RFID-Based User Presence Tracking for Automated Message Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no reliable method to determine the most effective communication medium for reaching a user, as users often switch between devices and locations, leading to missed messages due to the tedious process of forwarding notifications.
Innovation Solution
The integration of RFID technology to track user movement and proximity to communication devices, allowing for programmatic actions and automated message routing based on user location, using a central controller to coordinate communication systems and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual message forwarding is used to ensure messages reach the user, then message delivery reliability improves, but user convenience deteriorates due to the tedious process
Solution Approach 1:
The system automatically monitors user presence across multiple communication devices and autonomously routes messages to the most appropriate device without requiring user intervention. The presence information management system continuously tracks device availability and automatically forwards messages based on current user location and device status.
Solution Approach 2:
The system implements continuous feedback loops by monitoring user presence status across devices and using this information to dynamically adjust message routing decisions. Presence information is continuously updated and fed back to the message routing system to ensure messages are always directed to the currently most accessible device.
2Reliability
If multiple communication devices are used to ensure message delivery, then message delivery reliability improves, but system complexity increases
Solution Approach 1:
The presence information management system serves multiple functions: it tracks user presence across devices, determines optimal message routing, and coordinates message forwarding across different communication platforms. This single multi-functional system replaces what would otherwise require separate complex systems for presence tracking, message routing, and device coordination.
Solution Approach 2:
The presence information management system acts as an intermediary layer between multiple communication devices and the message routing process. It consolidates presence information from various devices and presents a unified view to the routing system, simplifying the overall architecture by centralizing the coordination function.
3Productivity
If automated message routing is implemented, then productivity improves by reducing manual forwarding, but measurement precision requirements increase for tracking user location
Solution Approach 1:
The system monitors presence information across multiple communication devices simultaneously, using more tracking data than strictly necessary for basic location identification. This excessive monitoring ensures high precision in determining user location by cross-referencing multiple device signals and presence states.
Solution Approach 2:
The system pre-establishes presence information tracking and device status monitoring before message routing decisions are required. By continuously maintaining updated presence information across all devices in advance, the system eliminates the need for precise real-time location measurement when messages need routing.
