Route Verification in Mobile Navigation via Positional Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems in portable terminals struggle to accurately share and verify positional information between users, making it difficult for one user to determine if another user is following the correct route to a destination, especially when one user is already at the destination and the other is en route.
Innovation Solution
An apparatus and method that establishes a call connection between portable terminals to exchange positional information, using a controller, route analyzing unit, and displaying unit to provide route information, with the option of augmented reality for route verification, allowing users to share their positions and determine the best route to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If navigation function provides route based on position, then user can reach approximate location of destination, but user has difficulty in finding exact point where other party is located
Solution Approach 1:
The patent creates a virtual copy of the real-world route environment by generating a route map image that replicates the actual route from departure to destination. This virtual copy includes visual markers for the user's current position and the other party's location, allowing the user to verify their position against the copied route representation without needing to physically search for landmarks or ask for directions.
2Loss of information
If navigation function provides route based on position, then route information is provided, but one user located at destination and the other user moving to destination cannot verify a route and the positional information for each other
Solution Approach 1:
The system implements feedback by continuously capturing the user's current position via GPS, comparing it against the pre-generated route map image, and providing real-time visual feedback showing whether the user is on the correct route. The system also provides feedback to the other party at the destination, allowing them to verify the user's approach and provide guidance if the user deviates from the route.
Solution Approach 2:
The patent introduces a server as an intermediary that facilitates information exchange between the user en route and the other party at the destination. The server receives route information from the destination, generates the route map image, and transmits it to the user's terminal. This intermediary enables reliable positional information sharing and route verification that would be difficult to achieve through direct peer-to-peer communication alone.
3Ease of operation
If conventional navigation is used, then basic route guidance is provided, but users cannot confirm if the other party moves along an exact route
Solution Approach 1:
The patent adds a visual dimension to route verification by generating and displaying a route map image that shows the geographical layout of the route. Instead of relying solely on one-dimensional turn-by-turn instructions, the system provides a two-dimensional visual representation that allows users to see their position relative to the overall route, landmarks, and the other party's location, enabling them to verify they are on the correct path with greater confidence.
Data Source
AI summary
An apparatus and a method search a route using a portable terminal. A controller establishes a call connection with another party and exchanges positional information with the other party. An analyzing unit analyzes the route information using a first positional information of the portable terminal and a second positional information of the other party. A displaying unit outputs the route information analyzed by the analyzing unit. The controller provides the route information analyzed by the analyzing unit.
