Vehicle Display Layout Using Gaze Detection to Prevent Information Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems hinder driver information perception by overwhelming the driver with multiple items of information, making it difficult to focus on essential data without distracting from driving.
Innovation Solution
A display device that determines the driver's viewing direction and adjusts the display by enlarging or adding relevant information, allowing primary information to be displayed prominently, and optionally includes a second electro-optical display on the A-pillar for environmental awareness, with voice output and gaze gesture control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple items of information are displayed on the electro-optical display, then the information completeness is improved, but the driver's ability to grasp essential information deteriorates due to information overload
Solution Approach 1:
The display information is segmented into multiple hierarchical levels. The first level shows essential information (speed, steering angle, gear position), while secondary information (fuel level, temperature, range) is displayed only when the driver requests it through specific gestures or voice commands. This segmentation resolves the contradiction by organizing information completeness across different display states rather than showing all information simultaneously.
Solution Approach 2:
The display system dynamically adjusts its content based on driver input and vehicle state. Information transitions between hidden, partially displayed, and fully displayed states depending on driver gestures, voice commands, or automatic detection of driving conditions. This dynamic behavior allows the system to maintain information completeness while adapting to the driver's immediate needs, preventing information overload.
2Loss of information
If the driver changes head position to see hidden information, then the information accessibility is improved, but the driving safety deteriorates due to increased distraction
Solution Approach 1:
Voice recognition and gesture detection systems serve as intermediaries between the driver and the display system. Instead of requiring physical head movement to access information, the driver can use voice commands or hand gestures to request specific information layers. This intermediary interface allows information accessibility while maintaining driving safety by keeping the driver's head in the optimal driving position.
Solution Approach 2:
The mechanical action of moving the head to see different display areas is replaced with voice commands and gesture-based controls. The system substitutes physical head movement with alternative control mechanisms that allow information access without compromising driving posture or safety.
3Loss of information
If additional information is displayed on a second electro-optical display on the A-pillar, then the situational awareness is improved, but the device complexity increases
Solution Approach 1:
The display system is segmented across two physical locations: the main dashboard display and the A-pillar display. Each display handles specific types of information - the main display shows vehicle operation parameters while the A-pillar display shows environmental information. This spatial segmentation improves situational awareness by distributing information across multiple locations while managing overall system complexity through functional division.
Solution Approach 2:
The second electro-optical display on the A-pillar serves multiple functions: displaying environmental information, providing additional vehicle parameters, and offering an alternative information channel that reduces the load on the main display. This multi-functionality justifies the increased device complexity by providing comprehensive situational awareness through a single additional component.

AI summary
A display device for a vehicle, comprising an electro-optical display and a position detection device which is used to determine the position of eyes of a driver of the vehicle, wherein a multiplicity of different items of information are displayed by the electro-optical display device and are perceived by the driver of the vehicle is disclosed. Provision is made for there to be a viewing direction detector for determining the driver's viewing direction, which is used to determine which information of the multiplicity of different items of information are perceived by the driver, and, depending on the perceived information, for the perceived information to be able to be enlarged and/or for additional information relating to the perceived information to be able to be displayed. A method for displaying information on a display device in a vehicle is also disclosed.
