Infotainment Display Transitioning for Driver Attentiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-driving and advanced driver-assistance systems, there is a need to dynamically adjust the display of infotainment information to guide the driver's attention towards the external environment when transitioning from autonomous to manual control, ensuring the driver remains aware of their surroundings without distracting them from critical events or hazards.
Innovation Solution
The system renders infotainment information on multiple displays within and outside the vehicle, transitioning the content from an interior display to an external display, such as a heads-up display or a display on another vehicle, using projectors and virtual reality systems, to guide the driver's attention to relevant locations, such as warning alerts or external environments, based on changing vehicle states and operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infotainment information is displayed on interior displays during autonomous operation, then driver engagement with infotainment is improved, but driver attentiveness to the external environment deteriorates
Solution Approach 1:
The system dynamically transitions infotainment display between interior and exterior locations based on vehicle operating mode. During autonomous operation, infotainment is displayed on interior displays to maximize driver engagement. When transitioning to manual control, the system moves infotainment display to exterior surfaces (such as the hood or windshield) so the driver can view it without turning away from the road, thus maintaining both engagement and attentiveness throughout the transition.
Solution Approach 2:
The system uses exterior vehicle surfaces (hood, windshield, windows) as intermediary display surfaces that allow the driver to view infotainment information in the periphery of their field of view. This intermediary approach enables the driver to access infotainment content without completely diverting attention from the external environment, solving the contradiction between engagement and attentiveness.
2Reliability
If infotainment display transitions from interior to exterior surfaces, then driver attentiveness to external environment is improved, but system complexity increases
Solution Approach 1:
The vehicle's exterior surfaces (hood, windshield, windows) serve multiple functions: they act as structural components of the vehicle and simultaneously function as display surfaces for infotainment information. This multi-functionality allows the system to transition displays to exterior surfaces without adding dedicated projection hardware or complex display mechanisms, thereby reducing overall system complexity while improving driver attentiveness.
3Loss of information
If infotainment information is projected onto external surfaces, then driver attention is guided to relevant locations, but distraction from critical events may occur
Solution Approach 1:
The system projects infotainment information to specific localized areas on exterior surfaces (such as the hood or specific windshield regions) rather than distributing it broadly. This localized projection allows the information to be displayed in areas that are naturally part of the driver's peripheral field of view during normal driving, ensuring that the driver notices relevant information without being distracted from critical events or hazards in the main driving field.

AI summary
Various embodiments include systems and methods of displaying visual infotainment information to a vehicle operator. A processor of an infotainment system may provide visual infotainment information to be displayed on a first display when the infotainment system is operating in a first display mode. The processor may determine whether a change in state or operation of the vehicle is within a predetermined threshold variance while the infotainment system is operating in the first display mode. The processor may transition from the first display mode to a second display mode in response to determining that the change in state or operation of the vehicle is within the predetermined threshold variance and provide the visual infotainment information to be displayed on a second display when the infotainment system is operating in the second display mode in a manner configured to guide the operator's attention to an external environment of the vehicle.
