AR Navigation Device Switching 2D and 3D Routes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map and navigation services using augmented reality (AR) face challenges in commercialization due to the need for continuous updates of visual positioning system (VPS) maps, especially in dynamic environments, leading to increased total cost of ownership (TCO) and limited usability indoors or without a global positioning system (GPS).
Innovation Solution
A user equipment and control method that includes an image sensor, display module, communicator, database, and controller to generate and display 2D and 3D route information based on VPS and 2D map information, allowing for indoor/outdoor navigation and continuous map updates through user participation, with features like reward points for high-quality image contributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VPS map information is continuously updated to maintain accuracy in dynamic environments, then navigation reliability is improved, but total cost of ownership increases
Solution Approach 1:
The system enables users to autonomously contribute surrounding images that automatically update VPS map information. The database receives and processes user-submitted images to maintain map accuracy without requiring manual intervention or professional surveying, thereby reducing maintenance costs while ensuring navigation reliability.
Solution Approach 2:
The system implements a feedback mechanism where users provide surrounding images that are processed to update VPS map information. This continuous feedback loop ensures map accuracy is maintained through real-world user experiences, replacing expensive periodic professional updates with ongoing user-contributed data.
2Measurement precision
If AR-based 3D route information is displayed to enhance navigation accuracy, then navigation precision is improved, but device complexity increases
Solution Approach 1:
The display module serves multiple functions: it displays both traditional 2D route information and AR-based 3D route information. The controller automatically selects the appropriate display mode based on environmental conditions and user needs, allowing a single device to handle diverse navigation requirements without requiring separate specialized systems.
Solution Approach 2:
The system dynamically switches between 2D and 3D route information display modes based on real-time conditions. The controller adjusts the display type according to user proximity to destination, environmental factors, and navigation stage, enabling the device to adapt its complexity level to match the immediate navigation needs.
3Ease of operation
If user participation is implemented for map updates to reduce costs, then ease of operation is improved, but information quality control becomes more difficult
Solution Approach 1:
The system replaces manual quality control processes with automated image processing algorithms. The controller automatically analyzes user-submitted surrounding images, extracts relevant features, and integrates them into VPS map information, eliminating the need for manual verification while maintaining consistent quality standards through algorithmic processing.
