Vehicle AR Display Interface for Predictive Driving Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) driving guidance technologies struggle to provide intuitive and comprehensive route guidance, particularly in diverse driving situations, due to limitations in distinguishing AR images from other features and relying solely on sensing data and navigation information, which can lead to difficulties for inexperienced drivers and limited situational awareness.
Innovation Solution
An AR display device that predicts potential driving situations by considering external network data in addition to map and sensing data, using separable and deformable AR objects to provide intuitive guidance, notifications, and action recommendations, and quickly displaying information related to parking or charging through real-time updates of an AR graphic interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing AR driving guidance displays direction change guidance at a fixed position, then the AR image is displayed, but it becomes difficult to distinguish the AR image from other AR features and provides limited intuitive route guidance
Solution Approach 1:
The AR guidance system segments route guidance information into multiple dynamic elements including current location indicators, direction change arrows, distance markers, and turn-by-turn instructions that are spatially distributed across the windshield display area, allowing drivers to easily distinguish and comprehend different guidance components
Solution Approach 2:
The AR guidance elements dynamically adjust their position, size, and orientation based on the vehicle's current state, upcoming maneuvers, and driver perspective. Direction change arrows rotate and scale to indicate turn intensity, while distance markers move to reflect remaining distance, making the guidance more intuitive and easier to understand
2Adaptability or versatility
If AR driving guidance relies only on sensing data and navigation information, then the system is simple, but it cannot display various driving situations and provide comprehensive guidance
Solution Approach 1:
The AR display system integrates multiple data sources including sensing data from vehicle sensors, navigation information from GPS, real-time traffic data from network connections, and map data from geographic databases. This multi-functional data integration allows the system to handle diverse driving situations such as route guidance, traffic condition display, parking assistance, and charging station location while maintaining a unified display interface
Solution Approach 2:
The system employs an intermediary processing layer that aggregates and harmonizes data from multiple sources before presenting it to the driver. This intermediary layer filters, prioritizes, and formats information from sensors, navigation systems, and network data into coherent AR visual elements, managing complexity while providing comprehensive situational awareness
3Measurement precision
If AR guidance provides detailed information for inexperienced drivers, then driving accuracy improves, but the guidance becomes less intuitive and more complex to process
Solution Approach 1:
The AR guidance system applies different levels of information detail to different spatial zones and guidance contexts. Critical information such as immediate turn directions and distance to next maneuver are displayed with high prominence and simplicity, while less critical information is displayed with lower prominence. The system adapts the level of detail based on the driver's current needs and upcoming maneuvers, maintaining intuitiveness while providing necessary precision

AI summary
An Augmented Reality, AR, display device (800) interoperating with a vehicle and a method for operating the same are disclosed. An AR display device interoperating with a vehicle according to the present disclosure can predict a context in which a problem may occur by additionally considering an external resource in addition to map data and sensing data as internal resources while the vehicle travels, and display the predicted context by changing an AR graphic interface in real time, thereby intuitively notifying a driver of the predicted context and a countermeasure therefor. At this time, an AR object separated from the AR graphic interface not only displays a guide for the predicted context but also provides a corresponding guide for safe driving in the predicted context.
