Solution Overview
Problem
Conventional ride-hailing services face challenges in providing accurate and user-friendly navigation instructions, especially in enhancing visual aids and intuitive route visualizations for users to find pick-up locations and safely reach their destinations.
Innovation Solution
The implementation of augmented reality (AR) navigation guidance on mobile devices, utilizing a combination of GPS, LiDAR maps, and sensor data to provide precise location and orientation tracking, enabling the superimposition of visual cues such as animated graphics and virtual objects onto camera feeds for navigation assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional map-based navigation is used, then the system is simple to implement, but the user experience lacks intuitiveness and visual engagement
Solution Approach 1:
The patent replaces conventional 2D map-based navigation with augmented reality visualization that overlays navigation cues directly onto the user's camera view. This substitution transforms abstract map data into intuitive visual overlays showing pick-up locations, drop-off points, and route directions in the real-world context, dramatically improving user experience while accepting increased system complexity through integration of camera, GPS, and AR rendering components.
2Loss of information
If AR navigation guidance is implemented, then navigation intuitiveness and user experience are improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent segments navigation information into distinct AR overlay elements including pick-up location markers, drop-off point indicators, route direction arrows, and distance markers. Each element is independently rendered and positioned based on GPS data and camera orientation, allowing complex navigation information to be presented in manageable, intuitively understood visual components without overwhelming the user or the system.
Solution Approach 2:
The patent introduces an intermediary processing layer that translates GPS coordinates and camera feed data into AR overlay positions and orientations. This mediator component processes location information, determines device orientation relative to the route, and renders appropriate visual cues at correct positions in the camera view, thereby managing system complexity through modular information transformation.
3Measurement precision
If precise location tracking using GPS and LiDAR is used, then navigation accuracy is improved, but energy consumption and processing load increase
Solution Approach 1:
The patent implements periodic location updates rather than continuous high-precision tracking, updating AR overlay positions at appropriate intervals based on user movement and route progress. This periodic action maintains navigation accuracy by refreshing location data when meaningful changes occur, while reducing energy consumption by avoiding constant high-frequency GPS and LiDAR operations.

Implementation Method 1
A location of the mobile device is determined, based on sensor data from the mobile device and an image stream received from a camera of the mobile device
Implementation Method 2
comparing the image stream to a known map to determine a precise location of the mobile device
Implementation Method 3
AR guidance is provided on a mobile device by superimposing visual cues onto an image stream received on the mobile device, such as a camera image
