Hub-Dialogue System for Seamless IoT Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dialogue systems for IoT devices have a closed accessibility issue, requiring users to remember and manually select the correct dialogue system and command syntax for each device, reducing user convenience.
Innovation Solution
A hub-dialogue system that processes user intentions, connects with external dialogue systems via wireless communication, generates and transmits command sentences to control IoT devices, allowing users to input commands once without knowing the specific dialogue system or syntax, using a speech processor, communicator, and controller to determine the appropriate external dialogue system and convert user dialogue into voice signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed dialogue system is used where only the company's own dialogue system can control IoT devices, then the device control reliability is improved, but the user convenience deteriorates because users must remember which dialogue system is linked to each device and use specific commands
Solution Approach 1:
The patent introduces a hub device as an intermediary between the user and multiple external dialogue systems. The hub receives user speech inputs, determines the appropriate external dialogue system and command syntax, converts the speech into the required format, and transmits it to the target system. This mediator approach maintains reliable device control through each specific dialogue system while hiding the complexity from users, thereby improving user convenience without sacrificing control reliability.
2Adaptability or versatility
If multiple external dialogue systems are supported, then the system versatility is improved, but the system complexity increases due to the need to manage multiple dialogue systems and their specific commands
Solution Approach 1:
The patent segments the complexity management function into a dedicated hub device that handles multiple external dialogue systems. Each external dialogue system maintains its own processing logic, while the hub provides a unified interface for users. The hub segments the tasks of speech recognition, dialogue system selection, command generation, and transmission, thereby supporting multiple dialogue systems and devices without proportionally increasing overall system complexity.
Solution Approach 2:
The hub device is designed with universal functionality to interface with multiple different external dialogue systems and various IoT devices simultaneously. It can identify and adapt to different dialogue systems, generate appropriate commands for each, and manage multiple device connections through a single unified platform, thereby achieving high versatility without requiring separate systems for each dialogue platform.
3Measurement precision
If users must manually select the correct dialogue system and command syntax for each device, then the command precision is improved, but the user time consumption increases
Solution Approach 1:
The hub device performs self-service by automatically analyzing user speech inputs, identifying the intended target device, selecting the appropriate external dialogue system, and generating the correct command syntax without user intervention. The system autonomously handles the complex process of matching devices with their corresponding dialogue systems and commands, thereby maintaining precise device control while eliminating the time users would otherwise spend manually selecting systems and formulating correct commands.

AI summary
A hub-dialogue system includes a speech processor configured to determine a user intention that is included in inputted user dialogue. A communicator is configured to connect a local speaker corresponding to an external dialogue system through wireless communication. A controller is configured to determine the external dialogue system corresponding to the user intention from among a plurality of external dialogue systems, to generate a command sentence indicating the user intention, to convert the command sentence to a voice signal, and to control the communicator to transmit the voice signal to the local speaker corresponding to the determined external dialogue system.
