Navigation Terminal Destination Setting Using Shared Position Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require users to input correct destination address or geographical position, which can be difficult when the user is unfamiliar with the destination or when the destination is a specific location on a highway or mountain.
Innovation Solution
A method and apparatus that allow users to set a destination by receiving and selecting position information from a multimedia message, which includes GPS signals from other devices, enabling the navigation terminal to calculate and display a route to the selected destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the navigation system requires users to input correct destination address or geographical position, then the navigation accuracy is improved, but the ease of operation deteriorates when users are unfamiliar with the destination
Solution Approach 1:
The patent introduces an intermediary mechanism where position information is transmitted through multimedia messages from other terminals. Instead of requiring users to directly input or search for destination coordinates, the system mediates the destination setting process by receiving position data from contacts who know the location, thus resolving the contradiction between accuracy and ease of operation
Solution Approach 2:
The patent applies preliminary action by having other terminals pre-calculate and store position information before the navigation query is made. The position data is prepared in advance and transmitted via multimedia message, so when the user receives it, the destination is already determined and ready for navigation, eliminating the need for the user to perform complex location searches
2Measurement precision
If the navigation system uses GPS receiver or user input to set current position coordinates, then the positioning accuracy is improved, but the adaptability deteriorates for destinations that are not specific regions or features
Solution Approach 1:
The patent uses copying by transmitting position information as data embedded in multimedia messages. Instead of requiring the destination to be a recognizable geographical feature or address, the system copies the exact position coordinates from the sender's terminal and transmits them, allowing any location (including specific points on highways or mountains) to be set as a destination without requiring it to be a predefined region or feature
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to correctly set a destination even without knowing the exact address or geographical coordinates, facilitating navigation to specific locations that may not be easily identifiable.
Implementation Method 1
A navigation terminal using a Global Positioning System (GPS) receiver included in the navigation terminal or a user input can set the current position coordinates
Data Source
AI summary
A method and an apparatus are provided for a displaying a route in a first electronic device. A first message is received from a second electronic device. First position information included in the first message is identified. The first position information includes position information of the second electronic device. A user input for selecting the first message from a plurality of messages is received. Position information of the first electronic device is calculated. Route information between a start position and a destination position is received from a navigation server. The start position corresponds to the position information of the first electronic device and the destination position corresponds to the position information of the second electronic device. Based at least on receiving the route information from the navigation server, a route representing the received route information between the start position and the destination position is displayed on the first electronic device.
