In-Vehicle Object Display Using Eye-Tracked Field-of-View Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle display technologies do not effectively assist occupants in intuitively accessing information about their surroundings, particularly in autonomous driving scenarios where the driver may not be actively engaged with the road traffic objects.
Innovation Solution
A method and system that determine the vehicle's position, detect relevant and non-relevant road traffic objects, and the occupants' viewing directions to provide intuitive displays of information directly within the occupants' field of view using a combination of GPS, cameras, LIDAR, eye-tracking systems, and head-up displays, ensuring that both drivers and passengers receive relevant information without needing to change their gaze.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on separate display devices or head-up displays, then information accessibility is improved, but the driver's attention may be distracted from the road
Solution Approach 1:
The system displays information locally at the exact position of the object in the driver's field of view rather than on a separate display device. This allows the driver to see both the road and the information simultaneously without moving their gaze, thus improving information accessibility while preventing distraction from the road.
2Loss of information
If the driver's viewing direction is monitored to provide information, then information relevance is improved, but system complexity increases
Solution Approach 1:
The system uses the existing camera and processor components of the autonomous driving system for multiple purposes: both for navigating functions and for detecting objects and providing information based on the driver's viewing direction. This multi-functionality approach improves information relevance while minimizing additional system complexity.
3Measurement precision
If multiple detection systems are used to determine viewing direction and object positions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system combines the camera and processor from the autonomous driving navigation system with eye-tracking technology to create an integrated detection system. This merging approach allows for precise viewing direction detection and object position tracking while avoiding the complexity of completely separate detection systems.

Function Achieved in This Case
This solution enables intuitive and efficient information delivery to vehicle occupants, ensuring they remain aware of their surroundings, even if the driver is not actively looking at road traffic objects, enhancing safety and awareness in autonomous driving environments.
Implementation Method 1
A method and system that determine the vehicle's position, detect relevant and non-relevant road traffic objects, and the occupants' viewing directions to provide intuitive displays of information directly within the occupants' field of view using a combination of GPS, cameras, LIDAR, eye-tracking systems, and head-up displays
Implementation Method 2

AI summary
The invention relates to a method for providing a display in a motor vehicle, having the steps: a) determining the position of the motor vehicle; b) identifying at least one object (20, 24), in particular in the surroundings of the motor vehicle, depending on the determined position; c) sensing the viewing direction of at least one occupant of the motor vehicle; and d) providing a display (22, 26) with information about the at least one object (20, 24) such that it is provided in the field of view, defined by the viewing direction, of the occupant.
