Adaptive Driver Alert System Based on Face Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to notify drivers of potential collisions when the driver's awareness of objects around the vehicle is high, leading to delayed awareness of objects that may collide with the vehicle.
Innovation Solution
An information processing device that includes an external information detection unit, an internal information detection unit, and an output control unit, which determines whether an object detected outside the vehicle is in the same direction as the driver's face and outputs a stronger alert if not, allowing for adaptive notification based on the driver's awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the alarm volume is changed based on the degree of awakening only, then the notification is optimized for drowsy drivers, but no processing is performed when the driver's awakening level is high, leading to delayed awareness of objects
Solution Approach 1:
The system changes the notification parameters (alarm volume, alarm type) based on the driver's awakening level and the relative position of the object. When the driver is highly awakened but the object is in a blind spot, the system switches from no notification to strong notification, adapting the parameter set based on multiple detected conditions rather than a single parameter.
Solution Approach 2:
The system applies different notification strategies to different spatial zones around the vehicle. Objects in the driver's direct view receive different treatment compared to objects in blind spots, even when the driver's awakening level is the same. This local differentiation ensures timely awareness of critical objects while avoiding unnecessary notifications for visible objects.
2Reliability
If strong alerts are always output to ensure driver awareness, then the driver is notified of all objects, but unnecessary alerts increase driver distraction and reduce notification effectiveness
Solution Approach 1:
The notification parameters are dynamically adjusted based on the driver's awakening level and object position. When the driver is highly awakened and the object is in direct view, the system suppresses or reduces notifications. When the driver is drowsy or the object is in a blind spot, the system strengthens the notification. This conditional parameter adjustment eliminates unnecessary alerts while ensuring critical notifications are delivered.
Solution Approach 2:
The system continuously monitors the driver's awakening level and adjusts notification strength accordingly. This feedback mechanism allows the system to learn from the driver's state and optimize notification delivery, reducing distraction while maintaining awareness. The system adapts to the driver's current condition rather than using a fixed notification strategy.

AI summary
An information processing device includes an external information detection unit (141) that detects an object that is present outside a moving body based on data detected by an external detection unit, an internal information detection unit (142) that detects a direction of a driver's face inside the moving body based on data detected by an internal detection unit, a determination unit (155) that determines whether a position of the object detected by the external information detection unit (141) and the direction of the driver's face detected by the internal information detection unit (142) are in a same direction, and an output control unit (105) that outputs an alert to a driver more strongly when the position of the object is not in the same direction as the direction of the driver's face, as compared to a case where the position of the object is in the same direction as the direction of the driver's face.
