Location Message Extraction for Group Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In group navigation scenarios, existing instant messaging and search engine methods are inefficient for providing timely and relevant geographical information, especially when members are traveling to a common destination, as they often result in information overload, outdated data, and difficulty in finding accurate directions without knowing the current location or destination name.
Innovation Solution
A method and system that acquires current position information from user equipment and sends messages to a server to direct group members to a shared destination, using GPS or other positioning technologies, allowing members to pin messages at specific locations for others to receive when passing by, ensuring up-to-date and relevant guidance within a valid time period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If group members exchange messages through instant messaging to navigate to a destination, then they can communicate and ask for help, but it becomes difficult to search for useful information from a tremendous amount of messages
Solution Approach 1:
The patent extracts location-based navigation information from the general group chat messages and separates it into a dedicated location message system. When a user sends a location message, it is extracted from the ordinary conversation flow and stored as a distinct entity with geographic coordinates, allowing other users to access navigation information without sifting through irrelevant chat content.
Solution Approach 2:
The patent introduces a server as an intermediary between users and navigation information. The server receives location messages from users, stores them with geographic data, and delivers them to other users based on their current locations. This intermediary system filters and manages navigation information separately from general group communication, solving the information searchability problem.
2Reliability
If users turn to a website or searching engine for navigation help, then they can search for information about the destination, but the search result is not up to date, not related to any geographical point, and requires knowing the destination name
Solution Approach 1:
The patent enables users to send their own location information to the server, which then automatically provides navigation guidance to other group members. Users don't need to manually search for destination information - the system automatically delivers relevant location data based on the sender's transmitted position and the receiver's current location, making the process self-service and eliminating the need for keyword searches.
Solution Approach 2:
The patent changes the search parameter from requiring destination names (text-based search) to using geographic coordinates (location-based delivery). Instead of users needing to know and search for destination names, the system uses GPS coordinates and automatic location matching to deliver navigation information, making it easier to obtain accurate and up-to-date guidance without knowing the destination name in advance.
3Adaptability or versatility
If a group chat is used for navigation, then members can communicate freely, but it is difficult to find useful information from a tremendous amount of messages
Solution Approach 1:
The patent segments the group communication system into two distinct channels: general chat messages and location messages. Location messages are treated as a separate category with special handling - they are stored with geographic data, delivered based on location matching rather than chronological order, and can be independently accessed. This segmentation preserves the flexibility of general communication while ensuring navigation information remains accessible and organized.
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
This solution provides real-time, location-specific guidance to group members, reducing confusion and time wastage by ensuring that information is relevant, up-to-date, and accessible to all, while accommodating users with disabilities through voice, text, or video messages, enhancing navigation efficiency and inclusivity.
Implementation Method 1
acquires current position information of the first member using global positioning system (GPS) or other positioning technologies
Data Source
AI summary
A method for navigating is provided. The method comprises, in response to input on user equipment of a first member of a group who is travelling to a destination, one or more processors acquiring current position information of the user equipment of the first member. The method further includes one or more processors sending a first message to a server. The first message includes the current position information indicating an area where the first member was when the first message was sent. The first message is for directing a member of the group, who receives the first message when passing the area, to the same destination as the first member.
