Method and apparatus for setting destination in navigation terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in setting a destination in navigation systems when they do not know the correct address or geographical position of the destination, especially when the destination is a specific location like a highway or mountain slope.
Innovation Solution
A method and apparatus that allow users to set a destination by receiving and processing location information from a message, using a communication interface and processor to identify and obtain location data, and then displaying a route between the start and destination locations, even if the destination is not a specific region or feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users input destination coordinates directly, then the navigation system can calculate routes, but users cannot set destinations when they do not know the correct address or geographical position
Solution Approach 1:
The patent introduces an intermediary mechanism (message receiving module) that mediates between the user's lack of destination knowledge and the navigation system's requirement for location data. Messages containing destination information from other users or systems serve as intermediaries, allowing users to set destinations without knowing addresses or coordinates.
Solution Approach 2:
The system enables self-service by allowing users to share and exchange destination information through messages. Users can independently obtain destination data from message contents without requiring assistance from navigation operators or external services, making the destination setting process autonomous.
2Measurement precision
If the navigation system requires specific address or region data, then route calculation accuracy is maintained, but destinations like highway positions or mountain slopes cannot be set
Solution Approach 1:
The patent applies universality by making the message-based destination setting mechanism applicable to all types of destinations, whether they are specific regions, features, or transient locations like highway positions and mountain slopes. The system handles diverse destination types through a unified message processing approach.
Solution Approach 2:
The system changes the parameter representation of destination information from structured address data to flexible message content. By extracting location information from unstructured or semi-structured message texts, the system adapts to various destination types without requiring standardized address formats.
3Measurement precision
If users manually search map data to set destinations, then accurate location selection is possible, but the process becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by having other users or systems pre-process and share destination information in messages before the receiving user needs it. The destination location data is prepared in advance within message contents, eliminating the need for users to perform time-consuming map searches when setting destinations.

AI summary
A method and an apparatus are provided for a displaying a route in a first electronic device. A message is received from a second electronic device. First location information is identified in the received message. Based at least on identifying the first location information in the received message, the first location information is obtained from the received message for setting a destination location. Second location information of the first electronic device is obtained. Based at least on the obtained first location information from the received message and the obtained second location information of the first electronic device, a start location and the destination location are set. Based at least on obtaining route information between the start location and the destination location, a route representing the obtained route information between the start location and the destination location is displayed on a display of the first electronic device.
