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 for specific or featureless locations like highway points or mountain slopes.
Innovation Solution
A method and apparatus that allow users to set a destination by receiving and processing position information from a second electronic device via a multimedia message, enabling the calculation and display of a route between the user's current position and the destination, even if the destination coordinates are not directly input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly input address or search stored map data to set destination, then destination coordinates can be set, but users must know the correct address or geographical position of the destination which is not always available
Solution Approach 1:
The patent introduces an intermediary mechanism (message receiving function) that mediates between the user's lack of destination information and the navigation system's requirement for destination coordinates. By receiving messages containing destination information from other devices, the system bridges the information gap without requiring the user to manually know or input the destination address.
Solution Approach 2:
The navigation terminal automatically processes received messages to extract and set destination coordinates without requiring manual user input. The system serves itself by automatically converting message content into navigable destination data, reducing the burden on the user who merely needs to send or receive a message rather than perform complex address input or map searching.
2Measurement precision
If users manually input destination coordinates through address or map search, then accurate destination setting is achieved, but the process becomes complex and time-consuming when destination information is unknown
Solution Approach 1:
The patent applies preliminary action by having destination information pre-packaged in messages before the navigation process begins. Instead of requiring users to perform time-consuming address input or map searching at the moment of navigation, the destination data is prepared in advance within the message structure, allowing for rapid extraction and immediate route calculation.
Solution Approach 2:
The patent replaces the mechanical interaction of manual address input and map searching with an automated electronic message processing system. The system substitutes the manual mechanical process of typing addresses or navigating map interfaces with an automated electronic extraction and processing of destination coordinates from received messages, significantly reducing both time and operational complexity.

AI summary
A method and apparatus are provided for displaying information in a first electronic device. A message is received from a second electronic device. In response to determining that the message includes information corresponding to a location of the second electronic device, information corresponding to a location of the second electronic device is obtained from the received message. A start point and a destination point are set based at least in part on position information of the first electronic device and the information corresponding to the location of the second electronic device. In response to identifying a route between the start point and the destination point, information representing the identified route between the start point and the destination point is displayed on a display of the first electronic device.
