Location-Based Reminder System with Server Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reminders lack the ability to specify both the time and location for triggering, limiting user flexibility in managing reminders across different locations and devices.
Innovation Solution
The system allows users to set location-based reminders by specifying a venue or geographic coordinates, enabling reminders to be triggered when a device enters or exits a designated location, and synchronizing these reminders across multiple user devices through a server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional reminders are used, then reminders can be set with simple time triggers, but users lack flexibility in managing reminders across different locations and devices
Solution Approach 1:
The patent adds a location dimension to traditional time-based reminders by enabling users to specify geographic coordinates or venue names as trigger conditions. This allows reminders to be activated based on device location rather than only time, providing flexibility across different locations and devices while maintaining the core reminder functionality.
Solution Approach 2:
The reminder system is designed to work across multiple devices (mobile phones, tablets, computers) and locations simultaneously. Users can configure reminders to trigger on specific locations, and the system automatically delivers appropriate reminders to relevant devices based on device location, making the system universally applicable across different platforms and scenarios.
2Adaptability or versatility
If location-based reminders are implemented, then users gain location-specific trigger options, but the system complexity increases due to location services and server coordination
Solution Approach 1:
A server computer acts as an intermediary between users and their devices, managing location-based reminder logic centrally. The server receives location data from devices, matches it with configured reminder conditions, and pushes appropriate reminders to the correct devices. This intermediary approach simplifies client-side complexity while enabling sophisticated location-based functionality.
Solution Approach 2:
The patent replaces complex client-side location matching logic with server-based processing. Instead of each device independently managing complex location queries and device identification, the system uses location services to provide simplified location data to the server, which then handles the complex matching and notification distribution logic.
3Productivity
If reminders are triggered based on location, then unnecessary notifications are reduced by showing only relevant reminders at the correct location, but location tracking and verification add system overhead
Solution Approach 1:
The system uses approximate location matching rather than requiring precise location tracking. By accepting location data at reasonable accuracy levels and using server-based geofencing, the system can efficiently determine when a device enters or exits a designated area without continuous high-precision tracking, reducing energy consumption while maintaining notification effectiveness.
Data Source
AI summary
Methods, program products, and systems for location-based reminders are disclosed. A first user device can receive an input specifying that a reminder be presented at a given location. The first user device can provide a reminder request, including type and content of the reminder and the location, to a server computer for pushing to one or more user devices. A second user device, upon receiving the reminder request, can determine a device location of the second user device. If the given location matches the device location, the second user device can present the reminder in a user interface.
