Driver Gaze-Based Vehicle Alerts for Multi-Object Warning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warning systems for drivers may issue notifications about multiple objects requiring attention outside the vehicle, causing the driver to feel bothered due to continuous gaze shifts and unnecessary warnings.
Innovation Solution
A notification control device that detects objects requiring attention, sets a field of vision for the driver, and selectively notifies or adjusts recognition judgment times based on the number and type of objects, ensuring the driver is not bothered by unnecessary warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the warning device notifies the driver about each object requiring attention individually, then the driver is informed of all objects, but the driver feels bothered by unnecessary notifications when there are multiple objects
Solution Approach 1:
The patent changes the notification behavior based on the parameter of object count. When multiple objects are detected, the system suppresses notifications even if gaze detection fails, preventing driver disturbance while maintaining safety for critical single-object scenarios
Solution Approach 2:
The notification strategy dynamically adjusts based on the number of detected objects. The system transitions from gaze-based notification for single objects to suppression for multiple objects, optimizing the balance between safety and driver comfort
2Loss of information
If the driver shifts gaze to check multiple objects, then the driver obtains information about object positions, but the driver's gaze may not fix on any one object causing false positive notifications
Solution Approach 1:
The system performs preliminary assessment of the object count before applying gaze detection rules. By detecting multiple objects in advance, the system prepares to suppress notifications, preventing false positives when the driver scans multiple objects without prolonged gaze fixation

AI summary
A notification control device is configured to, when the number of objects requiring attention present in surroundings of a vehicle is less than or equal to a predetermined number, respectively set virtual planes on which the objects are projected at positions of the objects so as to face the vehicle and notify a driver to inform him or her of the presence of an object requiring attention if the field of vision of the driver does not overlap a projected location of the object on the virtual plane during a predetermined period from when detecting that object for greater than or equal to a predetermined recognition judgment time, and, when the number of the objects is larger than the predetermined number, not notify the driver in that way.
