Vehicle AR Signage Rendering for Driver Distraction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AR technologies in vehicles struggle to provide high-realism AR digital signage while ensuring the driver maintains their focus on the road by adapting display based on situational factors such as road conditions, traffic, and personal preferences.
Innovation Solution
An AR signage display apparatus that adjusts AR digital signage display based on vehicle traveling information and environmental data, restricting or modifying the display in real-time to ensure the driver's attention is maintained on the road, using a processor to correct signage data based on conditions like turning, specific sections, and navigation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If AR digital signage is displayed with high realism in the driver's viewing field, then information presentation quality is improved, but driver safety may be compromised due to distraction
Solution Approach 1:
The system dynamically adjusts AR signage display based on real-time driving conditions, vehicle state, and environmental factors. The processor continuously monitors situational parameters and modifies signage visibility, position, and content accordingly, transforming the display from static to adaptive to resolve the contradiction between information quality and driver safety
Solution Approach 2:
The system applies different display strategies to different spatial regions and situational contexts. Rather than uniformly displaying or hiding all AR signage, it selectively adjusts display parameters in specific viewing fields and under specific conditions, allowing high-realism display in safe contexts while restricting display when safety concerns arise
2Loss of information
If multiple pieces of information are presented simultaneously through AR objects, then information completeness is improved, but driver cognitive load increases
Solution Approach 1:
The system implements selective information presentation by displaying only the most relevant AR signage based on current driving context, vehicle state, and environmental factors. Rather than presenting all available information simultaneously, it filters and prioritizes content to maintain information completeness while preventing cognitive overload
Solution Approach 2:
The system segments information presentation into priority levels and temporal sequences. Critical safety-related AR signage is displayed prominently, while less urgent information is either omitted or presented in a staged manner, dividing the information load to reduce cognitive demand while maintaining overall information completeness
3Object-affected harmful factors
If AR signage display is restricted based on various situational factors, then driver safety is improved, but information accessibility deteriorates
Solution Approach 1:
The system implements continuous feedback loops where the processor monitors driving conditions, vehicle state, and environmental parameters, then adjusts AR signage display accordingly. This closed-loop control ensures that display restrictions are applied only when necessary for safety, while automatically restoring full information accessibility when conditions improve, thus resolving the contradiction between safety and information access
Data Source
AI summary
An AR signage display device linked with a vehicle and an operation method thereof are disclosed. An AR signage display device linked with a vehicle according to the present invention may determine whether a condition to limit display of AR digital signage has occurred, on the basis of traveling information of a vehicle and map information, which are received while the vehicle is traveling, and if the condition has occurred, correct signage data matching a position where the condition to limit display has occurred and perform AR rendering. Accordingly, when a vehicle turns, frequently changes traveling, or enters a particular zone such as a roundabout, the device may not display partial AR digital signage or limit display thereof so that a driver can focus on driving on the basis of such traveling information.
