Group-Based Location Notification Service for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless devices lack efficient methods to facilitate location-based and group-based operations, such as notifying users when they are at the same location or within a specific distance, which limits their ability to coordinate meetings or interactions.
Innovation Solution
A system and method that employs location tracking techniques, including GPS, cell-tower triangulation, and user self-reporting, to identify when users within a group are at the same location, and notifies other group members through a data processing service that converts and transmits relevant information, enabling visual and audible notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If location tracking and group notification operations are implemented on wireless devices, then users can efficiently coordinate meetings and interactions, but data traffic and bandwidth usage increase
Solution Approach 1:
The system pre-establishes groups containing identities of multiple users and pre-configures notification data indicating when users should be notified about current locations. This preliminary setup allows the system to efficiently determine and notify users of co-location events without requiring extensive real-time data processing or communication when location events occur.
2Measurement precision
If continuous location monitoring is performed to identify when users are at the same location, then notification accuracy is improved, but energy consumption increases
Solution Approach 1:
The system performs location determination operations periodically or on-demand rather than continuously. The data processing service determines whether wireless data processing devices of two or more users are at the same location or within a particular distance by checking location data at appropriate intervals, rather than maintaining constant monitoring, thus reducing energy consumption while maintaining notification accuracy.
3Loss of information
If detailed location information is transmitted to notify users, then notification usefulness is improved, but user privacy is compromised
Solution Approach 1:
The system extracts only the essential notification data needed for user coordination - specifically, information about when users are at the same location or within a particular distance. Rather than transmitting detailed continuous location information, the system identifies and transmits only the relevant co-location events, maintaining notification usefulness while protecting user privacy through selective information extraction.
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 efficiently coordinate meetings and interactions by accurately determining and notifying group members of shared locations, reducing unnecessary data traffic and bandwidth usage while maintaining user privacy settings.
Implementation Method 1
A GPS receiver within a GPS-enabled wireless device can determine the device's precise location, speed, and direction by reading precise microwave signals transmitted from a constellation of Medium Earth Orbit satellites

AI summary
A system and method are described for location-based and group-based operations on a data processing device. For example, a computer-implemented method according to one embodiment of the invention comprises: establishing a group containing identities of a plurality of users within the group and notification data indicating when other users are to be notified about current locations of the users in the group; determining whether wireless data processing devices of two or more users of the group are at the same location or within a particular distance of the location; identifying the users and the location; and notifying other users in the group of the identity of the users and the location.
