Adaptive Vehicle Navigation Guidance for Driver Confusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to effectively suppress driver confusion during navigation, which can lead to incorrect decisions and operations.
Innovation Solution
A navigation system utilizing machine learning models to generate and adjust navigation and transmission information based on driver reactions, personal information, and real-time feedback to minimize confusion through optimized voice and image guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation information is provided to the driver, then the driver can reach the destination, but the driver may get confused by the navigation instructions
Solution Approach 1:
The system monitors driver reactions (gaze direction, head pose, voice commands) in real-time and uses this feedback to detect confusion states. When confusion is detected, the system dynamically adjusts navigation information presentation, such as simplifying instructions or providing additional guidance, thereby resolving the contradiction between providing necessary navigation information and avoiding driver confusion
Solution Approach 2:
The navigation system transitions from static, fixed navigation instructions to dynamic, adaptive information presentation. The system continuously adjusts the complexity, timing, and modality of navigation information based on real-time driver state assessment, allowing the same navigation system to adapt to different driver cognitive loads and attention levels throughout the journey
2Ease of operation
If navigation information is simplified to reduce confusion, then driver understanding improves, but navigation precision may be compromised
Solution Approach 1:
The system provides navigation information in graduated levels of detail based on driver confusion assessment. When confusion is detected, the system delivers more detailed and explicit instructions (excessive action) to ensure understanding. When the driver is clearly understanding, the system provides concise instructions (partial action), thereby maintaining precision while adapting to driver needs in real-time

AI summary
A navigation system generates navigation information used for providing navigation to a driver of a vehicle based on current position of the vehicle, map information, and destination information indicating a destination of the vehicle, generates transmission information which is information to be communicated to the driver via a user interface based on the navigation information, and determines whether there has been confusion in any of recognition, decision, and operation of the driver with respect to the transmission information communicated from the user interface to the driver based on reaction of the driver to the transmission information. The transmission information or the navigation information is generated so that the confusion is suppressed based on the transmission information communicated to the driver via the user interface and the reaction of the driver to the transmission information when it is determined that there has been the confusion.
