Solution Overview
Problem
Existing methods for location sharing among users on electronic maps are inadequate, as they provide limited information and fail to effectively meet the demands of users for quick and efficient position sharing.
Innovation Solution
A method and system that determine a user's motion state based on their location information, acquire direction information using devices like GPS and electronic compasses, and share this information with other users, allowing for graphical representation on a map interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If location sharing is implemented using existing methods, then basic position information can be shared, but the information is limited and does not meet user demands for quick and efficient position sharing
Solution Approach 1:
The patent segments location information into multiple components: basic position coordinates, motion state (moving/stationary), direction information (orientation angle or movement direction), and velocity data. This segmentation allows comprehensive location sharing while keeping each data element simple and manageable, resolving the contradiction between information completeness and system complexity
Solution Approach 2:
The patent adds dimensional information to traditional 2D location sharing by incorporating directional data (orientation or movement direction) as a new dimension. This transforms location from a simple coordinate point to a more rich representation including position and direction, enhancing information completeness without significantly increasing system complexity
2Measurement precision
If motion state determination is performed using GPS and electronic compasses, then accurate direction information can be obtained, but software and hardware requirements increase
Solution Approach 1:
The patent implements dynamic direction determination by detecting motion state and switching between two modes: when stationary, it uses electronic compass orientation data; when moving, it calculates movement direction from sequential GPS position data. This dynamic approach maintains high measurement precision while reducing hardware requirements, as not all devices need electronic compasses if they can provide accurate GPS position data
Solution Approach 2:
The system uses readily available device sensors (GPS and electronic compass) that are already present in modern mobile devices. By leveraging these existing components for direction determination, the patent achieves accurate direction information without requiring additional specialized hardware, thus maintaining low hardware requirements while ensuring measurement precision

AI summary
Method and server system for location sharing are disclosed. The server system receives information items related to a current location of the first mobile device associated with a first user of the social networking platform. After comparing the current location of the first mobile device with a previous location of the first mobile device and determining an orientation and/or velocity of the first mobile device at the current location, the server system sends the determined orientation and/or velocity of the first mobile device to the second mobile device associated with a second user of the social networking platform, wherein the second mobile device displays distinct visual indicators corresponding to the current location, orientation and velocity of the first mobile device, respectively, on an interactive map interface.
