Dialog Manager for Distributed Automation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed home automation systems face complexity due to uncoordinated operation of 'smart' devices, requiring users to interact with each device separately, leading to inefficiencies in managing multiple devices.
Innovation Solution
A user interface device that receives service messages from home automation devices, identifies their states, generates natural language output messages using stored templates, and prioritizes messages for presentation to users, allowing for coordinated control and simplified interaction with multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple smart devices operate independently in a distributed network, then device autonomy and flexibility are improved, but system complexity and user interaction difficulty increase
Solution Approach 1:
The patent introduces a gateway device as an intermediary between multiple smart devices and the user. The gateway receives service messages from various devices, manages their coordination, and presents unified notifications to the user. This mediator resolves the contradiction by maintaining device autonomy while reducing system complexity from the user's perspective through centralized message management and coordination.
2Measurement precision
If users interact with each smart device separately using imperative commands, then device control precision is improved, but user effort and time consumption increase
Solution Approach 1:
The patent merges multiple device interactions into a unified notification system. Instead of requiring separate imperative commands for each device, the gateway consolidates service messages from multiple devices into unified notifications that can be managed collectively. This combining approach maintains control precision through structured message formats while significantly reducing user time consumption by eliminating the need for sequential device-by-device interaction.
3Stability of the object's composition
If a centralized control system is used to coordinate devices, then system coordination is improved, but system architecture complexity and single point of failure risk increase
Solution Approach 1:
The patent segments the control architecture into two layers: a simple message forwarding layer at the gateway and autonomous device layers. The gateway is segmented to handle only notification routing and coordination logic, while device-specific control remains distributed. This segmentation achieves system coordination without creating a complex centralized architecture, as each segment maintains appropriate autonomy while contributing to overall system coherence.

AI summary
A method for generating a user interface with a user interface device in a distributed automation system includes receiving a service message from a home automation device in the distributed automation system, identifying a state of a dialog manager of the user interface device in response to receiving the service message, and generating a natural language output message based at least in part on a device identifier parameter in the service message and a plurality of natural language templates stored in the memory in response to the dialog manager being in an idle state. The method further includes storing the service message in a priority queue in the memory based on a priority level parameter corresponding to the service message in response to the dialog manager being in an active state.
