Vehicle Navigation System SMS Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems require manual entry of destination addresses and phone numbers, which is cumbersome and time-consuming, and lack a method to capture and synchronize navigational data from SMS messages for use in vehicle navigation, leading to duplication of information entry.
Innovation Solution
A system and method that periodically polls a wireless device for new SMS messages, extracts and saves telephone numbers and addresses to an onboard vehicle navigation system, allowing automatic routing and call generation, and distinguishes new from previously stored icons using visual formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual entry of destination addresses and phone numbers is used, then the navigation system can store and process the data, but the process is cumbersome and time-consuming
Solution Approach 1:
The patent introduces an intermediary system that captures SMS messages from mobile devices and automatically extracts navigational data (addresses, phone numbers) to transfer to the vehicle's navigation system. This intermediary automation eliminates the need for manual data entry while maintaining data accuracy, directly resolving the contradiction between ease of operation and time loss.
2Extent of automation
If SMS messages are received and processed, then navigational data can be automatically captured, but the system complexity increases
Solution Approach 1:
The patent extracts and isolates the SMS message processing function as a separate module within the navigation system. By taking out the data extraction and synchronization operations into a dedicated component, the system achieves automation while managing complexity through modular architecture, allowing the core navigation functions to remain relatively simple.
3Loss of information
If multiple address icons are displayed on the map screen, then users can see all location information, but it becomes difficult to distinguish new addresses from previously stored ones
Solution Approach 1:
The patent implements visual differentiation of address icons based on their status (new versus previously stored). By changing the visual characteristics (such as color, brightness, or icon type) of icons representing new addresses, the system maintains complete information display while making new data easily distinguishable through visual cues, resolving the contradiction between information completeness and data identification difficulty.
Data Source
AI summary
A system and method are provided for receiving navigational data via a wireless messaging service on a navigation system. The system and method provides a way to send requests for destination information via the wireless messaging service and capture navigational data from the responsive message received, such as addresses, telephone numbers, or email addresses, and then utilize that data for navigational routing, generation of telephone calls, emailing and the like, from the vehicle's navigation system. A wireless device can be paired with the navigation system over a Bluetooth communication link, wherein the navigation system periodically polls the wireless device for newly received messages. In one embodiment, the NAVI displays icons on a map that correspond to the extracted addresses from the messages received in relation to the vehicle's current location. The icons can be shown in a plurality of visual formats to distinguish previously viewed locations from newly received ones.
