continuously during stopped traffic conditions to prevent dangerous distraction before it occurs.
2Reliability
If drivers remain stopped while traffic in front moves, then they avoid premature acceleration, but following drivers experience stress and safety concerns
Solution Approach 1:
The system monitors the movement status of vehicles ahead using collision detection units and provides immediate feedback alerts to the stopped driver when traffic begins to move, ensuring timely resumption of driving without premature acceleration.
Solution Approach 2:
The system detects when traffic ahead transitions from stationary to moving and prepares alert signals in advance, notifying the driver before any potential collision risk develops, allowing smooth and safe traffic flow resumption.
3Reliability
If the system provides alerts to distracted drivers, then driver attention is redirected to the road, but the driver may experience startle response and aggressive acceleration
Solution Approach 1:
The system provides gentle reminder alerts at intervals before the driver becomes severely distracted, gradually increasing attention redirection without causing sudden startle responses that could lead to aggressive acceleration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively ensures the driver's attention is redirected to the road, reducing the risk of accidents and stress for other motorists by providing timely alerts when traffic resumes.
Implementation Method 1
tracking, with a camera, a gaze of the driver
Data Source
AI summary
Apparatus and methods are disclosed for a stopped vehicle traffic resumption alert. An example disclosed vehicle includes a collision detection unit and a traffic monitor. The example collision detection unit detects an object in front of the vehicle. The example traffic monitor, when a transmission of the vehicle is in drive and a speed of the vehicle is zero, tracks a gaze of a driver with a camera. Additionally, in response to detecting the object transition from being stationary to moving, and the gaze of the driver not being forward, the traffic monitor provides an alert to the driver.
