Server-Mediated IoT Context Data Mirroring for Device Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Things (IoT) environment, there is a need for efficient methods to control devices based on user circumstances without human intervention, particularly in scenarios like smart homes and vehicles, where context data from one device needs to be used to trigger actions on another device.
Innovation Solution
A method and device configuration that involves a server device obtaining context data from a client device, determining events based on this data, and transferring relevant information to another client device to perform mirroring services, such as changing screen displays or executing applications, based on pre-stored user information and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If context data is continuously monitored and processed to determine user events, then device control automation is improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent introduces a server as an intermediary component that receives context data from a first client device, processes it to determine user events, and sends control commands to a second client device. This mediator architecture distributes the computational burden and complexity away from individual client devices, allowing them to remain relatively simple while achieving high automation through the centralized server's event processing capabilities.
2Loss of information
If mirroring service is established between devices, then information synchronization is improved, but network bandwidth and communication overhead increase
Solution Approach 1:
The patent extracts and transfers only the essential information about determined events from the first client device to the second client device through the server, rather than continuously mirroring all data streams. This selective information extraction maintains synchronization of critical event data while minimizing network bandwidth consumption by transmitting only necessary control commands and event information.
3Speed
If context data processing is performed in real-time, then responsiveness to user events is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary actions by pre-processing and analyzing context data to determine user events before actual device control actions are required. The server maintains readiness to process events by having the event determination logic prepared and configured in advance, allowing rapid response to user events without the need for intensive real-time computation during the actual event occurrence, thus reducing instantaneous energy consumption while maintaining high responsiveness.
