Signal Replication for Non-Invasive User Interaction Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring user interactions with radio and television receivers are inadequate in collecting detailed data on new services and interactions, and are not capable of diagnosing malfunctions in a non-invasive manner, especially with complex systems and diverse content sources.
Innovation Solution
A device and method for collecting user interface status information by replicating electrical signals between the user interface and processing means, allowing for the collection of versatile interaction data without requiring software updates or significant hardware modifications, using a replication means to obtain and decode electrical signals and a collection means to store or transmit this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing detection systems are extended to monitor new services and interactions, then measurement capability is improved, but device complexity and risk of modification increase
Solution Approach 1:
The system is divided into separate functional modules: a signal replication unit that copies electrical signals from the connection means, a collection unit that processes the replicated signals, and the original receiver system. This segmentation allows the monitoring functionality to be added without modifying the complex central parts of the receiver, thus improving measurement capability while avoiding increased device complexity in the core system.
Solution Approach 2:
A signal replication mechanism is introduced as an intermediary between the connection means and the collection unit. This intermediary copies the electrical signals carrying user interface status information without interrupting or modifying the original signal flow, enabling monitoring of new services and interactions while keeping the original system architecture intact and avoiding the risks associated with modifying complex receiver software.
2Loss of information
If signal replication is implemented to monitor user interactions, then data collection capability is improved, but system invasiveness increases
Solution Approach 1:
Instead of directly accessing or modifying the electrical signals in the connection means, the system creates a copy of these signals through the replication mechanism. This copying approach enables comprehensive data collection about user interactions with new services while maintaining the original signal integrity and minimizing intrusion into the receiver's internal operations, thus reducing system invasiveness.
