AR Route Guidance With Node- and Link-Specific Navigation Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) navigation systems provide only basic turn-by-turn direction guidance, lacking additional information relevant to nodes and links in a route, leading to insufficient user experience.
Innovation Solution
A route guidance method that augments and displays content related to predetermined information at nodes and links within an AR view, providing detailed guidance information such as direction indicators, actions to be taken, and real-time updates based on user interaction and peripheral conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If basic turn-by-turn direction guidance is provided through AR view, then the navigation system is simple and easy to operate, but the information provided is insufficient and user experience is poor
Solution Approach 1:
The patent segments guidance information into different types (direction indicators, action instructions, node-specific information, link-specific information) and presents them separately in the AR view. This allows comprehensive information provision while maintaining clear organization and avoiding overwhelming the user with undifferentiated data.
Solution Approach 2:
The patent applies local quality by providing specific types of information at different locations in the route. Node-specific information (e.g., building entries, exits, elevators) is displayed when approaching nodes, while link-specific information (e.g., distance, time, route attributes) is displayed along the path between nodes. This ensures relevant information is provided contextually without cluttering the entire interface.
2Adaptability or versatility
If detailed guidance information is provided at nodes and links, then user experience is improved, but the processing and display complexity increases
Solution Approach 1:
The patent uses preliminary action by pre-registering specific information with each node and link in advance. This allows the system to efficiently retrieve and display relevant information when the user approaches or is at a particular node or link, without requiring complex real-time processing decisions. The information is prepared beforehand and triggered by the user's location and interaction state.
Solution Approach 2:
The patent implements feedback mechanisms where the system monitors user interactions (e.g., approaching nodes, reaching destinations, deviating from route) and dynamically adjusts the displayed guidance information. This feedback loop ensures the information provided is always relevant to the user's current situation, improving adaptability while maintaining manageable complexity through rule-based responses.
3Measurement precision
If real-time information updates are provided based on user interaction, then the guidance accuracy is improved, but the computational requirements and system complexity increase
Solution Approach 1:
The patent applies self-service by using the user terminal's existing sensors and cameras to automatically detect user location, movement direction, and surrounding environment. The system processes this self-collected data to update guidance information in real-time without requiring external infrastructure or complex centralized processing, thereby improving precision while limiting complexity growth.

AI summary
A method of obtaining a route from a point of departure to a destination includes providing route guidance through an augmented reality (AR) view including an image captured by a camera. To provide route guidance, as a user terminal moves toward a destination on the basis of an obtained route, when an interaction occurs between the user terminal and a node or a link in which predetermined information included in the route is registered, content associated with the predetermined information is augmented and displayed as guidance information on an image of an AR view.
