Solution Overview

Problem

Existing augmented reality (AR) technologies for vehicle navigation lack intuitive and dynamic guidance, making it difficult for drivers to recognize upcoming driving situations and navigate safely, especially for inexperienced drivers.

Innovation Solution

An AR display device that dynamically changes its interface by separating and joining AR objects to provide real-time navigation information and POI data, reflecting the current driving state and predicted next driving situation, using a processor to render an AR graphic interface that updates based on location and road shape data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If AR driving guidance is displayed at a fixed position, then the display is simple to implement, but the driver cannot intuitively recognize the route guidance and distinguish it from other AR features

Engineering Contradiction:
Improveintuitive recognition of route guidanceVSAvoidAR interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the AR interface by separating the route guidance arrow from other AR features and displaying it at a distinct position (e.g., bottom center or bottom right of the windshield) rather than mixing it with other AR elements. This segmentation allows drivers to intuitively recognize route guidance without confusion from other AR features, while maintaining implementation feasibility through position-based differentiation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If AR route guidance is displayed without dynamic adjustment, then the system is simple to operate, but inexperienced drivers cannot accurately follow the guidance

Engineering Contradiction:
Improvedriving accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustment of the AR route guidance arrow based on the vehicle's current position relative to the target location. The arrow's position, size, or orientation changes dynamically as the vehicle approaches the destination, providing inexperienced drivers with continuous feedback about their progress and improving following accuracy without requiring complex manual adjustments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where the AR guidance arrow provides real-time information about the vehicle's position relative to the intended route and destination. This feedback loop allows drivers to continuously adjust their driving based on the displayed information, improving accuracy especially for inexperienced drivers who need more guidance.

Inventive Principle:
Principle #23Feedback

3Loss of information

If the AR interface displays all information together, then the interface is simple to maintain, but the driver cannot distinguish between current driving state and predicted next situation

Engineering Contradiction:
Improveinformation clarityVSAvoidinterface structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments information display by separating current driving state indicators from predicted next situation indicators within the AR interface. Different visual elements or regions represent different information types, allowing drivers to clearly distinguish between what is happening now and what is predicted to happen, reducing information loss without requiring overly complex interface structures.

Inventive Principle:
Principle #1Segmentation

AI summary

An Augmented Reality (AR) display device 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 display a current driving state of the vehicle while the vehicle is traveling and display a guide related to a predicted next driving situation on a navigation screen using an AR graphic interface. At this time, the AR display device can guide a predicted driving situation in advance by separating and locating a part of the AR graphic interface at a predetermined distance ahead of a predicted location, and allow the separated part of the AR graphic interface to move as the vehicle travels so as to display a guide trajectory along which the vehicle is supposed to travel. This can provide more intuitive and realistic AR guidance to the vehicle.
