Vehicle Head-Up Display Placement for Passenger Gaze Intersection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle display systems fail to provide relevant information to passengers without disrupting their view of the road traffic, and do not effectively manage information display when multiple passengers are present, as they require the passenger to change their direction of view or do not account for the driver's ability to see road traffic objects.
Innovation Solution
A method and system that detects the direction of view of passengers and drivers, providing information about non-road traffic objects directly in their line of sight using a head-up display or other projection technologies, allowing for adaptive display placement and content based on individual or intersecting views, and utilizing position detection, object detection, and eye-tracking systems integrated with the vehicle or external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed in the passenger's field of view, then information delivery to passengers is improved, but driver distraction and road safety may deteriorate
Solution Approach 1:
The system segments the vehicle occupants into different groups (driver vs. passengers) and provides tailored information displays for each group. The driver receives only road traffic relevant information, while passengers receive information about landscape objects, ensuring that passenger information delivery does not distract the driver.
Solution Approach 2:
The system applies different display qualities and information types to different spatial locations and user roles. Information displays are localized to specific fields of view - the driver's FOV receives traffic-critical information while the passenger's FOV receives landscape information, creating locally optimized display quality for each user.
2Adaptability or versatility
If a single display system serves all occupants, then device complexity is reduced, but adaptability to different occupants' needs deteriorates
Solution Approach 1:
The display system is designed with multi-functionality to serve both driver and passenger needs through a single integrated system. The same display infrastructure can dynamically switch between providing traffic information to the driver and landscape information to passengers, eliminating the need for separate display systems while maintaining high adaptability.
Solution Approach 2:
The system dynamically adjusts display content, position, and characteristics based on real-time detection of occupant directions of view and identification of their roles. This dynamic adaptation allows a single display system to provide personalized information to different occupants without requiring multiple fixed display systems.
3Loss of information
If the driver is provided with information about objects they cannot see, then information completeness is improved, but driver attention and focus may deteriorate
Solution Approach 1:
The system applies partial action by selectively providing information to the driver only when necessary - specifically when the driver cannot see road traffic objects themselves. The system avoids excessive information provision by filtering out non-critical landscape information from the driver's display, maintaining attention management while ensuring completeness of critical traffic information.
4Adaptability or versatility
If multiple separate display systems are used for different passengers, then information personalization is improved, but device complexity and cost deteriorate
Solution Approach 1:
The system merges multiple display functions into a single integrated display system that can simultaneously or sequentially serve multiple passengers with personalized information. By combining the display infrastructure while maintaining independent content control for each passenger based on their direction of view, the system achieves information personalization without the complexity and cost of multiple separate display systems.

AI summary
A method includes detecting a direction of view of at least one passenger as an occupant of the motor vehicle; and providing a display with information about at least one object in a landscape of the motor vehicle viewed by the at least one passenger, the at least one object not being relevant to road traffic, such that said information is provided in an area in the direction of view of the at least one passenger, wherein, when multiple passengers of the motor vehicle are detected, a direction of view of each passenger is detected, such that a display with information about the at least one object in the landscape of the motor vehicle viewed by at least two passengers is provided in an area in which the direction of view of the at least two passengers intersect.
