Gaze-Adaptive Vehicle Display System for Driver Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to ensure that drivers consciously notice important information and have sufficient time to process it without being distracted, and they often disturb other occupants with irrelevant messages.
Innovation Solution
Implementing a display system that uses gaze tracking to delay the appearance of messages until the driver is focused on the display, and reappear when the driver looks back, ensuring the message is seen when attention is available and avoiding distraction from critical tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If messages are displayed for a fixed period regardless of driver attention, then the driver is informed of important information, but the driver may be distracted from critical tasks or other occupants are disturbed by irrelevant messages
Solution Approach 1:
The display system dynamically adjusts message visibility based on real-time detection of driver attention state. Messages are displayed only when the driver is determined to be attentive, and hidden when distraction is detected, creating a dynamic adaptation to changing operational conditions rather than a static fixed-duration display approach
Solution Approach 2:
The system continuously monitors driver state through sensors (eye tracking, head position, steering behavior) and uses this feedback to control message display. The display state is adjusted based on feedback about whether the driver is currently attentive or distracted, creating a closed-loop control system that prevents harmful distraction while ensuring information delivery
2Loss of time
If messages are displayed immediately when determined relevant, then the driver receives timely information, but the driver may not have sufficient conscious attention to process the information safely
Solution Approach 1:
The system performs preliminary assessment of driver attention state before initiating message display. By evaluating whether the driver is currently attentive through sensor data analysis, the system ensures that information is only presented when the driver is in a safe state to process it consciously, preventing premature display during critical driving moments
3Ease of operation
If gaze tracking and attention detection systems are implemented, then message display can be optimized for driver attention, but the device complexity increases
Solution Approach 1:
The system uses multi-functional sensors that serve both primary driving assistance functions and secondary attention detection functions. For example, cameras and sensors used for driver monitoring and collision avoidance are also utilized to detect gaze direction and attention state, eliminating the need for separate dedicated attention detection hardware and reducing overall system complexity

AI summary
The invention relates to user interfaces, a computer program product, a signal sequence, a means of locomotion and a method for displaying information (5) on a display device (4) of a means of locomotion (10). The method comprises the following steps: - determining an information to be displayed, - determining that a user (1) sees the display device (4) and in response thereto, - displaying a message (5) representing the information on the display device (4). Alternatively, it is proposed, in response to the display of the message (5) on the display device, to determine that the user (1) looks away from the display device (4) and in response thereto to hide the message (5).
