Navigation Device Automatic Destination Setting via Text Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require manual input of destinations, which can be inconvenient and unsafe for drivers when receiving location information from third parties, as they need to directly interact with the navigation device to set new destinations.
Innovation Solution
A method and system that allows a terminal device to extract place-associated information from text messages, such as addresses or region names, and transmit this information to a navigation device for setting a destination, enabling automatic updating of navigation paths without direct user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of destination is required in navigation systems, then the navigation device can accurately set destinations, but the operation becomes inconvenient and unsafe for drivers
Solution Approach 1:
The patent introduces a terminal device (such as a smartphone) as an intermediary between the user and the navigation system. The terminal device receives text messages containing location information, extracts the destination, and transmits it to the navigation device. This mediator handles the complex interaction, allowing the driver to simply receive messages without manual navigation operations, thus improving both ease of operation and driving safety
Solution Approach 2:
The system enables automatic destination setting by having the terminal device automatically extract location information from received text messages and transmit it to the navigation device without requiring driver intervention. The extraction and transmission processes are performed autonomously, reducing manual input requirements and enhancing driving safety
2Extent of automation
If automatic extraction of place information from text messages is implemented, then the destination setting process is automated, but the system complexity increases
Solution Approach 1:
The terminal device serves as an intermediary that performs the complex automatic extraction and transmission tasks. By offloading these functions to the terminal device, the navigation device itself does not need to implement complex text processing algorithms, thus achieving automation while managing system complexity through functional distribution
Solution Approach 2:
The terminal device performs multiple functions: receiving text messages, extracting location information, and transmitting data to the navigation device. This multi-functional approach consolidates complex operations in a single device that is already present in most users' vehicles, avoiding the need to add specialized components to the navigation system
3Productivity
If place-associated information is extracted from text messages, then manual input of destination is reduced, but information extraction accuracy must be maintained
Solution Approach 1:
The system implements feedback mechanisms where the terminal device extracts place-associated information from text messages and transmits it to the navigation device, which then uses this information to set the destination. The feedback loop ensures that extraction accuracy is maintained by verifying the extracted information against the navigation device's database before finalizing the destination setting

AI summary
A navigation device, a system for inputting a place, and a method for inputting a place to the navigation device implement inputting a place to a navigation device communicating with a terminal device, searching for and extracting place-associated information from text received by the terminal device. If the place-associated information is extracted from the text, the implementation carries out transmitting, by the terminal device, the text or the place-associated information detected from the text to the navigation device; and setting, by the navigation device, a place obtained on basis of the place-associated information to a destination.
