Navigation Terminal Destination Setting via Shared Location Messages
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 for specific or featureless locations like highway points or mountain slopes.
Innovation Solution
A method and apparatus that allow a mobile terminal to receive location information from an external device via a message, using a wireless communication unit to obtain and set position coordinates as destination coordinates for route calculation, enabling correct destination setting even without specific address knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If destination coordinates are set only by user input (direct address input or map search), then the navigation system can calculate routes to specific addresses, but the user cannot set destinations when they do not know the correct address or geographical position
Solution Approach 1:
The patent introduces an intermediary mechanism (message reception function) that mediates between the external device and the navigation terminal. The mobile terminal receives location information from an external device via message, obtains position coordinates from the message, and sets these coordinates as destination coordinates, thereby enabling destination setting without requiring the user to know the address
Solution Approach 2:
The navigation terminal automatically processes the received message to extract position coordinates and set the destination without requiring manual address input or map searching by the user. The system serves itself by automatically converting the received location information into navigable destination coordinates
2Reliability
If the navigation terminal requires correct address input or map data search to set destination, then route calculation can be performed for specific regions, but it becomes difficult to set destinations for featureless locations like highway points or mountain slopes
Solution Approach 1:
The patent makes the destination setting function universal by enabling it to handle multiple types of location specifications. The mobile terminal can receive and process location information from external devices for various types of destinations including specific addresses, highway points, mountain slopes, and other featureless locations, making the navigation system adaptable to diverse destination scenarios
Data Source
AI summary
A method and apparatus are provided for setting a destination in a mobile terminal is provided. The mobile terminal receives a message including location information from an external device. The mobile terminal obtains the location information from the message. Position coordinates corresponding to the location information are set as position coordinates of a destination related to a route.
